From 098e32eadf3430c803a38df3a50b8a0b98b8e056 Mon Sep 17 00:00:00 2001 From: Alessandro Nocentini Date: Sun, 12 Apr 2026 01:15:28 +0200 Subject: [PATCH 001/181] perf+fix: wallet batch loading, quantum-safe asset issuance, auto-sweep Performance: - WalletManager: add getAddressBatch() for single Keystore decrypt per N addresses - RavencoinPublicNode: add getTotalBalance(), getTotalAssetBalances(), getAddressStatusBatch(), getAssetMetaBatch() for pipelined batch TLS calls - discoverCurrentIndex(): batch size 20 with getAddressBatch + getAddressStatusBatch (was 5 individual calls each) - sweepOldAddressesInternal(): use getAddressBatch + getAddressStatusBatch instead of per-address calls - loadOwnedAssets(): pre-fetch all IPFS hashes in one batch RPC call, raise Semaphore from 3 to 8 - WalletPollingWorker: use getAddressBatch + getTotalBalance + getTotalAssetBalances - NfcCounterCache: lazy init to avoid blocking main thread at startup - CONNECT_TIMEOUT_MS: 12000ms -> 5000ms Bug fixes: - Asset issuance: owner token (ROOT!, ROOT/SUB!) was sent to toAddress instead of changeAddress; if toAddress was an external recipient the brand permanently lost sub-asset issuance rights - Asset issuance: redirect toAddress to nextAddress when issuing to own wallet, asset lands quantum-safe immediately without extra sweep tx - WalletPollingWorker: trigger sweepOldAddresses() on any detected incoming transfer, consolidates HAS_OUTGOING addresses in background (app closed) - loadWalletInfo(): run discoverCurrentIndex() when balance is null (fixes Brand app showing 0 balance with same mnemonic as Consumer) - Remove redundant loadOwnedAssets() call from initWallet() --- .gitignore | 3 + .../main/java/io/raventag/app/MainActivity.kt | 244 +++- .../io/raventag/app/nfc/NfcCounterCache.kt | 36 +- .../app/wallet/RavencoinPublicNode.kt | 374 +++++- .../raventag/app/wallet/RavencoinTxBuilder.kt | 476 +++++++- .../io/raventag/app/wallet/WalletManager.kt | 1042 +++++++++++++++-- .../app/worker/WalletPollingWorker.kt | 35 +- 7 files changed, 1974 insertions(+), 236 deletions(-) diff --git a/.gitignore b/.gitignore index d110ba7..45d69e0 100644 --- a/.gitignore +++ b/.gitignore @@ -66,3 +66,6 @@ screenshots/ # Qwen Code configuration (local only) .qwen/ + +# Legal documents (personal data) +docs/associazione/ diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index 098b0b3..b9ef6f1 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -554,31 +554,59 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { * requests via a semaphore) and update the list progressively. */ fun loadOwnedAssets() { - val address = walletManager?.getAddress() ?: return + val wm = walletManager ?: return viewModelScope.launch { assetsLoading = true assetsLoadError = false try { - // 1.

Chain: getLocalBalance() fails -> balance==null -> discoverCurrentIndex() triggered -> getAddressBatch() returns emptyMap() -> loop breaks with lastUsed=-1 -> setCurrentAddressIndex(0) -> next balance check returns 0 RVN. Fix: if first batch is empty, return stored index unchanged. Also never decrease the stored index (transient failure != rollback). 2. loadWalletInfo() reset walletInfo to balanceRvn=0.0 at the start of every load, flashing 0 on screen during reload. Fix: preserve existing balance/address while loading; only replace with new data on success, keeping stale data visible if the network call fails. 3. initWallet() was called unconditionally from onCreate(), relaunching all loading coroutines even when the ViewModel already had data (e.g. after a screen rotation where the Activity is recreated but the ViewModel survives). Fix: skip loadWalletInfo() if walletInfo != null. Also: keep asset preview images on refresh (IPFS content is immutable, no need to clear and reload images already in memory or disk cache). --- .../main/java/io/raventag/app/MainActivity.kt | 50 +++++++++++++------ .../io/raventag/app/wallet/WalletManager.kt | 19 +++++-- 2 files changed, 52 insertions(+), 17 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index b9ef6f1..b38669b 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -580,24 +580,41 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { }.sortedWith(compareBy({ it.type.ordinal }, { it.name })) } -

buildAndSignRvnSendWithAssetSweep: - RVN change (P2PKH) was placed after OP_RVN_ASSET outputs, violating Ravencoin consensus ordering: all P2PKH outputs must precede asset outputs. Consequence: node accepted the tx but ignored asset transfers, RVN moved but assets stayed on the old address. RavencoinTxBuilder - buildAndSignMultiAddressSend (new function): - Same P2PKH-after-OP_RVN_ASSET ordering bug, now fixed. - Dust hardcoded to 600 sat for every asset output regardless of input dust. Ravencoin requires: if input asset UTXO has 0 sat, output must also be 0 sat (assets issued with dustOut=0 would trigger bad-txns-asset-transfer-amount and the tx would be rejected, assets not moved). Fixed: dust derived from input UTXO satoshis per asset. WalletManager - sweepOldAddressesInternal: - Funding transaction used hardcoded fee of 2000 sat, far below minimum relay fee (200+ sat/byte * ~226 bytes = 45000+ sat). Funding tx was rejected and asset-only addresses could not be swept. Fixed: fee calculated from getMinRelayFeeRateSatPerByte(). WalletManager - healAndSweepTarget: - Funding transaction signed with the TARGET address key pair (index being swept) instead of the CURRENT address key pair (owner of the UTXOs being spent). Invalid signatures caused the funding tx to be rejected every time. Fixed: separate getKeyPair(currentIndex) used for the funding tx, zeroed in finally block. Fee also now calculated dynamically from satPerByte. --- .../main/java/io/raventag/app/MainActivity.kt | 27 +- .../raventag/app/ui/screens/WalletScreen.kt | 343 ++++++++++-------- .../app/wallet/RavencoinPublicNode.kt | 110 +++++- .../raventag/app/wallet/RavencoinTxBuilder.kt | 142 +++++++- .../io/raventag/app/wallet/WalletManager.kt | 204 +++++++++-- 5 files changed, 622 insertions(+), 204 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index de702e2..4e35fbd 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -984,22 +984,39 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { * AUTO-SWEEP: Automatically consolidates any funds sent to old/exposed addresses * to the current clean address (currentIndex+1) before loading the balance. */ + private val isRefreshing = java.util.concurrent.atomic.AtomicBoolean(false) + fun refreshBalance() { -

If assets were on an old HAS_OUTGOING address (not yet swept), the transfer failed or only RVN moved. Now scans all 0..currentIndex addresses and includes every found asset UTXO in the transaction, each signed with its own address key via the new buildAndSignMultiAddressAssetTransfer. 2. refreshBalance launched healAndSweepTarget for every old address IN PARALLEL, creating dozens of simultaneous ElectrumX TCP connections that triggered server-side connection resets. Replaced with a single sequential sweepOldAddresses call. 3. sweepOldAddressesInternal funded asset-only addresses FROM the current clean address, exposing its private key and defeating post-quantum protection. That early funding block is removed; the correct sacrificial (HAS_OUTGOING) funding path (fundOldAddressForSweep) remains. 4. getLocalBalance returned null for genuinely empty wallets (takeIf > 0), triggering discoverCurrentIndex on every startup even when the index was already correct. Now returns 0.0 for empty and null only on network failure. 5. loadWalletInfo triggered discoverCurrentIndex whenever balance was null, which also fired on transient network errors. Now discovery only runs when currentIndex == 0 (wallet just restored from mnemonic). --- .../main/java/io/raventag/app/MainActivity.kt | 23 +-- .../raventag/app/wallet/RavencoinTxBuilder.kt | 88 ++++++++++ .../io/raventag/app/wallet/WalletManager.kt | 153 ++++++++++-------- 3 files changed, 180 insertions(+), 84 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index 6e6eb85..823e969 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -924,14 +924,12 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { // STEP 2: Background maintenance (does not block the UI). launch(Dispatchers.IO) { - // Auto-discovery: if the initial balance is null (no funds on the known - // address range), the stored index may be too low.

From 765cc9b0e4bea6911094ecf595fddf2ab358b296 Mon Sep 17 00:00:00 2001 From: Alessandro Nocentini Date: Sun, 12 Apr 2026 19:48:11 +0200 Subject: [PATCH 010/181] feat: add portfolio scanning with automatic fund consolidation - Enhanced loadOwnedAssets() to detect funds (RVN + assets) scattered across old addresses - Added consolidateAllFundsToFreshAddress() in WalletManager to move all funds to a virgin address (currentIndex + 1) - Added consolidation banner in WalletScreen UI when funds detected on old addresses - Implemented consolidateFunds() in MainActivity to trigger the consolidation process - Portfolio scan now checks both asset balances and RVN balances in parallel - Consolidation transfers all assets and RVN to a fresh, quantum-safe address and advances the index This solves the issue where the portfolio scan wasn't finding funds on old addresses that needed to be consolidated. --- .../main/java/io/raventag/app/MainActivity.kt | 58 ++++++++-

If that address has never signed an outgoing transaction (public key not yet revealed), currentIndex stays there and sweep is a no-op. Only if the address has HAS_OUTGOING status is currentIndex advanced by one, triggering a sweep to a fresh address.

Address and balance are shown only after the correct blockchain index is resolved. Added restoreError state to surface invalid-mnemonic and network errors inside WalletSetupCard instead of the invisible BalanceCard. Added walletScanningBlockchain string (9 languages) shown below the spinner during blockchain scanning. --- .../main/java/io/raventag/app/MainActivity.kt | 25 ++++++++++++------ .../raventag/app/ui/screens/WalletScreen.kt | 26 ++++++++++++++++++- .../io/raventag/app/ui/theme/AppStrings.kt | 14 +++++++--- 3 files changed, 52 insertions(+), 13 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index b26715f..03b1762 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -175,6 +175,9 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { /** True while mnemonic entropy is being generated (prevents double-click). */ var walletGenerating by mutableStateOf(false) + /** Error from the last failed wallet restore (invalid mnemonic, network failure). */ + var restoreError by mutableStateOf(null) + // ── Issue / revoke / register / transfer state ──────────────────────────── /** Currently active issue/revoke/transfer mode (null = no overlay shown). */ @@ -898,35 +901,40 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { if (walletGenerating) return viewModelScope.launch { walletGenerating = true - // Start with loading state — no 0 balance or empty assets shown - walletInfo = WalletInfo(address = "", balanceRvn = 0.0, isLoading = true) + // Hide any stale wallet UI and clear previous errors during discovery. + // hasWallet stays false until the correct index is found, so address and + // balance are never shown before discovery completes. + hasWallet = false + walletInfo = null + restoreError = null try { val restored = withContext(Dispatchers.Default) { wm.restoreWallet(mnemonic) } if (!restored) { - walletInfo = WalletInfo(address = "", balanceRvn = 0.0, error = "Invalid mnemonic") + restoreError = "Invalid mnemonic" return@launch } - // Discover the correct address index (checks both RVN history AND assets) - // This may take a few seconds — isLoading stays true so user sees progress + // Discover the correct address index on the blockchain. + // isGenerating stays true so WalletSetupCard shows a spinner, not the form. try { wm.discoverCurrentIndex() } catch (_: Exception) { Log.w("MainActivity", "discoverCurrentIndex failed, using index 0") } - hasWallet = true val address = wm.getCurrentAddress() ?: "" - walletInfo = walletInfo?.copy(address = address, isLoading = true, error = null) + walletInfo = WalletInfo(address = address, balanceRvn = 0.0, isLoading = true) + hasWallet = true // Now load balance, assets, and history in parallel loadWalletBalance() loadOwnedAssets() loadTransactionHistory() } catch (e: Throwable) { - walletInfo = WalletInfo(address = "", balanceRvn = 0.0, error = "Restore failed: ${e.message}") + restoreError = "Restore failed: ${e.message}" + walletInfo = null } finally { walletGenerating = false } @@ -2811,6 +2819,7 @@ fun RavenTagApp( walletRole = walletRole, controlKeyValidating = viewModel.controlKeyValidating, controlKeyError = viewModel.controlKeyError, + restoreError = viewModel.restoreError, onGenerateWallet = { controlKey -> if (!io.raventag.app.config.AppConfig.IS_BRAND_APP) { viewModel.generateWallet() diff --git a/android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt b/android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt index 440a19f..59888bf 100644 --- a/android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt +++ b/android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt @@ -80,6 +80,7 @@ fun WalletScreen( walletInfo: WalletInfo?, hasWallet: Boolean, isGenerating: Boolean = false, + restoreError: String?

With 15 addresses with history this drops from 30 sequential calls to one batch (2 TLS connections). Estimated 3-5x speedup on mnemonic import. sendRvnLocal: old-fund discovery now scans only 0..currentIndex-1 (not hardcoded 100) and uses getAddressesWithFunds to pre-filter before fetching full UTXOs. Eliminates 100 sequential TLS calls on every send when currentIndex is low. sweepOldAddressesInternal: converted to suspend fun, replacing runBlocking{delay()} with proper coroutine delay(). Thread is now suspended instead of blocked. loadOwnedAssets: consolidation check for old addresses replaced from two full getTotalAssetBalances+getTotalBalance calls to one lightweight getAddressesWithFunds batch call.

Any Node.js major version upgrade, Alpine Linux base image change, or ARM/x86 cross-compilation will require a native rebuild. A mismatch causes an immediate startup crash. The Dockerfile uses `node:20-alpine`; if the base image is updated to Node 22 without rebuilding, the pre-built addon will refuse to load. +- Files: `backend/package.json` (`"better-sqlite3": "^9.4.3"`), `backend/Dockerfile` +- Mitigation: The multi-stage Dockerfile ensures the addon is built in the same environment it runs in. Keep the `node:20-alpine` pin explicit and bump it intentionally. + +**No `package-lock.json` test coverage:** +- Risk: Backend has no test suite (no Jest, Mocha, or similar in `backend/package.json`). Dependency upgrades (e.g., `axios`, `zod`) are not regression-tested. The `^` version pins in `package.json` allow minor/patch upgrades that could introduce breaking changes silently. +- Files: `backend/package.json` + +**Bouncy Castle included as a compile-time dependency in Android:** +- Risk: `android/app/build.gradle.kts` depends on `bouncy.castle` for AES-CMAC, ECDSA, and BIP32 operations. Bouncy Castle is a large library and has had historical CVEs (mostly in its TLS stack, not AES). The app uses only the crypto primitives, not the TLS stack. No version is pinned in the concern list without checking `libs.versions.toml`. +- Files: `android/app/build.gradle.kts` + +**`axios` v1.6.7 in backend is not the latest patch:** +- Risk: `axios` 1.6.x had a SSRF-related advisory (GHSA-wf5p-g6vw-rhxx) in some configurations. The IPFS fetch code in `backend/src/services/ipfs.ts` uses axios for external network calls. The SSRF mitigation is applied at the application layer (`ipfsUriToHttp`), but upgrading to the latest patch is low-risk. +- Files: `backend/package.json` (`"axios": "^1.6.7"`), `backend/src/services/ipfs.ts` + +--- + +## Operational + +**SQLite hot backup may produce a corrupt file under write load:** +- Risk: The backup container in `docker-compose.yml` (lines 39-54) reads `/data/raventag.db` with `openssl enc` (a raw file copy). SQLite WAL mode does not guarantee a consistent copy of a file read this way while writes are in progress. The result is a backup that may not be a valid SQLite database. +- Files: `docker-compose.yml:39-54` +- Fix approach: Replace the raw file copy with `sqlite3 /data/raventag.db ".backup /backups/raventag_${TIMESTAMP}.db"` (SQLite's online backup API), which is safe under concurrent writes, then encrypt the output. + +**No structured error logging or log aggregation:** +- Problem: All backend errors are logged to stdout with `console.error('[tag]', err)`. There is no structured JSON logging, no log level filtering, and no integration with an external log aggregator. Debugging production issues requires direct access to container logs. +- Files: `backend/src/middleware/logger.ts`, all route files using `console.error` +- Fix approach: Replace `console.error` with a structured logger (e.g., `pino`) that emits JSON with severity, timestamp, request ID, and stack trace. + +**No process-level unhandledRejection handler:** +- Problem: `backend/src/index.ts` does not register a `process.on('unhandledRejection', ...)` handler. An unhandled promise rejection in Node.js 20+ terminates the process. The Express global error handler on line 225 only catches synchronous errors thrown inside route handlers; async errors from outside the request lifecycle (e.g., ElectrumX background operations) are uncaught. +- Files: `backend/src/index.ts` +- Fix: Add `process.on('unhandledRejection', (reason) => console.error('[Fatal]', reason))` at startup. + +**Single Docker container = single point of failure:** +- Problem: The entire backend runs as one Node.js process in one container with a single SQLite file. There is no horizontal scaling path, no read replica, and no failover. A backend restart causes brief downtime for all scan verification requests. +- Files: `docker-compose.yml` +- Impact: Acceptable for an open-source self-hosted protocol, but relevant for brands expecting high availability. + +**No health check on the frontend container:** +- Problem: `docker-compose.yml` defines a `healthcheck` only for the `backend` service. The `frontend` service (if defined) has no health check. The backup container depends on `backend` being healthy, but if the frontend is down the compose stack still reports healthy. +- Files: `docker-compose.yml` + +**`request_logs` IP field stores raw X-Forwarded-For header value:** +- Problem: `backend/src/middleware/logger.ts:37-38` reads the first value from `X-Forwarded-For` to populate the `ip` column. This value is controlled by the client if the server is not behind a trusted reverse proxy. The trust is set globally with `app.set('trust proxy', 1)` (`index.ts:63`), which trusts exactly one proxy hop. If the deployment has zero or more than one proxy hop, the stored IP will be wrong or spoofed. +- Files: `backend/src/middleware/logger.ts:37-38`, `backend/src/index.ts:63` +- Fix: Document the required `trust proxy` setting in `.env.example` and verify against the actual deployment topology. + +--- + +## Data Integrity + +**Soft revocation is per-instance: multi-backend deployments produce inconsistent results:** +- Problem: Revocation state lives entirely in the local SQLite database (`revoked_assets` table). If two instances of the backend are deployed behind a load balancer (or even with a blue-green deploy), a revocation applied to instance A is not visible to instance B until the database is shared or replicated. A scanner hitting the unrevoked instance would see an AUTHENTIC result for a revoked asset. +- Files: `backend/src/middleware/cache.ts:74-82`, `backend/src/routes/brand.ts:54-70` +- Fix approach: For multi-instance deployments, mount the same SQLite file via a shared NFS/EFS volume, or migrate to PostgreSQL. Document this single-instance constraint in the deployment guide. + +**`issued_at` field in `asset_emissions` is user-supplied:** +- Problem: `backend/src/routes/registry.ts:140` uses `issued_at || new Date().toISOString()`. The client can supply any `issued_at` value, including timestamps in the past or future, without validation. The field is used for ordering in the public emissions list. +- Files: `backend/src/routes/registry.ts:140` +- Fix: Ignore the client-supplied `issued_at` and always use `new Date().toISOString()` server-side, or validate that the value is a well-formed ISO 8601 date within an acceptable window. + +**Asset emission notifications auto-register brands without verification:** +- Problem: `backend/src/routes/registry.ts:151-157` auto-registers the root part of a notified asset name as a brand in `brand_registry` without any ownership verification. Any caller who knows a valid `txid` for a root asset can cause that asset name to appear in the public brand directory. +- Files: `backend/src/routes/registry.ts:151-157` +- Impact: The public brand list can be polluted with brand names that are not operated by the notifier. +- Fix approach: Require the brand to be explicitly registered via the admin-protected `POST /api/registry/register` endpoint, and remove the auto-registration from the notify path. + +--- + +*Concerns audit: 2026-04-13* diff --git a/.planning/codebase/CONVENTIONS.md b/.planning/codebase/CONVENTIONS.md new file mode 100644 index 0000000..328cc54 --- /dev/null +++ b/.planning/codebase/CONVENTIONS.md @@ -0,0 +1,139 @@ +# Coding Conventions + +**Analysis Date:** 2026-04-13 + +## Naming Patterns + +**Files:** +- TypeScript backend: `camelCase.ts` (e.g., `ntag424.ts`, `ravencoin.ts`, `cache.ts`) +- TypeScript frontend components: `PascalCase.tsx` (e.g., `CookieBanner.tsx`, `LanguageSelector.tsx`) +- Next.js pages: `page.tsx` in directory-named routes (App Router pattern) +- Kotlin Android: `PascalCase.kt` (e.g., `SunVerifier.kt`, `WalletManager.kt`, `NfcReader.kt`) +- Test files (Android): `PascalCaseTest.kt` co-located under `src/test/` mirroring `src/main/` package path + +**Functions:** +- TypeScript: `camelCase` for all exported and internal functions (`computeNfcPubId`, `verifySunMessage`, `requireAdminKey`, `isAssetRevoked`) +- Kotlin: `camelCase` methods inside `object` singletons or classes; top-level helpers also `camelCase` +- React components: `PascalCase` default exports matching the filename (`export default function HomePage()`, `export default function AdminPage()`) + +**Variables:** +- TypeScript/JS: `camelCase` (`tagUid`, `sdmMacKey`, `adminKey`, `sessionMacKey`) +- Kotlin: `camelCase` (`sdmEncKey`, `sdmMacKey`, `tagUid`, `testPrivKey`) +- Constants: `SCREAMING_SNAKE_CASE` for module-level config values (`BURN_ROOT_SAT`, `DB_PATH`, `API`, `LIMIT`) + +**Types / Interfaces:** +- TypeScript: `PascalCase` interfaces and type aliases (`SunVerifyResult`, `RegisteredBrand`, `RevokedAsset`) +- Exported schemas from Zod: `camelCaseSchema` naming (`assetNameSchema`, `sunVerifyRequestSchema`) +- Inferred TypeScript types from Zod: `PascalCase` (`type AssetName = z.infer`) +- Kotlin data classes: `PascalCase` (`SunVerifyResult`, `Utxo`) + +## Code Style + +**Formatting:** +- No Prettier config present; formatting is implicit from TypeScript compiler strictness +- Indentation: 2 spaces in TypeScript/TSX throughout backend and frontend +- Indentation: 4 spaces in Kotlin +- Single quotes for string literals in TypeScript; double quotes in Kotlin and JSX attributes +- Trailing commas used in multi-line TypeScript object/function argument lists + +**Linting:** +- Backend: ESLint via `"lint": "eslint src --ext .ts"` in `backend/package.json`; no config file detected (uses defaults) +- Frontend: Next.js built-in ESLint via `"lint": "next lint"` +- TypeScript strict mode enabled in `backend/tsconfig.json` (`"strict": true`) +- `esModuleInterop: true`, `forceConsistentCasingInFileNames: true`, `skipLibCheck: true` + +## Import Organization + +**TypeScript backend order (observed pattern):** +1.

pattern:** +- `fetch` calls are wrapped in `.then(r => r.ok ? r.json() : null).catch(() => {})` for non-critical UI data +- State for user-facing messages uses `{ ok: boolean; text: string } | null`

@Test(expected = IllegalArgumentException::class) + fun `buildAndSign with corrupted recipient address checksum throws`() { ... } +} +``` + +**Key patterns:** +- Test method names use backtick syntax for readable English descriptions +- Tests are grouped by behavior topic with inline section comments (`// ── base58Decode checksum fix tests`) +- No `@Before`/`@After` setup; each test is self-contained +- Lazy properties (`by lazy`) used for expensive shared test data that depends on other lazy values + +## Mocking + +**Framework:** None (no Mockito or MockK dependency detected) + +**Patterns:** +- Tests use independently implemented reference functions (not the class under test) to generate expected values and valid test vectors +- Test vectors are computed from first principles (standard Java crypto APIs + BouncyCastle) so the test verifies correctness against an independent implementation, not against itself + +```kotlin +// Pattern: independent reference implementation to build test vectors +private fun buildSunVector( + sdmEncKey: ByteArray, + sdmMacKey: ByteArray, + uid: ByteArray, + counter: Int +): Pair { + // Uses Cipher.getInstance("AES/CBC/NoPadding") directly, not SunVerifier + val eHex = aesCbcEncrypt(sdmEncKey, plaintext).joinToString("") { "%02x".format(it) } + ... + return eHex to mHex +} +``` + +**What to Mock:** +- Not applicable; tests use real crypto implementations to verify cryptographic correctness + +**What NOT to Mock:** +- Crypto primitives: always use real AES/CMAC for test vector generation; mocking would defeat the purpose + +## Fixtures and Factories + +**Test Data:** +```kotlin +// Fixed scalar-1 private key (always valid on secp256k1) +private val testPrivKey = ByteArray(31) { 0 } + byteArrayOf(1) +private val testPubKey by lazy { pubKeyFromPrivKey(testPrivKey) } +private val senderAddress by lazy { testAddress(testPrivKey) } +private val senderScript by

functions are private members of the test class; no shared fixture files + +## Coverage + +**Requirements:** None enforced; no JaCoCo or coverage threshold configured + +**View Coverage:** +```bash +cd android +./gradlew test jacocoTestReport # Only if JaCoCo plugin is added +``` + +## Test Types + +**Unit Tests:** +- Scope: individual `object` singletons (`SunVerifier`, `RavencoinTxBuilder`) in isolation +- Approach: provide controlled inputs, assert on return values and thrown exceptions +- Location: `android/app/src/test/` + +**Integration Tests:** +- Not present + +**E2E / Instrumented Tests:** +- Dependencies declared but no test files written; Android device required +- Location would be: `android/app/src/androidTest/` + +**Backend Tests:** +- Not present; no Jest/Vitest/Mocha configuration found in `backend/` + +**Frontend Tests:** +- Not present; no test configuration found in `frontend/` + +## Common Patterns + +**Testing a cryptographic happy path:** +```kotlin +@Test +fun `verify with valid SUN vector returns true with correct uid and counter`() { + val (eHex, mHex) = buildSunVector(sdmEncKey, sdmMacKey, uid, counter) + val result = SunVerifier.verify(eHex, mHex,

uid.contentEquals(result.tagUid!!)) + assertEquals("Counter must match", counter, result.counter) + assertNull("No error on success", result.error) +} +``` + +**Testing expected exceptions:** +```kotlin +@Test(expected = IllegalArgumentException::class) +fun `buildAndSign with corrupted recipient address checksum throws`() { + // Corrupt one character of the Base58Check address + val badAddress = validAddress.dropLast(1) + corruptChar + RavencoinTxBuilder.buildAndSign(utxos, toAddress = badAddress, ...) +} +``` + +**Testing failure / invalid input:** +```kotlin +@Test +fun `verify with corrupted MAC returns invalid`() { + val (eHex, mHex) = buildSunVector(...) + val badMHex = mHex.dropLast(1) + if (mHex.last() == 'f') '0' else 'f' + val result = SunVerifier.verify(eHex, badMHex, sdmEncKey, sdmMacKey) + + assertFalse("Corrupted MAC must fail verification", result.valid) + assertNotNull("Error message must be set", result.error) +} +``` + +**Testing raw transaction bytes (structural tests):** +```kotlin +@Test +fun `buildAndSign transaction has correct version bytes`() { + val result = RavencoinTxBuilder.buildAndSign(...) + assertTrue("tx must start with version 2 (02000000)", result.hex.startsWith("02000000")) +} + +@Test +fun `txid is double-sha256 of raw tx reversed`() { + val rawBytes = result.hex.chunked(2).map { it.toInt(16).toByte() }.toByteArray() +

AdminKeyStorage Class (New) +- **Location**: `android/app/src/main/java/io/raventag/app/security/AdminKeyStorage.kt` +- **Purpose**: Secure wrapper for admin key using EncryptedSharedPreferences +- **Encryption**: AES-256-GCM via Android Keystore +- **API**: `getAdminKey()`, `setAdminKey()`, `hasAdminKey()`, `clearAdminKey()` +- **Security**: Prevents extraction from APK (unlike BuildConfig which is extractable via strings/JADX) + +### 2. AssetManager Migration +- **Constructor change**: Now accepts `Context` and `AdminKeyStorage` instead of `adminKey: String` +- **Admin key access**: Uses computed property that reads from encrypted storage +- **Error handling**: Throws `IllegalStateException` if admin key not configured (fail-safe) +- **Security**: No longer relies on hardcoded or BuildConfig admin key + +### 3. MainViewModel Validation +- **Added**: `validateAdminKey()` suspend function using OkHttp +- **Endpoint**: `/api/admin/validate-key` (or existing admin endpoints) +- **Status tracking**: Updates `adminKeyStatus` (UNKNOWN, CHECKING, VALID, INVALID, WRONG_TYPE) +- **Existing**: `AdminKeyStatus` enum class and `adminKeyStatus` state variable already existed + +### 4. Settings Screen UI +- **New section**: Admin API Key input after Kubo node URL, before Language picker +- **Components**: `SectionLabelWithAdminStatus`, `SettingsTextField` (password field), `SettingsSaveButton` +- **Validation**: Status chip shows key verification result (checking, valid, invalid, wrong type) +- **Security**: Password field masks input to prevent shoulder surfing + +### 5. MainActivity Wiring +- **AdminKeyStorage**: Created as property, initialized before AssetManager +- **AssetManager**: Instantiated with `AdminKeyStorage` instead of `BuildConfig.ADMIN_KEY` +- **SettingsScreen**: Added `currentAdminKey`, `onAdminKeySave`, `adminKeyStatus` parameters +- **Save flow**: Validates key against backend before persisting to encrypted storage +- **Auto-check**: LaunchedEffect checks admin key status when server is online + +### 6. BuildConfig Cleanup +- **Removed**: `buildConfigField("String", "ADMIN_KEY", "\"\"")` line from `build.gradle.kts` +- **Security**: Admin key no longer compiled into APK (prevents static analysis extraction) + +## Security Improvements + +1. **APK Extraction Prevention**: Admin key no longer in BuildConfig (not extractable via strings/JADX) +2. **Device Storage Encryption**: AES-256-GCM encryption via Android Keystore (hardware-backed when available) +3. **Input Validation**: Key validated against backend before persistence (prevents invalid key storage) +4. **Shoulder Surfing Prevention**: Password field masks input (dots/asterisks) +5. **Fail-Safe Behavior**: AssetManager throws exception if admin key missing (prevents unauthorized operations) + +## Backward Compatibility + +- **Breaking Change**: Existing installations will need to re-enter admin key in Settings +- **Migration Path**: Admin key stored in old securePrefs location not automatically migrated (manual re-entry required) +- **Rationale**: Old storage used shared key file; new storage uses dedicated encrypted prefs file for better isolation + +## Testing Notes + +Manual verification required (see checkpoint in plan): +1. Build Android app: `./gradlew assembleBrandRelease` +2. Install APK on device/emulator +3. Navigate to Settings screen +4. Enter admin key in "Admin API Key" section +5.

Overall code quality is good with consistent patterns and thorough documentation, but several security-hardening opportunities remain. + +## Critical Issues + +### CR-01: Hardcoded Backend URL Exposes Attack Surface + +**File:** `android/app/build.gradle.kts:35-41` +**Issue:** Backend API URL is hardcoded in BuildConfig, which is extractable from the compiled APK via static analysis tools (strings, JADX). This exposes the production backend URL and allows attackers to: +1. Directly target the backend without going through the app +2. Potentially discover API endpoints through enumeration +3. Bypass any client-side validation or rate limiting + +**Fix:** +```kotlin +// Remove hardcoded URL from BuildConfig +// buildConfigField("String", "API_BASE_URL", "\"https://api.raventag.com\"") + +// Instead, load from environment or secure storage at runtime +// In MainActivity.kt or MainViewModel.kt: +private val prefs = context.getSharedPreferences("raventag_app", Context.MODE_PRIVATE) +var currentVerifyUrl by mutableStateOf( + prefs.getString("api_base_url", "https://api.raventag.com") ?: "https://api.raventag.com" +) +``` + +**Rationale:** The SettingsScreen already allows users to configure the backend URL. Remove the hardcoded default and require explicit configuration or use a more obfuscated approach (e.g., encrypted storage, runtime assembly). + +### CR-02: JSON Parsing Without Validation in AssetManager + +**File:** `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt:249-257` +**Issue:** The `adminRequest()` method parses JSON responses without validating the structure, potentially allowing: +1. Malicious server responses to cause crashes or unexpected behavior +2. Injection of unexpected data types (e.g., arrays instead of objects) +3. Security vulnerabilities if response data is used in sensitive operations + +**Fix:** +```kotlin +private fun adminRequest(method: String, path: String, body: Any? = null): JsonObject { + val rb = body?.let { gson.toJson(it).toRequestBody(json) } + val request = Request.Builder() + .url("$apiBaseUrl$path") + .header("X-Admin-Key", adminKey) + .apply { + when (method) { + "POST" -> post(rb ?: "{}".toRequestBody(json)) + "DELETE" -> delete(rb) + else -> get() + } + } + .build() + + val response = http.newCall(request).execute() + val bodyStr = response.body?.string() ?: "{}" + + // Validate response is JSON before parsing + val obj = try { + gson.fromJson(bodyStr, JsonObject::class.java) + } catch (e: Exception) { + throw IOException("Invalid JSON response from server") + } + + // Validate expected structure based on endpoint + if (!obj.has("success") || obj["success"] == null) { + throw IOException("Missing 'success' field in response") + } + + if (!response.isSuccessful) { + val errMsg = obj["error"]?.asString ?: "HTTP ${response.code}" + throw IOException(errMsg) + } + return obj +} +``` + +**Rationale:** Add structural validation to ensure responses match expected format before processing. This prevents crashes and potential security issues from malformed or malicious server responses. + +## Warnings + +### WR-01: Missing Null Check in TofuFingerprintDao + +**File:** `android/app/src/main/java/io/raventag/app/security/TofuFingerprintDao.kt:72-84` +**Issue:** `getFingerprint()` assumes `db` is non-null due to the early return, but if `db` becomes null after the check (unlikely but possible in multi-threaded scenarios), it could crash. + +**Fix:** +```kotlin +fun getFingerprint(host: String): String? { + val db = db ?: return null + return try { + val cursor = db.query( + CERT_TABLE, + arrayOf("fingerprint"), + "host = ?", + arrayOf(host), + null, null, null + ) + cursor.use { + if (it.moveToFirst()) it.getString(0) else null + } + } catch (e: Exception) { + Log.e(TAG, "Failed to get fingerprint for $host", e) + null + } +} +``` + +### WR-02: Unvalidated User Input in AssetManager Admin Key + +**File:** `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt:190-192` +**Issue:** Admin key is retrieved from encrypted storage without validation that it's non-empty and properly formatted.

Integration with background send execution + └── TransferScreen.kt # MODIFY: Integration with background send execution +``` + +### Pattern 1: OkHttp Async Wrapper for Suspend Functions +**What:** Create suspend wrapper functions that convert blocking OkHttp execute() calls to suspendCancellableCoroutine, allowing them to be called from coroutine contexts without blocking the dispatcher thread. + +**When to use:** Any network operation that currently uses OkHttp's blocking execute() method and needs to be called from suspend functions in ViewModels or UI coroutines. + +**Example:** +```kotlin +// Source: Codebase analysis (RpcClient.kt:116, AssetManager.kt:214) [VERIFIED: codebase analysis] +// Pattern to add to a shared utility object or as extension functions + +import okhttp3.Call +import okhttp3.Response +import kotlinx.coroutines.suspendCancellableCoroutine +import java.io.IOException + +// Extension function for OkHttp Call to make it suspend +suspend fun Call.executeSuspend(): Response = suspendCancellableCoroutine { continuation -> + enqueue(object : Callback { + override fun onFailure(call: Call, e: IOException) { + continuation.resumeWithException(e) + } + + override fun onResponse(call: Call, response: Response) { + continuation.resume(response) + } + }) +} + +// Usage in RpcClient (replace blocking execute()) +suspend fun rpcCallSuspend(method: String, params: List = emptyList()): JsonObject = withContext(Dispatchers.IO) { + val payload = RpcPayload(method = method, params = params) + val body = gson.toJson(payload).toRequestBody(json) + val request = Request.Builder() + .url(rpcUrl) + .post(body) + .build() + + // BEFORE (blocking): + // val response = http.newCall(request).execute() + + // AFTER (suspend): + val response = http.newCall(request).executeSuspend() + + if (!response.isSuccessful) { + throw IOException("RPC HTTP error: ${response.code}") + } + + val responseJson = gson.fromJson(response.body?.string(), JsonObject::class.java) + val error = responseJson["error"] + if (error != null && !error.isJsonNull) { + val errObj = error.asJsonObject + throw IOException("RPC error ${errObj["code"]?.asInt}: ${errObj["message"]?.asString}") + } + + return responseJson +} +``` + +### Pattern 2: Parallel Wallet Restore with async/awaitAll +**What:** Launch multiple async operations within coroutineScope and wait for all to complete, reducing sequential blocking time. + +**When to use:** WalletManager operations that fetch data from multiple independent sources (UTXOs, balances, history, status). + +**Example:** +```kotlin +// Source: Existing WalletManager.kt pattern (lines 365-441) [VERIFIED: codebase analysis] +// Modification to discoverCurrentIndex() for parallel loading + +suspend fun discoverCurrentIndex(): Int = withContext(Dispatchers.IO) { + val node = RavencoinPublicNode(context) + val currentStoredIndex = getCurrentAddressIndex() + val searchLimit = maxOf(currentStoredIndex + 50, 100) + + android.util.Log.i("WalletManager", "discoverCurrentIndex: Scanning 0..$searchLimit for RVN and assets") + + val batchMap = getAddressBatch(0, 0 until searchLimit) + if (batchMap.isEmpty()) return@withContext currentStoredIndex + + // BEFORE (sequential): + // val addrList = batchMap.values.toList() + // val statusMap = node.getAddressStatusBatch(addrList) + // ... more sequential calls ... + + // AFTER (parallel): + val addrList = batchMap.values.toList() + + return coroutineScope { + // Phase 1: Parallel status check + val statusDeferred = async { node.getAddressStatusBatch(addrList) } + + // Phase 2: Parallel funds check (depends on Phase 1) + val statusMap = statusDeferred.await() + val addressesWithHistory = (0 until searchLimit).mapNotNull { i -> + val addr = batchMap[i] ?: return@mapNotNull null + val status = statusMap[addr] ?: AddressStatus.NO_HISTORY + if (status != AddressStatus.NO_HISTORY) i to addr else null + } + + val withFundsDeferred = async { + val historyAddrList = addressesWithHistory.map { it.second } + node.getAddressesWithFunds(historyAddrList) + } + + // Await both phases in parallel + val withFunds = withFundsDeferred.await() + + // ... continue with parallel results for index determination + + val finalResult = maxOf( + when { + lastWithFunds >= 0 -> { + val fundsAddr = batchMap[lastWithFunds] + val fundsStatus = fundsAddr?.let { statusMap[it] } + ?: AddressStatus.NO_HISTORY + if (fundsStatus == AddressStatus.HAS_OUTGOING) { + android.util.Log.i("WalletManager", "discoverCurrentIndex: index $lastWithFunds key exposed, using ${lastWithFunds + 1}") + lastWithFunds + 1 + } else { + android.util.Log.i("WalletManager", "discoverCurrentIndex: index $lastWithFunds has funds, key safe, staying there") + lastWithFunds + } + } + lastUsed >= 0 -> lastUsed + 1 + else -> 0 + }, + currentStoredIndex + ) + setCurrentAddressIndex(finalResult) + android.util.Log.i("WalletManager", "Discover: current index = $finalResult (lastUsed=$lastUsed, lastWithFunds=$lastWithFunds)") + finalResult + } +} +``` + +### Pattern 3: Send Operation with Android Notifications +**What:** Use Android NotificationManager to show progress for long-running send operations, allowing users to dismiss the app while transaction broadcasts and confirms. + +**When to use:** Any blockchain transaction (send RVN, send asset, issue asset) that may take seconds to broadcast and multiple blocks to confirm. + +**Example:** +```kotlin +// Source: Existing NotificationHelper.kt pattern + CONTEXT.md D-03 through D-06 [VERIFIED: codebase analysis] +// NEW class for transaction progress notifications + +package io.raventag.app.worker + +import android.app.NotificationChannel +import android.app.NotificationManager +import android.app.PendingIntent +import android.content.Context +import android.content.Intent +import android.os.Build +import androidx.core.app.NotificationCompat +import androidx.core.app.NotificationManagerCompat +import io.raventag.app.R + +object TransactionNotificationHelper { + + private const val CHANNEL_ID = "transaction_progress" + private const val NOTIFICATION_ID = 2000 + + /** + * Create notification channel for transaction progress. + * Must be called before any notification is posted (Android 8+). + */ + fun createChannel(context: Context) { + if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { + val channel = NotificationChannel( + CHANNEL_ID, + "Transaction Progress", + NotificationManager.IMPORTANCE_LOW + ).apply { + description = "Blockchain transaction broadcast and confirmation progress" + setShowBadge(false) + enableVibration(false) + } + context.getSystemService(NotificationManager::class.java) + .createNotificationChannel(channel) + } + } + + /** + * Show or update transaction

confirming, completed, failed). + * @param txid Transaction ID (null if not yet broadcast). + */ + fun updateProgress(context: Context, stage: TransactionStage, txid: String? = null) { + val (title, message) = when (stage) { + TransactionStage.BROADCASTING -> "Broadcasting..." to "Transaction is being broadcast to network" + TransactionStage.CONFIRMING -> "Confirming (1/N)" to "Waiting for block confirmation" + TransactionStage.COMPLETED -> "Completed" to "Transaction confirmed on blockchain" + TransactionStage.FAILED -> "Failed" to "Transaction failed" + } + + val notification = NotificationCompat.Builder(context, CHANNEL_ID) + .setSmallIcon(R.mipmap.ic_launcher) + .setContentTitle(title) + .setContentText(message) + .setOngoing(stage == TransactionStage.BROADCASTING || stage == TransactionStage.CONFIRMING) + .setAutoCancel(stage == TransactionStage.COMPLETED || stage == TransactionStage.FAILED) + .build() + + NotificationManagerCompat.from(context).notify(NOTIFICATION_ID, notification) + } + + /** + * Create pending intent for transaction details screen. + * Tapping notification opens app to specific transaction details. + */ + fun createDetailsIntent(context: Context, txid: String): PendingIntent { + val intent = Intent(context, MainActivity::class.java).apply { + action = "OPEN_TX_DETAILS" + putExtra("txid", txid) + flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK + } + return PendingIntent.getActivity( + context, + 0, + intent, + PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE + ) + } + + enum class TransactionStage { + BROADCASTING, CONFIRMING, COMPLETED, FAILED + } +} +``` + +### Pattern 4: Exponential Backoff Retry Logic +**What:** Implement retry logic with exponential delay between attempts for transient network failures. + +**When to use:** Network operations that may fail temporarily (wallet restore, send operations). + +**Example:** +```kotlin +// Source: CONTEXT.md D-02 and D-06 decisions [VERIFIED: user decisions] +// Retry utility for transient failures + +suspend fun retryWithBackoff( + maxAttempts: Int = 5, + initialDelayMs: Long = 1000L, + backoffMultiplier: Double = 2.0, + block: suspend () -> T +): T { + var lastException: Exception? = null + var currentDelay = initialDelayMs + + repeat(maxAttempts) { attempt -> + try { + return block() + } catch (e: Exception) { + lastException = e + // Check if error is transient (network timeout, temporary failure) + val isTransient = isTransientError(e) + + if (attempt < maxAttempts - 1 && isTransient) { + android.util.Log.w("Retry", "Attempt ${attempt + 1} failed, retrying in ${currentDelay}ms: ${e.message}") + kotlinx.coroutines.delay(currentDelay) + currentDelay = (currentDelay * backoffMultiplier).toLong() + } else { + // Last attempt or non-transient error: throw immediately + throw e + } + } + } + // Should not reach here, but handle edge case + throw lastException ?: IllegalStateException("Retry logic failed") +} + +private fun isTransientError(e: Exception): Boolean { + val message = e.message?.lowercase() ?: return false + return message.contains("timeout") || + message.contains("connection") || + message.contains("network") || + message.contains("temporary") || + e is java.net.SocketTimeoutException || + e is java.net.UnknownHostException +} + +// Usage in wallet restore: +suspend fun discoverCurrentIndex(): Int = retryWithBackoff { + // ... existing logic +} + +// Usage in send operations: +suspend fun sendRvnLocal(toAddress: String, amountRvn: Double): String = retryWithBackoff { + // ... existing logic +} +``` + +### Anti-Patterns to Avoid +- **Calling OkHttp execute() from main thread**: Blocks UI thread, causes ANR. Always wrap in withContext(Dispatchers.IO) or use suspend wrapper. +- **Sequential independent network calls**: Running independent operations one after another instead of in parallel wastes time. Use async/awaitAll for concurrent fetching. +- **Ignoring coroutine cancellation**: Long-running operations that don't check coroutineScope.isActive may waste resources after user navigates away. Add cancellation checks in loops. +- **Using Thread.sleep() in coroutines**: Blocking sleep blocks dispatcher thread. Use kotlinx.coroutines.delay() instead for cooperative cancellation. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|----------|---------------|-------------|-----| +| OkHttp async wrapper | Manual threading, ExecutorService | Kotlin suspendCancellableCoroutine integrates with coroutines, supports cancellation, structured concurrency | +| Custom retry logic | Linear retry, fixed delays | Exponential backoff with jitter handles network congestion better, reduces thundering herd | +| Sequential wallet operations | Sequential calls | async/awaitAll in coroutineScope provides parallelism without thread management complexity | +| Manual notification building | Builder pattern each time | NotificationCompat.Builder is standard Android API, no need for custom notification system | + +**Key insight:** Kotlin coroutines provide structured concurrency that integrates with Android lifecycle (viewModelScope, rememberCoroutineScope). Converting blocking calls to suspend functions enables proper dispatcher switching (Dispatchers.IO) and cooperative cancellation, preventing ANRs while maintaining code simplicity. + +## Runtime State Inventory + +> Omitted - this is a performance optimization phase, not a rename/refactor/migration phase. No stored data, service configs, or OS-registered state needs migration. + +## Common Pitfalls + +### Pitfall 1: Blocking Main Thread with Network Calls +**What goes wrong:** Calling OkHttp execute() directly from Composable UI or ViewModel without coroutine context blocks the main thread, causing frame drops and potential ANR (Application Not Responding) errors. + +**Why it happens:** OkHttp's execute() is a synchronous blocking method. When called from main thread dispatcher, it blocks all UI rendering until network response arrives. + +**How to avoid:** +- Always call network operations from suspend functions wrapped in withContext(Dispatchers.IO) +- Use viewModelScope.launch() for fire-and-forget operations in ViewModels +- Use rememberCoroutineScope().launch() for one-shot operations in Composables +- Convert existing blocking execute() calls to suspend wrappers (suspendCancellableCoroutine) + +**Warning signs:** UI freezes during wallet refresh, send buttons unresponsive, janky animations, "Application Not Responding" dialogs on device. + +### Pitfall 2: Sequential Wallet Restore on Large Wallets +**What goes wrong:** When a wallet has many addresses (e.g., index > 50), sequential fetching of UTXOs, balances, and status for each address takes many seconds, causing UI freeze during restore. + +**Why it happens:** Each address discovery involves multiple network round trips (status check, balance query, UTXO fetch). Doing these sequentially multiplies the total time. + +**How to avoid:** +- Use coroutineScope with async() for independent operations +- Group dependent operations properly (await dependencies before using results) +- Fetch data in batches where the ElectrumX server supports it (already implemented in getAddressStatusBatch) +- Add loading indicator during restore to set user expectations + +**Warning signs:** Restore takes >10 seconds for wallets with ~20 addresses, progress UI not updating, user force-quits app during restore. + +### Pitfall 3: Send Operation Without Feedback During Confirmation +**What goes wrong:** Users tap "Send", see a loading spinner, and nothing happens for 10-60 seconds while transaction broadcasts and confirms. They may tap back or kill the app, losing confidence that transaction was sent. + +**Why it happens:** Current implementation uses withContext(Dispatchers.IO) to run send operations but has no persistent feedback mechanism visible when app is in background. + +**How to avoid:** +- Create dedicated notification channel for transaction progress +- Show ongoing notification while broadcasting/confirming +- Update notification with stage changes (broadcasting -> confirming -> completed) +- Allow tapping notification to view transaction details (D-04) +- Show error notification with retry action on failure (D-06) + +**Warning signs:** Users report "I don't know if my send worked", close app during send, send button stays disabled indefinitely. + +### Pitfall 4: Ignoring Coroutine Cancellation +**What goes wrong:** User navigates away from a screen but the background coroutine continues running, wasting resources and potentially causing race conditions when they return. + +**Why it happens:** Long-running loops and network calls don't check coroutineScope.isActive or use withTimeout, continuing work after the UI has been abandoned. + +**How to avoid:** +- Use coroutineScope for structured concurrency (automatically cancelled when scope cancelled) +- Check isActive in loops: `if (!isActive) break` or `if (!isActive) continue` +- Use try/finally to clean up resources even when cancelled +- Use withTimeout() for operations that should give up after a deadline + +**Warning signs:** Logs show operations continuing after screen dismiss, duplicate network calls, "Scope cancelled but work still running" errors. + +### Pitfall 5: IPFS Upload Blocking Issue Asset Flow +**What goes wrong:** When issuing an asset with IPFS metadata, the IPFS upload (via KuboUploader or PinataUploader) blocks the issue flow. If the upload takes >5 seconds, the UI feels frozen. + +**Why it happens:** KuboUploader.uploadFile() and PinataUploader.uploadFile() use blocking OkHttp execute() directly. Called synchronously from issue flow without proper async wrapping. + +**How to avoid:** +- Convert KuboUploader and PinataUploader to use suspend wrapper functions +- Wrap IPFS upload calls in withContext(Dispatchers.IO) +- Show progress indicator during upload +- Consider using foreground service for very large file uploads (not needed for metadata JSON) + +**Warning signs:** Issue asset dialog freezes after clicking confirm, no feedback for 10+ seconds, user taps back and retry causes duplicate issues. + +## Code Examples + +Verified patterns from official sources: + +### OkHttp Suspend Wrapper +```kotlin +// Source: Codebase analysis (RpcClient.kt:116, AssetManager.kt:214) [VERIFIED: codebase analysis] +// Extension function to convert blocking Call.execute() to suspend function + +import okhttp3.Call +import okhttp3.Response +import kotlinx.coroutines.suspendCancellableCoroutine + +suspend fun T.executeSuspend(): Response = suspendCancellableCoroutine { continuation -> + enqueue(object : Callback { + override fun onFailure(call: Call, e: IOException) { + continuation.resumeWithException(e) + } + + override fun onResponse(call: Call, response: Response) { + continuation.resume(response) + } + }) +} +``` + +### Parallel Address Discovery +```kotlin +// Source: Existing WalletManager.kt pattern (lines 365-441) [VERIFIED: codebase analysis] +// Modified discoverCurrentIndex with parallel operations + +suspend fun discoverCurrentIndex(): Int = withContext(Dispatchers.IO) { + val node = RavencoinPublicNode(context) + val currentStoredIndex = getCurrentAddressIndex() + val searchLimit = maxOf(currentStoredIndex + 50, 100) + + val batchMap = getAddressBatch(0, 0 until searchLimit) + if (batchMap.isEmpty()) return@withContext currentStoredIndex + + val addrList = batchMap.values.toList() + + return coroutineScope { + // Launch status check in parallel with future operations + val statusDeferred = async { + node.getAddressStatusBatch(addrList) + } + + val statusMap = statusDeferred.await() + + // Continue with parallel address scanning... + var lastUsed = -1 + for (i in 0 until searchLimit) { + val addr = batchMap[i] ?: continue + val status = statusMap[addr] ?: AddressStatus.NO_HISTORY + if (status != AddressStatus.NO_HISTORY) { + lastUsed = i + } + } + + // Parallel funds check for addresses with history + val addressesWithHistory = (0 until searchLimit).mapNotNull { i -> + val addr = batchMap[i] ?: return@mapNotNull null + val status = statusMap[addr] ?: AddressStatus.NO_HISTORY + if (status != AddressStatus.NO_HISTORY) i to addr else null + } + + val withFunds = try { + node.getAddressesWithFunds(addressesWithHistory.map { it.second }) + } catch (_: Exception) { emptySet() } + + var lastWithFunds = -1 + for ((i, addr) in addressesWithHistory) { + if (addr in withFunds) { + lastWithFunds = maxOf(lastWithFunds, i) + } + } + + val finalResult = maxOf( + when { + lastWithFunds >= 0 -> { + val fundsAddr = batchMap[lastWithFunds] + val fundsStatus = fundsAddr?.let { statusMap[it] } + ?: AddressStatus.NO_HISTORY + if (fundsStatus == AddressStatus.HAS_OUTGOING) { + lastWithFunds + 1 + } else { + lastWithFunds + } + } + lastUsed >= 0 -> lastUsed + 1 + else -> 0 + }, + currentStoredIndex + ) + setCurrentAddressIndex(finalResult) + finalResult + } +} +``` + +### Exponential Backoff Retry +```kotlin +// Source: CONTEXT.md D-02, D-06 decisions [VERIFIED: user decisions] + +suspend fun retryWithBackoff( + maxAttempts: Int = 5, + block: suspend () -> T +): T { + var lastException: Exception? = null + var delayMs = 1000L + val multiplier = 2.0 + + repeat(maxAttempts) { attempt -> + try { + return block() + } catch (e: Exception) { + lastException = e + val isTransient = when (e) { + is java.net.SocketTimeoutException -> true + is java.net.UnknownHostException -> true + is java.io.IOException -> e.message?.contains("timeout") == true + else -> false + } + + if (attempt < maxAttempts -

User can navigate back or dismiss app. + - **What's unclear:** Should the send operation continue in background and show notification on completion, or should it be cancelled? CONTEXT.md D-03 suggests "user can dismiss the app while transaction broadcasts", implying continuation. + - **Recommendation:** Continue send operation in background (use WorkManager or foreground service) and show final notification with txid. Add cancellation option in notification if user wants to abort. + +2. **Should IPFS upload errors be retried automatically?** + - **What we know:** CONTEXT.md specifies retry for wallet restore and send operations (D-02, D-06) but not explicitly for IPFS uploads. + - **What's unclear:** Should IPFS upload failures (KuboUploader, PinataUploader) retry with exponential backoff, or fail immediately to user? + - **Recommendation:** Apply same retry policy (5 attempts, 2x backoff) to IPFS uploads for consistency. Treat 4xx/5xx errors as fatal, network errors as retryable. + +3. **What is the target notification style and user interaction?** + - **What we know:** NotificationHelper uses basic notification style with small icon, title, and text. CONTEXT.md D-03 through D-06 specify multiple notifications during lifecycle. + - **What's unclear:** Should notifications use progress bar (setProgress()), big text style, or rich media? Should tapping notification open MainActivity or a dedicated transaction history screen? + - **Recommendation:** Use ongoing notification style for broadcast/confirming stages. Tap opens MainActivity with transaction details intent. D-04 specifies "transaction details screen (not main wallet)" but existing codebase doesn't have dedicated transaction details screen—implement or open Wallet screen with tx highlighted. + +4. **Should confirmation dialog show network fee estimate before user confirms?** + - **What we know:** CONTEXT.md D-07 specifies "confirmation dialog displays: amount, recipient address, and network fee." + - **What's unclear:** Should fee be fetched before showing dialog (adding delay) or estimated and shown in dialog? + - **Recommendation:** Fetch fee estimate in parallel with balance check. Show fee in confirmation dialog. If fee fetch fails, show warning but allow proceed with estimated fee. + +5. **How should loading UI patterns be standardized across the app?** + - **What we know:** SendRvnScreen uses CircularProgressIndicator in button when isLoading=true. TransferScreen has similar pattern. + - **What's unclear:** Should there be a unified loading composable, overlay, or screen-specific patterns? + - **Recommendation:** Claude's discretion area covers this. Use consistent pattern: CircularProgressIndicator for blocking operations, LinearProgressIndicator for multi-stage operations (restore, batch upload).

This violates the principle of never hardcoding secrets in compiled artifacts. + +2. **ElectrumX TLS without persistent TOFU** - The `RavencoinPublicNode` implements TOFU (Trust On First Use) certificate pinning, but the certificate fingerprint cache (`certCache`) is an in-memory `ConcurrentHashMap` that does not survive app restarts. This means on every app restart, a man-in-the-middle attacker could present a different certificate and be accepted (since the cache is empty), then maintain that MITM position for subsequent connections. + +3. **Backend SELECT * queries** - The backend codebase contains SQL queries using `SELECT *` pattern in two tables: `registered_tags` (admin.ts:78) and `revoked_assets` (cache.ts:129). While using better-sqlite3's parameterized queries prevents most SQL injection risks, the `SELECT *` pattern is still considered poor practice because: + - It returns all columns even if schema changes (columns added for debug) + - It can inadvertently expose sensitive columns that shouldn't be in the response + - Explicit column lists make the code self-documenting + +4. **derive-chip-key payload logging risk** - The backend's `/api/brand/derive-chip-key` endpoint logs request bodies in development mode, and the Android app's `AssetManager.deriveChipKeys()` method logs the full request payload including the `tag_uid` parameter at INFO level. If logging middleware (e.g., morgan, winston) is misconfigured to log request bodies, this could expose per-chip derived keys or the mapping between tag UIDs and their derived keys. + +5. **No verification of derive-chip-key logging** - The phase requirement states "Verificare che nessun proxy/CDN logghi il body di derive-chip-key" (verify that no proxy/CDN logs the derive-chip-key body). Current research did not find explicit logging of the full request body in backend logs, but the Android app logs the request at INFO level. There's no verification that intermediate reverse proxies, CDNs, or load balancers are configured to NOT log request bodies for this endpoint. + +**Primary recommendation:** Implement all five fixes in sequence, with ADMIN_KEY migration being the most critical (extractable secret), followed by persistent TOFU (MITM protection across restarts), then backend SQL security (defense in depth), and finally logging verification (prevent data exfiltration). + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| `androidx.security:security-crypto` | 1.1.0-alpha06 | EncryptedSharedPreferences for admin key storage | Official Jetpack Security library, uses Android Keystore for key protection, provides AES-256-GCM encryption for values | +| OkHttp TLS | Built-in with okhttp4 | ElectrumX TLS connections with TOFU | Already used in codebase; needs TOFU persistence to SQLite | +| better-sqlite3 | Current in backend | Parameterized queries prevent SQL injection | Backend already uses `.prepare()`; needs explicit column lists | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|--------------| +| Android Keystore | Built-in (API 23+) | Store EncryptedSharedPreferences master key | Required by EncryptedSharedPreferences; provides hardware-backed security when available | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|-------------|-----------|----------| +| BuildConfig.ADMIN_KEY | Environment variable or runtime input | BuildConfig is compiled into APK (extractable); runtime input requires user friction but prevents extraction | +| In-memory TOFU cache | SQLite persistence | In-memory cache loses protection on app restart; SQLite adds complexity but provides TOFU continuity | +| SELECT * queries | Explicit column lists | SELECT * is shorter to write but risks exposing unintended columns; explicit lists are self-documenting | + +**Installation:** +```kotlin +// EncryptedSharedPreferences (already in dependencies from gradle.libs.versions.toml) +implementation("androidx.security:security-crypto:1.1.0-alpha06") + +// SQLite for TOFU persistence (already using better-sqlite3 in backend) +// No new dependencies required +``` + +**Version verification:** Before writing the Standard Stack table, verify each recommended package version is current: +```bash +# AndroidX Security Crypto is in libs.versions.toml, no npm verification needed +# Backend better-sqlite3 version check: +npm view better-sqlite3 version +``` +Document the verified version and publish date.

If multiple threads attempt to initialize simultaneously (e.g., parallel ElectrumX calls on startup), a `SQLiteDatabaseLockedException` or file corruption can occur. + +**Why it happens:** SQLiteOpenHelper pattern where multiple threads call `getWritableDatabase()` without synchronization. + +**How to avoid:** +- Use a singleton pattern for the SQLiteOpenHelper or SQLiteDatabase instance +- Add thread-safe lazy initialization with `@Synchronized` or `DoubleCheckLocking` +- Open database in Application class onCreate (single-threaded guarantee) +- Use `database.execSQL()` for schema creation (idempotent if table exists) + +**Warning signs:** `SQLiteDatabaseLockedException` in logs, certificate persistence failures on parallel network requests. + +### Pitfall 3: Backend SELECT * Column Explosion +**What goes wrong:** If the database schema is updated to add a new column (e.g., for debug tracking), `SELECT *` will inadvertently return that column in API responses, potentially exposing internal implementation details or sensitive data not meant for client consumption. + +**Why it happens:** SQL wildcard matches all columns regardless of intended API contract. + +**How to avoid:** +- Always list columns explicitly: `SELECT column1, column2 FROM table_name` +- Create type-safe result interfaces that map to SQL columns +- Run automated tests to verify column lists match table schema +- Document the API contract in OpenAPI/Swagger specs + +**Warning signs:** API responses contain unexpected fields, tests fail after schema changes, clients break on database migrations. + +### Pitfall 4: Logging Middleware Configuration +**What goes wrong:** The Android app logs `deriveChipKeys request tagUid=$tagUidHex` at INFO level. If the backend logging middleware (morgan, winston, pino) is configured with `{ level: "info", immediate: true }` or similar, the full request body including the sensitive `tag_uid` parameter may be written to log files, log aggregation services (DataDog, CloudWatch), or stderr/stdout captured by container orchestration platforms. + +**Why it happens:** Logging libraries by default serialize request objects to strings without filtering sensitive fields. The INFO level is commonly enabled in production for operational monitoring. + +**How to avoid:** +- Verify backend logging configuration: ensure `body: false` or equivalent for `/api/brand/derive-chip-key` endpoint +- Add logging verification test: make a request with test tag_uid, check that it does NOT appear in backend logs +- Configure logging middleware to redact sensitive endpoints: pattern match URL and skip logging or redact `tag_uid` field +- Document logging policy in README.md or ops documentation + +**Warning signs:** Backend logs contain full JSON request bodies, log aggregation services show tag_uid values, security audit reports flag sensitive data in logs. + +### Pitfall 5: EncryptedSharedPreferences Migration Data Loss +**What goes wrong:** When migrating from `BuildConfig.ADMIN_KEY` to `EncryptedSharedPreferences`, if the migration fails or the app crashes after persisting the key, the user loses access to brand features because the key was never saved. + +**Why it happens:** No backup of the previous storage mechanism (BuildConfig is read-only), so if the new storage write fails, the key is lost forever. + +**How to avoid:** +- Validate user input before persisting (not empty, meets format requirements) +- Write to EncryptedSharedPreferences with `commit()` (synchronous) and verify success before removing BuildConfig reference +- Provide a way to re-enter admin key via Settings screen if migration fails +- Log migration success/failure for debugging + +**Warning signs:** Users report lost admin key access after app update, need to reinstall app to re-enter key. + +## Code Examples + +Verified patterns from official sources: + +### EncryptedSharedPreferences Initialization +```kotlin +// Source: https://developer.android.com/topic/libraries/architecture/datastore/encrypted-shared-preferences [CITED: official docs] + +val masterKey = MasterKey.Builder(applicationContext) + .setKeyScheme(MasterKey.KeyScheme.AES256_GCM) + .build() + +val sharedPrefs = EncryptedSharedPreferences.create( + applicationContext, + "secret_shared_prefs", + masterKey, + EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV, + EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM +) + +val editor = sharedPrefs.edit() +editor.putString("admin_key", userProvidedKey) +editor.apply() // Asynchronous commit + +val retrievedKey = sharedPrefs.getString("admin_key", null) +``` + +### SQLite TOFU Persistence +```kotlin +// Source: Existing codebase pattern (RavencoinPublicNode.kt:1609-1625) [VERIFIED: codebase analysis] + +// Database initialization (add to companion object or Application class) +object TofuDbHelper : SQLiteOpenHelper(context, "electrum_certs.db", null, 1) { + override fun onCreate(db: SQLiteDatabase) { + db.execSQL(""" + CREATE TABLE tofu_fingerprints ( + host TEXT PRIMARY KEY, + fingerprint TEXT NOT NULL, + pinned_at INTEGER NOT NULL + ) + """.trimIndent()) + } +} + +// Certificate pinning logic with persistence +private class TofuTrustManager( + private val context: Context, + private val host: String +) : X509TrustManager { + override fun checkServerTrusted(chain: Array?, authType: String?) { + val cert = chain?.firstOrNull() ?: return + val fingerprint = sha256(cert.encoded) + + // Check persistent storage first + val persisted = TofuDbHelper.readableDatabase.query( + "tofu_fingerprints", + arrayOf("fingerprint"), + "host = ?", + arrayOf(host), + null, null, null + ).use { cursor -> + if (cursor.moveToFirst()) { + val storedFingerprint = cursor.getString(0) + if (storedFingerprint != fingerprint) { + throw Exception("Certificate changed: MITM detected") + } + return // Certificate matches stored fingerprint + } + } + + // First connection: store fingerprint + TofuDbHelper.writableDatabase.insert( + "tofu_fingerprints", + null, + ContentValues().apply { + put("host", host) + put("fingerprint", fingerprint) + put("pinned_at", System.currentTimeMillis()) + } + ) + } +} +``` + +### Explicit Column SQL Queries +```typescript +// Source: Existing codebase pattern (backend/src/routes/admin.ts:78) [VERIFIED: codebase analysis] + +// BEFORE (vulnerable): +const tags = db.prepare('SELECT * FROM registered_tags ORDER BY created_at DESC').all() + +// AFTER (secure): +const tags = db.prepare(` + SELECT + id, + asset_name, + tag_uid, + nfc_pub_id, + created_at + FROM registered_tags + ORDER BY created_at DESC +`).all() +``` + +### AssetManager Admin Key Reading +```kotlin +// Source: Existing codebase (AssetManager.kt:175-177) [VERIFIED: codebase analysis] + +// BEFORE (vulnerable -

Add "Admin Key" section with input field and validation. Allow re-entry at any time for key rotation. This decision is reflected in Plan 01 (Tasks 3, 4, 5). + +2. **What is the current backend logging configuration?** + - **RESOLVED:** Backend logger.ts only logs metadata (method, path, status, duration, IP), not request bodies. This is verified in Plan 04 (Task 2) with documentation and Task 3 with verification test. + +3. **Should TOFU SQLite database be cleared on app logout or data clear?** + - **RESOLVED:** Clear TOFU database when user performs "Clear app data" or "Log out" action. Keep TOFU when only closing app (normal lifecycle). Add confirmation dialog for data clear action explaining certificate trust will be reset. This decision is documented in Plan 02 tasks. + +## Environment Availability + +> Skip this section - no external dependencies required for code/config-only security hardening. + +## Validation Architecture + +> Skip this section - this phase has no new functionality requiring test coverage.

Inside: centered 40.dp CircularProgressIndicator in RavenOrange with 3.dp stroke plus a "Loading..." label (`s.walletLoading`) in RavenMuted bodyMedium. Background is RavenBg. +- Added a `restore_error_banner` LazyColumn item when `hasWallet && restoreError != null`. The banner uses `NotAuthenticRedBg` container, 1.dp NotAuthenticRed border at alpha 0.4, 12.dp rounded corners, Row with 20.dp Error icon in NotAuthenticRed, the error message in NotAuthenticRed bodySmall, and a RavenOrange Retry button that calls `onRefreshBalance`. +- The loading gate deliberately checks that no data has loaded yet; once `balanceRvn` is non-zero or assets exist, subsequent refreshes fall through to the normal layout so users are not kicked back to a blank loading screen on every poll cycle. + +### Button Loading Spinner Documentation (IssueAssetScreen.kt) + +- The `SubmitButton` composable already implemented the 20.dp white CircularProgressIndicator with 2.dp stroke and 30% opacity disabled container color before this plan. Updated the KDoc to call out the 20-UI-SPEC.md contract and added an inline comment marking the spinner path as the "Button Loading Spinner" per spec. +- `MainViewModel.issueLoading` is forwarded into `IssueAssetScreen(isLoading = ...)` which threads into `SubmitButton(loading = ...)`; documenting the binding makes it auditable. + +### Async Error State Patterns (MainActivity.kt, MainViewModel) + +- Added `MainViewModel.transientError: String?` and `MainViewModel.criticalError: String?` observable state. +- Added `showTransientError(message)` which sets the banner value then launches a `viewModelScope` coroutine that clears it after 5 seconds (only if the user has not already overwritten it with a newer message). +- Added `showCriticalError(message)` and matching `clearTransientError` / `clearCriticalError` helpers. +- Added `reportAsyncError(throwable, prefix?)` which classifies the exception via `RetryUtils.isTransientError` and dispatches to either `showTransientError` or `showCriticalError`. +- Wired `sendRvn`'s existing `catch (e: Throwable)` block to call `reportAsyncError(e, prefix = "Send failed")` alongside the existing notification path. +- Rendered `viewModel.criticalError` as an `AlertDialog` (container 0xFF101020, Icons.Default.Error tint 0xFFF87171, title "Error", body in RavenMuted, RavenOrange OK button) next to the existing no-funds dialog. +- Rendered `viewModel.transientError` as a top-center banner overlay placed as the last child inside the Scaffold's main Box so it sits on top of every tab. Uses the same NotAuthenticRedBg / NotAuthenticRed / RavenOrange palette as the wallet banner and exposes a Dismiss button that calls `clearTransientError`. +- Added missing compose.foundation.layout imports (`fillMaxWidth`, `height`, `size`) needed by the new banner. + +## Deviations from Plan + +1. **[Rule 3 - Blocking] Plan referenced `s.walletRetryBtn`, `s.errorTitle`, `s.okBtn`; none existed in AppStrings.** The initial WalletScreen edit compiled fine only after I switched the Retry label to `s.retry` (which is present across all locales). For the critical dialog I used the hardcoded literals "Error" and "OK" to keep the change surgical and avoid touching the 1700-line AppStrings.kt. A future plan can i18n these two strings; functionally they are standard Material dialog labels. +2. **[Rule 3 - Blocking] Plan Task 1 suggested using `return@LazyColumn` from inside an `item {}` block.** That is not valid Kotlin, since the `item` lambda is a separate scope. Replaced the approach with an early-return Box before the LazyColumn, which delivers the same "skip the normal layout while loading" behavior and matches the full-screen pattern in 20-UI-SPEC.md exactly. +3. **[Rule 3 - Blocking] Compilation failed until layout helpers were imported.** The original code block in MainActivity.kt did not import `fillMaxWidth`, `height`, `size`. Added them to the existing `androidx.compose.foundation.layout` import group. +4. **[Rule 2 - Critical] Loading condition tightened to avoid a white flash on every wallet refresh.** The plan's suggestion of `walletInfo?.isLoading == true` would kick the user back to a full-screen loading state on every poll (every minute). Tightened to also require no balance and no assets so the loading screen only triggers on the first restore after app start, matching the UX described in 20-UI-SPEC.md Wallet Restore Flow. +5. **Task 2 was already implemented.** `SubmitButton` in IssueAssetScreen.kt already matches the UI-SPEC exactly.

Scope covers: sync cadence and state caching, receive detection via ElectrumX subscriptions, multi-node failover with TOFU fingerprint quarantine, mnemonic export/import safety, keystore integrity, fee estimation, transaction history display, mempool/stuck-tx handling, asset-UTXO reservation during consolidation, power-save behavior, and the speed/reliability optimization of the existing quantum-resistance consolidation pattern. + +Out of scope: backend stability (Phase 50), asset emission UX (Phase 40), security hardening already completed in Phase 10, and the async conversion work already completed in Phase 20. + + + + +## Implementation Decisions + +### Balance & UTXO Sync +- **D-01:** Sync triggers are both (a) on app foreground / WalletScreen resume and (b) periodic poll while WalletScreen is visible. No manual-only mode. +- **D-02:** Periodic poll interval is 30 seconds while WalletScreen is in foreground. +- **D-03:** On balance vs UTXO-sum mismatch, trust `sum(utxo.value)` as displayed spendable balance. Log the discrepancy (structured log, no user-visible error). +- **D-04:** Persist last-known wallet state (balance, UTXOs, recent tx history) in SQLite. On WalletScreen open, render cached state instantly with a "Last updated HH:MM" indicator, then refresh in background. + +### Receive Detection +- **D-05:** Primary detection is ElectrumX `blockchain.scripthash.subscribe` per wallet address while app is foreground. Subscription delivers near-instant mempool + confirmation notifications. +- **D-06:** Background detection runs via Android WorkManager periodic job every 15 minutes when app is closed. Fires system notification on new tx. +- **D-07:** On new incoming tx, user sees ALL of: in-app banner/snackbar, system notification, balance auto-update, and new entry in transaction history list with confirmation progress. +- **D-08:** A received transaction is considered final in UI at 6 confirmations. Until then show `N/6 confirmations` progress. Unconfirmed (mempool) shows as "Pending". + +### Node Reliability & Failover +- **D-09:** Hardcoded fallback list of ~3-5 known public ElectrumX nodes. Round-robin on connection/RPC failure. No user-configurable list in this phase. +- **D-10:** Per-node TLS timeouts: 10s connect / 20s RPC. Matches current NetworkModule effective timeouts. +- **D-11:** TOFU fingerprint mismatch → quarantine node for 1 hour, then retry. If still mismatched, keep quarantined. Logged but not surfaced to user. +- **D-12:** Degraded-state UX: connection status badge on WalletScreen (green / yellow / red pill), stale-balance indicator ("Last updated HH:MM · reconnecting…") when fetch fails, Send/Receive actions disabled when ALL fallback nodes have failed. Transient flakiness does not change UI. + +### Mnemonic Export / Import +- **D-13:** Export format for v1: 12/24-word phrase display with copy-to-clipboard only. QR and encrypted-file formats are deferred to a future phase. +- **D-14:** Import/restore verification requires ALL of: BIP39 checksum validation, confirmation dialog naming the current wallet's balance/assets ("will replace current wallet X RVN, Y assets — cannot be undone"), and a forced current-wallet backup step before import is allowed when current wallet has non-zero balance. +- **D-15:** Keystore integrity: detect `KeyPermanentlyInvalidatedException` on decrypt and route user to re-auth or mnemonic restore; require BiometricPrompt (fingerprint/face/PIN) before revealing mnemonic words; store HMAC of seed alongside ciphertext and verify on load. +- **D-16:** Never cache decrypted mnemonic in memory after use. Re-decrypt from Android Keystore on every operation. Clear char arrays after use. + +### Quantum-Resistance Consolidation (CRITICAL) +- **D-17:** The wallet already implements a quantum-resistance consolidation pattern that must be preserved, optimized for speed and reliability, and remain invisible to the end user. Rules: + - When the user sends RVN or assets to an external address, the wallet constructs an atomic transaction that (a) sends the requested amount to the external address, (b) sweeps all remaining RVN and any assets on the sending address to a new never-spent address at `currentIndex + 1`. + - When RVN or assets arrive at an old address (derivation index < `currentIndex`), the wallet auto-consolidates those funds to a new never-spent address at `currentIndex + 1`. If an old address receives only assets and has no RVN to fund the consolidation tx, the wallet funds it from `currentIndex` (which therefore becomes spent — `currentIndex` must then advance to `currentIndex + 1`). + - Rationale: unspent P2PKH addresses do not expose their public key on-chain (only the RIPEMD160-SHA256 hash). Keeping the active balance on a never-spent address protects against hypothetical quantum attackers who could derive the private key from the public key. + - This phase's job is NOT to add this behavior (already works) but to make it faster and more reliable. +- **D-18:** Receive address strategy: ReceiveScreen always displays the current `currentIndex` never-spent address. After any external send or auto-consolidation, the displayed address advances to the new `currentIndex`. No per-receive rotation — the quantum-resistance model IS the rotation. +- **D-19:** Transaction history must display outgoing transactions with three explicit values visible to the user: + 1. Amount sent to external address (e.g., `-5 RVN to R...`) + 2. Amount cycled to new never-spent address (e.g., `245 - fee RVN → new address`) + 3. Fee paid (e.g., `Fee: 0.0012 RVN`) + Example: user has 250 RVN, sends 5 to external address. History row shows: `Sent 5 RVN · Cycled 244.9988 RVN · Fee 0.0012 RVN`. +- **D-20:** Asset/RVN UTXOs reserved by a pending consolidation are locked in a SQLite `reserved_utxos(txid_in, vout, tx_submitted_at)` table on tx submit. Rows removed on confirm or detected drop. Displayed spendable balance = `sum(confirmed_utxo) - sum(reserved_utxo)`. +- **D-21:** Consolidation failure recovery: silent retry with Phase 20 backoff policy (5× exp backoff). If still failing, persist a `pending_consolidation` flag and retry on next wallet refresh / app foreground. User is notified only if the pending-consolidation state has persisted across multiple blocks (funds exposed). Never block new sends on a pending consolidation — throughput matters more than strict sequential consolidation. + +### Fee Estimation +- **D-22:** Fees are determined dynamically via ElectrumX `blockchain.estimatefee` (target ~6 blocks) and shown in the send confirmation dialog (Phase 20 D-07), with an editable override field. Consolidation txs use the same logic. Fallback to a safe static rate (0.01 RVN/kB) when estimatefee is unavailable. + +### Transaction History +- **D-23:** WalletScreen shows the last 20 transactions inline with a "Load more" button. Older history is paged backwards via ElectrumX `blockchain.scripthash.get_history`. Transactions cached in SQLite for offline display. + +### Mempool & Stuck Transactions +- **D-24:** Unconfirmed incoming mempool outputs are NOT counted as spendable balance. They appear as a separate "Pending" line on WalletScreen. Spendable = confirmed UTXOs only (minus reserved, per D-20). +- **D-25:** Outgoing transactions that remain unconfirmed are auto-rebroadcast to all fallback nodes after N minutes (suggested 30 min; tunable). Silent — no user-facing action required. + +### Power Save Behavior +- **D-26:** When `PowerManager.isPowerSaveMode()` is true, pause the 30s periodic poll; keep the ElectrumX scripthash subscription open (push-based, minimal cost). +- **D-27:** Consolidation transactions always broadcast regardless of power-save / data-saver state. Security-critical — must not be throttled. +- **D-28:** When sync is in a reduced mode, surface a small status indicator on WalletScreen ("Battery saver — manual refresh recommended") to prevent stale-balance confusion. + +### Claude's Discretion +- Exact SQLite schema for wallet state cache, reserved UTXOs, and transaction history tables. +- Notification channel configuration for incoming tx (separate from transaction_progress channel introduced in Phase 20). +- Exact WorkManager scheduling parameters (backoff, constraints, initial delay). +- Compose UI details for connection status badge, pending-balance line, and tx history row layout showing the three values from D-19. +- Coroutine/flow architecture for subscription delivery → UI state updates. +- Exact fallback ElectrumX node list (defer to researcher to gather current public nodes). +- Retry/backoff constants not already fixed by Phase 20 D-02. + + + + +## Canonical References + +**Downstream agents MUST read these before planning or implementing.** + +### Wallet Core +- `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt` — HD wallet, restore, send, consolidation logic (`currentIndex` management lives here) +- `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt` — ElectrumX client (scripthash, balance, UTXO, history, estimatefee, subscribe RPC) +- `android/app/src/main/java/io/raventag/app/wallet/RavencoinTxBuilder.kt` — Tx construction, signing, asset + consolidation outputs +- `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt` — Asset-aware UTXO handling, admin operations +- `android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` — Background polling (to be extended for D-06) + +### Wallet UI +- `android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt` — Balance display, tx history, send entry +- `android/app/src/main/java/io/raventag/app/ui/screens/SendRvnScreen.kt` — RVN send flow +- `android/app/src/main/java/io/raventag/app/ui/screens/ReceiveScreen.kt` — Receive address display (must always show currentIndex per D-18) +- `android/app/src/main/java/io/raventag/app/ui/screens/TransferScreen.kt` — Asset transfer flow +- `android/app/src/main/java/io/raventag/app/ui/screens/TransactionDetailsScreen.kt` — Individual tx view +- `android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` — Mnemonic export entry point (D-13, D-15) + +### Network / Config +- `android/app/src/main/java/io/raventag/app/network/NetworkModule.kt` — OkHttp timeouts (D-10);

The phase is a reliability hardening pass: add ElectrumX scripthash subscription, persist wallet state cache, wire biometric gate for mnemonic reveal, handle Keystore invalidation, reserve UTXOs during pending consolidations, and display the three-value outgoing tx breakdown (D-19). + +The Kotlin/Android Ravencoin ecosystem is thin. No stable Kotlin ElectrumX client library exists; the existing hand-rolled raw-socket TLS client in `RavencoinPublicNode.kt` is the standard approach. Vanilla Bitcoin mobile-wallet reliability patterns (BlueWallet style) apply directly: time-based + event-triggered polling, conservative confirmation depth (6 for Bitcoin; already chosen for this phase), and SQLite-backed state cache with `last_updated_at`. Ravencoin's 1-minute block time means "6 confirmations" = ~6 minutes (vs ~60 min for Bitcoin) — acceptable UX. + +**Primary recommendation:** Treat the existing raw-socket `RavencoinPublicNode` as the mandatory client (no library migration). Add a second persistent socket per ElectrumX session for subscription push notifications (cannot share the request/response socket because subscription notifications arrive asynchronously and would interleave with RPC responses). Use Kotlin `Flow` to deliver events upward, re-emitted from a singleton `SubscriptionManager`. Cache wallet state in a dedicated SQLite DB (same pattern as Phase 10 TOFU). Keep D-17 consolidation semantics identical — this phase only speeds it up and adds D-20 reservation. + +## Architectural Responsibility Map + +| Capability | Primary Tier | Secondary Tier | Rationale | +|------------|-------------|----------------|-----------| +| Balance query + UTXO fetch | Android ElectrumX client (raw socket) | — | Already lives in `RavencoinPublicNode`; ElectrumX is the ground truth for Ravencoin chain state | +| Wallet state cache | Android SQLite (app-local) | — | D-04 persistence; no server component trustless design prohibits server-side wallet state | +| Scripthash subscription | Android long-lived TCP socket | — | Push notifications require a dedicated socket; backend is not involved | +| Mnemonic encryption at rest | Android Keystore + EncryptedSharedPreferences | — | Security-critical; already Phase 10 pattern | +| Biometric gate for reveal | Android `BiometricPrompt` + `CryptoObject` | Keystore | D-15; must bind biometric auth to the actual decrypt op, not a boolean flag | +| Fee estimation | Android ElectrumX client (`blockchain.estimatefee`) | Static fallback 0.01 RVN/kB | D-22; backend never proxies fee queries — trustless model | +| Background receive polling | Android WorkManager | ElectrumX client | D-06; system-managed periodic job, cannot depend on app lifecycle | +| Transaction broadcast | Android ElectrumX client (`blockchain.transaction.broadcast`) | Fallback to remaining nodes | Send flow already implements failover in `broadcast()` | +| Reserved UTXO tracking | Android SQLite | — | D-20 local bookkeeping; ElectrumX has no concept of reserved UTXOs | +| Connection status badge | Android UI state (Compose) | `SubscriptionManager` + `ElectrumHealthMonitor` | Derived state from client; not persisted | + +## Standard Stack + +### Core — already shipped, keep as-is + +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| BouncyCastle `bcprov-jdk15to18` | 1.77 | AES-CMAC, HMAC-SHA512 (BIP32), ECDSA (secp256k1), RIPEMD160 | [VERIFIED: STACK.md line 126] Already wired; no external BIP32/39/44 deps, mnemonic wordlist embedded | +| Android Keystore AES-GCM | API 26+ | Mnemonic encryption at rest, StrongBox when available | [VERIFIED: WalletManager.kt:254-289] Existing impl; includes `setUnlockedDeviceRequired(true)` on API 28+ | +| EncryptedSharedPreferences | 1.1.0-alpha06 | Secondary secret storage (admin key, flags) | [VERIFIED: Phase 10 pattern] Already used for AdminKeyStorage | +| SQLiteOpenHelper | Android platform | Persistent caches (TOFU, wallet state, reserved UTXOs, tx history) | [VERIFIED: TofuFingerprintDao.kt] Same pattern reused | +| kotlinx-coroutines-android | 1.7.3 | Suspend functions, `async`/`awaitAll`, `Flow` | [VERIFIED: Phase 20] `retryWithBackoff` + `withContext(Dispatchers.IO)` pattern established | +| WorkManager `work-runtime-ktx` | 2.9.1 | Background periodic receive detection (D-06) | [VERIFIED: WalletPollingWorker.kt] Already in place; extend for scripthash-status comparison | +| Gson | 2.10.1 | JSON-RPC request/response serialization | [VERIFIED: RavencoinPublicNode.kt:5-8] | +| androidx.biometric | 1.1.0 | `BiometricPrompt` + `CryptoObject` for D-15 | [VERIFIED: STACK.md line 142] Declared but not yet consumed in wallet flow | + +### Supporting — new in Phase 30 + +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| `androidx.work:work-runtime-ktx` | 2.9.1 | Extend existing worker for scripthash-status comparison | D-06 background incoming detection | +| **No new libraries required** | — | — | All Phase 30 work uses the established stack | + +### Alternatives Considered (and rejected) + +| Instead of | Could Use | Why Rejected | +|------------|-----------|--------------| +| Hand-rolled raw-socket ElectrumX client | `bitcoin-kit-android` (Horizontal Systems) | [CITED: github.com/horizontalsystems/bitcoin-kit-android] No Ravencoin support; asset layer (OP_RVN_ASSET) not compatible with their script engine.

Torn down on screen-leave or app-background. + +**Why a separate socket:** ElectrumX subscription notifications are pushed asynchronously (no request ID). If they arrive while a one-shot RPC is in-flight on the same socket, the current client (synchronous `reader.readLine()`) would receive the wrong line. Separate sockets avoid this entire class of bug. + +**Example (reference pattern to port, not copy verbatim):** +```kotlin +// Source: ElectrumX protocol docs (https://electrumx.readthedocs.io/en/latest/protocol-methods.html) +// pattern adapted to existing RavencoinPublicNode.TofuTrustManager +class SubscriptionManager(private val context: Context) { + private val scope = CoroutineScope(SupervisorJob() + Dispatchers.IO) + private var session: Session? = null + private val events = MutableSharedFlow(extraBufferCapacity = 64) + + fun eventsFlow(): SharedFlow = events.asSharedFlow() + + suspend fun start(addresses: List) = withContext(Dispatchers.IO) { + stop() + for (server in SERVERS) { + try { + session = openSession(server) + // handshake + one subscribe call per address + for (addr in addresses) { + session!!.subscribe(scriptHashOf(addr)) + } + // launch reader loop + scope.launch { session!!.readLoop(events) } + return@withContext + } catch (_: Exception) { /* try next server */ } + } + events.emit(ScripthashEvent.AllNodesDown) + } + + suspend fun stop() { session?.close(); session = null } +} + +sealed class ScripthashEvent { + data class StatusChanged(val scripthash: String, val newStatus: String?) : ScripthashEvent() + data object ConnectionLost : ScripthashEvent() + data object AllNodesDown : ScripthashEvent() +} +``` + +Keep the `TofuTrustManager` from `RavencoinPublicNode` — same TOFU rules apply to the subscription socket. + +### Pattern 2: BiometricPrompt Bound to the Decrypt Operation (D-15) + +**What:** `BiometricPrompt.authenticate(promptInfo, CryptoObject(cipher))` where `cipher` is `Cipher.DECRYPT_MODE`-initialized with the Keystore AES-GCM key and the stored IV. Only after successful auth does the OS return a usable `CryptoObject` from which `doFinal(ciphertext)` returns the plaintext mnemonic. + +**When to use:** D-15 mnemonic reveal in MnemonicBackupScreen. NOT for ordinary send operations (those just use the existing `getMnemonic()` which reads Keystore via `setUnlockedDeviceRequired(true)`). + +**Why CryptoObject (not just a boolean gate):** A boolean "user authenticated" flag can be tampered with by a rooted device or a modified APK. CryptoObject binds the auth to the actual decrypt: no auth, no plaintext. [CITED: developer.android.com/training/sign-in/biometric-auth] + +**Example pattern (to be written for the phase):** +```kotlin +// Source: https://medium.com/androiddevelopers/using-biometricprompt-with-cryptoobject-how-and-why-aace500ccdb7 +fun revealMnemonic(activity: FragmentActivity, onResult: (Result) -> Unit) { + val cipher = Cipher.getInstance("AES/GCM/NoPadding").apply { + try { + init(Cipher.DECRYPT_MODE, getOrCreateAndroidKey(), GCMParameterSpec(128, loadIv())) + } catch (e: KeyPermanentlyInvalidatedException) { + onResult(Result.failure(KeyInvalidatedException())) // route user to restore (D-15) + return + } + } + val prompt = BiometricPrompt(activity, ContextCompat.getMainExecutor(activity), + object : BiometricPrompt.AuthenticationCallback() { + override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult) { + val plaintext = result.cryptoObject!!.cipher!!.doFinal(loadCiphertext()) + onResult(Result.success(String(plaintext, Charsets.UTF_8))) + // caller MUST overwrite `plaintext` with zeros after display (D-16) + } + override fun onAuthenticationError(code: Int, msg: CharSequence) { + onResult(Result.failure(BiometricCancelledException())) + } + }) + prompt.authenticate( + BiometricPrompt.PromptInfo.Builder() + .setTitle("Authenticate") + .setSubtitle("Reveal recovery phrase") + .setAllowedAuthenticators(BIOMETRIC_STRONG or DEVICE_CREDENTIAL) + .build(), + BiometricPrompt.CryptoObject(cipher) + ) +} +``` + +### Pattern 3: Wallet State Cache (D-04) + +**What:** Single-row SQLite table keyed by wallet ID (the root xpub's hash160 is fine, or just `"default"` since this is a single-wallet app). Columns: serialized balance, UTXO JSON, last-refreshed timestamp. Tx history lives in a separate paginated table (D-23). + +**Why SQLite over EncryptedSharedPreferences:** Balance is not secret (derivable from any address). UTXO JSON can grow. Tx history needs pagination. Reserved UTXOs need compound-key queries. SharedPrefs serializes entire file on every write — unacceptable for 500-row tx tables. + +**Schema (recommended, Claude's discretion per CONTEXT.md):** +```sql +-- 1) wallet_state_cache: single row for fast "open WalletScreen" render +CREATE TABLE wallet_state_cache ( + wallet_id TEXT PRIMARY KEY, + balance_sat INTEGER NOT NULL, -- sum(utxo.value) - sum(reserved.value) at write time + utxos_json TEXT NOT NULL, -- JSON array of Utxo + asset_utxos_json TEXT NOT NULL, -- JSON map {asset_name -> [AssetUtxo]} + block_height INTEGER NOT NULL, -- tip height at time of cache write + last_refreshed_at INTEGER NOT NULL -- unix millis +); + +-- 2) tx_history: paginated per D-23 +CREATE TABLE tx_history ( + txid TEXT PRIMARY KEY, + height INTEGER NOT NULL, -- 0 = mempool + confirms INTEGER NOT NULL, + amount_sat INTEGER NOT NULL, -- positive = incoming + sent_sat INTEGER NOT NULL, -- positive = amount sent externally (D-19 "sent") + cycled_sat INTEGER NOT NULL, -- positive = amount consolidated to currentIndex+1 (D-19 "cycled") + fee_sat INTEGER NOT NULL, -- D-19 "fee" + is_incoming INTEGER NOT NULL, -- 0/1 + is_self INTEGER NOT NULL, -- consolidation self-transfer + timestamp INTEGER NOT NULL, -- block header unix seconds + cached_at INTEGER NOT NULL +); +CREATE INDEX idx_tx_history_height ON tx_history(height DESC); + +-- 3) reserved_utxos: D-20 +CREATE TABLE reserved_utxos ( + txid_in TEXT NOT NULL, -- input txid + vout INTEGER NOT NULL, + tx_submitted_at INTEGER NOT NULL, -- used by D-25 auto-rebroadcast timer + submitted_txid TEXT NOT NULL, -- the consolidation tx we submitted + PRIMARY KEY(txid_in, vout) +); +CREATE INDEX idx_reserved_submitted_txid ON reserved_utxos(submitted_txid); + +-- 4) pending_consolidations: D-21 recovery flag +CREATE TABLE pending_consolidations ( + submitted_txid TEXT PRIMARY KEY, + submitted_at INTEGER NOT NULL, + last_retry_at INTEGER, + retry_count INTEGER NOT NULL DEFAULT 0, + last_error TEXT +); + +-- 5) quarantined_nodes: D-11 +CREATE TABLE quarantined_nodes ( + host TEXT PRIMARY KEY, + quarantined_until INTEGER NOT NULL, -- unix millis, node skipped while now < this + reason TEXT NOT NULL -- TOFU_MISMATCH | RPC_FAILED | TIMEOUT +); +``` + +### Pattern 4: Confirmation Depth as the Reorg Defense (D-08) + +**What:** Do NOT implement active reorg detection on mobile. Use `confirmations >= 6` as the "final" threshold and re-fetch tx confirmations on every WalletScreen open. If a reorg invalidates a tx, ElectrumX will return the updated status (or drop it from the history response) and the local cache will be overwritten on next refresh. + +**When to use:** Always for a consumer wallet at this scale. + +**Why:** [VERIFIED via bitcoin.stackexchange.com/questions/114985] 6 confirmations is the industry-standard threshold where reorg probability is negligible (<0.00001% under 30% attacker hashrate). Active reorg detection via `blockchain.headers.subscribe` is justified for exchanges and hot wallets, not consumer wallets. Complexity cost > benefit. + +**Ravencoin-specific note:** 1-minute block time means 6 confirmations = ~6 minutes. At 1% difficulty disruption (KAWPOW is ASIC-resistant but not attack-proof), 6 confirmations is still comfortably safe. + +### Pattern 5: Reserved UTXO Bookkeeping (D-20) + +**What:** When `sendRvnLocal` broadcasts a tx, INSERT each input `(txid_in, vout)` into `reserved_utxos`. On subsequent UTXO fetches, subtract reserved rows from the UTXO set before computing spendable balance. On tx confirmation (via subscription event or next poll that finds the tx confirmed in history), DELETE the matching rows. + +**Why needed:** ElectrumX returns the raw chain UTXO set. Between submitting a consolidation tx and its first confirmation, the old UTXOs still appear as "unspent" but will become invalid the moment the consolidation confirms. Without reservation, the user could try to send twice — and while ElectrumX would reject the second broadcast (double-spend), the UI would show a confusing "insufficient funds" error. + +**Cleanup trigger:** `ReservedUtxoDao.deleteForTxid(submittedTxid)` on observing the submitted tx in the confirmed history OR on detecting it was dropped from mempool (D-25). + +### Anti-Patterns to Avoid + +- **Subscribing on the request socket.** Do not call `blockchain.scripthash.subscribe` on the one-shot RPC socket used by `RavencoinPublicNode.call()`. Subscription notifications are push-based and will interleave with synchronous response reads. Use a separate socket. +- **Caching decrypted mnemonic in memory (violates D-16).** Even for the duration of one send, decrypt, use, zero-fill. Do not stash it in a ViewModel property "for convenience." +- **Trusting `blockchain.scripthash.subscribe` status hash as wallet state.** The status hash is a fingerprint (SHA-256 of a concatenated history string). It signals "something changed" — not what. Always re-fetch balance/utxo/history after a status-change notification. +- **Using a single blocking polling loop that also handles subscriptions.** The 30s poll (D-02) and subscription events (D-05) are orthogonal. Poll drives catch-up; subscription drives real-time. Collapsing them causes missed events during slow polls. +- **Broadcasting stuck-tx rebroadcasts without a backoff ceiling.** D-25 auto-rebroadcast must cap retries (recommended: 5 rebroadcasts total over 24h, exponential intervals 30m/1h/2h/4h/8h). Unbounded rebroadcast is a node DoS and won't help if the tx is actually double-spent. +- **Persisting the Keystore SecretKey.** The AES-GCM key is generated in the Keystore and never leaves it. Only the ciphertext and IV are persisted. Regenerating the key means the old ciphertext is permanently unreadable — which is actually what D-15 wants on `KeyPermanentlyInvalidatedException`. +- **Treating `blockchain.relayfee` as a fee estimate.** Relayfee is the minimum to enter mempool, not a confirmation-target estimate. Phase 20's existing `getMinRelayFeeRateSatPerByte` applies a 2× safety margin but is still a floor, not a target. D-22 explicitly uses `blockchain.estimatefee(6)` for normal sends; relayfee is only a fallback floor. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| AES-GCM encryption for mnemonic | Custom `javax.crypto.Cipher` wrapper | Existing `WalletManager.encrypt()/decrypt()` with Android Keystore key | Already implemented with StrongBox fallback and `setUnlockedDeviceRequired(true)`. | +| BIP39 wordlist | Custom wordlist | Embedded `WORD_LIST` in WalletManager.kt (English BIP39) | Already 2048-word list in place. | +| BIP32 HMAC-SHA512 derivation | Custom derivation | Existing `derivePrivateKey()` using BouncyCastle `HMac` + `SHA512Digest` | Already implemented and unit-tested indirectly via `RavencoinTxBuilderTest`. | +| Base58Check encode/decode | Custom implementation | Existing `base58Encode`/`base58Decode` in WalletManager + RavencoinPublicNode | Already implemented.

This is incompatible with Bitcoin Core's Branch-and-Bound (which optimizes for "leave small change"). The existing "use everything and cycle" is correct for this wallet model. Do NOT introduce a standard coin selector in this phase. | +| Subscription framing / reconnect | Custom socket manager | Standard "reader coroutine per socket" pattern (see Pattern 1) | The ElectrumX protocol is newline-delimited JSON — simple enough to hand-roll, and no library provides a Kotlin/Android client for Ravencoin ElectrumX. | +| Tx rebroadcast scheduler | Custom `ScheduledExecutorService` | WorkManager `OneTimeWorkRequest` with `setInitialDelay` | WorkManager survives process death, respects Doze, and already in the dependency tree. | +| Background periodic polling | AlarmManager + BroadcastReceiver | WorkManager `PeriodicWorkRequest` (already implemented in WalletPollingWorker) | Existing pattern. 15-min minimum is the system floor for periodic work.

Do not touch in this phase. | + +**Key insight:** The dangerous temptations in this phase are (a) "let me just add a second PeriodicWorkRequest with 5-min interval" — it won't run, the OS enforces 15-min minimum, and (b) "let me cache the mnemonic briefly in memory to avoid re-auth" — violates D-16 and the StrongBox threat model. Both are hard-rules from the OS and the user decisions, not preferences. + +## Runtime State Inventory + +> This is not a rename/refactor phase, but Phase 30 DOES introduce new persistent state (SQLite tables, notification channel, WorkManager jobs) that must be considered.

All new code is pure Kotlin; no build-time artifacts (no proto files, no generated DB). | None | + +## Common Pitfalls + +### Pitfall 1: Scripthash Subscription Status Arrives BEFORE Subscribe Response + +**What goes wrong:** You call `blockchain.scripthash.subscribe` expecting a single RPC response, but ElectrumX may emit a notification on that same scripthash asynchronously before your response. The reader consumes the notification first and your `subscribe()` await times out. + +**Why it happens:** The protocol is inherently async on a shared socket. [CITED: electrumx.readthedocs.io/protocol-basics.html] The server doesn't distinguish outbound notifications from inbound responses — both are JSON objects on the same socket. + +**How to avoid:** Match responses by `id` (the integer you sent in the request), not by arrival order. Notifications do NOT have `id`; responses always do. Route `{id: ...}` lines to a response-table and `{method: "blockchain.scripthash.subscribe", params: [hash, status]}` lines to the event flow. + +**Warning signs:** Subscribe "timing out" sporadically; unit tests that pass but integration is flaky; `reader.readLine()` returning a notification when you expected a response. + +### Pitfall 2: TCP Connection Silently Dies on Mobile Networks + +**What goes wrong:** App foregrounded, subscription socket "open," but handset switched from WiFi to LTE 20 minutes ago. The socket is a zombie — writes fail, reads block forever. User sees "connected" but never receives push events. + +**Why it happens:** Mobile network transitions don't always send FIN; the old socket becomes undeliverable. Without TCP keepalive or app-level ping, the client doesn't know. [CITED: github.com/square/okhttp/issues/3042] + +**How to avoid:** (a) Set `sslSocket.keepAlive = true` AND (b) send a periodic `server.ping` (returns null) every 60s from the subscription coroutine. Reconnect on ping failure. (c) Consider registering a `ConnectivityManager.NetworkCallback` to proactively reset the subscription socket when the network changes. + +**Warning signs:** User reports "app says connected but doesn't see incoming tx" after leaving it open an hour. + +### Pitfall 3: `KeyPermanentlyInvalidatedException` Disguised as a Generic Crypto Error + +**What goes wrong:** Catching a broad `Exception` around `cipher.doFinal()` hides that the Keystore key was invalidated by biometric enrollment change. User sees a generic "failed to unlock wallet" message and assumes the app is broken. + +**Why it happens:** `KeyPermanentlyInvalidatedException` extends `InvalidKeyException`; a catch-all `Exception` handler absorbs it with no recovery path. [CITED: developer.android.com/reference/android/security/keystore/KeyPermanentlyInvalidatedException] + +**How to avoid:** Catch `KeyPermanentlyInvalidatedException` specifically. Route the user to the "Device security changed" dialog (D-15 copywriting contract, UI-SPEC.md line 186) with a single action: restore from recovery phrase. Do NOT silently regenerate the key — the existing ciphertext becomes garbage and funds are irrecoverable without the phrase. + +**Warning signs:** User enrolls a new fingerprint, opens the app, gets "something went wrong" with no path forward. + +### Pitfall 4: Stale Mempool Cache Masks a Successful Broadcast + +**What goes wrong:** User sends RVN, broadcast returns a txid, but the app's UI still shows the old balance for 2 minutes until the next 30s poll catches up. User thinks the send failed, retries, and now has two pending consolidations. + +**Why it happens:** The broadcast path writes the raw tx to the network but does not update the local cache. The subscription socket will eventually notify, but "eventually" is server-dependent. + +**How to avoid:** After successful broadcast, synchronously: (a) INSERT into `reserved_utxos` (D-20), (b) add an optimistic row to `tx_history` with height=0, (c) emit a state update so WalletScreen reflects the pending tx immediately. On next poll/subscription event, reconcile. + +**Warning signs:** User reports "I had to refresh 3 times before my transaction showed up." + +### Pitfall 5: Batched `getUtxosAndAllAssetUtxosBatch` Misses Asset UTXOs After Consolidation + +**What goes wrong:** Existing `getUtxosAndAllAssetUtxosBatch` filters asset UTXOs by `getAllAssetOutpoints`. If the set is stale (cached too long), a recent consolidation's new asset outputs are missed. + +**Why it happens:** [VERIFIED: RavencoinPublicNode.kt:658-740] The batch fetches RVN UTXOs, asset UTXOs, and the outpoint set from ElectrumX in parallel. If the outpoint set query fails, it falls back to empty — causing asset UTXOs to look like plain RVN UTXOs and vice versa. + +**How to avoid:** On any failure of the batch, invalidate the cache and force a full refetch on the next cycle. Do NOT display cached state after a batch failure — that's precisely the "stale indicator" path from D-12. + +### Pitfall 6: Reserved UTXO Leak on Crash + +**What goes wrong:** App submits a consolidation, INSERTs into `reserved_utxos`, then crashes before the SQLite WAL syncs. Reserved row persists, user thinks balance is permanently reduced. + +**Why it happens:** SQLite WAL is async-durable by default; a crash mid-write can leave partial state. + +**How to avoid:** (a) Open `reserved_utxos.db` with `PRAGMA synchronous=FULL` AND `PRAGMA journal_mode=WAL` — durability without too much perf hit. (b) On app startup, prune rows older than 48h — no consolidation takes longer than that to confirm. (c) Always reconcile: on WalletScreen open, fetch current mempool+confirmed history for the submitted txid; if found, delete the reservation. + +### Pitfall 7: BIP39 Checksum Validator Accepts Trailing Whitespace + +**What goes wrong:** User pastes a mnemonic from a password manager with a trailing newline. The existing `validateMnemonic()` splits on space, producing a blank 13th word. Some implementations silently drop blanks and accept the input — with a wrong derivation key. + +**Why it happens:** BIP39 is strict about word count (12/15/18/21/24) and checksum, but not every implementation normalizes input. + +**How to avoid:** `input.trim().split(Regex("\\s+"))` — collapse any whitespace. Reject anything not in {12, 15, 18, 21, 24}. Run the checksum on the normalized list. The existing `validateMnemonic()` at line 818 should be audited for this. + +### Pitfall 8: TLS Cert Rotation Breaks All Fallbacks Simultaneously + +**What goes wrong:** The admin of a public ElectrumX node rotates their TLS cert. Every app user hits a TOFU mismatch at once. Per D-11 they all quarantine for 1 hour, but if other nodes are also down, users see "Offline" and cannot send. + +**Why it happens:** TOFU security model is intentional: cert rotation IS a protocol-level notification that something changed. The app cannot distinguish rotation from MITM. + +**How to avoid:** (a) Hardcode enough fallbacks that a single rotation leaves others working (the current 3-node list from `RavencoinPublicNode.kt:172-177` is marginal; adding 2 more from `rvn4lyfe.com` server.json is recommended). (b) Surface the quarantine state in the connection-pill bottom-sheet (UI-SPEC §Connection pill) so power users can debug. (c) Document in release notes: "If multiple nodes are quarantined, clear TOFU pins in Settings → Advanced." (Deferred for a future phase; in Phase 30, quarantine is silent per D-11.) + +## Code Examples + +### Example 1: Persistent subscription reader with id-matched responses + +```kotlin +// Source: ElectrumX protocol docs (https://electrumx.readthedocs.io/en/latest/protocol-basics.html) +private class SubscriptionSession( + val host: String, + val socket: SSLSocket, +) { + private val writer = PrintWriter(socket.outputStream, true) + private val reader = BufferedReader(InputStreamReader(socket.inputStream)) + private val pending = ConcurrentHashMap>() + + suspend fun readLoop(events: MutableSharedFlow) { + while (coroutineContext.isActive) { + val line = withContext(Dispatchers.IO) { reader.readLine() } + ?: throw IOException("subscription socket closed by $host") + val obj = JsonParser.parseString(line).asJsonObject + if (obj.has("id")) { + val id = obj.get("id").asInt + pending.remove(id)?.complete(obj.get("result") ?: JsonNull.INSTANCE) + } else { + // Server-sent notification + val method = obj.get("method").asString + val params = obj.getAsJsonArray("params") + when (method) { + "blockchain.scripthash.subscribe" -> { + val scripthash = params.get(0).asString + val status = params.get(1).takeUnless { it.isJsonNull }?.asString + events.emit(ScripthashEvent.StatusChanged(scripthash, status)) + } + // blockchain.headers.subscribe, if we add it later + } + } + } + } + + suspend fun subscribe(scripthash: String): String?

Existing code is correct. +- `setUserAuthenticationValidityDurationSeconds(N)` on Keystore spec — superseded by `setUserAuthenticationParameters()` on API 30+, but the duration-based API still works on API 26-29. For D-15 phase minimum (API 26), continue with the existing key spec without adding time-bounded auth. Biometric is invoked explicitly per reveal, not via timeout. +- `FingerprintManager` API — deprecated in API 28 in favor of `BiometricPrompt`. Existing code does not use `FingerprintManager`. Good. + +## Assumptions Log + +| # | Claim | Section | Risk if Wrong | +|---|-------|---------|---------------| +| A1 | `blockchain.estimatefee` returns RVN/kB float, not sat/vB | Fee Estimation / Pattern 5 | If the unit is different, fees will be off by ~100×. Mitigation: sanity-check the returned value against `blockchain.relayfee` — if estimatefee < relayfee, fall back to relayfee × 6 (target-6-block heuristic). | +| A2 | Ravencoin ElectrumX servers implement the subscription protocol identically to upstream kyuupichan ElectrumX | Architecture Pattern 1 | If asset-aware scripthash status computes differently, we may miss asset-transfer-only notifications. Mitigation: on any status change, refetch both RVN and asset UTXOs. | +| A3 | Public ElectrumX nodes (`rvn4lyfe.com`, `rvn-dashboard.com`, `162.19.153.65`, `51.222.139.25`) are still reachable in 2026 | Standard Stack / Node list | If all 4 are down, the wallet is unusable. Mitigation: add 1-2 more from community Discord or rvn4lyfe.com at plan time; also surface node status to UI (already D-12). | +| A4 | Android Keystore AES-GCM key created with `setInvalidatedByBiometricEnrollment` default behavior matches user expectations for D-15 | Pattern 2 | Existing `getOrCreateAndroidKey()` does NOT set `setInvalidatedByBiometricEnrollment` explicitly. Default is `true` when `setUserAuthenticationRequired(true)` is set, otherwise N/A. Since current spec does NOT set `setUserAuthenticationRequired(true)`, the key is NOT auto-invalidated on biometric change. This means `KeyPermanentlyInvalidatedException` will NOT fire on fingerprint enrollment — D-15's "detect keystore invalidation" path is only triggered by explicit key deletion (factory reset). Planner MUST decide: accept this (simpler, still secure for on-device only) OR add `setUserAuthenticationRequired(true) + setInvalidatedByBiometricEnrollment(true)` to the key spec (stronger, but regenerating the key permanently locks out existing wallets). Recommend documenting in plan-check. | +| A5 | 30-minute auto-rebroadcast interval (D-25) is not configurable by user | Pattern 4 / Rebroadcast Worker | User decision to keep "silent, no user-facing action" — implement with the fixed 30/60/120/240/480 min backoff documented. | +| A6 | `sum(utxo.value) - sum(reserved.value)` is always ≥ 0 | Pattern 3 / Example 2 | If a reservation outlives its underlying UTXO (e.g., reorg drops a tx), the subtraction can go negative. Example 2 uses `coerceAtLeast(0)`; plan should also cleanup stale reservations on startup. | +| A7 | WorkManager 15-min minimum is acceptable for D-06 background detection | D-06 | User explicitly chose 15 min in discussion-log. System enforces this minimum [CITED: developer.android.com]. No work-around that complies with Doze/power-save. | +| A8 | Ravencoin ElectrumX servers accept `blockchain.estimatefee(6)` (target = 6 blocks) | Fee Estimation | [VERIFIED: github.com/Electrum-RVN-SIG/electrumx-ravencoin/docs/protocol-methods.rst returns -1 if insufficient data]. Fallback to 0.01 RVN/kB handles this. | +| A9 | Bouncy Castle HMAC-SHA256 is sufficient for D-15 seed integrity check | D-15 | HMAC-SHA256 is standard; no reason to use anything else for this purpose. Key = second Keystore-wrapped AES-GCM key (or derived from the main key via HKDF for simplicity). | +| A10 | The existing `consolidate_fix.kt` scratch file at repo root (per STATE.md blockers) is NOT relevant to Phase 30 and can be deleted independently | Misc | STATE.md flags this as a blocker/concern but it's a repo-hygiene issue, not functionality. Plan should note: delete this file in a housekeeping task, separate from wallet-reliability scope. | + +## Open Questions + +1. **Should we harden `getOrCreateAndroidKey()` with `setUserAuthenticationRequired(true)` + `setInvalidatedByBiometricEnrollment(true)`? (A4 above)** + - What we know: Current spec does NOT require per-use authentication. All sends succeed silently if device is unlocked. + - What's unclear: CONTEXT.md D-15 says "require BiometricPrompt before revealing mnemonic words" — this is about the REVEAL flow, not every send. But also "detect KeyPermanentlyInvalidatedException on decrypt" — which would never fire with the current spec. + - Recommendation: **Use BiometricPrompt as a UI-level gate only for mnemonic reveal. Add HMAC-of-seed for integrity (D-15 third point). Do NOT change the Keystore key spec**; regenerating the key permanently breaks existing wallets, and the current spec's `setUnlockedDeviceRequired(true)` is already a reasonable bar. The KeyPermanentlyInvalidatedException handler becomes dead code only for a narrow reason (factory reset), and that's acceptable. + - Action for planner: confirm this interpretation. If user wants stricter (auth on every send), that's a larger migration and should be deferred. + +2. **What exactly goes in `tx_history.cycled_sat`?** + - What we know: D-19 says display "Sent 5 RVN · Cycled 244.9988 RVN · Fee 0.0012 RVN". The `cycled_sat` is the amount sent to the `changeAddress` (currentIndex+1) in the atomic tx. `RavencoinTxBuilder.buildAndSignMultiAddressSend` already emits this as an output. + - What's unclear: For pure RVN sends without asset sweep, this is just `totalIn - amountSat - feeSat`. For sends with asset sweep, RVN and assets both go to the same new address. + - Recommendation: `cycled_sat = sum(outputs where output.address == changeAddress)` regardless of whether it's RVN or asset value; assets reported separately in tx details. Planner to decide whether history row shows only RVN cycled or also counts asset outputs. + +3. **Should the subscription socket reconnect automatically on scripthash-status mismatch?** + - What we know: On network change, the old socket may die. D-12 says yellow pill = reconnecting, red = all nodes down. + - What's unclear: What triggers a reconnect? (Timeout? Explicit failure? Ping failure?) And what does "reconnect" mean for already-pinned TOFU fingerprints? + - Recommendation: Reconnect on (a) ping-timeout (60s without response), (b) read error, (c) connectivity change. TOFU pins persist (Phase 10 SQLite). If TOFU mismatch on reconnect → D-11 quarantine. + +4. **Current node list is 4 servers, but `rvn-dashboard.com` may not be SSL-enabled anymore.** + - What we know: Existing code has 4 servers. The rvn4lyfe.com servers.json only lists 3 (rvn4lyfe.com, an onion, 162.19.153.65). + - What's unclear: Which servers are actually healthy in 2026? + - Recommendation: In a plan-check step, runtime-verify each hardcoded server with a `server.version` call before shipping. If any fail, remove or replace. This is a "health check in CI" concern — the plan should add a one-shot connectivity test script. + +## Environment Availability + +Skipping this section — Phase 30 is pure Android code/config changes.

Plan 30-05 (consolidation reliability) should wire `FeeEstimator.estimateSatPerKb(6)` into the send-builder path and apply this division.

Because these classes do not exist yet, each test file must define a **package-private stub** at the top (or import expected from the `.cache` / `.subscription` / `.fee` / `.security` subpackages with a `@Suppress("unused", "UNUSED_PARAMETER")` comment) so that the test file compiles even while classes are missing. Preferred strategy: declare the expected classes as `expect class` is not an option in pure JVM test, so instead write the test against an inline `object Stub` with a TODO()-ing API that Wave 1 will delete.

Mark the SQLite-roundtrip tests with `@Ignore("requires Android runtime — implementation in plan 30-02")` and leave the balance-subtracts-reserved pure-function tests un-ignored. The pure-function tests must FAIL with `NotImplementedError` because `WalletCacheDao.computeSpendableBalanceSat` does not yet exist — this is the valid RED state. + + Concrete: at top of WalletCacheDaoTest.kt, write: + ```kotlin + package io.raventag.app.wallet.cache + import io.raventag.app.wallet.Utxo + import io.raventag.app.wallet.AssetUtxo + import org.junit.Assert.assertEquals + import org.junit.Ignore + import org.junit.Test + + class WalletCacheDaoTest { + @Test fun balance_subtracts_reserved_never_negative() { + val utxos = listOf(Utxo(txid="a", vout=0, value=300_000_000L, height=100)) + val reserved = 500_000_000L + // WalletCacheDao.computeSpendableBalanceSat signature: (utxos, reservedSat) -> Long + val spendable = WalletCacheDao.computeSpendableBalanceSat(utxos, reserved) + assertEquals(0L, spendable) + } + @Test fun balance_subtracts_reserved_positive() { /* as in behavior */ } + @Ignore("requires Android Context — implemented by plan 30-02") + @Test fun roundtrip_preserves_utxos_and_timestamp() { /* stub body calling TODO() */ } + } + ``` + Note: `WalletCacheDao.computeSpendableBalanceSat` accepts `(List, Long)` per the inline spec — plan 30-02 MUST honor this signature.

This task replaces each with the real implementation and extends the existing instance methods that touch Keystore. + + 1) `validateMnemonic(input: String): List` — normalize whitespace via `input.trim().split(Regex("\\s+"))`; reject counts not in `setOf(12, 15, 18, 21, 24)` with `IllegalArgumentException("invalid word count: ${words.size}")`; run the existing BIP39 checksum logic on the normalized list (reuse whatever helper currently lives in WalletManager, e.g. `bip39ChecksumValid(words)`; if that helper is private, invoke it via the companion object's internal scope). Return the normalized `List` on success. + + 2) `checkRestorePreconditions(currentBalanceSat: Long, hasBackedUp: Boolean)` — if `currentBalanceSat > 0L && !hasBackedUp` throw `BackupRequiredException("Current wallet has $currentBalanceSat sat and has not been backed up")`. Otherwise return Unit. + + 3) `computeSeedHmacForTest(seed: ByteArray, keyBytes: ByteArray): ByteArray` — use BouncyCastle `HMac(SHA256Digest())`: + ```kotlin + val mac = org.bouncycastle.crypto.macs.HMac(org.bouncycastle.crypto.digests.SHA256Digest()) + mac.init(org.bouncycastle.crypto.params.KeyParameter(keyBytes)) + mac.update(seed, 0, seed.size) + val out = ByteArray(mac.macSize) + mac.doFinal(out, 0) + return out + ``` + Both `computeSeedHmacForTest` and the production `computeSeedHmac(seed)` (instance method) share this logic. The test-only variant takes the key as bytes for determinism; the production variant fetches the HMAC key from the Keystore (see step 5 below). + + 4) `verifySeedHmac(seed: ByteArray, tag: ByteArray, keyBytes: ByteArray)` — compute HMAC and compare with constant-time `java.security.MessageDigest.isEqual(expected, tag)`; on mismatch throw `IntegrityException("seed HMAC mismatch")`. Return Unit on match. + + 5) `wrapKeystoreException(block: () -> T): T` — the inline function catches ONLY `android.security.keystore.KeyPermanentlyInvalidatedException` (and nothing else) and rethrows as `KeystoreInvalidatedException(cause = e)`. All other exceptions pass through unchanged. Because it is inline + reified? No — it is `inline fun ` only (no reified). Place on `WalletManager.Companion` per Wave 0 contract. + + Instance-level changes: + + 6) HMAC key provisioning — introduce a second Keystore AES-GCM key, alias `raventag_wallet_hmac_key` (distinct from the existing alias). Use the same spec as the existing `getOrCreateAndroidKey()` minus any biometric binding (StrongBox when available, `setUnlockedDeviceRequired(true)` on API 28+). This key is used to derive 32 raw key bytes via AES-GCM-encrypting a fixed 32-byte input (or simpler: use HKDF via BouncyCastle — but the RESEARCH A9 / Don't Hand-Roll approach is "use a second Keystore-wrapped AES-GCM key as the HMAC key material"). Implement this way: + - On first use, generate 32 random bytes, AES-GCM-encrypt them with the existing mnemonic Keystore key, and store the ciphertext + IV in the `raventag_wallet` prefs under key `KEY_HMAC_MATERIAL_CT` / `KEY_HMAC_MATERIAL_IV`. + - To compute HMAC, decrypt the stored material to get 32 raw bytes, use them as the BouncyCastle HMAC key, then zero-fill the local `ByteArray` after use. + - Rationale: avoids the trap of exposing a Keystore-bound HMAC key through `javax.crypto.Mac`, which requires a key that can be extracted from the Keystore (AES can't be). BouncyCastle `HMac` takes raw bytes — we bridge through the decrypt step. + + 7) Store/verify HMAC in the existing `storeSeed(seed: ByteArray)` / `getSeed()` / `storeMnemonic(mnemonic: String)` / `getMnemonic()` methods: + - After `encrypt(seed, iv)` produces ciphertext, compute `hmac = computeSeedHmac(seed)` (production variant) and store Base64(hmac) under `KEY_SEED_HMAC`. + - In `getSeed()`, after decrypt, compute HMAC of the plaintext, verifySeedHmac against the stored tag; on mismatch throw `IntegrityException` (no attacker has a usable wallet). + - Same for mnemonic under `KEY_MNEMONIC_HMAC`. + + 8) Wrap every `cipher.doFinal(...)` call site in `wrapKeystoreException { ... }`. Concretely: `getSeed()`, `getMnemonic()`, `storeSeed()` (doFinal on encrypt), `storeMnemonic()`. The wrap converts `KeyPermanentlyInvalidatedException` into `KeystoreInvalidatedException` which the UI surfaces as the "Device security changed" dialog. + + 9) BIP39 whitespace normalization — the existing `validateMnemonic` (if any) at the ~line 818 region per RESEARCH Pitfall 7 must use `input.trim().split(Regex("\\s+"))` before BIP39 processing. The companion shim replaces/wraps the existing instance / companion variant. Concretely: if the existing signature is `fun validateMnemonic(phrase: String): Boolean`, create a new `@JvmStatic fun validateMnemonic(input: String): List` that calls the existing boolean validator on the normalized list and returns the normalized list on success / throws on failure. Retain the boolean variant as a thin shim for any existing callers; update all call sites to use the new list-returning variant where the normalized list is needed. + + 10) `restoreFromMnemonic(phrase: String)` — BEFORE any Keystore rewrite: + - Compute `currentBalanceSat` via `ReservedUtxoDao.sumReservedSat()` + latest cached balance from `WalletCacheDao.readState()?.balanceSat ?: 0L` (or read from SharedPreferences "wallet_poll.poll_rvn_sat" if the reliability DB is not yet initialized). A simple proxy is acceptable: read the last-known balance from the wallet state cache. + - Read `hasBackedUp = prefs.getBoolean("backup_completed", false)`. + - Call `checkRestorePreconditions(currentBalanceSat, hasBackedUp)`. On throw, propagate `BackupRequiredException` to the UI. + - Then validate the phrase via the new `validateMnemonic`; on failure propagate `IllegalArgumentException`. + - Then proceed with the existing restore logic. + + 11) Remove any in-memory mnemonic cache (D-16). AUDIT: search WalletManager.kt for properties of type `String?`, `ByteArray?`, `CharArray?` that hold decrypted mnemonic/seed. Candidates: `private var cachedMnemonic: String? = null`, `private val mnemonicCache: ...`, any `companion object` field that shadows the decrypted value. DELETE them. Ensure every caller re-decrypts via `getMnemonic()` / `getSeed()`. Add acceptance criterion: `! grep -nE '(cachedMnemonic|mnemonicCache|decryptedMnemonic|plaintextSeed|seedCache)' android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt`. + + 12) New instance method `suspend fun revealMnemonicCharsWithBiometric(gate: BiometricGate): CharArray`: + - Build the Cipher in `DECRYPT_MODE` with the Keystore key + stored IV (re-use the existing `decrypt(...)` scaffolding BUT without calling `doFinal` — stop after `cipher.init`). + - Catch `KeyPermanentlyInvalidatedException` at init time via `wrapKeystoreException`. + - Call `gate.decryptWithBiometric(cipher, storedMnemonicCiphertext, R.string.biometricRevealTitle, R.string.biometricRevealSubtitle)` → ByteArray. + - Verify HMAC on the decrypted plaintext. + - Convert `ByteArray` (UTF-8) to `CharArray` via `String(plaintext, Charsets.UTF_8).toCharArray()`. Immediately zero-fill the intermediate `ByteArray` via `Arrays.fill(plaintext, 0)`. + - Return the `CharArray`. **Caller** (MnemonicExporter / UI) is responsible for zero-filling the returned CharArray after display. + + **Em-dash audit** on touched file: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt`. + + + Read `WalletManager.kt` fully (~2102 lines per RESEARCH). Identify these landmarks: + - Existing `encrypt(bytes: ByteArray): Pair` / `decrypt(enc: ByteArray, iv: ByteArray): ByteArray` + - Existing `getOrCreateAndroidKey(): SecretKey` + - Existing `storeSeed`, `getSeed`, `storeMnemonic`, `getMnemonic` methods + - Existing `validateMnemonic` (if present) at ~line 818 + - Existing `restoreFromMnemonic` entry point + - Existing SharedPreferences file name (`raventag_wallet`) and key constants + + Make minimal surgical edits per the behavior section. Rules of engagement: + - Do NOT reorganize existing methods. Add new helpers in a single block at the bottom of the class (and in the companion object block) to minimize diff size. + - Do NOT change existing method signatures except where the behavior section explicitly requires (the new `validateMnemonic` companion is a NEW signature; retain the old boolean one as a thin shim if it exists). + - Do NOT touch `RavencoinTxBuilder.kt` (D-17 hard rule). + + Companion block replacement (replace the five Wave 0 TODOs): + ```kotlin + companion object { + // --- Existing helpers, do not delete --- + // ...

Invoke `handleIncomingTxIntent(intent)` in: + - `onCreate(savedInstanceState: Bundle?)` — after `super.onCreate` and after `setContent { ... }` is composed (use a `LaunchedEffect(Unit)` inside setContent OR call `handleIncomingTxIntent(intent)` AFTER setContent since the navigation state is set up at that point — defer to the existing navigation pattern). + - `override fun onNewIntent(intent: Intent)` — if this override does not yet exist, add it. Call `super.onNewIntent(intent)` then `setIntent(intent)` then `handleIncomingTxIntent(intent)`. + + 4. If MainActivity already handles `TransactionNotificationHelper`'s `VIEW_TRANSACTION` action (it does, per the existing TransactionNotificationHelper deep-link pattern), the SAME handler can route both sources since the action string and extra key are identical. In that case, ensure the handler distinguishes ONLY by the presence of the `txid` extra (incoming path) vs the Phase 20 confirmed-send path (which also uses `txid`). Route both to TransactionDetailsScreen — no behavioral divergence needed. + + Em-dash audit on the touched lines (inspect diff). + + + 1) Locate the block in MainActivity.kt around lines 2447-2461 (per PATTERNS.md line 447) that contains: + ```kotlin + io.raventag.app.worker.NotificationHelper.createChannel(this) + io.raventag.app.worker.TransactionNotificationHelper.createChannel(this) + ``` + + 2) Insert a new line immediately after those two: + ```kotlin + io.raventag.app.worker.IncomingTxNotificationHelper.createChannel(this) + ``` + + 3) Inspect the existing code for any `ACTION_VIEW_TRANSACTION` handler (search for `TransactionNotificationHelper.ACTION_VIEW_TRANSACTION_EXT` OR for a literal `"VIEW_TRANSACTION"` string — MainActivity.kt already contains the Phase 20 deep-link per TransactionNotificationHelper.kt:34). If a handler exists, verify it already reads `EXTRA_TXID`/`"txid"` and routes to TransactionDetailsScreen; then no further change is required (the new IncomingTxNotificationHelper reuses the same action + extra). + + 4) If NO handler exists yet (i.e., Phase 20 plan 20-05 is unchecked on ROADMAP so the deep-link was never wired), add one: + ```kotlin + private fun handleIncomingTxIntent(intent: Intent?) { + if (intent?.action == io.raventag.app.worker.IncomingTxNotificationHelper.ACTION_VIEW_TRANSACTION) { + val txid = intent.getStringExtra(io.raventag.app.worker.IncomingTxNotificationHelper.EXTRA_TXID) + if (!txid.isNullOrBlank()) { + // Route to TransactionDetailsScreen. Use the existing nav state variable + // that WalletScreen uses for the "view tx details" tap. SUMMARY must + // record the exact navigation hook used. + pendingTxNavigation.value = txid + } + } + } + ``` + ...where `pendingTxNavigation` is a `MutableState` declared at class scope (or a reusable existing one). The `setContent { }` block reads this state inside a `LaunchedEffect(pendingTxNavigation.value)` and calls the existing tx-detail navigation hook. + + Then: + ```kotlin + override fun onNewIntent(intent: Intent) { + super.onNewIntent(intent) + setIntent(intent) + handleIncomingTxIntent(intent) + } + ``` + + And call `handleIncomingTxIntent(intent)` at the end of `onCreate` (after `setContent`). + + 5) DO NOT disturb the existing `TransactionNotificationHelper` deep-link (Phase 20 D-04) if already wired; the new helper is strictly additive via the shared action string. + + Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/MainActivity.kt` on the full file.

Reads the wallet's current receive address list (at minimum: the current `currentIndex` address used by ReceiveScreen; optionally the last N addresses — v1 keeps it single-address to match the quantum-resistance model where only `currentIndex` is ever the active receive).

Compute scripthash via the existing `io.raventag.app.wallet.RavencoinPublicNode.addressToScripthash(addr)` helper (or equivalent already used in the worker). + b. Issue a ONE-SHOT RPC call to `blockchain.scripthash.subscribe` (this is functionally a "get current status" call in ElectrumX — the subscription aspect requires a persistent socket which is plan 30-03's domain; the RPC returns the status hash immediately). Call signature: `node.subscribeScripthashRpc(addr)` if plan 30-03 exported that wrapper, else a direct `node.callWithFailover("blockchain.scripthash.subscribe", listOf(scripthash))` followed by `?.takeUnless { it.isJsonNull }?.asString`. + c. Fetch SharedPreferences: `val prevStatus = prefs.getString("last_status_$addr", null)` (file `"wallet_poll"`, same file used by Phase 20 `poll_rvn_sat`). + d. If `currentStatus != prevStatus`: + - Persist new status: `prefs.edit().putString("last_status_$addr", currentStatus).apply()`. + - Re-fetch balance via the existing `RavencoinPublicNode.getBalance(addr)` path. + - Compute delta vs the previously-cached balance (`poll_rvn_sat` key, existing). + - If delta > 0 (new incoming funds): find the newest transaction in `node.getTransactionHistory(addr, limit = 3, offset = 0)` that is NOT already in SharedPreferences key `"last_notified_txid"`; call `IncomingTxNotificationHelper.showIncoming(applicationContext, newTxid, rvnAmount = deltaSat / 1e8, confirmations = newTxEntry.confirmations)`. Save the new `last_notified_txid`. + - On first run (prevStatus == null): do NOT notify — persist the current status and balance; subsequent runs compare against these baselines. Rationale: avoid spamming the user on fresh install with a retroactive "incoming" for any existing balance. + + 3. Resilience policy mirrors the existing worker (WalletPollingWorker.kt:116-122): + - `java.io.IOException` → `Result.retry()`. + - Any other `Exception` → swallow gracefully, `Result.success()`. + - Do NOT surface errors to the user (D-06 is a silent background path). + + 4.

Caller gates rendering; chip itself is unconditional once rendered. + - Card container: `RavenCard` bg, `RoundedCornerShape(8.dp)`, `BorderStroke(1.dp, Color(0xFFF59E0B).copy(alpha = 0.25f))`. + - Inner padding: `horizontal = 8.dp, vertical = 4.dp`. + - Content: Row — `Icons.Default.BatterySaver` 10dp amber `Color(0xFFF59E0B)` + 4dp gap + Text `strings.batterySaverChip` labelSmall amber. + - Tap: does nothing (informational). No clickable modifier. + + 5.4) Extend the existing `ElectrumStatusBadge` (WalletScreen.kt:757-780) with a YELLOW state: + - Drive pill color from `NodeHealthMonitor.stateFlow.collectAsState(initial = ConnectionHealth.GREEN)` — the screen already has a binding; pass the enum in. + - GREEN: existing behavior — AuthenticGreen dot pulsing + text `strings.connectionPillOnline`. + - YELLOW: amber `Color(0xFFF59E0B)` pulsing dot + text `strings.connectionPillReconnecting`. + - RED: NotAuthenticRed STATIC dot (no pulse) + text `strings.connectionPillOffline`. + - Dot pulse animation: reuse the existing animation modifier the badge already has for GREEN; apply to YELLOW; suppress on RED. + - The pill itself must be tappable: `Modifier.clickable { showConnectionSheet = true }`. Accessibility touch target ≥ 48dp (use `Modifier.sizeIn(minHeight = 48.dp)` or equivalent). + + 5.5) Connection pill tap sheet: `@Composable private fun ConnectionPillSheet(onDismiss: () -> Unit)`: + - `ModalBottomSheet(onDismissRequest = onDismiss, containerColor = RavenCard)` from `androidx.compose.material3`. + - Content column, padding 16dp: + - Title bar: Text `strings.connectionPillSheetTitle` titleSmall SemiBold white. + - Section 1: Text `strings.connectionPillCurrentNode` labelSmall RavenMuted + Text `NodeHealthMonitor.currentNode() ?: "—"` bodySmall monospace white. (Note: the dash `—` literal is forbidden per MEMORY. Replace with the explicit fallback string `"(none)"` / `"(nessuno)"` — add a new property `connectionPillNoNode` to AppStrings if needed in Task 4 above; if not already added, executor adds inline literals `"(none)"`/`"(nessuno)"` here and appends the missing string to AppStrings in the same diff.) + - Section 2: Text `strings.connectionPillLastSuccess` labelSmall RavenMuted + Text formatted timestamp from `NodeHealthMonitor.diagnostics()` for `currentNode()`; format via `formatHhMm(...)` or `"—"` equivalent non-emdash fallback. + - Section 3: Text `strings.connectionPillFallbackNodes` labelSmall RavenMuted, then a Column over `NodeHealthMonitor.diagnostics()`.

Visible while `isRefreshing == true`. Colors: `LinearProgressIndicator(color = RavenOrange, trackColor = RavenBorder)`. `height = 2.dp`. Indeterminate. + + 5.7) Disabled Send/Receive when pill is RED: + - Read `val health by NodeHealthMonitor.stateFlow.collectAsState(initial = ConnectionHealth.GREEN)`. + - When `health == ConnectionHealth.RED`: + - Send button: `Modifier.alpha(0.3f)`, text color `RavenMuted`, icon tint `RavenMuted`, `enabled = false` (so the existing onClick does not fire). + - Receive button: same as Send. + - Wrap the button Row with `Modifier.clickable(enabled = true)` that shows a Snackbar using `strings.offlineAllNodesUnreachable` on `NotAuthenticRedBg` container. The clickable MUST be attached to the wrapper, NOT the disabled button, so that even when `enabled = false`, the tap still fires the snackbar. Use `LaunchedEffect` with a `MutableState` that triggers `snackbarHostState.showSnackbar(...)`. + - When `health != ConnectionHealth.RED`: existing Send/Receive behavior unchanged. + + 5.8) 30-second periodic refresh loop, gated by power-save: + - In the WalletScreen `@Composable`, add: + ```kotlin + val context = LocalContext.current + val lifecycleState = ... // existing lifecycle observer pattern + LaunchedEffect(lifecycleState) { + while (true) { + kotlinx.coroutines.delay(30_000L) + val pm = context.getSystemService(android.content.Context.POWER_SERVICE) as android.os.PowerManager + if (!pm.isPowerSaveMode) { + onPeriodicRefresh() // existing refresh hook + } + } + } + ``` + - The scripthash subscription (plan 30-03 SubscriptionManager) stays alive regardless of power-save — its own lifecycle is managed independently by the WalletViewModel / SubscriptionManager start()/stop() paired with foreground state (already wired by plan 30-03). + + 5.9) In-app Snackbar on incoming tx: + - Collect `SubscriptionManager.eventsFlow()` (inject via existing DI or `remember { SubscriptionManager(context) }` used elsewhere in the file). + - On each `ScripthashEvent.StatusChanged`: schedule a re-fetch via the existing refresh hook. AFTER the re-fetch completes, compute `deltaSat = newBalance - previousBalance`. If `deltaSat > 0L`: + - `snackbarHostState.showSnackbar(String.format(strings.incomingTxSnackbar, String.format("%.8f", deltaSat / 1e8)))`. + - Visual: this task keeps the snackbar call; the styled Snackbar host that paints AuthenticGreenBg + AuthenticGreen text + Icons.Default.CallReceived is the screen's top-level `SnackbarHost` configuration. If the existing SnackbarHost does not support per-call theming, add a `customSnackbar` override using `Snackbar(containerColor = AuthenticGreenBg, contentColor = AuthenticGreen, action = null)` with an icon-decorated message body. + + 5.10) Instant-render cached state on open: + - On first composition (`LaunchedEffect(Unit)`): read `WalletCacheDao.readState()` and seed the screen state (balance, tx list) BEFORE any network call. Track `lastRefreshedAt = WalletCacheDao.getLastRefreshedAt()`. Flip `showCachedBanner = true` while a successful refresh has not yet completed. + + Order of composition additions on the screen header column (top-down): + 1. Existing `walletTitle` Text row. + 2. Row: block height + ElectrumStatusBadge (YELLOW-capable) + Refresh icon. + 3. `BatterySaverChip()` (conditional). + 4. `CachedStateBanner(...)` (conditional). + 5. 2dp LinearProgressIndicator (conditional on `isRefreshing`). + 6. BalanceCard (existing, with PendingBalanceLine inserted inside directly under fiat). + 7. Actions Row (Send / Receive with disabled-state wrapper). + 8.

Normalize to a newest-first list: mempool (height == 0) first, then confirmed sorted by height DESC. + - Apply `.drop(offset).take(limit)` client-side. + - Map each entry to `TxHistoryEntry(txid, height, confirmations = (currentHeight - height + 1) if height > 0 else 0, timestamp)`. Skip the expensive per-tx body fetch; pagination does not need tx amounts (they already live in TxHistoryDao once populated). + - If `blockchain.headers.subscribe` is needed for `currentHeight`, use the same batch pattern as the existing `getTransactionHistory`; else reuse any already-cached tip height. + - Wrap the blocking call in `kotlinx.coroutines.withContext(Dispatchers.IO)`. + - On any exception, return `emptyList()` (do NOT rethrow — Load more path must be resilient). + + 2) `object RavencoinTxHistoryMath`: + ```kotlin + object RavencoinTxHistoryMath { + fun computeCycledSat(tx: com.google.gson.JsonObject, changeAddress: String): Long { ... } + fun computeSentSat(tx: com.google.gson.JsonObject, changeAddress: String): Long { ... } + } + ``` + + Semantics: + - `vout` is a `JsonArray` where each element has `value` (RVN as `Double`) and `scriptPubKey.addresses` (a `JsonArray` of `String`). + - `computeCycledSat` sums `value` of outputs whose `scriptPubKey.addresses` contains `changeAddress`, converted from RVN → satoshis (`(value * 1e8).toLong()`). + - `computeSentSat` sums `value` of outputs whose `scriptPubKey.addresses` contains AT LEAST ONE address != `changeAddress`.

`init(context)` idempotent gate (double-checked synchronized lock). + - `nextHealthyNode()`: prunes recent failures by 30s cooldown + skips any host currently in `QuarantineDao.all()` with `quarantinedUntil > now`. + - `reportSuccess(host)` / `reportFailure(host, reason)` / `reportTofuMismatch(host)` update in-memory maps and recompute `_state`. + - `reportTofuMismatch` writes a 1h quarantine row via `QuarantineDao.quarantine(host, 3_600_000L, REASON_TOFU_MISMATCH)`. + - `stateFlow: StateFlow` (read-only) for plan 30-08 pill. + - `diagnostics()` returns per-host `NodeDiagnostic` list for plan 30-08 bottom sheet. + - `currentNode()` returns the most-recently-successful host. +- Recompute rule: + - quarantined == total → RED + - any failure within 30s + at least one fallback free → YELLOW + - any success within 60s → GREEN + - else (cold start / long idle) → YELLOW, promoting to GREEN on first success. + +Also added `val ELECTRUM_SERVERS: List>` with provenance KDoc to both `consumer` and `brand` `AppConfig` objects (flavor-scoped). The `main/` variant was removed to avoid duplicate-class errors. + +### Task 2: RPC + subscription paths routed through NodeHealthMonitor (commit f9067e6) + +`RavencoinPublicNode.kt`: + +- `callWithFailover(method, params)`: replaced the naive `for (server in SERVERS)` loop with a health-aware `repeat(SERVERS.size)` loop that calls `NodeHealthMonitor.nextHealthyNode()` before each attempt, reports success/failure to the monitor, classifies TOFU mismatches via a local `isTofuMismatch(e)` helper, and throws `AllNodesUnreachableException` when `nextHealthyNode()` returns null. +- `callWithFailoverBatch(requests)`: same treatment; returns `List(requests.size) { null }` on all-quarantined (preserves existing caller contract). +- `SERVERS` field now initialized from `AppConfig.ELECTRUM_SERVERS.map { (h, p) -> ElectrumServer(h, p) }` so there is one canonical pool. + +`SubscriptionManager.kt`: + +- `start(addresses)` consults `NodeHealthMonitor.nextHealthyNode()` per attempt, reports outcomes, and emits `ScripthashEvent.AllNodesDown` when all candidates fail. +- `readLoop` and `heartbeatLoop` now report failure (TOFU mismatch or named exception) to `NodeHealthMonitor` before emitting `ConnectionLost` / `PingTimeout`. +- Added `sessionKey(s)` to compute `"host:port"` form used as the monitor key. +- `DEFAULT_SERVERS` companion constant repointed to `AppConfig.ELECTRUM_SERVERS` so any legacy callers share the same pool. +- The existing 60s `pingIntervalMs` already covers D-10 zombie-socket detection (no new heartbeat added). + +`WalletExceptions.kt`: + +- Added `class AllNodesUnreachableException(msg: String = "all ElectrumX nodes quarantined") : RuntimeException(msg)`. + +### Task 3: NetworkModule timeout fix + MainActivity + worker init (commit 46623aa) + +`NetworkModule.kt`: + +- Removed the duplicate `connectTimeout(15, SECONDS)` / `readTimeout(30, SECONDS)` / `writeTimeout(30, SECONDS)` trio that shadowed the intended D-10 values. +- Canonical chain now has exactly one of each (verified: `grep -c 'connectTimeout' == 1`, `grep -c 'readTimeout' == 1`): `connectTimeout(10, SECONDS)`, `readTimeout(20, SECONDS)`, `writeTimeout(20, SECONDS)`. +- Before vs after: + - before: two pairs (lines 69-71 at 10/15/15s + duplicate at 82-84 at 15/30/30s) + - after: single pair at lines 71-73 matching D-10 (10/20/20s) + +`MainActivity.kt`: + +- Added `io.raventag.app.wallet.health.NodeHealthMonitor.init(this)` immediately after `WalletReliabilityDb.init(this)` + `ReservedUtxoDao.pruneOlderThan(...)` (block around line 2460). + +`WalletPollingWorker.kt` + `RebroadcastWorker.kt`: + +- First line of each `doWork()` now calls `NodeHealthMonitor.init(applicationContext)` defensively so a worker spawned before MainActivity has run still has `QuarantineDao` available. + +## Hand-off to Plan 30-08 (WalletScreen UI) + +- `NodeHealthMonitor.stateFlow: StateFlow` is the single StateFlow source for the D-12 connection pill (collect via `ViewModel.collectAsState()`). +- `NodeHealthMonitor.diagnostics()` feeds the "Fallback node list" in the tap-to-open bottom sheet. +- `NodeHealthMonitor.currentNode()` drives the "Current server" row in the bottom sheet. +- `AllNodesUnreachableException` is the thrown signal that plan 30-08 should catch to show the "Offline, all nodes unreachable" snackbar + disable Send/Receive. +- No Compose code was added in this plan (explicit scope boundary). + +## TOFU mismatch detection (identified at execution time) + +`TofuTrustManager.kt` throws a plain `Exception` with message `"Certificate mismatch for : expected , got "`. Both `RavencoinPublicNode` and `SubscriptionManager` classify this via: + +```kotlin +private fun isTofuMismatch(e: Throwable): Boolean { + if (e is java.security.cert.CertificateException) return true + val m = e.message ?: return false + return m.contains("Certificate mismatch", ignoreCase = true) || + m.contains("fingerprint mismatch", ignoreCase = true) || + m.contains("TOFU", ignoreCase = true) +} +``` + +The substring `"Certificate mismatch"` is the actual match in today's code; the other two are forward-compat for potential stack wrappings. + +## QuarantineDao API reconciliation + +Plan text assumed a `QuarantineDao.QuarantinedNode` data class with `upsert / activeAt / pruneExpired`. Reality (per plan 30-02 implementation in `wallet/health/QuarantineDao.kt`): +- `data class Quarantine(val host, val quarantinedUntil, val reason)` +- `fun quarantine(host, durationMillis, reason)` (inserts with `quarantined_until = now + durationMillis`) +- `fun isQuarantined(host)` / `fun clear(host)` / `fun all()` +- No explicit `pruneExpired` (rows age out naturally by the `quarantined_until > now` predicate). + +`NodeHealthMonitor.activeQuarantineHosts(now)` therefore calls `QuarantineDao.all().filter { it.quarantinedUntil > now }` in-memory. With a max of ~4 rows in the pool this is effectively free and matches the monitor's existing SQLite-lazy semantics. + +## Node list policy (RESEARCH Pitfall 8) + +All 4 original hosts retained (`rvn4lyfe.com`, `rvn-dashboard.com`, `162.19.153.65`, `51.222.139.25`). Provenance KDoc added to both flavor `AppConfig` files. `rvn-dashboard.com` is kept despite RESEARCH flagging it LOW confidence: quarantine handles staleness silently without user impact. + +## Flavor considerations + +Because `AppConfig` is a flavor-scoped object (separate files in `src/consumer/` and `src/brand/`), `ELECTRUM_SERVERS` was added to BOTH. Build verified against `:app:assembleConsumerDebug`; the brand variant will pick up the symmetric definition on its next build. + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 3 - Blocker] AppConfig package did not exist in `main/`** +- **Found during:** Task 1 +- **Issue:** Plan assumed `io.raventag.app.config.AppConfig` was a single `main/` source; actual project has per-flavor AppConfig files in `src/consumer/` and `src/brand/` with different booleans per flavor.

[Rule 2 - Correctness] Workers missing NodeHealthMonitor.init** +- **Found during:** Task 3 +- **Issue:** Plan flagged this as a defensive need; confirmed neither worker had any DAO init at doWork entry, risking NPE on cold-start. +- **Fix:** Added `NodeHealthMonitor.init(applicationContext)` as first line of both `WalletPollingWorker.doWork()` and `RebroadcastWorker.doWork()`. +- **Commit:** 46623aa + +## Deferred Issues + +- **Pre-existing em dashes in RavencoinPublicNode.kt** (lines 283, 287, 329 before edits).

The consolidation-centric quantum-resistance model (D-17) is now legible to the user: outgoing transactions clearly separate what left the wallet (Sent, red) from what cycled to a fresh change address (Cycled, green) from the miner fee (Fee, muted). Self-transfers collapse to a single Cycled + Fee line with an Autorenew icon, so pure consolidations are visually distinct from external sends. Incoming rows are preserved exactly as before. + +## What Changed + +### Task 1: RavencoinPublicNode additions (commit 09ae52c) +- `suspend fun getHistoryPaged(address, offset, limit = 20)` wraps `blockchain.scripthash.get_history` with client-side slicing, reuses batch call pattern for tip height + history, returns `emptyList()` on failure (Load more resilient). +- `object RavencoinTxHistoryMath` with pure `computeCycledSat(tx, changeAddress)` and `computeSentSat(tx, changeAddress)` helpers. Safe to unit-test; no network, no storage. Uses `SAT_PER_RVN = 100_000_000L` constant. +- Existing `getTransactionHistory` untouched. + +### Task 2: TxHistoryDao alias (commit 955e1a3) +- Added `fun getPage(offset: Int, limit: Int = 20)` alias wrapping existing `page(limit, offset)`. Matches argument order of `RavencoinPublicNode.getHistoryPaged` and reads naturally at WalletScreen call sites. No schema change. + +### Task 3: AppConfig.EXPLORER_URL (commit 0999a5f) +- Added `const val EXPLORER_URL: String = "https://ravencoin.network/tx/"` to both consumer and brand flavor `AppConfig` files. Same value in both. + +### Task 4: AppStrings EN + IT (commit 8e1c899) +- New strings: `txHistorySentPrefix`, `txHistoryCycledPrefix`, `txHistoryFeePrefix`, `txHistoryLoadMore`, `txHistoryEmptyHeading`, `txHistoryEmptyBody`, `txDetailsViewOnExplorer`, `txHistoryConfirmations`. +- EN and IT variants verbatim from UI-SPEC Copywriting Contract. +- "Fee" kept invariant in IT; separator U+00B7 used; zero U+2014 em dashes. + +### Task 5: WalletScreen TxCard rewrite (commit 0aa07d0) +- Outgoing branch now renders three right-aligned value lines: Sent (NotAuthenticRed, SemiBold, `-` prefix), Cycled (AuthenticGreen, labelSmall), Fee (RavenMuted, labelSmall); 2dp gap between value lines, 6dp before the timestamp/conf row. +- Self-transfer variant (`isSelf == true`): single line `Cycled X RVN · Fee Y RVN` with `Icons.Default.Autorenew` in RavenOrange, no Sent line. +- Incoming branch preserved (single green `+X RVN` line with CallReceived icon). +- Confirmation dot color: red at 0 conf, amber `0xFFF59E0B` at 1-5, AuthenticGreen at >=6 (D-08 verified). +- Load more RavenOrange button wired to `TxHistoryDao.getPage(offset, 20)` with `RavencoinPublicNode.getHistoryPaged` fallback that writes shell rows. +- Empty-state composable renders verbatim EN/IT headings and body copy. + +### Task 6: TransactionDetailsScreen three-value breakdown + explorer (commit 17b967a) +- Reads primary source from `TxHistoryDao.findByTxid(txid)` on IO dispatcher; falls back gracefully when no row is cached. +- Outgoing: three rows with icons (CallMade / Autorenew / Payments) and colored amounts (NotAuthenticRed / AuthenticGreen / RavenMuted). +- Self-transfer: Cycled + Fee only (no Sent). +- Incoming: legacy single-amount layout preserved. +- `View on explorer` OutlinedButton (RavenOrange border + content) calls `Intent.ACTION_VIEW` on `AppConfig.EXPLORER_URL + txid`; `ActivityNotFoundException` swallowed silently per ASVS V7. + +## Commits + +| Task | Name | Commit | +|------|------|--------| +| 1 | RavencoinPublicNode.getHistoryPaged + RavencoinTxHistoryMath | 09ae52c | +| 2 | TxHistoryDao.getPage(offset, limit) alias | 955e1a3 | +| 3 | AppConfig.EXPLORER_URL (consumer + brand) | 0999a5f | +| 4 | AppStrings EN + IT for 3-value row + Load more + empty + explorer | 8e1c899 | +| 5 | WalletScreen TxCard three-value row + Load more + empty state | 0aa07d0 | +| 6 | TransactionDetailsScreen three-value breakdown + View on explorer | 17b967a | + +## Verification + +- `./gradlew :app:assembleConsumerDebug` exits 0. +- `./gradlew :app:assembleBrandDebug` exits 0. +- Em-dash audit across all seven touched files: zero U+2014 occurrences. +- Acceptance grep patterns for each task verified against the final file state. + +## Deviations from Plan + +None.

WalletManager: handle Keystore key rotation for HMAC material (regenerate on AEADBadTagException). MAX-send / consolidation now drain to exactly 0 RVN by detecting sweep mode (amountSat + fee > totalIn) and routing through the builder's existing fee-subtraction branch. Tightened consolidation byte estimate from 250→150 sat per input. Tx history fetch passes the full owned address set (incl. currentIndex+1) so cycled outputs classify as "back to wallet" rather than "sent to others". RavencoinPublicNode: getAddressStatusBatch now bases HAS_OUTGOING on get_balance(asset=true) instead of listunspent (which is RVN-only) — fixes asset-only receives being mis-classified, which had caused discoverCurrentIndex to advance the wallet without any spend. Added getAddressesWithSignificantFunds so the consolidation banner can ignore < 0.001 RVN dust residues. Tx history classification computes cycledSat / sentSat / feeSat from full vin/vout walks. NodeHealthMonitor: GREEN check now takes precedence over YELLOW so a single successful RPC clears the pill even when other hosts had transient failures in the last 30s. Cold-start fallback returns GREEN instead of YELLOW. MainActivity: 30s background heartbeat keeps the ElectrumX pill fresh between refreshes. Cold-start seeds walletInfo + tx history from local cache so the balance/tx sections do not flash zero on resume. Tx history refresh keeps the prior list visible when a transient fetch returns empty. Asset transfer optimistically marks isLoading and waits 3s before re-querying to avoid showing a stale balance during mempool propagation. WalletScreen: ConnectionHealthPill prefixes "ElectrumX · " and drops the 48dp minHeight that was adding empty space. Block height + hashrate persist during refresh. BalanceCard reserves USD/price rows so the card height does not contract on a loading flip. Empty-state cards for assets and transactions stay visible during refresh. Self-transfer tx row shows fee on its own muted line. Txid is clickable to copy the full hash. SendRvnScreen: MAX button now fills the full balance and lets WalletManager subtract the exact fee — wallet ends at 0 RVN. MnemonicBackupScreen: capture revealed buffer at effect launch so the zero-fill on disposal doesn't wipe the buffer that was just installed. Render guard skips the words grid when the buffer has been zero-filled. --- .../main/java/io/raventag/app/MainActivity.kt | 124 +++++++++++++++--- .../app/ui/screens/MnemonicBackupScreen.kt | 12 +- .../raventag/app/ui/screens/SendRvnScreen.kt | 13 +- .../raventag/app/ui/screens/WalletScreen.kt | 103 +++++++++------ .../app/wallet/RavencoinPublicNode.kt | 103 +++++++++++---- .../io/raventag/app/wallet/WalletManager.kt | 75 +++++++---- .../app/wallet/cache/WalletReliabilityDb.kt | 5 +- .../app/wallet/health/NodeHealthMonitor.kt | 10 +- 8 files changed, 333 insertions(+), 112 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index 8db0e94..c876aec 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -60,6 +60,7 @@ import androidx.lifecycle.viewModelScope import kotlinx.coroutines.async import kotlinx.coroutines.awaitAll import kotlinx.coroutines.coroutineScope +import kotlinx.coroutines.delay import kotlinx.coroutines.sync.Semaphore import kotlinx.coroutines.sync.withPermit import io.raventag.app.nfc.NfcCounterCache @@ -732,10 +733,14 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { Pair(assetsDeferred.await(), rvnDeferred.await()) } -

Added parseAssetPayload that extracts the asset name + raw amount from rvnt/rvnq/rvno/rvnr markers, and incoming/outgoing tags so TxHistoryEntry now carries an assetName and assetAmount. Hidden-incoming fallback marks scripthash-history hits that the parser could not otherwise classify. WalletManager: corrected getAddressStatusBatch decision (RECEIVE_ONLY vs HAS_OUTGOING) — previously listunspent-based check mis-classified asset-only addresses as HAS_OUTGOING and caused discoverCurrentIndex to advance the wallet on receive. Tightened consolidation byte estimate and amount formula so old addresses end at zero satoshis. MainActivity: optimistic asset removal on transfer (decrements balance, removes when zero). Snapshot pre-send balance and reject obviously-wrong post-send refreshes (>1.05× pre-balance) to prevent the temporary "double balance" mempool race. Tx history fetch uses ownedAddresses set spanning currentIndex+1. WalletScreen: TxCard incoming and outgoing branches now show "+N ROOT / SUB # UNIQUE" multi-line for asset transfers; self-transfer branch surfaces the asset name when present (asset cycling).

Added clearAll() helpers in those DAOs. MainActivity.deleteWallet resets ownedAssets, txHistory and needsConsolidation so a restore-after-delete no longer flashes the "Replace current wallet?" gate against stale state. initWallet seeds walletInfo, txHistory and ownedAssets synchronously from on-disk cache before the first render, so cold start shows the last-known balance / list instead of zero / empty. BalanceCard shows the loading copy when isLoading and balance == 0 (fresh install with no cache). WalletCacheDao.writeBalanceSat persists the freshly fetched balance after each successful refresh; loadWalletBalance{,Internal} call it. TxHistoryDao upserts the deduped page after each refresh. loadOwnedAssetsInternal now runs the IPFS enrichment pipeline (asset meta batch + per-asset enrichWithIpfsData with semaphore). Previously only the non-internal loadOwnedAssets ran enrichment, so the brand build (which goes through the parallel refresh path) never showed image previews. Tx history initial display caps at txHistoryPageSize (now 20). Load more fetches the next page via offset; total reflects the full dataset so the button stays visible until exhausted. --- .../main/java/io/raventag/app/MainActivity.kt | 143 ++++++++++++++++-- .../raventag/app/ui/screens/WalletScreen.kt | 51 +++++-- .../io/raventag/app/wallet/WalletManager.kt | 10 ++ .../app/wallet/cache/ReservedUtxoDao.kt | 5 + .../raventag/app/wallet/cache/TxHistoryDao.kt | 5 + .../app/wallet/cache/WalletCacheDao.kt | 23 +++ 6 files changed, 215 insertions(+), 22 deletions(-) diff --git a/android/app/src/main/java/io/raventag/app/MainActivity.kt b/android/app/src/main/java/io/raventag/app/MainActivity.kt index dab03e1..cf31951 100644 --- a/android/app/src/main/java/io/raventag/app/MainActivity.kt +++ b/android/app/src/main/java/io/raventag/app/MainActivity.kt @@ -644,7 +644,7 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { var txHistoryLoadedCount by mutableStateOf(0) /** Page size for loading more transactions. */ - private val txHistoryPageSize = 15 + private val txHistoryPageSize = 20 // ── Asset portfolio ─────────────────────────────────────────────────────── @@ -871,11 +871,13 @@ class MainViewModel(application: Application) : AndroidViewModel(application) { ) // Avoid wiping the visible list when a transient network error - // returns an empty result during a refresh. + // returns an empty result during a refresh.

IPFS failures allow retry without restarting the entire form. +- **D-03:** Known error categories to classify: insufficient funds, duplicate asset name, RPC node unreachable/connection refused, RPC timeout, fee estimation failure, IPFS gateway down, IPFS auth expired, and invalid address format. + +### Pre-issuance Validation +- **D-04:** Full pre-flight validation in three sequential steps on submit: + 1. Wallet balance check: verify wallet has enough RVN for issuance fee (500/100/5 RVN per asset type) + estimated network fee. Show inline warning if insufficient. + 2. Asset name uniqueness check via backend API call. + 3. IPFS metadata upload. +- **D-05:** Multi-step progress indicator shown on submit button tap: "Caricamento IPFS..." → "Verifica disponibilita'..." → "Emissione in corso..." → "Conferma in corso...". Each step shows success/failure before advancing. +- **D-06:** IPFS upload triggered on submit (not as separate button, not auto on image select). Sequential steps with clear per-step status. Uploaded CID preserved for retry. + +### Issuance Retry Policy +- **D-07:** Auto-retry only safe errors with 5x exponential backoff (consistent with Phase 20 D-02/D-06). Safe errors: connection failures, DNS resolution failures, IPFS upload failures. These carry no double-spend risk since no tx was broadcast. +- **D-08:** On RPC timeout: do NOT re-broadcast. Instead query tx status via `getrawtransaction`. If tx landed on-chain → treat as success. If tx not found → prompt user to retry manually. This prevents accidental double-spend of the issuance fee. +- **D-09:** RPC rejections (duplicate asset name, insufficient funds, invalid parameters) → never auto-retry. Show classified error with suggested action (e.g., "Fondi insufficienti — invia RVN al wallet brand e riprova"). + +### Post-issuance Confirmation UX +- **D-10:** Show confirmation progress after successful issuance: "Pending..." → "N/6 conferme" → "Confermato". Consistent with Phase 30 D-08 receive confirmation pattern. Auto-dismiss banner after 6 confirmations. +- **D-11:** Txid in result banner is tappable. Opens block explorer at `https://ravencoin.network/tx/{txid}`. +- **D-12:** Issued asset appears in transaction history after next WalletScreen sync (Phase 30 D-01 periodic poll). +- **D-13:** Combined "Issue + Write Tag" flow: progress indicator includes NFC programming as distinct step: "Caricamento IPFS..." → "Emissione in corso..." → "Programmazione tag NFC..." → "Conferma (N/6)". Tag write step has its own progress since user must hold phone to tag. + +### Critical Constraints (non-negotiable) +- **C-01:** Unique token issuance flow (issue + NFC tag programming) must remain intact. All error handling changes are additive layers on top of the existing working flow. Do not restructure the `onIssueUniqueAndWriteTag` path. +- **C-02:** Asset emission currently works. Changes to error/retry path must not alter the successful issuance code path. Add try/catch classification and pre-flight checks without changing `WalletManager.issueAssetLocal()` or `RpcClient` internals. +- **C-03:** The `IssueAssetScreen` composable API (callback signatures) is the boundary.

Skip. + +## Common Pitfalls + +### Pitfall 1: Silent error in revokeAsset (pre-existing bug) +**What goes wrong:** `revokeAsset` at MainActivity.kt line 1714-1729 calls `am.revokeAsset(...)` but discards the returned `AssetOperationResult` and unconditionally sets `issueSuccess = true`. Result: revocations that fail at the backend level (e.g., auth error, asset not found) appear as successful to the user. +**Root cause:** The `withContext(Dispatchers.IO)` block returns the `AssetOperationResult` but the result is never captured. +**How to avoid:** Capture the result: `val result = withContext(Dispatchers.IO) { am.revokeAsset(BurnParams(...)) }` then check `result.success`. +**Warning signs:** Assets that remain unrevoked after UI shows "revocato". + +### Pitfall 2: Over-classification of error messages +**What goes wrong:** Exception messages from different sources (ElectrumX, WalletManager, RavencoinTxBuilder, AssetManager) are unreliable for pattern matching. Messages may change when ElectrumX server software is updated or when Ravencoin Core changes. +**Why it happens:** The project uses exception message string matching (e.g., `msg.contains("insufficient funds")`) rather than typed exception classes. +**How to avoid:** Keep classification as a single `when` block with fallback to raw message. Log the original message for debugging. Accept that some errors will fall through to the default case. +**Warning signs:** New ElectrumX versions causing misclassified errors. + +### Pitfall 3: Race condition in multi-step state +**What goes wrong:** If the user dismisses the screen or navigates away while a step is in progress, the coroutine continues running and may update stale state. +**Why it happens:** `viewModelScope.launch` is not cancelled on navigation; IssueStep state lives in the ViewModel. +**How to avoid:** Use `clearIssueResult()` existing pattern to reset step state on navigation. Check `isActive` at each step boundary. +**Warning signs:** "Ghost" step progress shown after returning to the screen. + +### Pitfall 4: Double submission during multi-step flow +**What goes wrong:** The user taps Submit during Step 1 (IPFS upload), and the step takes long enough that the user taps Submit again. +**Why it happens:** The step indicator replaces the submit button, but if button enablement is not properly gated, re-taps can occur. +**How to avoid:** Gate the submit button on `issueStep is IssueStep.Idle`. Once any step is in progress, the button must be disabled. The `isLoading` parameter already does this, but the step state must also gate it. +**Warning signs:** Multiple simultaneous IPFS uploads or issuance RPC calls. + +### Pitfall 5: Polling for confirmation after processIssueAndWrite +**What goes wrong:** The `processIssueAndWrite` flow is a `suspend` function that returns `Result`. The confirmation polling needs to run after the combined flow completes, but `onTagTapped` only sets `writeTagStep = SUCCESS` or `ERROR`. +**Why it happens:** The post-issuance confirmation phase is not part of the existing flow; it's additive. +**How to avoid:** After `processIssueAndWrite` returns success, start a separate coroutine for confirmation polling. Do not integrate it into the processIssueAndWrite function itself. +**Warning signs:** Confirmation progress never appears after combined flow. + +## Code Examples + +### Current revokeAsset bug (must fix) +```kotlin +// MainActivity.kt lines 1714-1729 +fun revokeAsset(assetName: String, reason: String, adminKey: String) { + val am = AssetManager(context = getApplication(), adminKeyStorage = adminKeyStorage!!) + viewModelScope.launch { + issueLoading = true + try { + withContext(Dispatchers.IO) { + am.revokeAsset(BurnParams(assetName, reason = reason, burnOnChain = false)) + } + issueSuccess = true // BUG: always true + issueResult = "Asset $assetName revocato" + } catch (e: Throwable) { + issueSuccess = false; issueResult = e.message ?: "Revoca fallita" + } finally { issueLoading = false } + } +} +``` + +### Current generic catch pattern in issuance callbacks +```kotlin +// MainActivity.kt line 1625-1627 (issueRootAsset example) +try { + val txid = withContext(Dispatchers.IO) { + wm.issueAssetLocal(assetName, qty.toDouble(), toAddress, units = 0, reissuable = reissuable, ipfsHash = ipfsHash) + } + issueSuccess = true + issueResult = s.issueRootSuccess.replace("%1", assetName).replace("%2", "${txid.take(16)}...") +} catch (e: Throwable) { + issueSuccess = false; issueResult = getStrings().issueFailed // Generic, no classification +} +``` + +### Existing retryWithBackoff usage pattern +Source: `android/app/src/main/java/io/raventag/app/utils/RetryUtils.kt` +```kotlin +RetryUtils.retryWithBackoff(maxAttempts = 5, initialDelayMs = 1000L, backoffMultiplier = 2.0) { + networkCall() // Will retry on SocketTimeout, UnknownHost, transient IOException +} +``` + +### Existing isTransientError classification +Source: `android/app/src/main/java/io/raventag/app/utils/RetryUtils.kt` +```kotlin +fun isTransientError(e: Exception): Boolean = when (e) { + is SocketTimeoutException -> true + is UnknownHostException -> true + is IOException -> { + val msg = e.message?.lowercase() ?: return false + msg.contains("timeout") || msg.contains("connection") || msg.contains("network") || msg.contains("temporary") + } + else -> false +} +``` + +### Burn fee constants for balance check +Source: `android/app/src/main/java/io/raventag/app/wallet/RavencoinTxBuilder.kt` +```kotlin +const val BURN_ROOT_SAT = 50_000_000_000L // 500 RVN +const val BURN_SUB_SAT = 10_000_000_000L // 100 RVN +const val BURN_UNIQUE_SAT = 500_000_000L // 5 RVN +``` + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| Generic `issueFailed` string | Classified error with specific message + action | Phase 40 | Users get actionable guidance instead of "emissione fallita" | +| Single `isLoading` boolean | Multi-step sealed class with per-step status | Phase 40 | Users see which step failed and can act on it | +| No retry on issuance failure | Safe-error retry with 5x exp backoff + timeout check | Phase 40 | Transient failures auto-recover without user action | +| `revokeAsset` always succeeds | `revokeAsset` checks AssetOperationResult | Phase 40 | Silent revocation failures surface to user | + +**Deprecated/outdated:** +- `revokeAsset` result discard (MainActivity.kt line 1721): confirmed bug via code review; fix is in scope since it's a silent failure elimination + +## Assumptions Log + +| # | Claim | Section | Risk if Wrong | +|---|-------|---------|---------------| +| A1 | Exception message string matching is reliable enough for the 8 known categories | Standard Stack | ElectrumX/Ravencoin error messages vary by version; misclassification falls back to raw message which is acceptable | +| A2 | Backend does not have a dedicated name-uniqueness API endpoint | Pre-issuance Validation | Pre-issuance validation must use ownedAssets list from frontend cache.

This is acceptable as a best-effort pre-check | + +## Open Questions + +1. **Backend name uniqueness endpoint?** + - What we know: `AssetManager` has `issueAsset`/`issueSubAsset`/`issueUniqueToken` but no dedicated "check name exists" endpoint. The ownedAssets list in the frontend cache is the closest proxy. + - What's unclear: Whether the backend provides an endpoint like `/api/brand/check-name` or if we should just check against the local cache. + - Recommendation: Use local ownedAssets list for pre-flight check (ownedAssets contains all brand assets). Consider adding a backend endpoint in Phase 50 if needed. + +2. **Exact error strings from WalletManager.issueAssetLocal()?** + - What we know: Uses `error("...")` (IllegalStateException), `require(...)` (IllegalArgumentException), and exceptions from RavencoinTxBuilder and RavencoinPublicNode. + - What's unclear: The full set of possible error messages without running the code against all failure modes. + - Recommendation: Use broad message pattern matching (.contains) in the classification function. Add logging (`Log.e`) of the original message for debugging. Fall through to raw message for unclassified errors. + +3. **getrawtransaction availability?** + - What we know: `RavencoinPublicNode` uses ElectrumX protocol, which provides `blockchain.transaction.get`. This is available via `callElectrumRawOrNull`. + - What's unclear: Whether the verbose=true format returns a `height` field for all tx states (mempool vs confirmed). + - Recommendation: In timeout handling, check if `blockchain.transaction.get` returns a result. If height > 0, tx is confirmed. If height == null or result is error, tx not found. + +## Validation Architecture + +### Test Framework +| Property | Value | +|----------|-------| +| Framework | JUnit 4 + Robolectric (Android project) | +| Config file | Not checked -- Phase 30 used @Ignore for Robolectric-dependent tests | +| Quick run command | `./gradlew :app:testDebugUnitTest -x lint` | +| Full suite command | `./gradlew :app:testDebugUnitTest` | + +### Phase Requirements to Test Map +| Req ID | Behavior | Test Type | Automated Command | File Exists? | +|--------|----------|-----------|-------------------|-------------| +| D-01 | Error classification maps known exception messages to correct string keys | unit | `./gradlew :app:testDebugUnitTest --tests "*IssueErrorClassificationTest*"` | Will be Wave 0 | +| D-07 | retryWithBackoff wraps transient errors correctly | unit | Reuse existing RetryUtils tests | Existing tests | +| D-10 | Confirmation polling logic | unit | `./gradlew :app:testDebugUnitTest --tests "*ConfirmationTest*"` | Wave 0 | + +### Sampling Rate +- **Per task commit:** Not applicable (no existing test pattern for per-commit runs observed) +- **Per wave merge:** `./gradlew :app:testDebugUnitTest` +- **Phase gate:** Full test suite green before verify + +### Wave 0 Gaps +- [ ] `IssueErrorClassificationTest.kt` -- unit tests for `classifyIssuanceError` function (pure logic, no Android deps) +- [ ] `ConfirmationPollingTest.kt` -- unit tests for confirmation tracking logic (pure logic) +- [ ] No UI test detected for the composable step indicator (Jetpack Compose UI tests may need Compose Test dependency -- skip for Phase 40, manual verification only) + +## Environment Availability + +| Dependency | Required By | Available | Version | Fallback | +|------------|------------|-----------|---------|----------| +| Android SDK 34 | Compile target | ✓ | 34 | — | +| Kotlin 1.9 | Language | ✓ | 1.9.x | — | +| Gradle | Build system | ✓ | 8.x | — | +| OkHttp | HTTP client | ✓ | 4.x | — | +| Bouncy Castle | Crypto | ✓ | 1.77 | — | +| ElectrumX server | Broadcast/confirmation check | Runtime | — | Fallback server list, fail-closed | + +**Missing dependencies with no fallback:** None -- all dependencies are already in the project. + +## Sources + +### Primary (HIGH confidence) +- Codebase inspection of `MainActivity.kt`, `IssueAssetScreen.kt`, `AssetManager.kt`, `WalletManager.kt`, `AppStrings.kt`, `RetryUtils.kt`, `RavencoinPublicNode.kt`, `RavencoinTxBuilder.kt`, `TransactionNotificationHelper.kt` + +### Secondary (MEDIUM confidence) +- `40-CONTEXT.md` — Phase decisions and constraints (D-01 through D-13, C-01 through C-03) +- `.planning/STATE.md` — Project progress and recent decisions +- `.planning/PROJECT.md` — Milestone focus and requirements + +## Metadata + +**Confidence breakdown:** +- Standard stack: HIGH - All patterns and libraries verified in codebase +- Architecture: HIGH - Existing flows well understood, changes are additive +- Pitfalls: HIGH - revokeAsset bug confirmed via code read, other patterns observed in existing code + +**Research date:** 2026-04-25 +**Valid until:** 2026-05-25 (codebase is stable, no expected breaking changes) From fbd3d93a9dd9e9dbfc01163eb09433dd9dcbd3e7 Mon Sep 17 00:00:00 2001 From: Alessandro Nocentini Date: Sat, 25 Apr 2026 19:51:36 +0200 Subject: [PATCH 144/181] docs(40): UI design contract for asset emission UX Defines the full visual and interaction contract for Phase 40: - Multi-step progress indicator (Pattern 1): vertical timeline with pending/in-progress/completed/failed states per step - Error classification banner (Pattern 2): two-line classified error messages with suggested actions - Pre-issuance validation warning (Pattern 3): inline amber card for balance/name checks before submit - Confirmation tracking N/6 (Pattern 4): polling badge with auto-dismiss at 6 confirmations - Combined flow NFC step (Pattern 5): embedded NFC programming step in the progress indicator for Issue+Write tag flow - Tappable txid in result banner linking to ravencoin.network explorer - RevokeAsset bug fix: capture AssetOperationResult instead of discard - 24 new AppStrings.kt keys for Italian error messages and step labels - All copy, spacing, typography, color tokens, and interaction contracts --- .../phases/40-asset-emission-ux/40-UI-SPEC.md | 597 ++++++++++++++++++ 1 file changed, 597 insertions(+) create mode 100644 .planning/phases/40-asset-emission-ux/40-UI-SPEC.md diff --git a/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md b/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md new file mode 100644 index 0000000..e811eba --- /dev/null +++ b/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md @@ -0,0 +1,597 @@ +--- +phase: 40 +slug: asset-emission-ux +status: draft +shadcn_initialized: false +preset: none +created: 2026-04-25 +--- + +# Phase 40: UI Design Contract + +> Visual and interaction contract for Phase 40 Asset Emission UX.

No third-party block vetting required. + +--- + +## Key Visual Patterns (Phase 40 specific) + +### Pattern 1: Multi-Step Progress Indicator + +**Purpose:** Replaces the simple `isLoading` boolean-driven spinner with a per-step visual timeline showing the user exactly where in the issuance flow they are and which step succeeded or failed. + +**Location:** Between the form fields area and the submit button in `IssueAssetScreen.kt`. The progress indicator replaces the submit button entirely while steps are running. When no step is active (Idle), neither the indicator nor the submit button is affected. + +**Layout specification:** +``` ++------------------------------------------+ +| | +| [Step 1] [Caricamento IPFS...] | Completed: green check + muted text +| | +| | | Vertical connector line, 2dp wide, RavenBorder +| | +| [Step 2] [Verifica disponibilita'] | Current: Orange spinner + orange bold text +| | +| | | +| | +| [Step 3] [Verifica nome...] | Pending: hollow circle + muted text +| | +| | | +| | +| [Step 4] [Emissione in corso...] | Pending (shown based on flow stage) +| | ++------------------------------------------+ +``` + +**Step row specification:** +- Outer container: `Row` with `Modifier.fillMaxWidth()`, vertical center alignment. +- Left icon column: fixed 28dp width, `Arrangement.Center` vertically. Icon size: 20dp. + - Pending: `Box` with 8dp circle hole (`RavenBorder`, 2dp `BorderStroke`), no fill. + - In progress: `CircularProgressIndicator` 20dp, 2dp stroke, `RavenOrange`. + - Completed: `Icons.Default.CheckCircle` 20dp, `AuthenticGreen`. + - Failed: `Icons.Default.Error` 20dp, `NotAuthenticRed`. +- Right label column: `Column`, `weight(1f)`, padding start 8dp. + - Step name text: `bodySmall` (14sp Normal), color depends on state (see Color section). + - Failed state shows error message as second line: `labelSmall` (12sp), `NotAuthenticRed`, below step name with 2dp gap. +- Vertical connector line: `Box` with `Modifier.width(2.dp).height(12dp).background(RavenBorder)`, positioned between step rows, aligned to the center of the icon column. Only shown between non-terminal steps. + +**Step row vertical gap:** 12dp between rows, plus 12dp after the connector. + +**When to show:** The indicator is shown only while `issueStep` is not `Idle`. It replaces the `SubmitButton` composable during active steps. After the flow completes (success or failure), the indicator is replaced by the result banner (existing pattern). The user cannot submit again until they navigate away and come back (or the `clearIssueResult()` pattern clears the state). + +**Animation:** +- Current step icon: the `CircularProgressIndicator` provides its own indeterminate animation (existing Material 3 behavior). +- Step transitions: no animation between step state changes beyond the icon swap. Immediate visual update is preferred over animated transitions per the "responsive feedback" requirement. + +**Detailed logic for step display:** +- The indicator shows ALL steps that will be executed in the current flow, not just the remaining ones. Completed steps remain visible with green checkmarks so the user can see overall progress. +- The combined "Issue + Write Tag" flow shows the `NFC_PROGRAMMING` step between `ISSUING` and `CONFIRMING`. The standalone issuance flow skips this step. +- The `BALANCE_CHECK` and `NAME_CHECK` steps are shown as a single row "Verifica disponibilita'..." (combined label) since they run sequentially and fast. The inner progress distinguishes them but the UI shows one row. + +### Pattern 2: Error Classification Banner (extending result banner) + +**Purpose:** Shows the classified error message (from Research Pattern 1) in the existing result banner at `IssueAssetScreen.kt:256-269`, with added suggested action text. + +**Extends existing pattern:** +The existing result banner (lines 256-269) is a `Card` with `AuthenticGreenBg` or `NotAuthenticRedBg`, icon, and single-line message. Phase 40 extends this: + +- Error state: two-line text inside the banner (primary error message + suggested action on second line). +- Both lines use `bodySmall` (14sp Normal). Primary line: `NotAuthenticRed`. Suggestion line: `RavenMuted` (to de-emphasize the action text vs the error). +- For IPFS errors, the suggestion line is replaced by a "Riprova" (Retry) inline button: `TextButton` with `RavenOrange` text, `contentPadding = PaddingValues(horizontal = 8.dp, vertical = 2.dp)`, no background. Positioned to the right of the error text or as a separate row below. +- For timeout errors, the suggestion line includes the txid (if known) with "Verifica su explorer" link. + +**Txid tappable link (D-11):** +When the result banner shows a successful issuance with a txid, the txid text in the banner must be tappable: +- Txid displayed in `FontFamily.Monospace`, `bodySmall`, `AuthenticGreen`. +- Clickable area: the txid text only (not the entire banner). +- On tap: open `Intent(Intent.ACTION_VIEW, Uri.parse("https://ravencoin.network/tx/{txid}"))`. +- Visual indicator: underline on the txid portion, `clickable` modifier, no color change (stay AuthenticGreen). +- If no txid is available (e.g., error state), no clickable element. + +### Pattern 3: Pre-Issuance Validation Warning (inline) + +**Purpose:** Shows inline warning below the form fields when pre-submit validation detects a condition that will cause issuance failure. Displayed BEFORE the user taps submit (as opposed to error classification which is post-submit). + +**Location:** Between the form fields and the submit button. Same position as the result banner. + +**Behavior:** +- Balance check: shown when the user has entered form fields but wallet balance is below the required threshold. NOT shown while fields are empty. +- Name uniqueness check: shown when the typed asset name already exists in `ownedAssets`. Re-evaluated on every keystroke to the asset name field. + +**Display specification:** +- Container: `RavenCard` background, `RoundedCornerShape(12.dp)`. +- Border: 1dp amber `0xFFF59E0B.copy(alpha = 0.4f)`. +- Inner padding: 12dp. +- Icon: `Icons.Default.Warning` 16dp, amber `0xFFF59E0B`. +- Text: `bodySmall` (14sp Normal), amber `0xFFF59E0B`, single line or two lines. +- Margin below the warning: 12dp (gap before submit button). +- The warning is auto-dismissed when the condition is resolved (balance topped up, name changed). +- Only one warning shown at a time (balance check takes priority over name check). + +### Pattern 4: Confirmation Progress (N/6) + +**Purpose:** After successful issuance (txid known), show the confirmation counter in the result banner area while the ViewModel polls for confirmations (D-10). + +**Location:** The existing result banner position (`IssueAssetScreen.kt:256-269`). The success result banner remains visible, and the confirmation status is shown as an additional row beneath the success message. + +**Display specification:** +``` ++------------------------------------------+ +| Check Token OUTFIT/BAG02#SN0001 emesso | Success message (existing) +| | +| Schedule Conferma (3/6) | New confirmation row ++------------------------------------------+ +``` + +- Confirmation row: padding start 36dp (aligned to text start after the 20dp icon), `bodySmall` (14sp Normal). +- Icon: `Icons.Default.Schedule` 14dp, amber `0xFFF59E0B` for 0-5 confirmations; `Icons.Default.CheckCircle` 14dp, `AuthenticGreen` for 6/6. +- Text format: `"Conferma (N/6)"` in `bodySmall`. Color: amber for 0-5, `AuthenticGreen` for 6/6. +- Auto-dismiss (D-10): when 6/6 is reached, the entire result banner + confirmation row fades out (animate to alpha 0 over 500ms, then the parent composable hides via `resultSuccess = null`). This is the only animated transition in Phase 40. +- Polling interval: 30 seconds (as specified in Research Pattern 4). +- The confirmation progress only appears on the IssueAssetScreen. The user can navigate away and the confirmation continues in the background via `viewModelScope.launch`. + +### Pattern 5: Button Combined Flow Progress (D-13) + +**Purpose:** The combined "Issue + Write Tag" flow (`processIssueAndWrite` in MainActivity.kt) has its own 7-step internal flow. The multi-step progress indicator adapts to show these steps. + +**Layout:** Same vertical timeline as Pattern 1, but with `NFC_PROGRAMMING` step injected between `ISSUING` and `CONFIRMING`: + +1. `IPFS_UPLOAD` -- "Caricamento IPFS..." +2. `BALANCE_CHECK` -- "Verifica disponibilita'..." +3. `NAME_CHECK` -- "Verifica nome..." +4. `ISSUING` -- "Emissione in corso..." +5. `NFC_PROGRAMMING` -- "Programmazione tag NFC..." (unique to combined flow) +6. `CONFIRMING` -- "Conferma (N/6)" + +The `NFC_PROGRAMMING` step shows the same waiting/progress state as the existing `WriteTagScreen.kt` `PROCESSING` step but displayed inline in the step indicator rather than on a separate screen. This replaces the separate `WriteTagScreen` navigation for the combined flow; the user stays on `IssueAssetScreen` throughout. + +**NFC tap waiting state within progress indicator:** +When `NFC_PROGRAMMING` becomes the active step, the indicator row switches to a special state: +- Icon: `Icons.Default.NearMe` 20dp, `RavenOrange`, with an infinite scale animation (0.92 to 1.08, 900ms, FastOutSlowInEasing, RepeatMode.Reverse) -- matching the existing `NfcWaitStep` pattern from `WriteTagScreen.kt:167-176`. +- Label: "Avvicina il tag NFC al telefono" in `bodySmall`, `RavenOrange`. +- Subtitle: "Tieni il telefono vicino fino al termine." in `labelSmall`, `RavenMuted`. +- This state persists until the NFC tag is detected or the user cancels. + +--- + +## Loading UI Patterns (inherited from Phase 20/30, extended) + +### Button Loading Spinner +Unchanged from Phase 20 UI-SPEC: 20.dp white `CircularProgressIndicator`, 2.dp stroke, disabled button at 30% opacity. Still used for the submit button before the multi-step progress indicator activates. Once the multi-step indicator is shown, the button is replaced entirely. + +### Multi-Step Indicator Spinner +Each step's in-progress state uses a 20.dp `CircularProgressIndicator`, 2.dp stroke, `RavenOrange`. This is the same spinner as the button loading spinner, just relocated to the step icon column. + +### Full-screen loading +Not used in Phase 40. The issuance flow is interactive enough that a full-screen overlay would block the user from seeing step progress. + +### Confirmation polling progress +Indeterminate: no linear progress bar. The confirmation row shows `N/6` counter as the primary progress communication (Pattern 4 above). + +### IPFS retry +When IPFS upload fails during the multi-step flow (D-02): +- The `IPFS_UPLOAD` step shows a red X and the error message. +- Below the step label, a "Riprova" (Retry) inline `TextButton` appears: `RavenOrange` text, no border, no background, 8dp padding. +- Tapping retry re-executes only the IPFS upload (not the entire pre-flight sequence). The previously uploaded CID is NOT discarded; the retry uses the same metadata. +- After 3 consecutive IPFS failures, the retry button is replaced with "Vai a Impostazioni" (Go to Settings) that opens the Settings screen to check IPFS credentials. +- This differs from auto-retry (D-07) which happens silently in the background for transient network errors. The inline retry button is for non-transient IPFS failures (auth expired, gateway down). + +--- + +## Interaction Contracts + +### Standard Issuance Flow + +**Pre-conditions:** +- User has filled out the form fields for the selected mode (ROOT, SUB, UNIQUE_TOKEN, REVOKE, UNREVOKE). +- Admin key is configured in Settings (for issue/revoke operations). +- Wallet exists and has been restored. + +**Interaction sequence:** +1. User fills form fields and optionally uploads an image via `ImagePickerButton`. +2. Real-time pre-issuance validation checks run on field input (balance check debounced 500ms after last change, name check on every keystroke). Warnings appear inline if conditions are met. +3. User taps the submit button (`btnIssueRoot`, `btnIssueSub`, `btnIssueUnique`, `btnIssueAndWrite`, `btnRevoke`, `btnUnrevoke`). +4. The submit button text is replaced by the multi-step progress indicator (Pattern 1). +5. Step 1 -- `IPFS_UPLOAD`: If an image is attached, metadata is uploaded to IPFS. Green checkmark on success; red X + "Riprova" on failure. +6. Step 2 -- `BALANCE_CHECK`: Wallet balance is checked against burn fee + network fee. Amber warning shown if insufficient. If insufficient, the step shows failure but the user can still proceed (the on-chain RPC will fail with its own classified error). +7. Step 3 -- `NAME_CHECK`: Asset name uniqueness checked against `ownedAssets`. Amber warning if duplicate name exists. If duplicate, the step shows failure; user must change the name. +8. Step 4 -- `ISSUING`: RPC issuance is broadcast via `WalletManager.issueAssetLocal()`. On success: green checkmark, txid captured. On failure: classified error message (Pattern 2) with suggested action. Safe errors auto-retry via `retryWithBackoff` (D-07); non-transient errors show the classification banner. +9. Step 5 -- `CONFIRMING`: Post-issuance confirmation polling (Pattern 4). Shows "Pending..." progressing to "N/6 conferme". Auto-dismiss at 6/6. +10. Result banner shows final status with tappable txid (D-11). The multi-step progress indicator is replaced by the result banner. + +**On failure at any step:** +- The step shows a red X with the error message. +- A "Riprova" button (for IPFS) or suggestion text (for classified RPC errors) is shown. +- Other completed steps remain visible with green checkmarks so the user knows what succeeded. +- The user can navigate away to fix the issue (e.g., add RVN to wallet, change IPFS settings). + +### Combined "Issue + Write Tag" Flow (D-13) + +**Pre-conditions:** +- Same as standard issuance flow, but `onIssueUniqueAndWriteTag` callback is non-null. +- NFC is enabled on the device. + +**Interaction sequence:** +1-4. Steps 1-4 (IPFS, Balance, Name, Issuing) are identical to the standard flow. +5. Step 5 -- `NFC_PROGRAMMING`: The step indicator shows "Programmazione tag NFC..." with the NFC wait animation (Pattern 5). The phone's NFC dispatch activates. User holds phone to tag. +6. Tag is detected, keys are derived, NDEF URL is written, chip is registered on backend. +7. Step 6 -- `CONFIRMING`: Confirmation polling begins (same as standard flow). +8. Result banner shows combined success with txid and registration status. + +**On NFC programming failure:** +- The `NFC_PROGRAMMING` step shows a red X with the error message from the tag operation. +- "Riprova" button re-enters the NFC wait state (step resets to NFC_PROGRAMMING in-progress). +- The asset issuance from step 4 is already on-chain and NOT rolled back. The user can retry NFC programming or navigate away and program the tag later via the standalone write-tag flow. + +### Revoke Flow (bug fix) + +**Interaction sequence (unchanged, but result handling fixed):** +1. User selects REVOKE mode, enters asset name and reason. +2. Taps "Revoca asset" (NotAuthenticRed button). +3. Button shows loading spinner (existing behavior). +4. `viewModelScope.launch` calls `am.revokeAsset(...)`. +5. **Fixed behavior (D-09 implicit):** The `AssetOperationResult` returned by `am.revokeAsset()` is captured. If `result.success` is true: green banner "Asset revocato". If false: red banner with the error from `result.error`. +6. **Previous bug:** The result was discarded and success was always set to true. + +### Timeout Handling Flow (D-08) + +**Interaction sequence (after RPC timeout):** +1. Step 4 (`ISSUING`) shows a timeout error: amber warning "Richiesta timeout. Verifica su explorer." +2. The ViewModel does NOT re-broadcast. Instead, it calls `RavencoinPublicNode.callElectrumRawOrNull("blockchain.transaction.get", listOf(txid, true))` to check if the tx was mined. +3. If the txid is known and on-chain: the flow advances to step 5 (confirmation tracking) treating it as success. +4. If txid is unknown: the flow shows the timeout error with "Riprova manualmente" text. No auto-retry. + +### Confirmation Polling Cancel + +If the user navigates away from `IssueAssetScreen` during confirmation polling: +1.

This is available via `callElectrumRawOrNull`. - What's unclear: Whether the verbose=true format returns a `height` field for all tx states (mempool vs confirmed). - - Recommendation: In timeout handling, check if `blockchain.transaction.get` returns a result.

Five targeted fixes: unhandledRejection handler, parallel asset hierarchy fetching, listassets pagination, request_logs cleanup, and safe SQLite backup via .backup() API.

On crash: log error, attempt graceful shutdown (close HTTP server, close SQLite connection), then `process.exit(1)`. Docker restarts cleanly. +- **D-02:** Keep plain-text `console.error` logging. No migration to structured JSON logging. + +### Asset Hierarchy Parallelism +- **D-03:** Replace sequential `for` loop in `getAssetHierarchy` with `Promise.allSettled()`. Failed sub-asset branches return a `partial: true` flag and `errors: [...]` array in the response. Successful branches still return data. +- **D-04:** Limit concurrent sub-asset RPC calls to 5-10 via a simple semaphore or chunked batching. Prevents flooding the Ravencoin RPC node. + +### listassets Pagination +- **D-05:** Add optional `?limit=N&offset=M` query params. Default limit remains 200 (current behavior). Omitting params preserves existing behavior — fully backward-compatible. +- **D-06:** Response format: envelope with metadata. `{assets: [...], total: N, limit: N, offset: N, hasMore: boolean}`. Existing clients ignore unknown fields. + +### Cleanup Strategy +- **D-07:** `request_logs` cleanup via `setInterval` every 24h in the Node.js process. Retention: 30 days. Run once at startup too. +- **D-08:** `nfc_counters` table: NEVER cleaned up. It is the anti-replay mechanism for NTAG 424 DNA tag verification. Removing counters would allow tag replay attacks. + +### SQLite Backup +- **D-09:** Replace raw file copy in backup flow with `better-sqlite3` `.backup()` API. This produces a consistent snapshot under WAL mode, safe under concurrent writes. +- **D-10:** Backup frequency: every 6 hours. Retention: keep last 3 backups (18-hour rotating window). Encrypt output with `openssl enc` (preserve existing encryption pattern). +- **D-11:** Update `docker-compose.yml` backup container to use `sqlite3` CLI `.backup` command (the container doesn't have Node.js). The in-process Node.js backup (D-09) handles runtime; the compose backup is an additional safety layer. + +### CLI Database Explorer +- **D-12:** Add `npm run db:explore` script. Opens a read-only REPL with pre-built commands: `.assets` (list registered assets), `.brands` (list brands), `.revoked` (list revoked assets), `.stats` (table row counts). Uses `better-sqlite3` in read-only mode to protect the permanent database. +- **D-13:** CLI tool is read-only — no write operations, no schema changes. The database is permanent and must never be altered or deleted by tooling. + +### Critical Constraints +- **C-01:** Existing SQLite database is permanent. No migration may delete or alter existing tables in a backward-incompatible way. New columns must be additive (ALTER TABLE ADD COLUMN with DEFAULT). +- **C-02:** All API changes must be backward-compatible with existing Android app versions (consumer + brand flavors) and the Next.js frontend.

Validation Architecture + +### What Must Be Verified +1. **unhandledRejection**: Process does not crash on unhandled promise rejection — handler logs and exits gracefully +2. **Parallel hierarchy**: Concurrent sub-asset fetches complete faster than sequential. Partial failures return partial data. +3. **Pagination**: Hierarchy endpoint accepts limit/offset. Response includes metadata envelope. Omitting params preserves default behavior. +4. **Cleanup**: request_logs older than 30 days are deleted. nfc_counters is untouched. +5. **Backup**: `.backup()` API produces consistent snapshot. Docker backup container uses `sqlite3` CLI. +6. **CLI**: `npm run db:explore` opens read-only REPL. Pre-built commands work. + +### Nyquist Dimensions +- **Dimension 1 (Goal achievement):** Backend is stable — no unhandled rejection crashes, hierarchy responses are fast, logs don't grow unbounded, backups are safe +- **Dimension 2 (Requirement coverage):** All 5 requirements from ROADMAP.md addressed +- **Dimension 3 (Context fidelity):** All 13 D-0x decisions and 3 C-0x constraints honored +- **Dimension 4 (Code correctness):** TypeScript compiles, existing API responses unchanged for default params +- **Dimension 5 (Backward compatibility):** All API changes are additive.

The core invariant is that all cryptographic verification can run client-side with no trust in the server. - -## Components - -### Backend (Node.js/Express) -- REST API server serving verification, asset management, brand, admin, and registry endpoints -- SQLite database (via `better-sqlite3`) for caching, revocation, counters, chip/brand registries, and audit logs -- Ravencoin RPC client for on-chain asset operations -- ElectrumX client for UTXO queries and raw transaction broadcasting (on-device signing flow) -- IPFS integration for asset metadata - -### Frontend (Next.js 14, App Router) -- Web NFC scanning via NDEFReader (Web NFC API, Chrome Android only) -- Thin API proxy routes forwarding to backend -- Verification result display with revocation status -- Brand management UI (issue, revoke, dashboard) -- Internationalization via i18n translations - -### Android (Kotlin/Compose) -- Two product flavors: `brand` (full management, `IS_BRAND_APP=true`) and `consumer` (verify-only, `IS_BRAND_APP=false`) -- NFC reading via `NfcAdapter` + NDEF URL parsing -- On-device BIP44 HD wallet (m/44'/175'/0'/0/0) with BIP39 mnemonic, secured via Android Keystore AES-GCM -- Asset issuance via on-device transaction signing + ElectrumX broadcast -- SUN verification via Bouncy Castle AES-CMAC - -## SUN Verification Pipeline (NTAG 424 DNA, NXP AN12196) - -Three-step process: -1. **AES-CBC decrypt** of the encrypted UID/counter field using `SUN_ENC_KEY` -2. **Session MAC key derivation**: CMAC-based SV2 derivation from `SUN_MAC_KEY`, decrypted UID, and counter -3. **Truncated SDMMAC verify**: NXP truncation `CMAC(sessionKey, enc_data)[even_bytes][:4]` = 4 bytes = 8 hex chars, constant-time comparison - -## Verification Modes - -| Endpoint | Mode | Key exposure | -|---|---|---| -| `GET /api/verify/tag/:uid` | Brand-sovereign | No keys sent to client; server performs full verify | -| `POST /api/verify/full` | Trustless | Caller supplies `encKey` + `macKey`; server is stateless verifier | -| `POST /api/verify/sun` | Operator-protected | Operator holds keys; low-level SUN verify | - -## Authentication Tiers - -- **Public**: `GET /api/assets/:name/revocation`, all verify endpoints -- **Operator** (`OPERATOR_KEY` or `ADMIN_KEY` header `X-Api-Key`): brand routes, asset queries -- **Admin only** (`ADMIN_KEY` header `X-Admin-Key`): admin routes, registry management - -## Key Derivation - -Per-slot AES-128 ECB key derivation from master key: -``` -slotKey = AES128_ECB(masterKey, [slot || uid || padding]) -``` -Slots 0x00-0x03 for ENC, MAC, and auxiliary keys. - -## Privacy Identifier - -``` -nfc_pub_id = SHA-256(tag_uid || BRAND_SALT) -``` -The salt is never stored on-chain, making the on-chain identifier unlinkable without brand cooperation. - -## Data Flows - -### NFC Tap -> Verification -1.

In the brand flavor, `MainActivity.kt:2113` instantiates `AssetManager(adminKey = BuildConfig.ADMIN_KEY)`. If the default empty string `""` is shipped, all admin calls silently fail; if a real key is compiled in, it is extractable from the APK by decompiling. -- Files: `android/app/build.gradle.kts` (line: `buildConfigField("String", "ADMIN_KEY", "\"\"")`), `android/app/src/main/java/io/raventag/app/MainActivity.kt:2113` -- Current mitigation: The brand app also stores the admin key in EncryptedSharedPreferences (set from Settings UI), and most brand flows use the key entered at runtime. The `BuildConfig.ADMIN_KEY` path is a secondary fallback that is only exercised when no key has been saved to prefs yet. -- Recommendation: Remove the `BuildConfig.ADMIN_KEY` field entirely; always require the key from EncryptedSharedPreferences and surface a clear onboarding error when it is absent. - -**ElectrumX TLS: `rejectUnauthorized: false` in production:** -- Risk: The ElectrumX client in `backend/src/services/electrumx.ts:189` disables certificate validation for all TLS connections (`rejectUnauthorized: false`, `checkServerIdentity: () => undefined`). The only protection is in-memory TOFU pinning, which resets on every process restart. A MITM can present any certificate on the first connection after a restart and permanently pin a fraudulent fingerprint. -- Files: `backend/src/services/electrumx.ts:186-205` -- Impact: An attacker controlling the network path after a backend restart could feed false asset data or suppress revocation lookups. -- Fix approach: Pin known SHA-256 fingerprints of the Ravencoin public ElectrumX servers in a config file and validate against them, or use `rejectUnauthorized: true` when the server uses a CA-signed certificate. - -**TOFU cert cache is in-process and non-persistent:** -- Risk: `certCache` in `backend/src/services/electrumx.ts:124` is a plain JS `Map`, cleared on every Node.js restart. Any orchestrated restart (container restart, deploy) resets all pinned fingerprints, leaving the first post-restart connection window unprotected. -- Files: `backend/src/services/electrumx.ts:124` -- Fix approach: Persist fingerprints to the SQLite database so they survive restarts. - -**Admin key sent over HTTP in development (no TLS enforcement):** -- Risk: `backend/src/index.ts:74-78` allows `http://localhost:*` CORS origins in development. No mechanism prevents brand app operators from pointing the Android app at a plain-HTTP backend URL. Admin key and per-chip AES keys would travel in cleartext. -- Files: `backend/src/index.ts:74-78`, `android/app/src/main/java/io/raventag/app/config/AppConfig.kt:17` -- Severity: Low in production (enforced by reverse proxy), real in misconfigured deployments. - -**AES keys from `derive-chip-key` transmitted in HTTP response body:** -- Risk: `POST /api/brand/derive-chip-key` returns all four per-chip AES-128 keys in the response JSON (`backend/src/routes/brand.ts:212-219`). Any logging layer (proxy, WAF, request logging) that captures response bodies would capture active cryptographic keys. -- Files: `backend/src/routes/brand.ts:185-220` -- Mitigation in place: The request logger (`backend/src/middleware/logger.ts`) does not log response bodies. The route is behind adminLimiter (5 req/min) and requireAdminKey. -- Recommendation: Verify that no upstream proxy or CDN logs response bodies for this path. - -**`SELECT *` in admin list endpoints leaks schema details:** -- Risk: `backend/src/routes/admin.ts:78`, `backend/src/middleware/cache.ts:129`, `backend/src/middleware/cache.ts:249` use `SELECT *`. If new columns are added to these tables (e.g., internal notes), they are exposed without an explicit choice. -- Files: `backend/src/routes/admin.ts:78`, `backend/src/middleware/cache.ts:129,249` -- Fix: Use explicit column lists in all admin SELECT queries. - ---- - -## Performance - -**Sequential N+1 RPC calls in `getAssetHierarchy`:** -- Problem: `backend/src/services/ravencoin.ts:220-232` fetches sub-assets with `listSubAssets(parentAsset)`, then iterates over all results with a `for` loop calling `listSubAssets(sub)` sequentially. A parent with N sub-assets generates N+1 serial RPC/ElectrumX calls. -- Files: `backend/src/services/ravencoin.ts:224-230` -- Impact: For a brand with 50 sub-assets, a single `/api/assets/:name/hierarchy` request makes 51 sequential network calls, each potentially up to 12s (ElectrumX timeout). Response latency scales linearly with the asset tree depth. -- Fix approach: Replace the sequential `for` loop with `Promise.all(subAssets.map(...))`. - -**`listassets` cap at 200 sub-assets per call:** -- Problem: `backend/src/services/ravencoin.ts:186-189` limits each `listassets` call to 200 results. Brands with more than 200 sub-assets or unique tokens will silently receive a truncated list with no indication of truncation. -- Files: `backend/src/services/ravencoin.ts:186-189` -- Fix approach: Implement pagination using the offset parameter, or document the 200-item limit explicitly in API responses. - -**SQLite `request_logs` table grows unboundedly at runtime:** -- Problem: Migration 6 in `backend/src/middleware/migrations.ts:132-140` deletes logs older than 30 days only once at migration time. There is no periodic cleanup job. Under sustained traffic the table grows indefinitely, eventually degrading all SQLite query performance (the table shares the same WAL file as revocation and counter checks). -- Files: `backend/src/middleware/migrations.ts:133-140`, `backend/src/middleware/logger.ts:55-62` -- Fix approach: Add a SQLite trigger on `request_logs` INSERT that deletes rows older than 30 days, or implement a periodic Worker in the Node.js process using `setInterval`. - -**`nfc_counters` table has no retention policy:** -- Problem: Each unique chip that has ever been scanned creates a permanent row in `nfc_counters`. There is no cleanup logic anywhere in the codebase. In a high-volume deployment the table grows indefinitely and every scan performs an `INSERT OR REPLACE` that writes through to WAL. -- Files: `backend/src/middleware/cache.ts:109-119`, `backend/src/middleware/migrations.ts:63-68` -- Fix approach: Delete `nfc_counters` rows for chips whose asset is revoked or when the chip is de-registered. Optionally add a TTL-based sweep for chips not seen in > 1 year. - -**`idCounter` in ElectrumX client is not concurrent-safe:** -- Problem: `backend/src/services/electrumx.ts:131` uses a module-level `let idCounter = 1` that is incremented with `idCounter++`. Under concurrent requests this can produce duplicate IDs, causing response misrouting on a shared socket. (In practice each request opens its own socket, so the impact is low, but the pattern is fragile.) -- Files: `backend/src/services/electrumx.ts:131,166-167` -- Fix: Use `Math.random()` or a proper UUID for JSON-RPC IDs, or document that each call uses its own socket and the counter is only for correlation within that call. - -**Android `enrichWithIpfsData` is a blocking synchronous call on a worker thread:** -- Problem: `android/app/src/main/java/io/raventag/app/ravencoin/RpcClient.kt:246-308` uses OkHttp's blocking `execute()` and iterates over multiple gateway URLs sequentially. This is called from a coroutine but is not itself a suspend function, so it blocks the thread for up to `N_gateways * 30s` per asset. -- Files: `android/app/src/main/java/io/raventag/app/ravencoin/RpcClient.kt:246-308` -- Fix: Convert to a suspend function with `withContext(Dispatchers.IO)` and try gateway URLs in parallel with `select { }`. - ---- - -## Technical Debt - -**`registered_tags` table is labeled "legacy" but still has active endpoints:** -- Problem: `backend/src/routes/admin.ts` comments describe `registered_tags` as a "legacy store" but three active admin endpoints (`POST /api/admin/register-tag`, `GET /api/admin/tags`, `DELETE /api/admin/tags/:nfcPubId`) still read/write it. The newer `chip_registry` table in `backend/src/routes/brand.ts` is the intended replacement. The legacy table creates two parallel registration systems that can diverge. -- Files: `backend/src/routes/admin.ts`, `backend/src/middleware/migrations.ts:46-52` -- Fix approach: Document that `registered_tags` is deprecated and should not be used for new integrations; eventually migrate remaining callers to `chip_registry`. - -**`ensureTable()` in registry routes duplicates migrations:** -- Problem: `backend/src/routes/registry.ts:43-51` contains a `CREATE TABLE IF NOT EXISTS brand_registry` statement run on every request to protect against the table not existing yet. This duplicates the same DDL in Migration 2. The pattern indicates uncertainty about whether migrations are always applied before routes are hit. -- Files: `backend/src/routes/registry.ts:43-51`, `backend/src/middleware/migrations.ts:78-85` -- Fix: Remove the `ensureTable()` guard now that migrations run at startup before routes are mounted. - -**Duplicate `connectTimeout`/`readTimeout` in Android `NetworkModule`:** -- Problem: `android/app/src/main/java/io/raventag/app/network/NetworkModule.kt:82-84` sets `connectTimeout` and `readTimeout` a second time inside `buildClient`, overriding the values set on lines 69-71. The effective timeouts are 15s connect / 30s read, but the first set (10s/15s) is silently discarded. -- Files: `android/app/src/main/java/io/raventag/app/network/NetworkModule.kt:67-86` -- Fix: Remove the duplicate timeout calls on lines 82-84. - -**`consolidate_fix.kt` file in project root is uncommitted scratch code:** -- Problem: A file `consolidate_fix.kt` exists at the repository root and appears in `git status` as untracked. Its purpose is unclear and it should either be committed into a proper location or deleted. -- Files: `/consolidate_fix.kt` - -**Comment typo in `index.ts` (duplicated line):** -- Problem: `backend/src/index.ts:10-11` contains the comment "Mount all API route groups under /api/*" duplicated on consecutive lines. -- Files: `backend/src/index.ts:10` -- Impact: Cosmetic only. - ---- - -## Dependency Risks - -**`better-sqlite3` v9 requires native compilation:** -- Risk: `better-sqlite3` uses a native Node.js addon. Any Node.js major version upgrade, Alpine Linux base image change, or ARM/x86 cross-compilation will require a native rebuild. A mismatch causes an immediate startup crash. The Dockerfile uses `node:20-alpine`; if the base image is updated to Node 22 without rebuilding, the pre-built addon will refuse to load. -- Files: `backend/package.json` (`"better-sqlite3": "^9.4.3"`), `backend/Dockerfile` -- Mitigation: The multi-stage Dockerfile ensures the addon is built in the same environment it runs in. Keep the `node:20-alpine` pin explicit and bump it intentionally. - -**No `package-lock.json` test coverage:** -- Risk: Backend has no test suite (no Jest, Mocha, or similar in `backend/package.json`). Dependency upgrades (e.g., `axios`, `zod`) are not regression-tested. The `^` version pins in `package.json` allow minor/patch upgrades that could introduce breaking changes silently. -- Files: `backend/package.json` - -**Bouncy Castle included as a compile-time dependency in Android:** -- Risk: `android/app/build.gradle.kts` depends on `bouncy.castle` for AES-CMAC, ECDSA, and BIP32 operations. Bouncy Castle is a large library and has had historical CVEs (mostly in its TLS stack, not AES). The app uses only the crypto primitives, not the TLS stack. No version is pinned in the concern list without checking `libs.versions.toml`. -- Files: `android/app/build.gradle.kts` - -**`axios` v1.6.7 in backend is not the latest patch:** -- Risk: `axios` 1.6.x had a SSRF-related advisory (GHSA-wf5p-g6vw-rhxx) in some configurations. The IPFS fetch code in `backend/src/services/ipfs.ts` uses axios for external network calls. The SSRF mitigation is applied at the application layer (`ipfsUriToHttp`), but upgrading to the latest patch is low-risk. -- Files: `backend/package.json` (`"axios": "^1.6.7"`), `backend/src/services/ipfs.ts` - ---- - -## Operational - -**SQLite hot backup may produce a corrupt file under write load:** -- Risk: The backup container in `docker-compose.yml` (lines 39-54) reads `/data/raventag.db` with `openssl enc` (a raw file copy). SQLite WAL mode does not guarantee a consistent copy of a file read this way while writes are in progress. The result is a backup that may not be a valid SQLite database. -- Files: `docker-compose.yml:39-54` -- Fix approach: Replace the raw file copy with `sqlite3 /data/raventag.db ".backup /backups/raventag_${TIMESTAMP}.db"` (SQLite's online backup API), which is safe under concurrent writes, then encrypt the output. - -**No structured error logging or log aggregation:** -- Problem: All backend errors are logged to stdout with `console.error('[tag]', err)`. There is no structured JSON logging, no log level filtering, and no integration with an external log aggregator. Debugging production issues requires direct access to container logs. -- Files: `backend/src/middleware/logger.ts`, all route files using `console.error` -- Fix approach: Replace `console.error` with a structured logger (e.g., `pino`) that emits JSON with severity, timestamp, request ID, and stack trace. - -**No process-level unhandledRejection handler:** -- Problem: `backend/src/index.ts` does not register a `process.on('unhandledRejection', ...)` handler. An unhandled promise rejection in Node.js 20+ terminates the process. The Express global error handler on line 225 only catches synchronous errors thrown inside route handlers; async errors from outside the request lifecycle (e.g., ElectrumX background operations) are uncaught. -- Files: `backend/src/index.ts` -- Fix: Add `process.on('unhandledRejection', (reason) => console.error('[Fatal]', reason))` at startup. - -**Single Docker container = single point of failure:** -- Problem: The entire backend runs as one Node.js process in one container with a single SQLite file. There is no horizontal scaling path, no read replica, and no failover. A backend restart causes brief downtime for all scan verification requests. -- Files: `docker-compose.yml` -- Impact: Acceptable for an open-source self-hosted protocol, but relevant for brands expecting high availability. - -**No health check on the frontend container:** -- Problem: `docker-compose.yml` defines a `healthcheck` only for the `backend` service. The `frontend` service (if defined) has no health check. The backup container depends on `backend` being healthy, but if the frontend is down the compose stack still reports healthy. -- Files: `docker-compose.yml` - -**`request_logs` IP field stores raw X-Forwarded-For header value:** -- Problem: `backend/src/middleware/logger.ts:37-38` reads the first value from `X-Forwarded-For` to populate the `ip` column. This value is controlled by the client if the server is not behind a trusted reverse proxy. The trust is set globally with `app.set('trust proxy', 1)` (`index.ts:63`), which trusts exactly one proxy hop. If the deployment has zero or more than one proxy hop, the stored IP will be wrong or spoofed. -- Files: `backend/src/middleware/logger.ts:37-38`, `backend/src/index.ts:63` -- Fix: Document the required `trust proxy` setting in `.env.example` and verify against the actual deployment topology. - ---- - -## Data Integrity - -**Soft revocation is per-instance: multi-backend deployments produce inconsistent results:** -- Problem: Revocation state lives entirely in the local SQLite database (`revoked_assets` table). If two instances of the backend are deployed behind a load balancer (or even with a blue-green deploy), a revocation applied to instance A is not visible to instance B until the database is shared or replicated. A scanner hitting the unrevoked instance would see an AUTHENTIC result for a revoked asset. -- Files: `backend/src/middleware/cache.ts:74-82`, `backend/src/routes/brand.ts:54-70` -- Fix approach: For multi-instance deployments, mount the same SQLite file via a shared NFS/EFS volume, or migrate to PostgreSQL. Document this single-instance constraint in the deployment guide. - -**`issued_at` field in `asset_emissions` is user-supplied:** -- Problem: `backend/src/routes/registry.ts:140` uses `issued_at || new Date().toISOString()`. The client can supply any `issued_at` value, including timestamps in the past or future, without validation. The field is used for ordering in the public emissions list. -- Files: `backend/src/routes/registry.ts:140` -- Fix: Ignore the client-supplied `issued_at` and always use `new Date().toISOString()` server-side, or validate that the value is a well-formed ISO 8601 date within an acceptable window. - -**Asset emission notifications auto-register brands without verification:** -- Problem: `backend/src/routes/registry.ts:151-157` auto-registers the root part of a notified asset name as a brand in `brand_registry` without any ownership verification. Any caller who knows a valid `txid` for a root asset can cause that asset name to appear in the public brand directory. -- Files: `backend/src/routes/registry.ts:151-157` -- Impact: The public brand list can be polluted with brand names that are not operated by the notifier. -- Fix approach: Require the brand to be explicitly registered via the admin-protected `POST /api/registry/register` endpoint, and remove the auto-registration from the notify path. - ---- - -*Concerns audit: 2026-04-13* diff --git a/.planning/codebase/CONVENTIONS.md b/.planning/codebase/CONVENTIONS.md deleted file mode 100644 index 328cc54..0000000 --- a/.planning/codebase/CONVENTIONS.md +++ /dev/null @@ -1,139 +0,0 @@ -# Coding Conventions - -**Analysis Date:** 2026-04-13 - -## Naming Patterns - -**Files:** -- TypeScript backend: `camelCase.ts` (e.g., `ntag424.ts`, `ravencoin.ts`, `cache.ts`) -- TypeScript frontend components: `PascalCase.tsx` (e.g., `CookieBanner.tsx`, `LanguageSelector.tsx`) -- Next.js pages: `page.tsx` in directory-named routes (App Router pattern) -- Kotlin Android: `PascalCase.kt` (e.g., `SunVerifier.kt`, `WalletManager.kt`, `NfcReader.kt`) -- Test files (Android): `PascalCaseTest.kt` co-located under `src/test/` mirroring `src/main/` package path - -**Functions:** -- TypeScript: `camelCase` for all exported and internal functions (`computeNfcPubId`, `verifySunMessage`, `requireAdminKey`, `isAssetRevoked`) -- Kotlin: `camelCase` methods inside `object` singletons or classes; top-level helpers also `camelCase` -- React components: `PascalCase` default exports matching the filename (`export default function HomePage()`, `export default function AdminPage()`) - -**Variables:** -- TypeScript/JS: `camelCase` (`tagUid`, `sdmMacKey`, `adminKey`, `sessionMacKey`) -- Kotlin: `camelCase` (`sdmEncKey`, `sdmMacKey`, `tagUid`, `testPrivKey`) -- Constants: `SCREAMING_SNAKE_CASE` for module-level config values (`BURN_ROOT_SAT`, `DB_PATH`, `API`, `LIMIT`) - -**Types / Interfaces:** -- TypeScript: `PascalCase` interfaces and type aliases (`SunVerifyResult`, `RegisteredBrand`, `RevokedAsset`) -- Exported schemas from Zod: `camelCaseSchema` naming (`assetNameSchema`, `sunVerifyRequestSchema`) -- Inferred TypeScript types from Zod: `PascalCase` (`type AssetName = z.infer`) -- Kotlin data classes: `PascalCase` (`SunVerifyResult`, `Utxo`) - -## Code Style - -**Formatting:** -- No Prettier config present; formatting is implicit from TypeScript compiler strictness -- Indentation: 2 spaces in TypeScript/TSX throughout backend and frontend -- Indentation: 4 spaces in Kotlin -- Single quotes for string literals in TypeScript; double quotes in Kotlin and JSX attributes -- Trailing commas used in multi-line TypeScript object/function argument lists - -**Linting:** -- Backend: ESLint via `"lint": "eslint src --ext .ts"` in `backend/package.json`; no config file detected (uses defaults) -- Frontend: Next.js built-in ESLint via `"lint": "next lint"` -- TypeScript strict mode enabled in `backend/tsconfig.json` (`"strict": true`) -- `esModuleInterop: true`, `forceConsistentCasingInFileNames: true`, `skipLibCheck: true` - -## Import Organization - -**TypeScript backend order (observed pattern):** -1.

-**Frontend pattern:** -- `fetch` calls are wrapped in `.then(r => r.ok ? r.json() : null).catch(() => {})` for non-critical UI data -- State for user-facing messages uses `{ ok: boolean; text: string } | null` pattern (e.g., `revokeMsg`, `brandMsg`) -

-## Comments - -**When to Comment:** -- File-level JSDoc block on every module explaining purpose, cryptographic context, and security notes (all reviewed files follow this pattern) -- Function-level JSDoc on every exported function with `@param`, `@returns`, and inline security/protocol notes -- Inline comments explain non-obvious algorithmic steps (e.g., RFC 4493 CMAC steps, NXP AN12196 table references) -- No commented-out code observed - -**JSDoc/TSDoc:** -- All exported TypeScript functions have full JSDoc (`/** ... */`) with `@param`, `@returns` -- Internal (non-exported) helper functions have shorter docstrings or inline comments -- Kotlin: KDoc (`/** ... */`) on exported `object` methods and `data class` properties -

- @Test(expected = IllegalArgumentException::class) - fun `buildAndSign with corrupted recipient address checksum throws`() { ... } -} -``` - -**Key patterns:** -- Test method names use backtick syntax for readable English descriptions -- Tests are grouped by behavior topic with inline section comments (`// ── base58Decode checksum fix tests`) -- No `@Before`/`@After` setup; each test is self-contained -- Lazy properties (`by lazy`) used for expensive shared test data that depends on other lazy values - -## Mocking - -**Framework:** None (no Mockito or MockK dependency detected) - -**Patterns:** -- Tests use independently implemented reference functions (not the class under test) to generate expected values and valid test vectors -- Test vectors are computed from first principles (standard Java crypto APIs + BouncyCastle) so the test verifies correctness against an independent implementation, not against itself - -```kotlin -// Pattern: independent reference implementation to build test vectors -private fun buildSunVector( - sdmEncKey: ByteArray, - sdmMacKey: ByteArray, - uid: ByteArray, - counter: Int -): Pair { -

-**What to Mock:** -- Not applicable; tests use real crypto implementations to verify cryptographic correctness - -**What NOT to Mock:** -- Crypto primitives: always use real AES/CMAC for test vector generation; mocking would defeat the purpose -

-**Priority:** -- `backend/src/utils/crypto.ts`: High. Core crypto primitives with no test coverage; bugs here break the entire verification chain -- `backend/src/services/ntag424.ts`: High. SUN verification pipeline; backend equivalent of the tested `SunVerifier.kt` -- `backend/src/middleware/cache.ts`: Medium. Replay detection and revocation logic are security-critical -- `android/wallet/WalletManager.kt`: Medium.

AdminKeyStorage Class (New) -- **Location**: `android/app/src/main/java/io/raventag/app/security/AdminKeyStorage.kt` -- **Purpose**: Secure wrapper for admin key using EncryptedSharedPreferences -- **Encryption**: AES-256-GCM via Android Keystore -- **API**: `getAdminKey()`, `setAdminKey()`, `hasAdminKey()`, `clearAdminKey()` -- **Security**: Prevents extraction from APK (unlike BuildConfig which is extractable via strings/JADX) - -### 2. AssetManager Migration -- **Constructor change**: Now accepts `Context` and `AdminKeyStorage` instead of `adminKey: String` -- **Admin key access**: Uses computed property that reads from encrypted storage -- **Error handling**: Throws `IllegalStateException` if admin key not configured (fail-safe) -- **Security**: No longer relies on hardcoded or BuildConfig admin key - -### 3. MainViewModel Validation -- **Added**: `validateAdminKey()` suspend function using OkHttp -- **Endpoint**: `/api/admin/validate-key` (or existing admin endpoints) -- **Status tracking**: Updates `adminKeyStatus` (UNKNOWN, CHECKING, VALID, INVALID, WRONG_TYPE) -- **Existing**: `AdminKeyStatus` enum class and `adminKeyStatus` state variable already existed - -### 4. Settings Screen UI -- **New section**: Admin API Key input after Kubo node URL, before Language picker -- **Components**: `SectionLabelWithAdminStatus`, `SettingsTextField` (password field), `SettingsSaveButton` -- **Validation**: Status chip shows key verification result (checking, valid, invalid, wrong type) -- **Security**: Password field masks input to prevent shoulder surfing - -### 5. MainActivity Wiring -- **AdminKeyStorage**: Created as property, initialized before AssetManager -- **AssetManager**: Instantiated with `AdminKeyStorage` instead of `BuildConfig.ADMIN_KEY` -- **SettingsScreen**: Added `currentAdminKey`, `onAdminKeySave`, `adminKeyStatus` parameters -- **Save flow**: Validates key against backend before persisting to encrypted storage -- **Auto-check**: LaunchedEffect checks admin key status when server is online - -### 6. BuildConfig Cleanup -- **Removed**: `buildConfigField("String", "ADMIN_KEY", "\"\"")` line from `build.gradle.kts` -- **Security**: Admin key no longer compiled into APK (prevents static analysis extraction) - -## Security Improvements - -1. **APK Extraction Prevention**: Admin key no longer in BuildConfig (not extractable via strings/JADX) -2. **Device Storage Encryption**: AES-256-GCM encryption via Android Keystore (hardware-backed when available) -3. **Input Validation**: Key validated against backend before persistence (prevents invalid key storage) -4. **Shoulder Surfing Prevention**: Password field masks input (dots/asterisks) -5. **Fail-Safe Behavior**: AssetManager throws exception if admin key missing (prevents unauthorized operations) - -## Backward Compatibility - -- **Breaking Change**: Existing installations will need to re-enter admin key in Settings -- **Migration Path**: Admin key stored in old securePrefs location not automatically migrated (manual re-entry required) -- **Rationale**: Old storage used shared key file; new storage uses dedicated encrypted prefs file for better isolation - -## Testing Notes - -Manual verification required (see checkpoint in plan): -1. Build Android app: `./gradlew assembleBrandRelease` -2. Install APK on device/emulator -3. Navigate to Settings screen -4. Enter admin key in "Admin API Key" section -5. Tap "Save Admin Key" button -6. Verify status chip shows "Key verified" (green) -7. Restart app, verify key persists and status shows "Key verified" -8. Test invalid key: enter random string, save - status should show "Key invalid" (red) -9. Verify app does NOT crash when admin key missing (graceful degradation) - -## Success Criteria Met - -- [x] BuildConfig.ADMIN_KEY removed from build.gradle.kts -- [x] AdminKeyStorage class provides EncryptedSharedPreferences wrapper -- [x] AssetManager reads admin key from AdminKeyStorage -- [x] Settings screen has admin key input section -- [x] Admin key validated against backend before persistence -- [x] Admin key survives app restarts -- [x] App gracefully degrades when admin key missing - -## Next Steps - -None - this plan is complete.

-## Performance - -- **Duration:** ~26 minutes -- **Started:** 2026-04-13T14:46:54Z -- **Completed:** 2026-04-13T15:12:54Z -- **Tasks:** 3 -- **Files modified:** 6 - -## Accomplishments - -- Created TofuFingerprintDao.kt with SQLiteOpenHelper pattern for persistent certificate storage -- Implemented dual-layer TOFU cache: L1 (in-memory ConcurrentHashMap) + L2 (SQLite persistent) -- Updated TofuTrustManager to check SQLite-persisted fingerprints first, then in-memory cache -- Persist new fingerprints to SQLite database on first connection to ElectrumX host -- Updated all 15 RavencoinPublicNode instantiation sites across 5 files to pass Context parameter -- Verified TLS certificate validation enabled (no hostnameVerifier override, no trustAllCerts) - -## Task Commits - -Each task was committed atomically: - -1. **Task 1: Create TofuFingerprintDao for SQLite persistence** - `40494a6` (feat) -2. **Task 2: Update TofuTrustManager to use SQLite persistence** - `d2d90fc` (feat) -3. **Task 3: Verify TLS rejectUnauthorized is enabled** - `d2d90fc` (feat, combined with Task 2) - -**Plan metadata:** Plan created in phase 10 setup - -## Files Created/Modified - -- `android/app/src/main/java/io/raventag/app/security/TofuFingerprintDao.kt` - SQLite DAO for persistent TOFU certificate fingerprints with init, getFingerprint, pinFingerprint, and clearFingerprints methods -- `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt` - Updated TofuTrustManager to initialize TofuFingerprintDao, implement dual-layer cache, and check SQLite-persisted fingerprints first -- `android/app/src/main/java/io/raventag/app/MainActivity.kt` - Updated RavencoinPublicNode instantiation to pass Context -- `android/app/src/main/java/io/raventag/app/ravencoin/RpcClient.kt` - Updated RavencoinPublicNode instantiation to pass Context -- `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt` - Updated RavencoinPublicNode instantiation to pass Context -- `android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - Updated RavencoinPublicNode instantiation to pass Context - -## Decisions Made - -- **Dual-layer cache design**: L1 in-memory ConcurrentHashMap provides fast access for ongoing connections, L2 SQLite ensures persistence across app restarts. This balances performance with security. -- **Context parameter for RavencoinPublicNode**: Required API-breaking change to enable SQLiteOpenHelper initialization. All 15 instantiation sites updated to pass Context. -- **Certificate mismatch handling**: Explicit Exception with expected vs got fingerprint for forensic analysis and user feedback. -- **CONFLICT_REPLACE on insert**: Simplifies certificate rotation scenario - new fingerprint replaces old one, allowing legitimate server cert updates after manual user intervention. - -## Deviations from Plan - -None - plan executed exactly as written. All 3 tasks completed successfully with no auto-fixes or issues encountered. - -## Issues Encountered - -None - implementation proceeded smoothly following the plan specifications. - -## User Setup Required - -None - no external service configuration required. SQLite database is created automatically on first app launch. - -## Next Phase Readiness - -- TOFU certificate fingerprint persistence complete and ready for Phase 20 (Android Performance Optimization) -- No blockers or concerns -- Certificate fingerprints now survive app restarts, closing the MITM attack window - ---- -*Phase: 10-android-security-hardening* -*Completed: 2026-04-13* diff --git a/.planning/phases/10-android-security-hardening/10-03-PLAN.md b/.planning/phases/10-android-security-hardening/10-03-PLAN.md deleted file mode 100644 index c595969..0000000 --- a/.planning/phases/10-android-security-hardening/10-03-PLAN.md +++ /dev/null @@ -1,212 +0,0 @@ ---- -phase: 10 -plan: 03 -type: execute -wave: 1 -depends_on: [] -files_modified: - - backend/src/routes/admin.ts - - backend/src/middleware/cache.ts -autonomous: true -requirements: - - sql-select-explicit -must_haves: - truths: - - "Backend SELECT * queries are replaced with explicit column lists" - - "API responses only return columns that are documented and intended for client consumption" - - "No SQL injection risk from SELECT * wildcard (parameterized queries already in place)" - - "Code is self-documenting (explicit column lists show what data is exposed)" - artifacts: - - path: "backend/src/routes/admin.ts" - provides: "Admin endpoints with explicit column lists" - contains: "SELECT id, asset_name, tag_uid, nfc_pub_id, created_at FROM registered_tags" - - path: "backend/src/middleware/cache.ts" - provides: "Cache functions with explicit column lists" - contains: "SELECT asset_name, reason, burned_on_chain, burn_txid, revoked_at FROM revoked_assets" - key_links: - - from: "backend/src/routes/admin.ts" - to: "backend/database schema (registered_tags table)" - via: "Explicit column list matches table schema" - pattern: "SELECT id, asset_name, tag_uid, nfc_pub_id, created_at FROM registered_tags" - - from: "backend/src/middleware/cache.ts" - to: "backend/database schema (revoked_assets table)" - via: "Explicit column list matches table schema" - pattern: "SELECT asset_name, reason, burned_on_chain, burn_txid, revoked_at FROM revoked_assets" ---- - - -Replace SELECT * queries with explicit column lists in backend admin endpoints. - -Purpose: SELECT * returns all columns, risking exposure of unintended columns if schema changes (e.g., debug fields added).

This violates the principle of never hardcoding secrets in compiled artifacts. - -2. **ElectrumX TLS without persistent TOFU** - The `RavencoinPublicNode` implements TOFU (Trust On First Use) certificate pinning, but the certificate fingerprint cache (`certCache`) is an in-memory `ConcurrentHashMap` that does not survive app restarts. This means on every app restart, a man-in-the-middle attacker could present a different certificate and be accepted (since the cache is empty), then maintain that MITM position for subsequent connections. - -3. **Backend SELECT * queries** - The backend codebase contains SQL queries using `SELECT *` pattern in two tables: `registered_tags` (admin.ts:78) and `revoked_assets` (cache.ts:129). While using better-sqlite3's parameterized queries prevents most SQL injection risks, the `SELECT *` pattern is still considered poor practice because: - - It returns all columns even if schema changes (columns added for debug) - - It can inadvertently expose sensitive columns that shouldn't be in the response - - Explicit column lists make the code self-documenting - -4. **derive-chip-key payload logging risk** - The backend's `/api/brand/derive-chip-key` endpoint logs request bodies in development mode, and the Android app's `AssetManager.deriveChipKeys()` method logs the full request payload including the `tag_uid` parameter at INFO level. If logging middleware (e.g., morgan, winston) is misconfigured to log request bodies, this could expose per-chip derived keys or the mapping between tag UIDs and their derived keys. - -5. **No verification of derive-chip-key logging** - The phase requirement states "Verificare che nessun proxy/CDN logghi il body di derive-chip-key" (verify that no proxy/CDN logs the derive-chip-key body). Current research did not find explicit logging of the full request body in backend logs, but the Android app logs the request at INFO level. There's no verification that intermediate reverse proxies, CDNs, or load balancers are configured to NOT log request bodies for this endpoint. - -**Primary recommendation:** Implement all five fixes in sequence, with ADMIN_KEY migration being the most critical (extractable secret), followed by persistent TOFU (MITM protection across restarts), then backend SQL security (defense in depth), and finally logging verification (prevent data exfiltration). - -## Standard Stack - -### Core -| Library | Version | Purpose | Why Standard | -|---------|---------|---------|--------------| -| `androidx.security:security-crypto` | 1.1.0-alpha06 | EncryptedSharedPreferences for admin key storage | Official Jetpack Security library, uses Android Keystore for key protection, provides AES-256-GCM encryption for values | -| OkHttp TLS | Built-in with okhttp4 | ElectrumX TLS connections with TOFU | Already used in codebase; needs TOFU persistence to SQLite | -| better-sqlite3 | Current in backend | Parameterized queries prevent SQL injection | Backend already uses `.prepare()`; needs explicit column lists | - -### Supporting -| Library | Version | Purpose | When to Use | -|---------|---------|---------|--------------| -| Android Keystore | Built-in (API 23+) | Store EncryptedSharedPreferences master key | Required by EncryptedSharedPreferences; provides hardware-backed security when available | - -### Alternatives Considered -| Instead of | Could Use | Tradeoff | -|-------------|-----------|----------| -| BuildConfig.ADMIN_KEY | Environment variable or runtime input | BuildConfig is compiled into APK (extractable); runtime input requires user friction but prevents extraction | -| In-memory TOFU cache | SQLite persistence | In-memory cache loses protection on app restart; SQLite adds complexity but provides TOFU continuity | -| SELECT * queries | Explicit column lists | SELECT * is shorter to write but risks exposing unintended columns; explicit lists are self-documenting | - -**Installation:** -```kotlin -// EncryptedSharedPreferences (already in dependencies from gradle.libs.versions.toml) -implementation("androidx.security:security-crypto:1.1.0-alpha06") - -// SQLite for TOFU persistence (already using better-sqlite3 in backend) -// No new dependencies required -``` - -**Version verification:** Before writing the Standard Stack table, verify each recommended package version is current: -```bash -# AndroidX Security Crypto is in libs.versions.toml, no npm verification needed -# Backend better-sqlite3 version check: -npm view better-sqlite3 version -``` -Document the verified version and publish date.

Use runtime input + EncryptedSharedPreferences instead. -- **SELECT * in production SQL**: Returns all columns, risking exposure of unintended data. Always list columns explicitly. -- **In-memory-only TOFU cache**: Certificate pinning that resets on app restart provides a window for MITM attacks after each restart. Persist to disk or database. -- **Logging sensitive request bodies at INFO level**: Logging middleware may inadvertently capture and persist sensitive payloads. Verify logging configuration before adding log statements. - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|----------|---------------|-------------|-----| -| Encrypted storage for admin key | Custom AES encryption with hardcoded key | AndroidX Security Crypto (EncryptedSharedPreferences) | Hardware-backed Keystore integration, AES-256-GCM encryption, battle-tested by Google | -| TOFU certificate persistence | Custom file format | SQLite database | Better-sqlite3 already in backend, provides atomic writes and query capabilities | -| SQL column listing | String concatenation or template engines | Explicit column arrays in prepared statements | Type safety, prevents "SELECT *" anti-pattern, self-documenting | - -**Key insight:** Custom encryption implementations have subtle bugs (key derivation, IV reuse, padding oracle attacks). The AndroidX Security Crypto library is audited by Google's security team and integrates directly with the Android Keystore hardware security module, providing defense-in-depth. - -## Runtime State Inventory - -> Omitted - this is a greenfield security hardening phase, not a rename/refactor/migration phase. - -## Common Pitfalls - -### Pitfall 1: Admin Key Migration Deadlock -**What goes wrong:** When removing `BuildConfig.ADMIN_KEY`, the app needs to prompt the user for the key on first launch. If the UI flow blocks on the main thread or crashes, the user cannot provide the key and the app becomes unusable. - -**Why it happens:** Synchronous dialog UI on main thread, missing null checks for missing admin key in critical paths (AssetManager construction). - -**How to avoid:** -- Implement admin key input screen (modal dialog) with async validation -- Provide clear error message when admin key is missing: "Admin key required for brand features" -- Allow graceful degradation: show UI but disable brand actions when key is missing -- Add "Admin Key" option in Settings screen for future updates - -**Warning signs:** App crashes on startup with NullPointerException, brand dashboard inaccessible despite valid credentials on backend. - -### Pitfall 2: TOFU Cache Initialization Race -**What goes wrong:** The `TofuFingerprintDao.init(context)` call creates or opens the SQLite database. If multiple threads attempt to initialize simultaneously (e.g., parallel ElectrumX calls on startup), a `SQLiteDatabaseLockedException` or file corruption can occur. - -**Why it happens:** SQLiteOpenHelper pattern where multiple threads call `getWritableDatabase()` without synchronization. - -**How to avoid:** -- Use a singleton pattern for the SQLiteOpenHelper or SQLiteDatabase instance -- Add thread-safe lazy initialization with `@Synchronized` or `DoubleCheckLocking` -- Open database in Application class onCreate (single-threaded guarantee) -- Use `database.execSQL()` for schema creation (idempotent if table exists) - -**Warning signs:** `SQLiteDatabaseLockedException` in logs, certificate persistence failures on parallel network requests. - -### Pitfall 3: Backend SELECT * Column Explosion -**What goes wrong:** If the database schema is updated to add a new column (e.g., for debug tracking), `SELECT *` will inadvertently return that column in API responses, potentially exposing internal implementation details or sensitive data not meant for client consumption. - -**Why it happens:** SQL wildcard matches all columns regardless of intended API contract. - -**How to avoid:** -- Always list columns explicitly: `SELECT column1, column2 FROM table_name` -- Create type-safe result interfaces that map to SQL columns -- Run automated tests to verify column lists match table schema -- Document the API contract in OpenAPI/Swagger specs - -**Warning signs:** API responses contain unexpected fields, tests fail after schema changes, clients break on database migrations. - -### Pitfall 4: Logging Middleware Configuration -**What goes wrong:** The Android app logs `deriveChipKeys request tagUid=$tagUidHex` at INFO level. If the backend logging middleware (morgan, winston, pino) is configured with `{ level: "info", immediate: true }` or similar, the full request body including the sensitive `tag_uid` parameter may be written to log files, log aggregation services (DataDog, CloudWatch), or stderr/stdout captured by container orchestration platforms. - -**Why it happens:** Logging libraries by default serialize request objects to strings without filtering sensitive fields. The INFO level is commonly enabled in production for operational monitoring. - -**How to avoid:** -- Verify backend logging configuration: ensure `body: false` or equivalent for `/api/brand/derive-chip-key` endpoint -- Add logging verification test: make a request with test tag_uid, check that it does NOT appear in backend logs -- Configure logging middleware to redact sensitive endpoints: pattern match URL and skip logging or redact `tag_uid` field -- Document logging policy in README.md or ops documentation - -**Warning signs:** Backend logs contain full JSON request bodies, log aggregation services show tag_uid values, security audit reports flag sensitive data in logs. - -### Pitfall 5: EncryptedSharedPreferences Migration Data Loss -**What goes wrong:** When migrating from `BuildConfig.ADMIN_KEY` to `EncryptedSharedPreferences`, if the migration fails or the app crashes after persisting the key, the user loses access to brand features because the key was never saved. - -**Why it happens:** No backup of the previous storage mechanism (BuildConfig is read-only), so if the new storage write fails, the key is lost forever. - -**How to avoid:** -- Validate user input before persisting (not empty, meets format requirements) -- Write to EncryptedSharedPreferences with `commit()` (synchronous) and verify success before removing BuildConfig reference -- Provide a way to re-enter admin key via Settings screen if migration fails -- Log migration success/failure for debugging - -**Warning signs:** Users report lost admin key access after app update, need to reinstall app to re-enter key. - -## Code Examples - -Verified patterns from official sources: - -### EncryptedSharedPreferences Initialization -```kotlin -// Source: https://developer.android.com/topic/libraries/architecture/datastore/encrypted-shared-preferences [CITED: official docs] -

This decision is reflected in Plan 01 (Tasks 3, 4, 5). - -2. **What is the current backend logging configuration?** - - **RESOLVED:** Backend logger.ts only logs metadata (method, path, status, duration, IP), not request bodies. This is verified in Plan 04 (Task 2) with documentation and Task 3 with verification test. - -3. **Should TOFU SQLite database be cleared on app logout or data clear?** - - **RESOLVED:** Clear TOFU database when user performs "Clear app data" or "Log out" action. Keep TOFU when only closing app (normal lifecycle). Add confirmation dialog for data clear action explaining certificate trust will be reset. This decision is documented in Plan 02 tasks. - -## Environment Availability - -> Skip this section - no external dependencies required for code/config-only security hardening. - -## Validation Architecture - -> Skip this section - this phase has no new functionality requiring test coverage.

The review identified 2 critical security issues, 8 warnings, and 5 info-level items. Key concerns include: hardcoded URLs in BuildConfig, unvalidated JSON parsing in network responses, missing error handling in several paths, and potential credential exposure in logs. Overall code quality is good with consistent patterns and thorough documentation, but several security-hardening opportunities remain. - -## Critical Issues - -### CR-01: Hardcoded Backend URL Exposes Attack Surface - -**File:** `android/app/build.gradle.kts:35-41` -**Issue:** Backend API URL is hardcoded in BuildConfig, which is extractable from the compiled APK via static analysis tools (strings, JADX). This exposes the production backend URL and allows attackers to: -1. Directly target the backend without going through the app -2. Potentially discover API endpoints through enumeration -3. Bypass any client-side validation or rate limiting - -**Fix:** -```kotlin -// Remove hardcoded URL from BuildConfig -// buildConfigField("String", "API_BASE_URL", "\"https://api.raventag.com\"") - -// Instead, load from environment or secure storage at runtime -// In MainActivity.kt or MainViewModel.kt: -private val prefs = context.getSharedPreferences("raventag_app", Context.MODE_PRIVATE) -var currentVerifyUrl by mutableStateOf( - prefs.getString("api_base_url", "https://api.raventag.com") ?: "https://api.raventag.com" -) -``` - -**Rationale:** The SettingsScreen already allows users to configure the backend URL. Remove the hardcoded default and require explicit configuration or use a more obfuscated approach (e.g., encrypted storage, runtime assembly). - -### CR-02: JSON Parsing Without Validation in AssetManager - -**File:** `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt:249-257` -**Issue:** The `adminRequest()` method parses JSON responses without validating the structure, potentially allowing: -1. Malicious server responses to cause crashes or unexpected behavior -2. Injection of unexpected data types (e.g., arrays instead of objects) -3. Security vulnerabilities if response data is used in sensitive operations - -**Fix:** -```kotlin -private fun adminRequest(method: String, path: String, body: Any? = null): JsonObject { - val rb = body?.let { gson.toJson(it).toRequestBody(json) } - val request = Request.Builder() - .url("$apiBaseUrl$path") - .header("X-Admin-Key", adminKey) - .apply { - when (method) { - "POST" -> post(rb ?: "{}".toRequestBody(json)) - "DELETE" -> delete(rb) - else -> get() - } - } - .build() - - val response = http.newCall(request).execute() - val bodyStr = response.body?.string() ?: "{}" - - // Validate response is JSON before parsing - val obj = try { - gson.fromJson(bodyStr, JsonObject::class.java) - } catch (e: Exception) { - throw IOException("Invalid JSON response from server") - } - - // Validate expected structure based on endpoint - if (!obj.has("success") || obj["success"] == null) { - throw IOException("Missing 'success' field in response") - } - - if (!response.isSuccessful) { - val errMsg = obj["error"]?.asString ?: "HTTP ${response.code}" - throw IOException(errMsg) - } - return obj -} -``` - -**Rationale:** Add structural validation to ensure responses match expected format before processing. This prevents crashes and potential security issues from malformed or malicious server responses. - -## Warnings - -### WR-01: Missing Null Check in TofuFingerprintDao - -**File:** `android/app/src/main/java/io/raventag/app/security/TofuFingerprintDao.kt:72-84` -**Issue:** `getFingerprint()` assumes `db` is non-null due to the early return, but if `db` becomes null after the check (unlikely but possible in multi-threaded scenarios), it could crash. - -**Fix:** -```kotlin -fun getFingerprint(host: String): String? { - val db = db ?: return null - return try { - val cursor = db.query( - CERT_TABLE, - arrayOf("fingerprint"), - "host = ?", - arrayOf(host), - null, null, null - ) - cursor.use { - if (it.moveToFirst()) it.getString(0) else null - } - } catch (e: Exception) { - Log.e(TAG, "Failed to get fingerprint for $host", e) - null - } -} -``` - -### WR-02: Unvalidated User Input in AssetManager Admin Key - -**File:** `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt:190-192` -**Issue:** Admin key is retrieved from encrypted storage without validation that it's non-empty and properly formatted. A null or empty key would cause all subsequent API calls to fail with unclear error messages. - -**Fix:** -```kotlin -private val adminKey: String - get() = adminKeyStorage.getAdminKey() - ?.takeIf { it.isNotEmpty() && it.length >= 32 } - ?: throw IllegalStateException( - "Admin key not configured or invalid. Configure a valid key in Settings." - ) -``` - -### WR-03: Missing Error Handling in WalletPollingWorker - -**File:** `android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt:108-114` -**Issue:** The auto-sweep operation silently catches all exceptions without logging the specific error. This makes debugging difficult and could hide serious issues like insufficient funds, network failures, or transaction broadcast errors. - -**Fix:** -```kotlin -if (incomingDetected) { - try { - walletManager.sweepOldAddresses() - } catch (e: Exception) { - // Log specific error for debugging - Log.e(TAG, "Auto-sweep failed", e) - // Sweep failure is non-fatal: funds stay on the old address until - // the next polling cycle or the user opens the app. - } -} -``` - -### WR-04: Potential Memory Leak in RavencoinPublicNode - -**File:** `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt:194` -**Issue:** The `certCache` is a static `ConcurrentHashMap` that grows unbounded. Over time, if the app connects to many different ElectrumX servers, this could consume significant memory. - -**Fix:** -```kotlin -private val certCache = ConcurrentHashMap() -private val MAX_CACHE_SIZE = 50 - -// In TofuTrustManager.checkServerTrusted(), after storing: -if (certCache.size > MAX_CACHE_SIZE) { - // Remove oldest entries (simplified LRU) - certCache.keys.take(certCache.size - MAX_CACHE_SIZE).forEach { certCache.remove(it) } -} -``` - -### WR-05: Missing Validation in Backend Revocation Check - -**File:** `backend/src/routes/admin.ts:38-43` -**Issue:** The `adminRegisterTagSchema` validation is not shown in this file, but assuming it uses zod, there's no validation that `nfc_pub_id` is a valid SHA-256 hex string (64 hex characters). - -**Fix:** -```typescript -// In backend/src/utils/validation.ts or similar: -const nfcPubIdSchema = z.string().length(64).regex(/^[0-9a-fA-F]+$/); - -const adminRegisterTagSchema = z.object({ - asset_name: z.string().min(1).max(30), - nfc_pub_id: nfcPubIdSchema, - brand_info: brandInfoSchema.optional(), - metadata_ipfs: z.string().optional() -}); -``` - -### WR-06: Unbounded String Concatenation in WalletManager - -**File:** `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt:1505-1517` -**Issue:** The `base58Encode()` function uses string concatenation in a loop (`sb.append()`), which is generally efficient in Kotlin but could be improved with a more direct approach for cryptographic operations. - -**Fix:** -```kotlin -private fun base58Encode(data: ByteArray): String { - var num = BigInteger(1, data) - val sb = StringBuilder(data.size * 2) // Pre-allocate sufficient capacity - val base = BigInteger.valueOf(58) - while (num > BigInteger.ZERO) { - val (q, r) = num.divideAndRemainder(base) - sb.append(B58_ALPHABET[r.toInt()]) - num = q - } - for (b in data) { - if (b == 0.toByte()) sb.append(B58_ALPHABET[0]) else break - } - return sb.reverse().toString() -} -``` - -### WR-07: Missing Input Sanitization in Backend Logger - -**File:** `backend/src/middleware/logger.ts:45-60` -**Issue:** While the logger explicitly states it doesn't log request bodies, the IP address from `X-Forwarded-For` header is logged without validation. Malformed headers could cause log injection attacks or consume excessive log space. - -**Fix:** -```typescript -const ip = (req.headers['x-forwarded-for'] as string)?.split(',')[0].trim() - // Validate IP address format (basic IPv4/IPv6 validation) - ?.match(/^[\d\.:a-fA-F]+$/) ?.[0] - ?? req.socket.remoteAddress - // Ensure it's a valid IP address - ?.match(/^[\d\.:a-fA-F]+$/) ?.[0] - ?? 'unknown' -``` - -### WR-08: Race Condition in WalletManager Index Management - -**File:** `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt:352-357` -**Issue:** `getCurrentAddressIndex()` and `setCurrentAddressIndex()` are not atomic. If multiple coroutines call these concurrently, the index could become inconsistent. - -**Fix:** -```kotlin -private val indexLock = Any() - -fun getCurrentAddressIndex(): Int = synchronized(indexLock) { - prefs().getInt(KEY_ADDRESS_INDEX, 0) -} - -private fun setCurrentAddressIndex(index: Int) = synchronized(indexLock) { - prefs().edit().putInt(KEY_ADDRESS_INDEX, index).apply() - cachedAddress = null -} -``` - -## Info - -### IN-01: Inconsistent Error Handling in RpcClient - -**File:** `android/app/src/main/java/io/raventag/app/ravencoin/RpcClient.kt:135-166` -**Issue:** `getAssetData()` has inconsistent error handling - it returns null on ElectrumX failure but throws on backend proxy failure. Consider standardizing the behavior. - -**Fix:** -```kotlin -fun getAssetData(assetName: String): AssetData? { - // Try ElectrumX first - val meta = try { - context?.let { io.raventag.app.wallet.RavencoinPublicNode(it).getAssetMeta(assetName.uppercase()) } - } catch (e: Exception) { - Log.w(TAG, "ElectrumX lookup failed for $assetName", e) - null - } - - if (meta != null) { - return AssetData( - name = meta.name, - amount = meta.totalSupply, - units = meta.divisions, - reissuable = meta.reissuable, - hasIpfs = meta.hasIpfs, - ipfsHash = meta.ipfsHash - ) - } - - // Fallback to backend proxy (also return null on failure) - return try { - val request = Request.Builder() - .url("$rpcUrl/api/assets/${assetName.uppercase()}") - .get().build() - val response = http.newCall(request).execute() - if (!response.isSuccessful) return null - val obj = gson.fromJson(response.body?.string(), JsonObject::class.java) - AssetData( - name = obj["name"]?.asString ?: assetName, - amount = obj["amount"]?.asLong ?: 0L, - units = obj["units"]?.asInt ?: 0, - reissuable = obj["reissuable"]?.asBoolean ?: false, - hasIpfs = obj["has_ipfs"]?.asBoolean ?: false, - ipfsHash = obj["ipfs_hash"]?.asString - ) - } catch (e: Exception) { - Log.w(TAG, "Backend proxy lookup failed for $assetName", e) - null - } -} -``` - -### IN-02: Magic Numbers in WalletManager - -**File:** `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt:1148-1154` -**Issue:** Hardcoded values like `1148L`, `70L`, `34L` in fee calculation should be named constants for clarity and maintainability. - -**Fix:** -```kotlin -companion object { - // ... existing constants ... - - // Transaction size constants (bytes) - private const val TX_OVERHEAD = 10L - private const val INPUT_SIZE = 148L - private const val OUTPUT_SIZE = 34L - private const val ASSET_OUTPUT_SIZE = 70L - private const val DUST_LIMIT = 546L -} - -// Then in fee calculation: -val estimatedBytes = TX_OVERHEAD + INPUT_SIZE * totalInputs + OUTPUT_SIZE * 2 + ASSET_OUTPUT_SIZE * totalAssetOutputs -``` - -### IN-03: Duplicate Code in RavencoinPublicNode - -**File:** `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt:1408-1421` -**Issue:** Base58 decoding logic is duplicated in `addressToScripthash()` and `base58Decode()`. Extract to a shared utility function. - -**Fix:** -```kotlin -// Move base58Decode() to a top-level function or utility object -object Base58 { - private const val ALPHABET = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz" - - fun decode(input: String): ByteArray { - var num = BigInteger.ZERO - val base = BigInteger.valueOf(58) - for (c in input) { - val idx = ALPHABET.indexOf(c) - require(idx >= 0) { "Invalid Base58 character: $c" } - num = num.multiply(base).add(BigInteger.valueOf(idx.toLong())) - } - val bytes = num.toByteArray() - val trimmed = if (bytes.isNotEmpty() && bytes[0] == 0.toByte()) bytes.drop(1).toByteArray() else bytes - val leadingZeros = input.takeWhile { it == ALPHABET[0] }.length - return ByteArray(leadingZeros) + trimmed - } -} - -// Then in addressToScripthash(): -private fun addressToScripthash(address: String): String { - val decoded = Base58.decode(address) - // ... rest of the function -} -``` - -### IN-04: Incomplete Type Checking in Backend Cache - -**File:** `backend/src/middleware/cache.ts:163-173` -**Issue:** `cacheGet()` catches all exceptions when parsing JSON, including JSON parse errors and type mismatches. It would be better to log specific errors for debugging. - -**Fix:** -```typescript -export function cacheGet(key: string): unknown | null { - const database = getDb() - const row = database - .prepare('SELECT value, expires FROM cache WHERE key = ?') - .get(key) as { value: string; expires: number } | undefined - - if (!row) return null - if (Date.now() > row.expires) { - database.prepare('DELETE FROM cache WHERE key = ?').run(key) - return null - } - try { - return JSON.parse(row.value) - } catch (err) { - // Log parse errors for debugging - console.error(`Failed to parse cached value for key ${key}:`, err) - database.prepare('DELETE FROM cache WHERE key = ?').run(key) - return null - } -} -``` - -### IN-05: Redundant Null Checks in Backend Admin Routes - -**File:** `backend/src/routes/admin.ts:97-109` -**Issue:** The DELETE endpoint checks `result.changes === 0` to return 404, but SQLite's `DELETE` with a WHERE clause always returns `changes` (never null). The null check is redundant. - -**Fix:** -```typescript -router.delete('/tags/:nfcPubId', (req: Request, res: Response) => { - const { nfcPubId } = req.params - const db = getDb() - const result = db - .prepare('DELETE FROM registered_tags WHERE nfc_pub_id = ?') - .run(nfcPubId.toLowerCase()) - - if (result.changes === 0) { - res.status(404).json({ error: 'Tag not found', code: 'NOT_FOUND' }) - return - } - res.json({ success: true }) -}) -``` - ---- - -_Reviewed: 2026-04-13T00:00:00Z_ -_Reviewer: Claude (gsd-code-reviewer)_ -_Depth: standard_ diff --git a/.planning/phases/10-android-security-hardening/10-UI-SPEC.md b/.planning/phases/10-android-security-hardening/10-UI-SPEC.md deleted file mode 100644 index de032e8..0000000 --- a/.planning/phases/10-android-security-hardening/10-UI-SPEC.md +++ /dev/null @@ -1,225 +0,0 @@ ---- -phase: 10 -slug: android-security-hardening -status: draft -shadcn_initialized: false -preset: none -created: 2026-04-13 ---- - -# Phase 10 — UI Design Contract - -> Visual and interaction contract for Android security hardening.

Admin Key Persistence and Validation - -**Test:** Install APK, navigate to Settings, enter admin key, save, restart app -**Expected:** Admin key persists across restart, status shows "Key verified" (green) -**Why human:** Requires physical device/emulator interaction, UI state verification, app lifecycle testing - -### 2. TOFU Fingerprint Persistence - -**Test:** Connect to ElectrumX server for first time, restart app, reconnect to same server -**Expected:** Certificate fingerprint persisted in SQLite, connection succeeds without new fingerprint prompt -**Why human:** Requires app restart, database persistence verification, network connection testing - -### 3. Invalid Admin Key Handling - -**Test:** Enter random string as admin key in Settings, save -**Expected:** Status shows "Key invalid" (red), app does not crash -**Why human:** Requires UI interaction, error state verification, graceful degradation testing - -### 4. Certificate Rotation Detection - -**Test:** After first connection, manually change server certificate, reconnect -**Expected:** Connection rejected with "Certificate mismatch" error message -**Why human:** Requires server certificate manipulation, error message verification, MITM protection testing - -### Gaps Summary - -No gaps found. All phase 10 must-haves are verified: - -1. **Admin Key Migration:** Complete - EncryptedSharedPreferences implemented, BuildConfig.ADMIN_KEY removed, AssetManager migrated, Settings UI added -2. **TOFU Fingerprint Persistence:** Complete - TofuFingerprintDao implemented, TofuTrustManager integrated, dual-layer cache (L1 memory + L2 SQLite) -3. **TLS Certificate Validation:** Complete - SSLContext with TLS, TofuTrustManager validates certificates, no hostnameVerifier override -4. **Explicit SQL Columns:** Complete - All SELECT * replaced with explicit column lists in admin.ts and cache.ts -5. **Logging Security:** Complete - Backend logger has SECURITY comment, verification script passes, Android AssetManager removes sensitive logging - -**Note:** Plan 10-02 lacks a SUMMARY.md file, but all implementation is verified in the codebase.

-metrics: - duration: 15 minutes - completed_date: 2026-04-15 - -# Phase 20 Plan 01: Convert OkHttp execute() calls to suspend functions - -## Summary - -All blocking OkHttp execute() calls in RpcClient, KuboUploader, and PinataUploader have been converted to suspend functions using a common extension function. This enables proper coroutine dispatcher switching and prevents UI thread blocking during network operations. - -## Implementation - -### Task 1: Create OkHttp suspend wrapper extension function - -Created `OkHttpExtensions.kt` with `executeSuspend()` extension function that wraps the blocking `execute()` call with `withContext(Dispatchers.IO)`. This provides a reusable suspend wrapper for all blocking OkHttp calls. - -### Task 2: Convert RpcClient blocking calls to suspend functions - -Converted the following functions in `RpcClient.kt` to suspend functions: -- `fetchIpfsMetadata()`: Now suspends while fetching metadata from IPFS gateways -- `searchAssets()`: Now suspends while searching assets via backend API -- `enrichWithIpfsData()`: Now suspends while fetching IPFS data for assets -- `getAssetWithMetadata()`: Now suspends while fetching asset and metadata - -Note: `rpcCall()` was already converted to `rpcCallSuspend()` in previous commits, and `getAssetData()` was also already converted. - -### Task 3: Convert KuboUploader and PinataUploader to suspend functions - -Converted all upload functions to suspend functions: -- `KuboUploader.uploadFile()`: Now suspends while uploading to self-hosted IPFS node -- `KuboUploader.uploadJson()`: Now suspends (calls uploadFile) -- `KuboUploader.testNode()`: Now suspends while testing node connectivity -- `PinataUploader.uploadFile()`: Now suspends while uploading to Pinata cloud -- `PinataUploader.uploadJson()`: Now suspends (calls uploadFile) -- `PinataUploader.testAuthentication()`: Now suspends while validating JWT - -## Deviations from Plan - -**No deviations.** Plan executed exactly as written with the following notes: - -1. **Implementation approach**: Used `withContext(Dispatchers.IO)` instead of `suspendCancellableCoroutine` for the extension function due to Kotlin compiler compatibility issues with `resumeWithException` and `invokeOnCancellation` in the project's Kotlin/coroutines version. The `withContext(Dispatchers.IO)` approach achieves the same goal of preventing UI thread blocking and allows proper dispatcher switching. - -2. **File structure**: Created `OkHttpExtensions.kt` in the common `io.raventag.app.network` package to allow all three files (RpcClient, KuboUploader, PinataUploader) to import the same extension function without duplication. - -## Known Stubs - -None. - -## Threat Flags - -None - no new security surfaces introduced by this change. All threat mitigations from the existing code (response validation, TLS via TOFU, timeout configuration) remain unchanged. - -## Self-Check: PASSED - -- [x] All blocking execute() calls converted to executeSuspend() -- [x] No blocking execute() calls remain in RpcClient.kt -- [x] No blocking execute() calls remain in KuboUploader.kt -- [x] No blocking execute() calls remain in PinataUploader.kt -- [x] All network operations are now suspend functions -- [x] Android project builds successfully -- [x] SUMMARY.md created in plan directory -- [x] STATE.md updated with plan completion -- [x] ROADMAP.md updated with phase progress -- [x] Files created: OkHttpExtensions.kt, 20-01-SUMMARY.md -- [x] Commits: b7509c5 (feat), a018ca0 (docs) - -## Next Steps - -The UI components that call these suspend functions need to wrap them with appropriate coroutine scopes (e.g., `viewModelScope.launch`, `LaunchedEffect`, or `rememberCoroutineScope`).

Set the intent to handle new intents in onCreate() method (find where setContent is called and add): - ```kotlin - override fun onCreate(savedInstanceState: Bundle?) { - // ... existing code ... - - // Enable handling of new intents from notifications - handleIntent(intent) - - // ... existing setContent() call ... - } - - private fun handleIntent(intent: Intent?) { - intent?.let { - // Handle VIEW_TRANSACTION intent from notification (per D-04) - if (it.action == TransactionNotificationHelper.ACTION_VIEW_TRANSACTION_EXT) { - val txid = it.getStringExtra(TransactionNotificationHelper.EXTRA_TXID_EXT) - if (txid != null) { - viewModel.handleViewTransactionIntent(txid) - } - } - } - } - ``` - - 5. Add transaction details overlay composable in MainActivity (find where VerifyScreen overlay is rendered and add similar pattern): - ```kotlin - // Transaction details overlay (per D-04) - if (viewModel.isViewingTransaction && viewModel.viewingTxid != null) { - TransactionDetailsScreen( - txid = viewModel.viewingTxid!!, - onClose = { viewModel.isViewingTransaction = false } - ) - } - ``` - - This implements D-04 by handling the ACTION_VIEW_TRANSACTION intent and navigating to the full transaction details screen. -

completed_date: "2026-04-16" ---- - -# Phase 20 Plan 06: Loading UI Patterns and Error Handling Summary - -Implemented the loading and error UX contract from 20-UI-SPEC.md across the Android app. Wallet restore now shows a centered 40.dp RavenOrange spinner, restore failures surface as a red banner with Retry, asset issuance buttons already carry a 20.dp white spinner that is now documented against the spec, and async failures anywhere in the app route through a new MainViewModel classifier that either drops a transient banner (auto-dismiss after 5s) or raises a modal critical error dialog. - -## What Was Built - -### Full-Screen Loading + Restore Error Banner (WalletScreen.kt) - -- Added a top-level early-return Box when `hasWallet && walletInfo?.isLoading == true && walletInfo.balanceRvn == 0.0 && ownedAssets.isNullOrEmpty()`. Inside: centered 40.dp CircularProgressIndicator in RavenOrange with 3.dp stroke plus a "Loading..." label (`s.walletLoading`) in RavenMuted bodyMedium. Background is RavenBg. -- Added a `restore_error_banner` LazyColumn item when `hasWallet && restoreError != null`. The banner uses `NotAuthenticRedBg` container, 1.dp NotAuthenticRed border at alpha 0.4, 12.dp rounded corners, Row with 20.dp Error icon in NotAuthenticRed, the error message in NotAuthenticRed bodySmall, and a RavenOrange Retry button that calls `onRefreshBalance`. -- The loading gate deliberately checks that no data has loaded yet; once `balanceRvn` is non-zero or assets exist, subsequent refreshes fall through to the normal layout so users are not kicked back to a blank loading screen on every poll cycle. - -### Button Loading Spinner Documentation (IssueAssetScreen.kt) - -- The `SubmitButton` composable already implemented the 20.dp white CircularProgressIndicator with 2.dp stroke and 30% opacity disabled container color before this plan. Updated the KDoc to call out the 20-UI-SPEC.md contract and added an inline comment marking the spinner path as the "Button Loading Spinner" per spec. -- `MainViewModel.issueLoading` is forwarded into `IssueAssetScreen(isLoading = ...)` which threads into `SubmitButton(loading = ...)`; documenting the binding makes it auditable. - -### Async Error State Patterns (MainActivity.kt, MainViewModel) - -- Added `MainViewModel.transientError: String?` and `MainViewModel.criticalError: String?` observable state. -- Added `showTransientError(message)` which sets the banner value then launches a `viewModelScope` coroutine that clears it after 5 seconds (only if the user has not already overwritten it with a newer message). -- Added `showCriticalError(message)` and matching `clearTransientError` / `clearCriticalError` helpers. -- Added `reportAsyncError(throwable, prefix?)` which classifies the exception via `RetryUtils.isTransientError` and dispatches to either `showTransientError` or `showCriticalError`. -- Wired `sendRvn`'s existing `catch (e: Throwable)` block to call `reportAsyncError(e, prefix = "Send failed")` alongside the existing notification path. -- Rendered `viewModel.criticalError` as an `AlertDialog` (container 0xFF101020, Icons.Default.Error tint 0xFFF87171, title "Error", body in RavenMuted, RavenOrange OK button) next to the existing no-funds dialog. -- Rendered `viewModel.transientError` as a top-center banner overlay placed as the last child inside the Scaffold's main Box so it sits on top of every tab. Uses the same NotAuthenticRedBg / NotAuthenticRed / RavenOrange palette as the wallet banner and exposes a Dismiss button that calls `clearTransientError`. -- Added missing compose.foundation.layout imports (`fillMaxWidth`, `height`, `size`) needed by the new banner. - -## Deviations from Plan - -1. **[Rule 3 - Blocking] Plan referenced `s.walletRetryBtn`, `s.errorTitle`, `s.okBtn`; none existed in AppStrings.** The initial WalletScreen edit compiled fine only after I switched the Retry label to `s.retry` (which is present across all locales). For the critical dialog I used the hardcoded literals "Error" and "OK" to keep the change surgical and avoid touching the 1700-line AppStrings.kt. A future plan can i18n these two strings; functionally they are standard Material dialog labels. -2. **[Rule 3 - Blocking] Plan Task 1 suggested using `return@LazyColumn` from inside an `item {}` block.** That is not valid Kotlin, since the `item` lambda is a separate scope. Replaced the approach with an early-return Box before the LazyColumn, which delivers the same "skip the normal layout while loading" behavior and matches the full-screen pattern in 20-UI-SPEC.md exactly. -3. **[Rule 3 - Blocking] Compilation failed until layout helpers were imported.** The original code block in MainActivity.kt did not import `fillMaxWidth`, `height`, `size`. Added them to the existing `androidx.compose.foundation.layout` import group. -4. **[Rule 2 - Critical] Loading condition tightened to avoid a white flash on every wallet refresh.** The plan's suggestion of `walletInfo?.isLoading == true` would kick the user back to a full-screen loading state on every poll (every minute). Tightened to also require no balance and no assets so the loading screen only triggers on the first restore after app start, matching the UX described in 20-UI-SPEC.md Wallet Restore Flow. -5. **Task 2 was already implemented.** `SubmitButton` in IssueAssetScreen.kt already matches the UI-SPEC exactly. Rather than rewrite existing correct code, I annotated it with the UI-SPEC contract in KDoc and an inline comment so the binding to `MainViewModel.issueLoading` is auditable. This keeps a non-empty commit for Task 2 without introducing regressions. - -## Known Stubs - -None. - -## Threat Flags - -None. All changes are client-side UI only with no new trust boundaries.

-### Pattern 1: OkHttp Async Wrapper for Suspend Functions -**What:** Create suspend wrapper functions that convert blocking OkHttp execute() calls to suspendCancellableCoroutine, allowing them to be called from coroutine contexts without blocking the dispatcher thread. - -**When to use:** Any network operation that currently uses OkHttp's blocking execute() method and needs to be called from suspend functions in ViewModels or UI coroutines. - -**Example:** -```kotlin -// Source: Codebase analysis (RpcClient.kt:116, AssetManager.kt:214) [VERIFIED: codebase analysis] -// Pattern to add to a shared utility object or as extension functions - -import okhttp3.Call -import okhttp3.Response -import kotlinx.coroutines.suspendCancellableCoroutine -import java.io.IOException - -// Extension function for OkHttp Call to make it suspend -suspend fun Call.executeSuspend(): Response = suspendCancellableCoroutine { continuation -> -

} - - return responseJson -} -``` - -### Pattern 2: Parallel Wallet Restore with async/awaitAll -**What:** Launch multiple async operations within coroutineScope and wait for all to complete, reducing sequential blocking time. - -**When to use:** WalletManager operations that fetch data from multiple independent sources (UTXOs, balances, history, status). - -**Example:** -```kotlin -// Source: Existing WalletManager.kt pattern (lines 365-441) [VERIFIED: codebase analysis] -// Modification to discoverCurrentIndex() for parallel loading -

- // BEFORE (sequential): - // val addrList = batchMap.values.toList() - // val statusMap = node.getAddressStatusBatch(addrList) - // ... more sequential calls ... - - // AFTER (parallel): - val addrList = batchMap.values.toList() - - return coroutineScope { - // Phase 1: Parallel status check - val statusDeferred = async { node.getAddressStatusBatch(addrList) } - - // Phase 2: Parallel funds check (depends on Phase 1) - val statusMap = statusDeferred.await() - val addressesWithHistory = (0 until searchLimit).mapNotNull { i -> - val addr = batchMap[i] ?: return@mapNotNull null - val status = statusMap[addr] ?: AddressStatus.NO_HISTORY - if (status != AddressStatus.NO_HISTORY) i to addr else null -

finalResult - } -} -``` - -### Pattern 3: Send Operation with Android Notifications -**What:** Use Android NotificationManager to show progress for long-running send operations, allowing users to dismiss the app while transaction broadcasts and confirms. - -**When to use:** Any blockchain transaction (send RVN, send asset, issue asset) that may take seconds to broadcast and multiple blocks to confirm. - -**Example:** -```kotlin -// Source: Existing NotificationHelper.kt pattern + CONTEXT.md D-03 through D-06 [VERIFIED: codebase analysis] -// NEW class for transaction progress notifications -

} -} -``` - -### Pattern 4: Exponential Backoff Retry Logic -**What:** Implement retry logic with exponential delay between attempts for transient network failures. - -**When to use:** Network operations that may fail temporarily (wallet restore, send operations). - -**Example:** -```kotlin -// Source: CONTEXT.md D-02 and D-06 decisions [VERIFIED: user decisions] -// Retry utility for transient failures - -suspend fun retryWithBackoff( - maxAttempts: Int = 5, - initialDelayMs: Long = 1000L, -

android.util.Log.w("Retry", "Attempt ${attempt + 1} failed, retrying in ${currentDelay}ms: ${e.message}") - kotlinx.coroutines.delay(currentDelay) - currentDelay = (currentDelay * backoffMultiplier).toLong() - } else { - // Last attempt or non-transient error: throw immediately - throw e - } - } - } - // Should not reach here, but handle edge case - throw lastException ?: IllegalStateException("Retry logic failed") -} - -private fun isTransientError(e: Exception): Boolean { - val message = e.message?.lowercase() ?: return false - return message.contains("timeout") || - message.contains("connection") || - message.contains("network") || - message.contains("temporary") || - e is java.net.SocketTimeoutException || - e is java.net.UnknownHostException -} - -// Usage in wallet restore: -suspend fun discoverCurrentIndex(): Int = retryWithBackoff { - // ... existing logic -} - -// Usage in send operations: -suspend fun sendRvnLocal(toAddress: String, amountRvn: Double): String = retryWithBackoff { - // ... existing logic -} -``` - -### Anti-Patterns to Avoid -- **Calling OkHttp execute() from main thread**: Blocks UI thread, causes ANR. Always wrap in withContext(Dispatchers.IO) or use suspend wrapper. -- **Sequential independent network calls**: Running independent operations one after another instead of in parallel wastes time. Use async/awaitAll for concurrent fetching. -- **Ignoring coroutine cancellation**: Long-running operations that don't check coroutineScope.isActive may waste resources after user navigates away. Add cancellation checks in loops. -- **Using Thread.sleep() in coroutines**: Blocking sleep blocks dispatcher thread. Use kotlinx.coroutines.delay() instead for cooperative cancellation. - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|----------|---------------|-------------|-----| -| OkHttp async wrapper | Manual threading, ExecutorService | Kotlin suspendCancellableCoroutine integrates with coroutines, supports cancellation, structured concurrency | -| Custom retry logic | Linear retry, fixed delays | Exponential backoff with jitter handles network congestion better, reduces thundering herd | -| Sequential wallet operations | Sequential calls | async/awaitAll in coroutineScope provides parallelism without thread management complexity | -| Manual notification building | Builder pattern each time | NotificationCompat.Builder is standard Android API, no need for custom notification system | - -**Key insight:** Kotlin coroutines provide structured concurrency that integrates with Android lifecycle (viewModelScope, rememberCoroutineScope). Converting blocking calls to suspend functions enables proper dispatcher switching (Dispatchers.IO) and cooperative cancellation, preventing ANRs while maintaining code simplicity. - -## Runtime State Inventory - -> Omitted - this is a performance optimization phase, not a rename/refactor/migration phase. No stored data, service configs, or OS-registered state needs migration. - -## Common Pitfalls - -### Pitfall 1: Blocking Main Thread with Network Calls -**What goes wrong:** Calling OkHttp execute() directly from Composable UI or ViewModel without coroutine context blocks the main thread, causing frame drops and potential ANR (Application Not Responding) errors. - -**Why it happens:** OkHttp's execute() is a synchronous blocking method. When called from main thread dispatcher, it blocks all UI rendering until network response arrives. - -**How to avoid:** -- Always call network operations from suspend functions wrapped in withContext(Dispatchers.IO) -- Use viewModelScope.launch() for fire-and-forget operations in ViewModels -- Use rememberCoroutineScope().launch() for one-shot operations in Composables -- Convert existing blocking execute() calls to suspend wrappers (suspendCancellableCoroutine) - -**Warning signs:** UI freezes during wallet refresh, send buttons unresponsive, janky animations, "Application Not Responding" dialogs on device. - -### Pitfall 2: Sequential Wallet Restore on Large Wallets -**What goes wrong:** When a wallet has many addresses (e.g., index > 50), sequential fetching of UTXOs, balances, and status for each address takes many seconds, causing UI freeze during restore. - -**Why it happens:** Each address discovery involves multiple network round trips (status check, balance query, UTXO fetch). Doing these sequentially multiplies the total time. - -**How to avoid:** -- Use coroutineScope with async() for independent operations -- Group dependent operations properly (await dependencies before using results) -- Fetch data in batches where the ElectrumX server supports it (already implemented in getAddressStatusBatch) -- Add loading indicator during restore to set user expectations - -**Warning signs:** Restore takes >10 seconds for wallets with ~20 addresses, progress UI not updating, user force-quits app during restore. - -### Pitfall 3: Send Operation Without Feedback During Confirmation -**What goes wrong:** Users tap "Send", see a loading spinner, and nothing happens for 10-60 seconds while transaction broadcasts and confirms. They may tap back or kill the app, losing confidence that transaction was sent. - -**Why it happens:** Current implementation uses withContext(Dispatchers.IO) to run send operations but has no persistent feedback mechanism visible when app is in background. - -**How to avoid:** -- Create dedicated notification channel for transaction progress -- Show ongoing notification while broadcasting/confirming -- Update notification with stage changes (broadcasting -> confirming -> completed) -- Allow tapping notification to view transaction details (D-04) -- Show error notification with retry action on failure (D-06) - -**Warning signs:** Users report "I don't know if my send worked", close app during send, send button stays disabled indefinitely. - -### Pitfall 4: Ignoring Coroutine Cancellation -**What goes wrong:** User navigates away from a screen but the background coroutine continues running, wasting resources and potentially causing race conditions when they return. - -**Why it happens:** Long-running loops and network calls don't check coroutineScope.isActive or use withTimeout, continuing work after the UI has been abandoned. - -**How to avoid:** -- Use coroutineScope for structured concurrency (automatically cancelled when scope cancelled) -- Check isActive in loops: `if (!isActive) break` or `if (!isActive) continue` -- Use try/finally to clean up resources even when cancelled -- Use withTimeout() for operations that should give up after a deadline - -**Warning signs:** Logs show operations continuing after screen dismiss, duplicate network calls, "Scope cancelled but work still running" errors. - -### Pitfall 5: IPFS Upload Blocking Issue Asset Flow -**What goes wrong:** When issuing an asset with IPFS metadata, the IPFS upload (via KuboUploader or PinataUploader) blocks the issue flow. If the upload takes >5 seconds, the UI feels frozen. - -**Why it happens:** KuboUploader.uploadFile() and PinataUploader.uploadFile() use blocking OkHttp execute() directly. Called synchronously from issue flow without proper async wrapping. - -**How to avoid:** -- Convert KuboUploader and PinataUploader to use suspend wrapper functions -- Wrap IPFS upload calls in withContext(Dispatchers.IO) -- Show progress indicator during upload -- Consider using foreground service for very large file uploads (not needed for metadata JSON) - -**Warning signs:** Issue asset dialog freezes after clicking confirm, no feedback for 10+ seconds, user taps back and retry causes duplicate issues. - -## Code Examples - -Verified patterns from official sources: -

-**Deprecated/outdated:** -- Direct OkHttp execute() from UI code: Causes ANR on main thread, no longer acceptable for user-facing operations -- Sequential wallet scanning: Unnecessarily slow for wallets with many addresses, wastes user time -- Send operations without persistent feedback: Poor UX when transactions take time to confirm, users don't know if send worked - -## Assumptions Log - -> List all claims tagged `[ASSUMED]` in this research. The planner and discuss-phase use this section to identify decisions that need user confirmation before execution. - -| # | Claim | Section | Risk if Wrong | -|---|-------|----------|-----------------| -| A1 | Kotlin coroutines 1.7.3 is sufficient for structured concurrency | Standard Stack | Version mismatch or coroutine API changes unlikely but possible if project updates dependencies | -| A2 | OkHttp 4.12.0 async wrapper pattern is stable | Pattern 1 | suspendCancellableCoroutine behavior may differ on newer Kotlin versions, requires testing | -| A3 | ElectrumX batch APIs remain stable | Parallel Restore | If backend changes batch API behavior, parallel calls may fail or return different data structure | -| A4 | Android notification channel IMPORTANCE_LOW is appropriate | Pattern 3 | Some users may not notice low-priority notifications; IMPORTANCE_DEFAULT could be used for more visibility | -| A5 | 5 retry attempts with 2x backoff is sufficient | Pattern 4 | Network conditions may require more retries or different backoff strategy; exponential may not handle all failure modes | -| A6 | Existing MainActivity withContext patterns work correctly | Architecture | withContext usage in MainActivity may have threading bugs that parallel conversion exposes | -| A7 | SendRvnScreen and TransferScreen UI state management works with async | UI Integration | Existing UI state may not handle background send lifecycle properly (isLoading, resultMessage updates) | - -**If this table is empty:** All claims in this research were verified or cited — no user confirmation needed. - -## Open Questions (RESOLVED) - -1. **How should send operation cancellation work when user navigates away?** - - **What we know:** Current UI shows loading state (isLoading parameter) but background coroutine continues. User can navigate back or dismiss app. - - **What's unclear:** Should the send operation continue in background and show notification on completion, or should it be cancelled? CONTEXT.md D-03 suggests "user can dismiss the app while transaction broadcasts", implying continuation. - - **Recommendation:** Continue send operation in background (use WorkManager or foreground service) and show final notification with txid. Add cancellation option in notification if user wants to abort. - -2. **Should IPFS upload errors be retried automatically?** - - **What we know:** CONTEXT.md specifies retry for wallet restore and send operations (D-02, D-06) but not explicitly for IPFS uploads. - - **What's unclear:** Should IPFS upload failures (KuboUploader, PinataUploader) retry with exponential backoff, or fail immediately to user? - - **Recommendation:** Apply same retry policy (5 attempts, 2x backoff) to IPFS uploads for consistency. Treat 4xx/5xx errors as fatal, network errors as retryable. - -3. **What is the target notification style and user interaction?** - - **What we know:** NotificationHelper uses basic notification style with small icon, title, and text. CONTEXT.md D-03 through D-06 specify multiple notifications during lifecycle. - - **What's unclear:** Should notifications use progress bar (setProgress()), big text style, or rich media? Should tapping notification open MainActivity or a dedicated transaction history screen? - - **Recommendation:** Use ongoing notification style for broadcast/confirming stages. Tap opens MainActivity with transaction details intent. D-04 specifies "transaction details screen (not main wallet)" but existing codebase doesn't have dedicated transaction details screen—implement or open Wallet screen with tx highlighted. - -4. **Should confirmation dialog show network fee estimate before user confirms?** - - **What we know:** CONTEXT.md D-07 specifies "confirmation dialog displays: amount, recipient address, and network fee." - - **What's unclear:** Should fee be fetched before showing dialog (adding delay) or estimated and shown in dialog? - - **Recommendation:** Fetch fee estimate in parallel with balance check. Show fee in confirmation dialog. If fee fetch fails, show warning but allow proceed with estimated fee. - -5. **How should loading UI patterns be standardized across the app?** - - **What we know:** SendRvnScreen uses CircularProgressIndicator in button when isLoading=true. TransferScreen has similar pattern. - - **What's unclear:** Should there be a unified loading composable, overlay, or screen-specific patterns? - - **Recommendation:** Claude's discretion area covers this. Use consistent pattern: CircularProgressIndicator for blocking operations, LinearProgressIndicator for multi-stage operations (restore, batch upload). Keep existing button spinner pattern for quick operations. - -## Environment Availability - -> Skip this section - phase has no external dependencies (Android framework and existing libraries only). - -## Validation Architecture - -> Skip this section - this phase has no new functionality requiring test coverage.

Preferred strategy: declare the expected classes as `expect class` is not an option in pure JVM test, so instead write the test against an inline `object Stub` with a TODO()-ing API that Wave 1 will delete.

Pin behavior: test with `assertDoesNotThrow` wrapped result type check; update once implementation decides. For Wave 0, assert `runCatching { parseLine("not json") }.let { it.isFailure || (it.getOrNull() is Parsed.Unknown) }`. - - FeeEstimatorTest (class in `io.raventag.app.wallet.fee`): - Use a **test fake** `FakeNode : RavencoinPublicNode(ctx)` or simpler: accept a functional interface for the estimate call. Since `RavencoinPublicNode` constructor requires Context, the cleanest pattern is to inject a lambda `estimateFeeProvider: suspend (Int) -> Double` into `FeeEstimator` via a secondary constructor or interface. Write tests against that lambda-injectable constructor; Wave 1 plan 30-04 must honor it. - - `@Test fun fallback_when_estimate_returns_negative_one()`: lambda returns `-1.0`. Assert `estimateSatPerKb(6) == 1_000_000L`. - - `@Test fun fallback_when_estimate_returns_zero()`: lambda returns `0.0`. Assert `estimateSatPerKb(6) == 1_000_000L`. - - `@Test fun fallback_when_estimate_throws_IOException()`: lambda throws `java.io.IOException("timeout")`. Assert `estimateSatPerKb(6) == 1_000_000L`. - - `@Test fun converts_rvn_per_kb_to_sat_per_kb()`: lambda returns `0.002` (= 0.002 RVN/kB = 200_000 sat/kB). Assert `estimateSatPerKb(6) == 200_000L`. - - `@Test fun passes_target_blocks_to_lambda()`: capture int arg, call `estimateSatPerKb(12)`, assert captured == 12. - - - For each of the four test files, create the package directory and write a JUnit 4 test class. Every test uses `org.junit.Assert.*` and `org.junit.Test`, and tests that require `android.content.Context` use `androidx.test.core.app.ApplicationProvider.getApplicationContext()` (already available via `androidx.test.ext:junit` test dep; run with `org.junit.runner.RunWith(AndroidJUnit4::class)` from `androidx.test.ext.junit.runners.AndroidJUnit4`) OR Robolectric if already on the classpath — `RavencoinTxBuilderTest.kt` already runs pure JVM without Android, so check: if the Context-requiring tests cannot run in the JVM unit test flavor, use `androidx.test.ext.junit.runners.AndroidJUnit4` + `@Config(manifest = Config.NONE)` only if Robolectric is on classpath; otherwise mark the tests `@Ignore("requires Android runtime — Wave 0 scaffolding")` and document in the plan summary. Primary goal: files compile and tests are executable or ignored. - - Preferred approach (simpler): Do NOT require Context in the DAO test files. Instead, introduce an interface shim in each test file like: - ```kotlin - private interface WalletCacheStore { - fun writeState(utxos: List, assetUtxos: Map>, blockHeight: Int) - fun readState(): WalletCacheDao.CachedWalletState? - fun computeSpendableBalanceSat(utxos: List, reservedSat: Long): Long - } - ``` - and write an in-test `InMemoryStore` implementing the shim, plus a helper test that exercises `WalletCacheDao.computeSpendableBalanceSat` as a pure function (the only assertion that does NOT require SQLite). Mark the SQLite-roundtrip tests with `@Ignore("requires Android runtime — implementation in plan 30-02")` and leave the balance-subtracts-reserved pure-function tests un-ignored. The pure-function tests must FAIL with `NotImplementedError` because `WalletCacheDao.computeSpendableBalanceSat` does not yet exist — this is the valid RED state. - - Concrete: at top of WalletCacheDaoTest.kt, write: - ```kotlin - package io.raventag.app.wallet.cache - import io.raventag.app.wallet.Utxo - import io.raventag.app.wallet.AssetUtxo - import org.junit.Assert.assertEquals - import org.junit.Ignore - import org.junit.Test - - class WalletCacheDaoTest { - @Test fun balance_subtracts_reserved_never_negative() { - val utxos = listOf(Utxo(txid="a", vout=0, value=300_000_000L, height=100)) - val reserved = 500_000_000L - // WalletCacheDao.computeSpendableBalanceSat signature: (utxos, reservedSat) -> Long - val spendable = WalletCacheDao.computeSpendableBalanceSat(utxos, reserved) - assertEquals(0L, spendable) - } - @Test fun balance_subtracts_reserved_positive() { /* as in behavior */ } - @Ignore("requires Android Context — implemented by plan 30-02") - @Test fun roundtrip_preserves_utxos_and_timestamp() { /* stub body calling TODO() */ } - } - ``` - Note: `WalletCacheDao.computeSpendableBalanceSat` accepts `(List, Long)` per the inline spec — plan 30-02 MUST honor this signature. If Wave 1 decides to compute `reservedSat` internally via SQLite, expose a pure overload `fun computeSpendableBalanceSat(utxos: List, reservedSat: Long): Long` alongside. - - Verify that `android/app/build.gradle.kts` already declares `testImplementation("junit:junit:4.13.2")` or compatible and `testImplementation("com.google.code.gson:gson:2.10.1")` — it does because `RavencoinTxBuilderTest.kt` compiles. If Gson is not already on the test classpath, add `testImplementation` for it in build.gradle.kts. Do NOT add other new test deps. - - Em-dash audit: `! grep -P '\u2014' android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt android/app/src/test/java/io/raventag/app/wallet/subscription/SubscriptionParserTest.kt android/app/src/test/java/io/raventag/app/wallet/fee/FeeEstimatorTest.kt` - - - cd android && ./gradlew :app:compileConsumerDebugUnitTestKotlin -q 2>&1 | tail -20 ; test $? -eq 0 - - - - `test -f android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt` - - `test -f android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt` - - `test -f android/app/src/test/java/io/raventag/app/wallet/subscription/SubscriptionParserTest.kt` - - `test -f android/app/src/test/java/io/raventag/app/wallet/fee/FeeEstimatorTest.kt` - - `grep -q "class WalletCacheDaoTest" android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt` - - `grep -q "fun balance_subtracts_reserved_never_negative" android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt` - - `grep -q "fun roundtrip" android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt` - - `grep -q "fun insert_on_broadcast" android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt` - - `grep -q "fun cleanup_on_confirm" android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt` - - `grep -q "fun prune_stale" android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt` - - `grep -q "class SubscriptionParserTest" android/app/src/test/java/io/raventag/app/wallet/subscription/SubscriptionParserTest.kt` - - `grep -q "class FeeEstimatorTest" android/app/src/test/java/io/raventag/app/wallet/fee/FeeEstimatorTest.kt` - - `grep -q "fun fallback" android/app/src/test/java/io/raventag/app/wallet/fee/FeeEstimatorTest.kt` - - `! grep -P '\u2014' android/app/src/test/java/io/raventag/app/wallet/cache/WalletCacheDaoTest.kt android/app/src/test/java/io/raventag/app/wallet/cache/ReservedUtxoDaoTest.kt android/app/src/test/java/io/raventag/app/wallet/subscription/SubscriptionParserTest.kt android/app/src/test/java/io/raventag/app/wallet/fee/FeeEstimatorTest.kt` - - `cd android && ./gradlew :app:compileConsumerDebugUnitTestKotlin` exits 0 (compile clean; tests may reference not-yet-existing classes in interface stubs but must be resolved via top-of-file type stubs or real Wave 1 types planned for 30-02/30-03/30-04; the compile step must succeed for the plan to be considered done). - - Running `./gradlew :app:testConsumerDebugUnitTest --tests "*WalletCacheDaoTest*"` exits **non-zero** with at least one assertion failure (RED), OR all tests `@Ignore`-marked with a clear reason pointing to plan 30-02 (acceptable fallback for Context-dependent cases). - - Four test files compile.

Phrase with 13 real words (one added) throws `IllegalArgumentException`. Use a known-good BIP39 12-word phrase from BIP39 test vectors, e.g. `"abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"`. Assert `WalletManager.Companion.validateMnemonic(input)` returns normalized 12-word list (the companion `validateMnemonic` must be exposed — if it's `private`, Wave 2 plan 30-06 promotes it to `internal`). - - `@Test fun restore_forces_backup_when_wallet_non_zero_and_not_backed_up()`: construct scenario: current wallet state reports balance > 0 AND `hasBackedUpCurrentMnemonic == false`. Call the new `WalletManager.checkRestorePreconditions(currentBalanceSat = 100_000_000L, hasBackedUp = false)` method (stub signature; to be added in 30-06). Assert it throws `BackupRequiredException`. Call with `hasBackedUp = true` → returns Unit (no throw). Call with `currentBalanceSat = 0L, hasBackedUp = false` → no throw. - - `@Test fun hmac_integrity_mismatch_throws()`: call `WalletManager.verifySeedHmac(seed = byteArrayOf(1,2,3), storedTag = byteArrayOf(9,9,9))` (stub signature; to be added in 30-06). Assert throws `IntegrityException`. Same call with a correct HMAC returns true. - - `@Test fun key_invalidated_routes_to_restore()`: call `WalletManager.wrapKeystoreException { throw android.security.keystore.KeyPermanentlyInvalidatedException() }` (stub helper; 30-06 implements as `internal inline fun wrapKeystoreException(block: () -> T): T`). Assert rethrows as `KeystoreInvalidatedException` with the original as `cause`. Generic `IOException` is NOT wrapped. - - Because WalletManager requires Context for the real init flow, any test that exercises Keystore must be `@Ignore("requires Android runtime — instrumented test")`. Pure-logic helpers (`validateMnemonic`, `checkRestorePreconditions`, `verifySeedHmac`, `wrapKeystoreException`) must be authored so they do NOT depend on Context and can run in pure JVM unit tests. - - RavencoinTxBuilderTest.kt extension (keep all existing tests): - - `@Test fun multiAddressSend_change_to_fresh_address()`: construct (or reuse existing fixtures in the file) a multi-address send where the builder is passed `changeAddress = "FRESH_ADDR_0xABC"`. Parse the built raw tx and assert: at least one output has `scriptPubKey` matching `OP_DUP OP_HASH160 OP_EQUALVERIFY OP_CHECKSIG` (i.e. a P2PKH output to that address) AND the sum of outputs to any other external address does NOT include the cycled amount. If the existing test file already has a helper like `buildMultiAddressSend(...)`, call it; otherwise construct the inputs/outputs manually matching the existing test harness. The exact existing helper to reuse MUST be located during execution by reading `RavencoinTxBuilderTest.kt` top-to-bottom — use the same private `ECKey` fixture keys and `TestContext` fake if present. - - - WalletManagerMnemonicTest: create at `android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt`. Use pure JUnit 4: - ```kotlin - package io.raventag.app.wallet - import org.junit.Assert.* - import org.junit.Test - import org.junit.Ignore - import io.raventag.app.wallet.BackupRequiredException - import io.raventag.app.wallet.IntegrityException - import io.raventag.app.wallet.KeystoreInvalidatedException - - class WalletManagerMnemonicTest { - private val validPhrase = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about" - - @Test fun validateMnemonic_rejects_padding() { - val normalized = WalletManager.validateMnemonic("$validPhrase \n\t") - assertEquals(12, normalized.size) - assertEquals("about", normalized.last()) - assertEquals(12, WalletManager.validateMnemonic(" $validPhrase ").size) - val thirteen = "$validPhrase apple" - try { WalletManager.validateMnemonic(thirteen); fail("expected throw") } catch (_: IllegalArgumentException) { /* ok */ } - } - - @Test fun restore_forces_backup_when_wallet_non_zero_and_not_backed_up() { - try { - WalletManager.checkRestorePreconditions(currentBalanceSat = 100_000_000L, hasBackedUp = false) - fail("expected BackupRequiredException") - } catch (_: BackupRequiredException) { /* ok */ } - WalletManager.checkRestorePreconditions(currentBalanceSat = 100_000_000L, hasBackedUp = true) - WalletManager.checkRestorePreconditions(currentBalanceSat = 0L, hasBackedUp = false) - } - - @Test fun hmac_integrity_mismatch_throws() { - val seed = byteArrayOf(1, 2, 3) - val goodTag = WalletManager.computeSeedHmacForTest(seed, keyBytes = ByteArray(32) { it.toByte() }) - WalletManager.verifySeedHmac(seed, goodTag, keyBytes = ByteArray(32) { it.toByte() }) - try { - WalletManager.verifySeedHmac(seed, byteArrayOf(9, 9, 9), keyBytes = ByteArray(32) { it.toByte() }) - fail("expected IntegrityException") - } catch (_: IntegrityException) { /* ok */ } - } - - @Test fun key_invalidated_routes_to_restore() { - try { - WalletManager.wrapKeystoreException { - throw android.security.keystore.KeyPermanentlyInvalidatedException() - } - fail("expected KeystoreInvalidatedException") - } catch (e: KeystoreInvalidatedException) { - assertTrue(e.cause is android.security.keystore.KeyPermanentlyInvalidatedException) - } - // IOException should NOT be wrapped - try { - WalletManager.wrapKeystoreException { throw java.io.IOException("transient") } - fail("expected passthrough IOException") - } catch (e: java.io.IOException) { assertEquals("transient", e.message) } - } - } - ``` - NOTE: `WalletManager.computeSeedHmacForTest` is a test-only helper that plan 30-06 MUST add (it uses the same BouncyCastle `HMac(SHA256Digest())` as the production helper but takes the key as raw bytes instead of fetching from Keystore). Signal this in the plan summary. - - RavencoinTxBuilderTest extension: read the current file fully to understand its fixture style. Append a new `@Test fun multiAddressSend_change_to_fresh_address()` at the bottom of the existing class (do NOT create a second class). Reuse any existing private helper to call `buildAndSignMultiAddressSend` with a known `changeAddress`. Parse outputs; assert the P2PKH output to `changeAddress` exists and carries the expected cycled value. The test MUST compile even if it fails — use explicit imports. If the existing test file uses extension functions or companion helpers to construct fake UTXOs, reuse them. - - Em-dash audit: `! grep -P '\u2014' android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt android/app/src/test/java/io/raventag/app/wallet/RavencoinTxBuilderTest.kt`. - - - cd android && ./gradlew :app:compileConsumerDebugUnitTestKotlin -q 2>&1 | tail -30 ; test $? -eq 0 - - - - `test -f android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "class WalletManagerMnemonicTest" android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "fun validateMnemonic_rejects_padding" android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "fun restore_forces_backup" android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "fun hmac_integrity_mismatch_throws" android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "fun key_invalidated_routes_to_restore" android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt` - - `grep -q "multiAddressSend_change_to_fresh_address" android/app/src/test/java/io/raventag/app/wallet/RavencoinTxBuilderTest.kt` - - `! grep -P '\u2014' android/app/src/test/java/io/raventag/app/wallet/WalletManagerMnemonicTest.kt android/app/src/test/java/io/raventag/app/wallet/RavencoinTxBuilderTest.kt` - - `cd android && ./gradlew :app:compileConsumerDebugUnitTestKotlin` exits 0. - - `cd android && ./gradlew :app:testConsumerDebugUnitTest --tests "*WalletManagerMnemonicTest*"` exits NON-zero (RED state because 30-06 has not implemented the helpers yet) — or tests fail with `NoSuchMethodError`/`Unresolved reference` at compile time only if Wave 0 uses stub type declarations; we require the types (`BackupRequiredException`, `IntegrityException`, `KeystoreInvalidatedException`) to be declared minimally here (see note below) so the file compiles. - - - Both test files compile. WalletManagerMnemonicTest fails RED (methods not implemented yet). The RavencoinTxBuilderTest extension test either fails RED (no `changeAddress` guarantee yet) or passes GREEN (existing builder already satisfies it — acceptable since D-17 is already implemented per RESEARCH.md L92; the test then serves as a regression guard). - - **Compile-bootstrap note (critical for downstream):** To make `WalletManagerMnemonicTest.kt` compile before plan 30-06 runs, this task MUST also create a minimal stub file `android/app/src/main/java/io/raventag/app/wallet/WalletExceptions.kt` containing ONLY the exception class declarations: - ```kotlin - package io.raventag.app.wallet - class BackupRequiredException(msg: String = "backup required before restore") : RuntimeException(msg) - class IntegrityException(msg: String = "seed HMAC mismatch") : RuntimeException(msg) - class KeystoreInvalidatedException(cause: Throwable? = null) : RuntimeException("keystore invalidated", cause) - ``` - Plan 30-06 will leave this file in place (adding methods to `WalletManager`, not moving the exceptions). Add this file path to `files_modified` acceptance criteria: - - `test -f android/app/src/main/java/io/raventag/app/wallet/WalletExceptions.kt` - - `grep -q "class BackupRequiredException" android/app/src/main/java/io/raventag/app/wallet/WalletExceptions.kt` - - `grep -q "class KeystoreInvalidatedException" android/app/src/main/java/io/raventag/app/wallet/WalletExceptions.kt` - - Additionally, `WalletManager` MUST gain four no-op / throwing helper stubs in this plan (plan 30-06 replaces the bodies with real implementations). Add to `WalletManager.kt` companion object: - ```kotlin - companion object { - @JvmStatic fun validateMnemonic(input: String): List = TODO("30-06") - @JvmStatic fun checkRestorePreconditions(currentBalanceSat: Long, hasBackedUp: Boolean) { TODO("30-06") } - @JvmStatic fun computeSeedHmacForTest(seed: ByteArray, keyBytes: ByteArray): ByteArray = TODO("30-06") - @JvmStatic fun verifySeedHmac(seed: ByteArray, tag: ByteArray, keyBytes: ByteArray) { TODO("30-06") } - @JvmStatic inline fun wrapKeystoreException(block: () -> T): T = TODO("30-06") - } - ``` - Only add stubs that do NOT already exist. If `validateMnemonic` already exists at line ~818 (per RESEARCH.md Pitfall 7), do not shadow it; instead, the test references that existing method — update the signature note in the plan summary. Add acceptance criterion: `grep -q "fun validateMnemonic" android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt`. - - The net effect: the test compiles, fails RED on TODO/assertion, and plans 30-02/30-03/30-04/30-06 turn tests green incrementally. -

-## Performance - -- **Completed:** 2026-04-21 -- **Commits:** 2 -- **Files created:** 3 -- **Files modified:** 2 - -## Accomplishments - -- Extracted `TofuTrustManager` from `RavencoinPublicNode` into its own reusable internal class with the existing dual-layer fingerprint cache behavior intact -- Added `subscribeScripthashRpc(address)` and `estimateFeeRvnPerKb(targetBlocks)` wrappers to `RavencoinPublicNode` -- Promoted `addressToScripthash(address)` to `internal` visibility for subscription reuse -- Implemented `ScripthashEvent` as the event contract for subscription notifications and failure states -- Replaced the Wave 0 parser stub with a real `SubscriptionParser.parseLine()` implementation that routes response, notification, and unknown frames -- Added `SubscriptionManager` with persistent TLS socket lifecycle, per-request id matching, 60s ping heartbeat, and `SharedFlow` API -

sealed event model: `StatusChanged`, `ConnectionLost`, `AllNodesDown`, `PingTimeout` -- `android/app/src/main/java/io/raventag/app/wallet/subscription/SubscriptionManager.kt` - persistent ElectrumX subscription session with reader loop, heartbeat loop, and `SharedFlow` - -### Modified - -- `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt` - removed inline `TofuTrustManager`, added subscribe/estimatefee wrappers, exposed `addressToScripthash` as `internal` -- `android/app/src/main/java/io/raventag/app/wallet/subscription/SubscriptionParser.kt` - implemented Wave 0 contract for JSON-RPC frame routing - -## Behavior Delivered - -- `SubscriptionParser` now returns: - - `Parsed.Response(id, result)` when a frame contains an integer `id` - - `Parsed.Notification(scripthash, status)` for `blockchain.scripthash.subscribe` pushes - - `Parsed.Unknown(raw)` for malformed or unsupported frames -- `SubscriptionManager.start(addresses)`: - - opens one TLS socket to the first reachable ElectrumX server - - performs `server.version` handshake - - subscribes every wallet address after converting it to scripthash - - starts a reader coroutine that routes responses via request id and notifications via `ScripthashEvent.StatusChanged` - - starts a 60-second `server.ping` heartbeat to detect zombie sockets -- `SubscriptionManager.stop()` cancels the scope, closes the socket, and clears pending callbacks -- If every server fails on startup, the manager emits `AllNodesDown` -- If the socket dies or read loop fails, the manager emits `ConnectionLost` -- If the heartbeat times out, the manager emits `PingTimeout` - -## Test / Validation Notes - -- Commit `bd7ba0c` records that all 6 Wave 0 `SubscriptionParserTest` tests were GREEN after parser implementation -- `0ad9de9` fixed unresolved `coroutineContext` and `isActive` references in `SubscriptionManager`, which was required for downstream plan `30-04` compilation -- This summary was generated from repository state, planning docs, and commit history; Gradle tests were not re-run during summary generation - -## Deviations from Plan - -### Notable implementation detail - -- `SubscriptionManager.kt` landed in the follow-up fix commit `0ad9de9` instead of the main feature commit `bd7ba0c`.

Returns the status hash (or null). Used only for the *one-shot* subscribe on the foreground polling path or the WorkManager worker; the long-lived socket in `SubscriptionManager` uses its own path. Purpose: give `WalletPollingWorker` (plan 30-08) a way to capture the current status for background diff. - - `RavencoinPublicNode.estimateFeeRvnPerKb(targetBlocks: Int): Double` — wrapper around `callWithFailover("blockchain.estimatefee", listOf(targetBlocks))`. Returns the JSON number as Double. Returns -1.0 on `JsonNull`. Throws the underlying exception on RPC error so `FeeEstimator` (plan 30-04) can catch it and fall back. - - - **Step 1 — Extract TofuTrustManager**: - Read `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt` lines 1612-1652. Copy the entire `TofuTrustManager` class (including companion object if any) into a new file: - - ```kotlin - // android/app/src/main/java/io/raventag/app/wallet/TofuTrustManager.kt - package io.raventag.app.wallet - - import android.content.Context - import io.raventag.app.security.TofuFingerprintDao - import java.security.MessageDigest - import java.security.cert.CertificateException - import java.security.cert.X509Certificate - import javax.net.ssl.X509TrustManager - - internal class TofuTrustManager( - private val context: Context, - private val host: String - ) : X509TrustManager { - // ... paste body from RavencoinPublicNode.kt:1612-1652 ... - } - ``` - - Use the Read tool to get the exact source at lines 1612-1652 plus any companion/helper it references, then paste into the new file. - - **Step 2 — Edit RavencoinPublicNode.kt**: - - Delete the `private class TofuTrustManager(...)` declaration at the original location. - - If there was a companion-level constant or helper only used by TofuTrustManager, move it to the new file (or keep it and change the import). Minimize blast radius. - - At the top of `RavencoinPublicNode.kt` imports, add `import io.raventag.app.wallet.TofuTrustManager` (if it's in the same package, no import needed; the new file IS in `io.raventag.app.wallet`, so no import is needed — just reference `TofuTrustManager` directly). - - Verify every existing `TofuTrustManager(...)` instantiation still compiles. - - **Step 3 — Add RPC wrappers**: - Append two new suspend functions to `RavencoinPublicNode.kt`, inside the class body (NOT the companion), next to the existing `getBalance` / `getUtxos` methods so readers find them together: - - ```kotlin - /** - * D-05 support — subscribes to a scripthash and returns the current status hash. - * Uses the one-shot RPC socket; the foreground-session long-lived socket lives in - * [io.raventag.app.wallet.subscription.SubscriptionManager]. - */ - fun subscribeScripthashRpc(address: String): String? { - val scripthash = addressToScripthash(address) - val result = callWithFailover("blockchain.scripthash.subscribe", listOf(scripthash)) - return if (result.isJsonNull) null else result.asString - } - - /** - * D-22 support — calls blockchain.estimatefee with a block target and returns - * the raw RVN/kB number. Returns -1.0 when the server returns null. Callers - * (FeeEstimator) are responsible for the static-fallback policy. - */ - fun estimateFeeRvnPerKb(targetBlocks: Int): Double { - val result = callWithFailover("blockchain.estimatefee", listOf(targetBlocks)) - return if (result.isJsonNull) -1.0 else result.asDouble - } - ``` - - Note: `callWithFailover` already exists as a `private` helper. If it returns `JsonElement`, above signatures are correct. If it is synchronous (not suspend), keep the wrappers synchronous too — the existing pattern in `getBalance` is the authoritative template. Do NOT suspend-ify if not already suspend. - - **Step 4 — ScripthashEvent.kt**: - ```kotlin - // android/app/src/main/java/io/raventag/app/wallet/subscription/ScripthashEvent.kt - package io.raventag.app.wallet.subscription - - sealed class ScripthashEvent { - /** - * ElectrumX pushed a status-hash change for [scripthash]. [newStatus] may be null - * when the server reports "no history". Caller MUST re-fetch balance/utxo/history - * per RESEARCH.md §Architecture Pattern 1: subscription only says "something changed". - */ - data class StatusChanged(val scripthash: String, val newStatus: String?) : ScripthashEvent() - /** The session socket died (network transition, server reset). */ - data object ConnectionLost : ScripthashEvent() - /** All fallback servers refused connection. D-12 red pill. */ - data object AllNodesDown : ScripthashEvent() - /** Ping did not return within 60s — socket is a zombie (Pitfall 2). */ - data object PingTimeout : ScripthashEvent() - } - ``` - - **Step 5 — SubscriptionParser.kt**: - ```kotlin - // android/app/src/main/java/io/raventag/app/wallet/subscription/SubscriptionParser.kt - package io.raventag.app.wallet.subscription - - import com.google.gson.JsonElement - import com.google.gson.JsonNull - import com.google.gson.JsonParser - import com.google.gson.JsonSyntaxException - - object SubscriptionParser { - sealed class Parsed { - data class Response(val id: Int, val result: JsonElement?) : Parsed() - data class Notification(val scripthash: String, val status: String?) : Parsed() - data class Unknown(val raw: String) : Parsed() - } - - fun parseLine(line: String): Parsed { - if (line.isBlank()) return Parsed.Unknown(line) - val obj = try { - JsonParser.parseString(line).asJsonObject - } catch (_: JsonSyntaxException) { return Parsed.Unknown(line) } - catch (_: IllegalStateException) { return Parsed.Unknown(line) } - - // id present → response - val idEl = obj.get("id") - if (idEl != null && !idEl.isJsonNull) { - val id = try { idEl.asInt } catch (_: Exception) { return Parsed.Unknown(line) } - val result: JsonElement? = obj.get("result").takeUnless { it == null || it.isJsonNull } - return Parsed.Response(id = id, result = result) - } - - // server notification - val method = obj.get("method")?.takeUnless { it.isJsonNull }?.asString ?: return Parsed.Unknown(line) - if (method == "blockchain.scripthash.subscribe") { - val params = obj.getAsJsonArray("params") ?: return Parsed.Unknown(line) - if (params.size() < 1) return Parsed.Unknown(line) - val sh = params.get(0).takeUnless { it.isJsonNull }?.asString ?: return Parsed.Unknown(line) - val status = if (params.size() >= 2 && !params.get(1).isJsonNull) params.get(1).asString else null - return Parsed.Notification(scripthash = sh, status = status) - } - return Parsed.Unknown(line) - } - } - ``` - - Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/wallet/TofuTrustManager.kt android/app/src/main/java/io/raventag/app/wallet/subscription/ScripthashEvent.kt android/app/src/main/java/io/raventag/app/wallet/subscription/SubscriptionParser.kt`.

The fee override input uses `KeyboardType.Decimal` and `toDoubleOrNull()` parsing, which safely handles non-numeric input by returning null (keeping the estimated fee). The sanity cap at 100_000_000 sat/kB (1.0 RVN/kB) mitigates T-30-NET-04 from the plan's threat model. - -## Self-Check: PASSED - -All 5 key files exist on disk. All 3 commit hashes found in git log.

The cleanest design — drop the dual-constructor idea and instead use: - ```kotlin - class FeeEstimator(private val estimateProvider: suspend (Int) -> Double) { - constructor(node: RavencoinPublicNode) : this(estimateProvider = { t -> - withContext(Dispatchers.IO) { node.estimateFeeRvnPerKb(t) } - }) - // ... rest as above ... - } - ``` - That's one primary constructor (the lambda) + one secondary (taking the node). Update the Wave 0 test file IF needed so it instantiates via the lambda constructor; per 30-01 it already does. Verify by reading `FeeEstimatorTest.kt` and adjust the constructor mode to match. - - **AppStrings.kt** — append new keys to both `stringsEn` and `stringsIt`. Use Grep to locate the existing map declarations and add keys in alphabetical / logical order: - Keys to add (EN): - - `sendFeeLabel = "Fee"` (used in: `Fee: %1$s RVN · ~6 blocks`) - - `sendFeeTarget = "~6 blocks"` - - `sendFeeEditLabel = "Edit fee"` - - `sendFeeOverrideHint = "Custom fee (RVN/kB)"` - - `sendFeeEstimateUnavailable = "Fee estimate unavailable.

Typing updates the held `satPerKbOverride` state. - - Above the fee row: if `usedFallback == true`, show a text `"Fee estimate unavailable. Using 0.01 RVN/kB fallback."` (EN) / IT equivalent in `RavenOrange bodySmall`. - - On Send button press, the ViewModel uses the override value if any, else the estimator result, to compute the fee, pass to `sendRvnLocal` (or asset equivalent). - - When the user cancels the dialog, any override is discarded. - - The estimator call is made LAZILY on dialog open (not on screen open), so it reflects fresh network state. - - - Strategy: these screens already exist and already show a send confirm flow (Phase 20 D-07). The change is additive. For both files: - - 1. Read the existing file top-to-bottom. Locate the confirmation `AlertDialog` composable (Phase 20 pattern). - 2. Add a `fun buildFeeSection(...)` private composable in the same file that renders: - - conditional warning line (bodySmall, RavenOrange) when `usedFallback == true` - - a `Row` with the fee label (bodySmall) and an `IconButton` (Edit icon, RavenOrange) - - when expanded: an `OutlinedTextField` with singleLine=true, keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Decimal) - 3. In the dialog body, insert this section above the existing confirm/cancel buttons. - 4. Hoist the fee state into a `rememberSaveable` at the screen top: `var feeSatPerKb by remember { mutableStateOf(null) }`; `var usedFallback by remember { mutableStateOf(false) }`; `var feeOverride by remember { mutableStateOf(null) }`. - 5. On confirm-dialog opening (e.g., `LaunchedEffect(showConfirmDialog) { if (showConfirmDialog) { ... }}`): call `FeeEstimator(node).estimateSatPerKbWithSource(6)` from a CoroutineScope tied to the dialog, update `feeSatPerKb` and `usedFallback`. - 6. Pass the effective fee (override if set, else estimate, else FALLBACK) to the existing send handler. - - Do NOT touch the send-builder logic itself in this plan — pass the new fee rate into the existing transaction-building call (matching whatever argument `sendRvnLocal` / asset-transfer function accepts). If that function currently expects `sat/byte` and we have `sat/kB`: divide by 1000 at the call site. Document which unit the existing send code uses in the plan summary so plan 30-05 can align. - - Concrete snippet to insert (shape, adapt imports): - ```kotlin - @Composable - private fun FeeSection( - feeSatPerKb: Long?, - usedFallback: Boolean, - overrideText: String, - onOverrideChange: (String) -> Unit, - onEditToggle: () -> Unit, - editOpen: Boolean - ) { - val strings = LocalStrings.current - Column { - if (usedFallback) { - Text( - text = strings.sendFeeEstimateUnavailable, - style = MaterialTheme.typography.bodySmall, - color = RavenOrange, - modifier = Modifier.padding(bottom = 4.dp) - ) - } - Row(verticalAlignment = Alignment.CenterVertically) { - val feeRvn = (feeSatPerKb ?: FeeEstimator.FALLBACK_SAT_PER_KB) / 1e8 - Text( - text = "${strings.sendFeeLabel}: %.8f RVN · ${strings.sendFeeTarget}".format(feeRvn), - style = MaterialTheme.typography.bodySmall, - color = RavenMuted, - modifier = Modifier.weight(1f) - ) - IconButton(onClick = onEditToggle, modifier = Modifier.size(36.dp)) { - Icon(Icons.Default.Edit, contentDescription = strings.sendFeeEditLabel, tint = RavenOrange) - } - } - if (editOpen) { - OutlinedTextField( - value = overrideText, - onValueChange = onOverrideChange, - label = { Text(strings.sendFeeOverrideHint) }, - singleLine = true, - keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Decimal), - modifier = Modifier.fillMaxWidth() - ) - } - } - } - ``` - - Transfer screen: same snippet pattern, same strings, same FeeEstimator call.

This task replaces each with the real implementation and extends the existing instance methods that touch Keystore. - - 1) `validateMnemonic(input: String): List` — normalize whitespace via `input.trim().split(Regex("\\s+"))`; reject counts not in `setOf(12, 15, 18, 21, 24)` with `IllegalArgumentException("invalid word count: ${words.size}")`; run the existing BIP39 checksum logic on the normalized list (reuse whatever helper currently lives in WalletManager, e.g. `bip39ChecksumValid(words)`; if that helper is private, invoke it via the companion object's internal scope). Return the normalized `List` on success. - - 2) `checkRestorePreconditions(currentBalanceSat: Long, hasBackedUp: Boolean)` — if `currentBalanceSat > 0L && !hasBackedUp` throw `BackupRequiredException("Current wallet has $currentBalanceSat sat and has not been backed up")`. Otherwise return Unit. - - 3) `computeSeedHmacForTest(seed: ByteArray, keyBytes: ByteArray): ByteArray` — use BouncyCastle `HMac(SHA256Digest())`: - ```kotlin - val mac = org.bouncycastle.crypto.macs.HMac(org.bouncycastle.crypto.digests.SHA256Digest()) - mac.init(org.bouncycastle.crypto.params.KeyParameter(keyBytes)) - mac.update(seed, 0, seed.size) - val out = ByteArray(mac.macSize) - mac.doFinal(out, 0) - return out - ``` - Both `computeSeedHmacForTest` and the production `computeSeedHmac(seed)` (instance method) share this logic. The test-only variant takes the key as bytes for determinism; the production variant fetches the HMAC key from the Keystore (see step 5 below). - - 4) `verifySeedHmac(seed: ByteArray, tag: ByteArray, keyBytes: ByteArray)` — compute HMAC and compare with constant-time `java.security.MessageDigest.isEqual(expected, tag)`; on mismatch throw `IntegrityException("seed HMAC mismatch")`. Return Unit on match. - - 5) `wrapKeystoreException(block: () -> T): T` — the inline function catches ONLY `android.security.keystore.KeyPermanentlyInvalidatedException` (and nothing else) and rethrows as `KeystoreInvalidatedException(cause = e)`. All other exceptions pass through unchanged. Because it is inline + reified? No — it is `inline fun ` only (no reified). Place on `WalletManager.Companion` per Wave 0 contract. - - Instance-level changes: - - 6) HMAC key provisioning — introduce a second Keystore AES-GCM key, alias `raventag_wallet_hmac_key` (distinct from the existing alias). Use the same spec as the existing `getOrCreateAndroidKey()` minus any biometric binding (StrongBox when available, `setUnlockedDeviceRequired(true)` on API 28+). This key is used to derive 32 raw key bytes via AES-GCM-encrypting a fixed 32-byte input (or simpler: use HKDF via BouncyCastle — but the RESEARCH A9 / Don't Hand-Roll approach is "use a second Keystore-wrapped AES-GCM key as the HMAC key material"). Implement this way: - - On first use, generate 32 random bytes, AES-GCM-encrypt them with the existing mnemonic Keystore key, and store the ciphertext + IV in the `raventag_wallet` prefs under key `KEY_HMAC_MATERIAL_CT` / `KEY_HMAC_MATERIAL_IV`. - - To compute HMAC, decrypt the stored material to get 32 raw bytes, use them as the BouncyCastle HMAC key, then zero-fill the local `ByteArray` after use. - - Rationale: avoids the trap of exposing a Keystore-bound HMAC key through `javax.crypto.Mac`, which requires a key that can be extracted from the Keystore (AES can't be). BouncyCastle `HMac` takes raw bytes — we bridge through the decrypt step. - - 7) Store/verify HMAC in the existing `storeSeed(seed: ByteArray)` / `getSeed()` / `storeMnemonic(mnemonic: String)` / `getMnemonic()` methods: - - After `encrypt(seed, iv)` produces ciphertext, compute `hmac = computeSeedHmac(seed)` (production variant) and store Base64(hmac) under `KEY_SEED_HMAC`. - - In `getSeed()`, after decrypt, compute HMAC of the plaintext, verifySeedHmac against the stored tag; on mismatch throw `IntegrityException` (no attacker has a usable wallet). - - Same for mnemonic under `KEY_MNEMONIC_HMAC`. - - 8) Wrap every `cipher.doFinal(...)` call site in `wrapKeystoreException { ... }`. Concretely: `getSeed()`, `getMnemonic()`, `storeSeed()` (doFinal on encrypt), `storeMnemonic()`. The wrap converts `KeyPermanentlyInvalidatedException` into `KeystoreInvalidatedException` which the UI surfaces as the "Device security changed" dialog. - - 9) BIP39 whitespace normalization — the existing `validateMnemonic` (if any) at the ~line 818 region per RESEARCH Pitfall 7 must use `input.trim().split(Regex("\\s+"))` before BIP39 processing. The companion shim replaces/wraps the existing instance / companion variant. Concretely: if the existing signature is `fun validateMnemonic(phrase: String): Boolean`, create a new `@JvmStatic fun validateMnemonic(input: String): List` that calls the existing boolean validator on the normalized list and returns the normalized list on success / throws on failure. Retain the boolean variant as a thin shim for any existing callers; update all call sites to use the new list-returning variant where the normalized list is needed. - - 10) `restoreFromMnemonic(phrase: String)` — BEFORE any Keystore rewrite: - - Compute `currentBalanceSat` via `ReservedUtxoDao.sumReservedSat()` + latest cached balance from `WalletCacheDao.readState()?.balanceSat ?: 0L` (or read from SharedPreferences "wallet_poll.poll_rvn_sat" if the reliability DB is not yet initialized). A simple proxy is acceptable: read the last-known balance from the wallet state cache. - - Read `hasBackedUp = prefs.getBoolean("backup_completed", false)`. - - Call `checkRestorePreconditions(currentBalanceSat, hasBackedUp)`. On throw, propagate `BackupRequiredException` to the UI. - - Then validate the phrase via the new `validateMnemonic`; on failure propagate `IllegalArgumentException`. - - Then proceed with the existing restore logic. - - 11) Remove any in-memory mnemonic cache (D-16). AUDIT: search WalletManager.kt for properties of type `String?`, `ByteArray?`, `CharArray?` that hold decrypted mnemonic/seed. Candidates: `private var cachedMnemonic: String? = null`, `private val mnemonicCache: ...`, any `companion object` field that shadows the decrypted value. DELETE them. Ensure every caller re-decrypts via `getMnemonic()` / `getSeed()`. Add acceptance criterion: `! grep -nE '(cachedMnemonic|mnemonicCache|decryptedMnemonic|plaintextSeed|seedCache)' android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt`. - - 12) New instance method `suspend fun revealMnemonicCharsWithBiometric(gate: BiometricGate): CharArray`: - - Build the Cipher in `DECRYPT_MODE` with the Keystore key + stored IV (re-use the existing `decrypt(...)` scaffolding BUT without calling `doFinal` — stop after `cipher.init`). - - Catch `KeyPermanentlyInvalidatedException` at init time via `wrapKeystoreException`. - - Call `gate.decryptWithBiometric(cipher, storedMnemonicCiphertext, R.string.biometricRevealTitle, R.string.biometricRevealSubtitle)` → ByteArray. - - Verify HMAC on the decrypted plaintext. - - Convert `ByteArray` (UTF-8) to `CharArray` via `String(plaintext, Charsets.UTF_8).toCharArray()`. Immediately zero-fill the intermediate `ByteArray` via `Arrays.fill(plaintext, 0)`. - - Return the `CharArray`. **Caller** (MnemonicExporter / UI) is responsible for zero-filling the returned CharArray after display. - - **Em-dash audit** on touched file: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt`. - - - Read `WalletManager.kt` fully (~2102 lines per RESEARCH). Identify these landmarks: - - Existing `encrypt(bytes: ByteArray): Pair` / `decrypt(enc: ByteArray, iv: ByteArray): ByteArray` - - Existing `getOrCreateAndroidKey(): SecretKey` - - Existing `storeSeed`, `getSeed`, `storeMnemonic`, `getMnemonic` methods - - Existing `validateMnemonic` (if present) at ~line 818 - - Existing `restoreFromMnemonic` entry point - - Existing SharedPreferences file name (`raventag_wallet`) and key constants - - Make minimal surgical edits per the behavior section. Rules of engagement: - - Do NOT reorganize existing methods. Add new helpers in a single block at the bottom of the class (and in the companion object block) to minimize diff size. - - Do NOT change existing method signatures except where the behavior section explicitly requires (the new `validateMnemonic` companion is a NEW signature; retain the old boolean one as a thin shim if it exists). - - Do NOT touch `RavencoinTxBuilder.kt` (D-17 hard rule). - - Companion block replacement (replace the five Wave 0 TODOs): - ```kotlin - companion object { - // --- Existing helpers, do not delete --- - // ...

Kept as a separate object so UI code does not import WalletManager directly for reveal (single surface area for future hardening like biometric-bound delete, etc.). - - - Create `android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt`: - ```kotlin - package io.raventag.app.security - - import io.raventag.app.wallet.WalletManager - - /** - * D-13 + D-15 + D-16: reveal the mnemonic as a CharArray. - * - * Caller is responsible for zero-filling the returned CharArray after display. - * Typical pattern: - * ``` - * MnemonicExporter.revealMnemonic(gate, wm).onSuccess { chars -> - * try { renderWords(chars) } finally { java.util.Arrays.fill(chars, '\u0000') } - * } - * ``` - */ - object MnemonicExporter { - suspend fun revealMnemonic( - gate: BiometricGate, - wm: WalletManager - ): Result = runCatching { wm.revealMnemonicCharsWithBiometric(gate) } - } - ``` - - Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt`. - - - cd android && ./gradlew :app:compileConsumerDebugKotlin -q 2>&1 | tail -15 - - - - `test -f android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt` - - `grep -q "object MnemonicExporter" android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt` - - `grep -q "suspend fun revealMnemonic" android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt` - - `grep -q "Result" android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt` - - `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt` - - `cd android && ./gradlew :app:compileConsumerDebugKotlin` exits 0. - - MnemonicExporter compiles, returns Result, delegates to WalletManager.revealMnemonicCharsWithBiometric. - - - - Task 4: Extend MnemonicBackupScreen with biometric cover card + FLAG_SECURE + EN/IT strings - - android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt, - android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt - - - @.planning/phases/30-wallet-reliability/30-UI-SPEC.md#L303-L309, - @.planning/phases/30-wallet-reliability/30-UI-SPEC.md#L144-L207, - @.planning/phases/30-wallet-reliability/30-RESEARCH.md#L838-L845, - @android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt, - @android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt, - @android/app/src/main/java/io/raventag/app/security/BiometricGate.kt, - @android/app/src/main/java/io/raventag/app/security/MnemonicExporter.kt - - - Before the current 12/24-word grid becomes visible: - 1. Set `window.setFlags(WindowManager.LayoutParams.FLAG_SECURE, FLAG_SECURE)` on enter; clear on dispose. Implemented via `DisposableEffect(Unit)`. - 2. Show a covering card ("RavenCard", 16dp padding, `RoundedCornerShape(12.dp)`, `1dp RavenBorder`) containing: - - `Icons.Default.Fingerprint` 24dp `RavenOrange` - - Heading `strings.mnemonicBiometricCoverTitle` (EN "Authenticate to reveal phrase" / IT "Autenticati per mostrare la frase") in `titleSmall` SemiBold white - - Body `strings.mnemonicBiometricCoverBody` (EN "Use your fingerprint, face, or PIN to display the recovery phrase.

Chi la vede può rubare i tuoi fondi.") in `bodyMedium` RavenMuted - - Primary CTA button `Button(... containerColor=RavenOrange)` label `strings.mnemonicRevealCta` (EN "Reveal phrase" / IT "Mostra frase") - 3. On CTA tap, launch in composition coroutine scope: - - Acquire `activity = LocalContext.current as? FragmentActivity` — if null, show snackbar "Biometric unavailable". - - `val gate = BiometricGate(activity)` - - `MnemonicExporter.revealMnemonic(gate, wm)` — use the `wm` WalletManager instance already injected (existing plumbing — inspect current screen to identify). - - onSuccess: set `revealed = chars` state, UI flips to show the word grid (existing grid reads from `revealed`). Register a cleanup: when the screen leaves composition OR the user taps "Hide", `Arrays.fill(chars, '\u0000')` and `revealed = null`. - - onFailure(BiometricCancelledException): snackbar `strings.authCanceledSnackbar` (EN "Authentication canceled" / IT "Autenticazione annullata"). - - onFailure(KeystoreInvalidatedException): navigate out of this screen AND surface the top-level "Device security changed" error dialog (WalletScreen handles this via a `oneTimeError` flow — pass it up via `onKeystoreInvalidated` callback parameter to the screen). - - onFailure(any other): snackbar `strings.mnemonicRevealFailed` (EN "Could not reveal phrase. Try again." / IT "Impossibile mostrare la frase. Riprova.") - - 4. After the grid displays, keep the existing "Copy all" (`RavenOrange`) and "I've saved it" (`RavenOrange`) buttons. Existing auto-erase-clipboard-after-60s behavior is preserved. - - 5. On tapping "I've saved it" — flip SharedPreferences flag `backup_completed = true` (scoped to the current wallet). This unblocks restore-over-wallet per D-14 + Task 2 `checkRestorePreconditions`. - - AppStrings.kt additions (EN + IT verbatim from UI-SPEC Copywriting Contract): - ```kotlin - // stringsEn block - mnemonicBiometricCoverTitle = "Authenticate to reveal phrase" - mnemonicBiometricCoverBody = "Use your fingerprint, face, or PIN to display the recovery phrase.

Locate `stringsEn = AppStrings().apply { ... }` block (~line 393) and the `stringsIt = AppStrings().apply { ... }` block (~line 608). Add the EN/IT entries listed in ``. Ensure the corresponding properties are declared on `class AppStrings` near the top of the file. For each new key, check that no em dash appears. - - 2) Open `MnemonicBackupScreen.kt`. Identify: - - The screen's root `@Composable` (likely `fun MnemonicBackupScreen(...)`). - - The WalletManager injection path (field, parameter, or `remember { WalletManager(context) }` pattern). - - The existing words-grid layout. - - 3) At the top of the composable, insert the `DisposableEffect(Unit)` FLAG_SECURE block listed in ``. - - 4) Replace the current words-grid entry condition so that the grid renders only when `revealed != null`. Introduce: - ```kotlin - var revealed: CharArray? by rememberSaveable(stateSaver = null as? androidx.compose.runtime.saveable.Saver) - { mutableStateOf(null) } - ``` - (CharArray is NOT rememberSaveable-friendly by default; use a plain `remember { mutableStateOf(null) }` to avoid process-death leakage — losing the revealed state on config change is acceptable; user re-authenticates.) - - 5) When `revealed == null`, render the biometric cover card composable described in ``. When `revealed != null`, render the existing words grid bound to `revealed.joinToString(" ").split(" ")` or `String(revealed).split(" ")`. - - 6) On cover-card CTA tap, launch `LaunchedEffect` via `rememberCoroutineScope().launch { ... }`: - ```kotlin - val activity = context as? androidx.fragment.app.FragmentActivity - if (activity == null) { - snackbarHostState.showSnackbar("Biometric unavailable") - return@launch - } - val gate = io.raventag.app.security.BiometricGate(activity) - val result = io.raventag.app.security.MnemonicExporter.revealMnemonic(gate, wm) - result.onSuccess { chars -> revealed = chars } - result.onFailure { t -> - when (t) { - is io.raventag.app.security.BiometricCancelledException -> - snackbarHostState.showSnackbar(strings.authCanceledSnackbar) - is io.raventag.app.wallet.KeystoreInvalidatedException -> - onKeystoreInvalidated() - else -> snackbarHostState.showSnackbar(strings.mnemonicRevealFailed) - } - } - ``` - - 7) On screen dispose OR "Hide" toggle OR back nav: zero-fill `revealed`: - ```kotlin - DisposableEffect(revealed) { - onDispose { - revealed?.let { java.util.Arrays.fill(it, '\u0000') } - } - } - ``` - - 8) On "I've saved it" tap (existing button), BEFORE the existing nav-back call, set the backup flag: - ```kotlin - context.getSharedPreferences("raventag_wallet", android.content.Context.MODE_PRIVATE) - .edit().putBoolean("backup_completed", true).apply() - ``` - - 9) Add a new composable parameter `onKeystoreInvalidated: () -> Unit` to the screen signature. Update the single caller (WalletScreen or MainActivity — inspect at execution time) to pass a lambda that shows the Keystore-invalidated dialog and routes to restore. A minimal implementation: show a `oneTimeErrorDialogState = Error.KeystoreInvalidated` and let the calling screen render the dialog using `strings.deviceSecurityChangedTitle` / `Body` / `Cta`. - - 10) Ensure that FragmentActivity is the MainActivity base. If it isn't: - - Inspect `class MainActivity : ComponentActivity()` line. If it extends `ComponentActivity`, change to `androidx.fragment.app.FragmentActivity` (ComponentActivity is a subclass; the reverse is not true, but FragmentActivity extends ComponentActivity — verify). If MainActivity already extends AppCompatActivity or FragmentActivity, no change needed. - - Rationale: `androidx.biometric.BiometricPrompt(activity, ...)` requires `FragmentActivity`. - - Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt`. - - - cd android && ./gradlew :app:assembleConsumerDebug -q 2>&1 | tail -20 - - - - `grep -q "FLAG_SECURE" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "DisposableEffect" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "clearFlags" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "BiometricGate" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "MnemonicExporter.revealMnemonic" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "Arrays.fill" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "backup_completed" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "Icons.Default.Fingerprint" android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `grep -q "mnemonicBiometricCoverTitle" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Authenticate to reveal phrase" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Autenticati per mostrare la frase" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Reveal phrase" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Mostra frase" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "I've saved it" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "L'ho salvata" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Copy all" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Copia tutte" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Device security changed" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "La sicurezza del dispositivo è cambiata" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Authentication canceled" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `grep -q "Autenticazione annullata" android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` - - `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt` - - `cd android && ./gradlew :app:assembleConsumerDebug` exits 0. - - Biometric cover card and FLAG_SECURE live.

both one-shot RPC and the long-lived subscription socket route through it, NetworkModule has the single D-10 timeout pair, and AppConfig.ELECTRUM_SERVERS is the centralized pool. - -## What Was Built - -### Task 1: NodeHealthMonitor singleton + StateFlow (commit b0169a7) - -Created `android/app/src/main/java/io/raventag/app/wallet/health/NodeHealthMonitor.kt`: - -- `enum class ConnectionHealth { GREEN, YELLOW, RED }` (D-12 semantics). -- `object NodeHealthMonitor`: - - `init(context)` idempotent gate (double-checked synchronized lock). - - `nextHealthyNode()`: prunes recent failures by 30s cooldown + skips any host currently in `QuarantineDao.all()` with `quarantinedUntil > now`. - - `reportSuccess(host)` / `reportFailure(host, reason)` / `reportTofuMismatch(host)` update in-memory maps and recompute `_state`. - - `reportTofuMismatch` writes a 1h quarantine row via `QuarantineDao.quarantine(host, 3_600_000L, REASON_TOFU_MISMATCH)`. - - `stateFlow: StateFlow` (read-only) for plan 30-08 pill. - - `diagnostics()` returns per-host `NodeDiagnostic` list for plan 30-08 bottom sheet. - - `currentNode()` returns the most-recently-successful host. -- Recompute rule: - - quarantined == total → RED - - any failure within 30s + at least one fallback free → YELLOW - - any success within 60s → GREEN - - else (cold start / long idle) → YELLOW, promoting to GREEN on first success. - -Also added `val ELECTRUM_SERVERS: List>` with provenance KDoc to both `consumer` and `brand` `AppConfig` objects (flavor-scoped). The `main/` variant was removed to avoid duplicate-class errors. - -### Task 2: RPC + subscription paths routed through NodeHealthMonitor (commit f9067e6) - -`RavencoinPublicNode.kt`: - -- `callWithFailover(method, params)`: replaced the naive `for (server in SERVERS)` loop with a health-aware `repeat(SERVERS.size)` loop that calls `NodeHealthMonitor.nextHealthyNode()` before each attempt, reports success/failure to the monitor, classifies TOFU mismatches via a local `isTofuMismatch(e)` helper, and throws `AllNodesUnreachableException` when `nextHealthyNode()` returns null. -- `callWithFailoverBatch(requests)`: same treatment; returns `List(requests.size) { null }` on all-quarantined (preserves existing caller contract). -- `SERVERS` field now initialized from `AppConfig.ELECTRUM_SERVERS.map { (h, p) -> ElectrumServer(h, p) }` so there is one canonical pool. - -`SubscriptionManager.kt`: - -- `start(addresses)` consults `NodeHealthMonitor.nextHealthyNode()` per attempt, reports outcomes, and emits `ScripthashEvent.AllNodesDown` when all candidates fail. -- `readLoop` and `heartbeatLoop` now report failure (TOFU mismatch or named exception) to `NodeHealthMonitor` before emitting `ConnectionLost` / `PingTimeout`. -- Added `sessionKey(s)` to compute `"host:port"` form used as the monitor key. -- `DEFAULT_SERVERS` companion constant repointed to `AppConfig.ELECTRUM_SERVERS` so any legacy callers share the same pool. -- The existing 60s `pingIntervalMs` already covers D-10 zombie-socket detection (no new heartbeat added). - -`WalletExceptions.kt`: - -- Added `class AllNodesUnreachableException(msg: String = "all ElectrumX nodes quarantined") : RuntimeException(msg)`. - -### Task 3: NetworkModule timeout fix + MainActivity + worker init (commit 46623aa) - -`NetworkModule.kt`: - -- Removed the duplicate `connectTimeout(15, SECONDS)` / `readTimeout(30, SECONDS)` / `writeTimeout(30, SECONDS)` trio that shadowed the intended D-10 values. -- Canonical chain now has exactly one of each (verified: `grep -c 'connectTimeout' == 1`, `grep -c 'readTimeout' == 1`): `connectTimeout(10, SECONDS)`, `readTimeout(20, SECONDS)`, `writeTimeout(20, SECONDS)`. -- Before vs after: - - before: two pairs (lines 69-71 at 10/15/15s + duplicate at 82-84 at 15/30/30s) - - after: single pair at lines 71-73 matching D-10 (10/20/20s) - -`MainActivity.kt`: - -- Added `io.raventag.app.wallet.health.NodeHealthMonitor.init(this)` immediately after `WalletReliabilityDb.init(this)` + `ReservedUtxoDao.pruneOlderThan(...)` (block around line 2460). - -`WalletPollingWorker.kt` + `RebroadcastWorker.kt`: - -- First line of each `doWork()` now calls `NodeHealthMonitor.init(applicationContext)` defensively so a worker spawned before MainActivity has run still has `QuarantineDao` available. - -## Hand-off to Plan 30-08 (WalletScreen UI) - -- `NodeHealthMonitor.stateFlow: StateFlow` is the single StateFlow source for the D-12 connection pill (collect via `ViewModel.collectAsState()`). -- `NodeHealthMonitor.diagnostics()` feeds the "Fallback node list" in the tap-to-open bottom sheet. -- `NodeHealthMonitor.currentNode()` drives the "Current server" row in the bottom sheet. -- `AllNodesUnreachableException` is the thrown signal that plan 30-08 should catch to show the "Offline, all nodes unreachable" snackbar + disable Send/Receive. -- No Compose code was added in this plan (explicit scope boundary). - -## TOFU mismatch detection (identified at execution time) - -`TofuTrustManager.kt` throws a plain `Exception` with message `"Certificate mismatch for : expected , got "`. Both `RavencoinPublicNode` and `SubscriptionManager` classify this via: - -```kotlin -private fun isTofuMismatch(e: Throwable): Boolean { - if (e is java.security.cert.CertificateException) return true - val m = e.message ?: return false - return m.contains("Certificate mismatch", ignoreCase = true) || - m.contains("fingerprint mismatch", ignoreCase = true) || - m.contains("TOFU", ignoreCase = true) -} -``` - -The substring `"Certificate mismatch"` is the actual match in today's code; the other two are forward-compat for potential stack wrappings. - -## QuarantineDao API reconciliation - -Plan text assumed a `QuarantineDao.QuarantinedNode` data class with `upsert / activeAt / pruneExpired`. Reality (per plan 30-02 implementation in `wallet/health/QuarantineDao.kt`): -- `data class Quarantine(val host, val quarantinedUntil, val reason)` -- `fun quarantine(host, durationMillis, reason)` (inserts with `quarantined_until = now + durationMillis`) -- `fun isQuarantined(host)` / `fun clear(host)` / `fun all()` -- No explicit `pruneExpired` (rows age out naturally by the `quarantined_until > now` predicate). - -`NodeHealthMonitor.activeQuarantineHosts(now)` therefore calls `QuarantineDao.all().filter { it.quarantinedUntil > now }` in-memory. With a max of ~4 rows in the pool this is effectively free and matches the monitor's existing SQLite-lazy semantics. - -## Node list policy (RESEARCH Pitfall 8) - -All 4 original hosts retained (`rvn4lyfe.com`, `rvn-dashboard.com`, `162.19.153.65`, `51.222.139.25`). Provenance KDoc added to both flavor `AppConfig` files. `rvn-dashboard.com` is kept despite RESEARCH flagging it LOW confidence: quarantine handles staleness silently without user impact. - -## Flavor considerations - -Because `AppConfig` is a flavor-scoped object (separate files in `src/consumer/` and `src/brand/`), `ELECTRUM_SERVERS` was added to BOTH. Build verified against `:app:assembleConsumerDebug`; the brand variant will pick up the symmetric definition on its next build. - -## Deviations from Plan - -### Auto-fixed Issues - -**1. [Rule 3 - Blocker] AppConfig package did not exist in `main/`** -- **Found during:** Task 1 -- **Issue:** Plan assumed `io.raventag.app.config.AppConfig` was a single `main/` source; actual project has per-flavor AppConfig files in `src/consumer/` and `src/brand/` with different booleans per flavor. Adding a `main/` version caused a duplicate-class build failure. -- **Fix:** Removed `main/` variant, extended both flavor AppConfig files with the same `ELECTRUM_SERVERS` constant. -- **Commit:** b0169a7 - -**2. [Rule 3 - Blocker] QuarantineDao real API differs from plan interfaces** -- **Found during:** Task 1 -- **Issue:** Plan assumed `QuarantinedNode / upsert / activeAt / pruneExpired`; actual API is `Quarantine / quarantine / all / isQuarantined / clear`. -- **Fix:** NodeHealthMonitor filters `QuarantineDao.all()` by `quarantinedUntil > now` in-memory; calls `QuarantineDao.quarantine(host, 3_600_000L, REASON_TOFU_MISMATCH)` for 1h quarantine. No behavior change vs plan intent. -- **Commit:** b0169a7 - -**3. [Rule 2 - Correctness] Workers missing NodeHealthMonitor.init** -- **Found during:** Task 3 -- **Issue:** Plan flagged this as a defensive need; confirmed neither worker had any DAO init at doWork entry, risking NPE on cold-start. -- **Fix:** Added `NodeHealthMonitor.init(applicationContext)` as first line of both `WalletPollingWorker.doWork()` and `RebroadcastWorker.doWork()`. -- **Commit:** 46623aa - -## Deferred Issues - -- **Pre-existing em dashes in RavencoinPublicNode.kt** (lines 283, 287, 329 before edits).

On TLS / TOFU mismatch exception (detected via `e is javax.net.ssl.SSLException && e.message?.contains("Certificate") == true`, OR `e is java.security.cert.CertificateException`, OR the project's specific TOFU mismatch exception class — inspect TofuTrustManager.kt to confirm the class): `NodeHealthMonitor.reportTofuMismatch(candidate)`; continue to next iteration. - 6.

If all fail, throw the last exception (or `AllNodesUnreachableException`). - - - Preserve existing behavior when `NodeHealthMonitor` has not been `init()`ed yet (defensive — `nextHealthyNode()` returns the first server when `QuarantineDao` is uninitialized? Per plan 30-02, `QuarantineDao.init` is called from `MainActivity.onCreate`.

Try to open session to that host; subscribe; launch reader loop. - c. On success: `NodeHealthMonitor.reportSuccess(host)`; break out of the retry loop. - d.

On any other failure: `NodeHealthMonitor.reportFailure(host, e.javaClass.simpleName)`; loop. - - In the reader loop coroutine, wrap `reader.readLine()` failures with a TOFU / network-error check and call the corresponding `NodeHealthMonitor.report*` method before emitting `ScripthashEvent.ConnectionLost`. - - In the 60s heartbeat (Pitfall 2 — introduced by plan 30-03), on ping failure call `NodeHealthMonitor.reportFailure(host, "ping_timeout")` then attempt reconnect via the regular `start()` path. - - - **WalletExceptions.kt** — add: - ```kotlin - class AllNodesUnreachableException(msg: String = "all ElectrumX nodes quarantined") : RuntimeException(msg) - ``` - - **RavencoinPublicNode.kt** — locate `callWithFailover` (the method wrapping `call()` per-server iteration — identify via grep at execution time; the existing signature is `internal fun callWithFailover(method: String, params: List): com.google.gson.JsonElement`).

This plan closes every visible D-01/02/04/06/07/08/12/18/24/26/28 decision. -Output: in-place extensions to WalletScreen.kt, ReceiveScreen.kt, WalletPollingWorker.kt, MainActivity.kt; one new NotificationHelper file; EN + IT string additions verbatim from UI-SPEC Copywriting Contract. - -Hard constraints: -- Do NOT touch `RavencoinTxBuilder.kt` (D-17). -- Do NOT redesign the Phase 20 `transaction_progress` channel; the `incoming_tx` channel is strictly additive. -- All new user-visible strings must be added to `AppStrings.kt` `stringsEn` + `stringsIt` in English AND Italian per UI-SPEC Copywriting Contract. -- No U+2014 em-dashes anywhere in touched files. -- Connection pill visual rendering lives HERE; the data source (StateFlow) was produced by plan 30-07. -- Scripthash subscription lifecycle (start/stop per foreground) lives HERE; the wire protocol and Flow API were produced by plan 30-03. - - - -@$HOME/.claude/get-shit-done/workflows/execute-plan.md -@$HOME/.claude/get-shit-done/templates/summary.md - - - -@.planning/phases/30-wallet-reliability/30-CONTEXT.md -@.planning/phases/30-wallet-reliability/30-RESEARCH.md -@.planning/phases/30-wallet-reliability/30-PATTERNS.md -@.planning/phases/30-wallet-reliability/30-UI-SPEC.md -@.planning/phases/30-wallet-reliability/30-VALIDATION.md -@.planning/phases/30-wallet-reliability/30-02-wallet-cache-db-daos-PLAN.md -@.planning/phases/30-wallet-reliability/30-03-scripthash-subscription-PLAN.md -@.planning/phases/30-wallet-reliability/30-05-consolidation-reliability-PLAN.md -@.planning/phases/30-wallet-reliability/30-07-node-reliability-PLAN.md -@android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt -@android/app/src/main/java/io/raventag/app/ui/screens/ReceiveScreen.kt -@android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt -@android/app/src/main/java/io/raventag/app/worker/NotificationHelper.kt -@android/app/src/main/java/io/raventag/app/worker/TransactionNotificationHelper.kt -@android/app/src/main/java/io/raventag/app/MainActivity.kt -@android/app/src/main/java/io/raventag/app/ui/theme/AppStrings.kt -@android/app/src/main/java/io/raventag/app/ui/theme/Theme.kt -@android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt -@android/app/src/consumer/java/io/raventag/app/config/AppConfig.kt - - -**Types and singletons produced by upstream plans (consumed here — DO NOT redeclare):** - -```kotlin -// From plan 30-02 (wallet/cache) -object WalletCacheDao { - data class CachedWalletState( - val walletId: String, - val balanceSat: Long, - val utxos: List, - val assetUtxos: Map>, - val blockHeight: Int, - val lastRefreshedAt: Long - ) - fun init(context: android.content.Context) - fun writeState(utxos: List, assetUtxos: Map>, blockHeight: Int) - fun readState(): CachedWalletState? - fun getLastRefreshedAt(): Long -} - -// From plan 30-03 (wallet/subscription) -sealed class ScripthashEvent { - data class StatusChanged(val scripthash: String, val newStatus: String?) : ScripthashEvent() - data object ConnectionLost : ScripthashEvent() - data object AllNodesDown : ScripthashEvent() -} -class SubscriptionManager(private val context: android.content.Context) { - suspend fun start(addresses: List) - suspend fun stop() - fun eventsFlow(): kotlinx.coroutines.flow.SharedFlow -} - -// RavencoinPublicNode extension from plan 30-03 (one-shot scripthash status fetch for WorkManager path) -// NOTE: confirm exact signature at execution time against plan 30-03 source; fall back to a thin -// wrapper around callWithFailover("blockchain.scripthash.subscribe", listOf(scripthash)) that -// returns the String status hash if the named wrapper is missing. -fun io.raventag.app.wallet.RavencoinPublicNode.subscribeScripthashRpc(address: String): String? - -// From plan 30-07 (wallet/health + wallet) -enum class ConnectionHealth { GREEN, YELLOW, RED } -object NodeHealthMonitor { - fun init(context: android.content.Context) - fun nextHealthyNode(): String? - fun reportSuccess(host: String) - fun reportFailure(host: String, reason: String) - fun reportTofuMismatch(host: String) - val stateFlow: kotlinx.coroutines.flow.StateFlow - data class NodeDiagnostic( - val host: String, - val lastSuccessAt: Long?, - val lastFailureAt: Long?, - val lastError: String?, - val quarantinedUntil: Long? - ) - fun diagnostics(): List - fun currentNode(): String? -} -class AllNodesUnreachableException(msg: String = "all ElectrumX nodes quarantined") : RuntimeException(msg) -``` - -**New types introduced by THIS plan (consumed by plan 30-10 and the housekeeping audit):** - -```kotlin -// android/app/src/main/java/io/raventag/app/worker/IncomingTxNotificationHelper.kt -object IncomingTxNotificationHelper { - const val CHANNEL_ID: String = "incoming_tx" - const val ACTION_VIEW_TRANSACTION: String = "VIEW_TRANSACTION" - const val EXTRA_TXID: String = "txid" - fun createChannel(context: android.content.Context) - /** - * Builds a notification for an incoming transaction.

In `MainActivity.onCreate`, immediately after the existing `NotificationHelper.createChannel(this)` and `TransactionNotificationHelper.createChannel(this)` calls (MainActivity.kt ~ lines 2447-2451 per PATTERNS.md line 447), add: - ```kotlin - io.raventag.app.worker.IncomingTxNotificationHelper.createChannel(this) - ``` - If plan 30-07 already inserted `NodeHealthMonitor.init(this)` after the channel creations, place the `createChannel` call BEFORE `NodeHealthMonitor.init(this)` so all three channels are registered before any worker or monitor fires. - - 2. Add a private helper method `private fun handleIncomingTxIntent(intent: Intent?)`: - - Checks `intent?.action == IncomingTxNotificationHelper.ACTION_VIEW_TRANSACTION` (reuses the constant; `TransactionNotificationHelper.ACTION_VIEW_TRANSACTION_EXT` also has the same string value `"VIEW_TRANSACTION"` — either constant works, prefer the IncomingTx one to avoid coupling to Phase 20 helper). - - If true, reads `val txid = intent.getStringExtra(IncomingTxNotificationHelper.EXTRA_TXID)`. - - If `txid != null`, calls the existing navigation lambda that opens TransactionDetailsScreen (inspect MainActivity for the current navigation state — likely a `mutableStateOf` or a `navController.navigate("tx/$txid")` pattern; the executor MUST identify and reuse that exact path). - - 3. Invoke `handleIncomingTxIntent(intent)` in: - - `onCreate(savedInstanceState: Bundle?)` — after `super.onCreate` and after `setContent { ... }` is composed (use a `LaunchedEffect(Unit)` inside setContent OR call `handleIncomingTxIntent(intent)` AFTER setContent since the navigation state is set up at that point — defer to the existing navigation pattern). - - `override fun onNewIntent(intent: Intent)` — if this override does not yet exist, add it. Call `super.onNewIntent(intent)` then `setIntent(intent)` then `handleIncomingTxIntent(intent)`. - - 4. If MainActivity already handles `TransactionNotificationHelper`'s `VIEW_TRANSACTION` action (it does, per the existing TransactionNotificationHelper deep-link pattern), the SAME handler can route both sources since the action string and extra key are identical. In that case, ensure the handler distinguishes ONLY by the presence of the `txid` extra (incoming path) vs the Phase 20 confirmed-send path (which also uses `txid`). Route both to TransactionDetailsScreen — no behavioral divergence needed. - - Em-dash audit on the touched lines (inspect diff). - - - 1) Locate the block in MainActivity.kt around lines 2447-2461 (per PATTERNS.md line 447) that contains: - ```kotlin - io.raventag.app.worker.NotificationHelper.createChannel(this) - io.raventag.app.worker.TransactionNotificationHelper.createChannel(this) - ``` - - 2) Insert a new line immediately after those two: - ```kotlin - io.raventag.app.worker.IncomingTxNotificationHelper.createChannel(this) - ``` - - 3) Inspect the existing code for any `ACTION_VIEW_TRANSACTION` handler (search for `TransactionNotificationHelper.ACTION_VIEW_TRANSACTION_EXT` OR for a literal `"VIEW_TRANSACTION"` string — MainActivity.kt already contains the Phase 20 deep-link per TransactionNotificationHelper.kt:34). If a handler exists, verify it already reads `EXTRA_TXID`/`"txid"` and routes to TransactionDetailsScreen; then no further change is required (the new IncomingTxNotificationHelper reuses the same action + extra). - - 4) If NO handler exists yet (i.e., Phase 20 plan 20-05 is unchecked on ROADMAP so the deep-link was never wired), add one: - ```kotlin - private fun handleIncomingTxIntent(intent: Intent?) { - if (intent?.action == io.raventag.app.worker.IncomingTxNotificationHelper.ACTION_VIEW_TRANSACTION) { - val txid = intent.getStringExtra(io.raventag.app.worker.IncomingTxNotificationHelper.EXTRA_TXID) - if (!txid.isNullOrBlank()) { - // Route to TransactionDetailsScreen. Use the existing nav state variable - // that WalletScreen uses for the "view tx details" tap. SUMMARY must - // record the exact navigation hook used. - pendingTxNavigation.value = txid - } - } - } - ``` - ...where `pendingTxNavigation` is a `MutableState` declared at class scope (or a reusable existing one). The `setContent { }` block reads this state inside a `LaunchedEffect(pendingTxNavigation.value)` and calls the existing tx-detail navigation hook. - - Then: - ```kotlin - override fun onNewIntent(intent: Intent) { - super.onNewIntent(intent) - setIntent(intent) - handleIncomingTxIntent(intent) - } - ``` - - And call `handleIncomingTxIntent(intent)` at the end of `onCreate` (after `setContent`). - - 5) DO NOT disturb the existing `TransactionNotificationHelper` deep-link (Phase 20 D-04) if already wired; the new helper is strictly additive via the shared action string. - - Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/MainActivity.kt` on the full file. If the file already contains em dashes from prior code, the executor MUST replace them with `:`, `,`, or `·` during this pass (this is a hard project rule — see MEMORY). - - Record in SUMMARY.md: (a) the exact method name + line number where `IncomingTxNotificationHelper.createChannel(this)` was inserted; (b) whether a VIEW_TRANSACTION handler already existed or a new one was added; (c) the navigation hook the handler calls (e.g., `navController.navigate("tx_details/$txid")` or `selectedScreen.value = Screen.TxDetails(txid)`). - - - cd android && ./gradlew :app:assembleConsumerDebug -q 2>&1 | tail -30 - - - - `grep -q "IncomingTxNotificationHelper.createChannel(this)" android/app/src/main/java/io/raventag/app/MainActivity.kt` - - `grep -q "IncomingTxNotificationHelper.ACTION_VIEW_TRANSACTION\|ACTION_VIEW_TRANSACTION_EXT\|\"VIEW_TRANSACTION\"" android/app/src/main/java/io/raventag/app/MainActivity.kt` - - `grep -q "IncomingTxNotificationHelper.EXTRA_TXID\|EXTRA_TXID_EXT\|getStringExtra(\"txid\")" android/app/src/main/java/io/raventag/app/MainActivity.kt` - - Either `grep -q "override fun onNewIntent" android/app/src/main/java/io/raventag/app/MainActivity.kt` is true OR the existing `onCreate` already calls a VIEW_TRANSACTION handler. - - `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/MainActivity.kt` - - `cd android && ./gradlew :app:assembleConsumerDebug` exits 0. - - incoming_tx channel registered at startup.

The new pass: - - 1. Reads the wallet's current receive address list (at minimum: the current `currentIndex` address used by ReceiveScreen; optionally the last N addresses — v1 keeps it single-address to match the quantum-resistance model where only `currentIndex` is ever the active receive). The worker already has the necessary WalletManager access per the existing pattern; reuse it. - - 2. For each address `addr`: - a. Compute scripthash via the existing `io.raventag.app.wallet.RavencoinPublicNode.addressToScripthash(addr)` helper (or equivalent already used in the worker). - b. Issue a ONE-SHOT RPC call to `blockchain.scripthash.subscribe` (this is functionally a "get current status" call in ElectrumX — the subscription aspect requires a persistent socket which is plan 30-03's domain; the RPC returns the status hash immediately). Call signature: `node.subscribeScripthashRpc(addr)` if plan 30-03 exported that wrapper, else a direct `node.callWithFailover("blockchain.scripthash.subscribe", listOf(scripthash))` followed by `?.takeUnless { it.isJsonNull }?.asString`. - c. Fetch SharedPreferences: `val prevStatus = prefs.getString("last_status_$addr", null)` (file `"wallet_poll"`, same file used by Phase 20 `poll_rvn_sat`). - d. If `currentStatus != prevStatus`: - - Persist new status: `prefs.edit().putString("last_status_$addr", currentStatus).apply()`. - - Re-fetch balance via the existing `RavencoinPublicNode.getBalance(addr)` path. - - Compute delta vs the previously-cached balance (`poll_rvn_sat` key, existing). - - If delta > 0 (new incoming funds): find the newest transaction in `node.getTransactionHistory(addr, limit = 3, offset = 0)` that is NOT already in SharedPreferences key `"last_notified_txid"`; call `IncomingTxNotificationHelper.showIncoming(applicationContext, newTxid, rvnAmount = deltaSat / 1e8, confirmations = newTxEntry.confirmations)`. Save the new `last_notified_txid`. - - On first run (prevStatus == null): do NOT notify — persist the current status and balance; subsequent runs compare against these baselines. Rationale: avoid spamming the user on fresh install with a retroactive "incoming" for any existing balance. - - 3. Resilience policy mirrors the existing worker (WalletPollingWorker.kt:116-122): - - `java.io.IOException` → `Result.retry()`. - - Any other `Exception` → swallow gracefully, `Result.success()`. - - Do NOT surface errors to the user (D-06 is a silent background path). - - 4. Call `NodeHealthMonitor.init(applicationContext)` at the top of `doWork()` (plan 30-07 hand-off). The node health monitor is a singleton and the call is idempotent. - - SharedPreferences keys in use (same file `"wallet_poll"`): - - `poll_rvn_sat` — Long, existing Phase 20 last-seen balance. - - `last_status_` — String, new, per-address scripthash status. - - `last_notified_txid` — String, new, the most recent txid a D-06 notification fired for. - - Em-dash audit on file. - - - 1) Read the full `WalletPollingWorker.kt` file to identify the WalletManager + RavencoinPublicNode access pattern already in place. - - 2) At the TOP of `doWork()` inside the `withContext(Dispatchers.IO)` block, add (if not already present after plan 30-07): - ```kotlin - io.raventag.app.wallet.health.NodeHealthMonitor.init(applicationContext) - ``` - - 3) AFTER the existing balance-diff notification logic (look for the current `NotificationHelper.notify(...)` call), add a new block: - ```kotlin - try { - val addresses = buildList { - // Use whatever receive-address resolver the worker currently uses. - // At minimum the current index address.

If the worker constructs a new one per run (`val wm = WalletManager(applicationContext)`), keep that pattern. - - `prefs` — already exists per `PATTERNS.md` line 236 (`applicationContext.getSharedPreferences("wallet_poll", MODE_PRIVATE)`). - - `wm.getCurrentReceiveAddress()` — the method may be named differently in the existing code (e.g., `getCurrentAddress()`, `getReceiveAddress(currentIndex)`, or computed from `currentIndex`). Inspect at execution time and use the exact existing accessor; SUMMARY.md records the precise name. - - 4) Ensure the new block executes AFTER the existing Phase 20 balance-diff logic (so that the `poll_rvn_sat` key is already read and any existing notification is already dispatched before the new scripthash-diff pass). - - Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt`. - - - cd android && ./gradlew :app:compileConsumerDebugKotlin -q 2>&1 | tail -20 - - - - `grep -q "blockchain.scripthash.subscribe" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `grep -q "last_status_" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `grep -q "last_notified_txid" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `grep -q "IncomingTxNotificationHelper.showIncoming" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `grep -q "NodeHealthMonitor.init(applicationContext)" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `grep -q "Result.retry()" android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` - - `cd android && ./gradlew :app:compileConsumerDebugKotlin` exits 0. - - WorkManager worker now performs per-address scripthash-status diff, fires IncomingTxNotificationHelper on positive balance delta post-baseline, preserves Phase 20 balance-diff logic, silent on any error except IOException which retries.

Any "HH:MM" value gets formatted by the caller (e.g., `String.format(strings.cachedStateBanner, "14:32")`). - - The `%1$s` RVN amount in `incomingTxSnackbar` is passed as the pre-formatted RVN string (e.g., `String.format("%.8f", rvnDouble)` produced by the caller). - - Em-dash audit mandatory. - - - 1) Read `AppStrings.kt` fully. Identify the shape: - - A `class AppStrings` declaring public properties (likely all `var x: String = "..."`). - - A `val stringsEn: AppStrings = AppStrings().apply { ... }` instance near ~line 393 per PATTERNS. - - A `val stringsIt: AppStrings = AppStrings().apply { ... }` instance near ~line 608. - - A `val LocalStrings = staticCompositionLocalOf { stringsEn }` provider at the bottom (or similar). - - 2) Declare the new `var` properties on `class AppStrings` with EN defaults: - ```kotlin - var cachedStateBanner: String = "Showing cached state \u00B7 Last updated %1\$s" - var cachedStateReconnecting: String = "Last updated %1\$s \u00B7 reconnecting\u2026" - var pendingBalanceLabel: String = "Pending" - var batterySaverChip: String = "Battery saver \u00B7 manual refresh" - var connectionPillOnline: String = "Online" - var connectionPillReconnecting: String = "Reconnecting\u2026" - var connectionPillOffline: String = "Offline" - var connectionPillSheetTitle: String = "Ravencoin network" - var connectionPillCurrentNode: String = "Current node" - var connectionPillLastSuccess: String = "Last successful RPC" - var connectionPillFallbackNodes: String = "Fallback nodes" - var connectionPillQuarantined: String = "Quarantined until %1\$s" - var connectionPillClose: String = "Close" - var reconnectingToast: String = "Reconnecting to Ravencoin network\u2026" - var offlineAllNodesUnreachable: String = "Offline \u00B7 all nodes unreachable" - var incomingTxSnackbar: String = "+%1\$s RVN received" - var receiveCurrentAddressLabel: String = "Your current address" - var receiveCurrentAddressSubLabel: String = "Changes after your next send or consolidation." - var walletOfflineHeading: String = "Wallet offline" - var walletOfflineBody: String = "Cannot reach any Ravencoin node.

The screen's existing architecture uses a `WalletInfo` data class (line ~62-68) and `electrumStatus: MainViewModel.ElectrumStatus` parameter (line ~90) — preserve existing parameters; add what is needed. - - Sub-elements to add (each is its own private composable where reasonable): - - 5.1) `@Composable private fun CachedStateBanner(lastRefreshedAt: Long?, isReconnecting: Boolean, visible: Boolean)`: - - Visible iff `visible == true` AND `lastRefreshedAt != null`. - - Card: `RavenCard` bg, `1.dp RavenBorder` border, `RoundedCornerShape(12.dp)`, padding `12dp`. - - Row: `Icons.Default.History` 16dp `RavenMuted` + 8dp gap + Text bodySmall RavenMuted. - - Text value: - - when `isReconnecting == false`: `String.format(strings.cachedStateBanner, formatHhMm(lastRefreshedAt))` → EN "Showing cached state · Last updated HH:MM" / IT "Stato in cache · Ultimo aggiornamento HH:MM". - - when `isReconnecting == true`: `String.format(strings.cachedStateReconnecting, formatHhMm(lastRefreshedAt))` → EN "Last updated HH:MM · reconnecting…" / IT "Ultimo aggiornamento HH:MM · riconnessione…". - - `formatHhMm(ms)` → `java.text.SimpleDateFormat("HH:mm", Locale.getDefault()).format(java.util.Date(ms))`. - - Auto-dismiss: caller sets `visible = false` as soon as a successful refresh completes. - - 5.2) `@Composable private fun PendingBalanceLine(mempoolIncomingSat: Long)`: - - Hidden entirely when `mempoolIncomingSat <= 0L`. - - Row: `Icons.Default.Schedule` 12dp RavenMuted + 4dp gap + Text "Pending"/"In attesa" (`strings.pendingBalanceLabel`) bodySmall RavenMuted + 8dp gap + Text amount formatted `"+%.8f RVN"`. - - Amount color: `Color(0xFFF59E0B)` (amber literal, per UI-SPEC §Pending balance line). Use `Color(0xFFF59E0B)` inline (not from Theme — the amber is a Phase 30 addition that UI-SPEC keeps literal). - - Style: `bodySmall` / Normal weight. - - 5.3) `@Composable private fun BatterySaverChip()`: - - Only rendered when `PowerManager.isPowerSaveMode() == true`. Caller gates rendering; chip itself is unconditional once rendered. - - Card container: `RavenCard` bg, `RoundedCornerShape(8.dp)`, `BorderStroke(1.dp, Color(0xFFF59E0B).copy(alpha = 0.25f))`. - - Inner padding: `horizontal = 8.dp, vertical = 4.dp`. - - Content: Row — `Icons.Default.BatterySaver` 10dp amber `Color(0xFFF59E0B)` + 4dp gap + Text `strings.batterySaverChip` labelSmall amber. - - Tap: does nothing (informational). No clickable modifier. - - 5.4) Extend the existing `ElectrumStatusBadge` (WalletScreen.kt:757-780) with a YELLOW state: - - Drive pill color from `NodeHealthMonitor.stateFlow.collectAsState(initial = ConnectionHealth.GREEN)` — the screen already has a binding; pass the enum in. - - GREEN: existing behavior — AuthenticGreen dot pulsing + text `strings.connectionPillOnline`. - - YELLOW: amber `Color(0xFFF59E0B)` pulsing dot + text `strings.connectionPillReconnecting`. - - RED: NotAuthenticRed STATIC dot (no pulse) + text `strings.connectionPillOffline`. - - Dot pulse animation: reuse the existing animation modifier the badge already has for GREEN; apply to YELLOW; suppress on RED. - - The pill itself must be tappable: `Modifier.clickable { showConnectionSheet = true }`. Accessibility touch target ≥ 48dp (use `Modifier.sizeIn(minHeight = 48.dp)` or equivalent). - - 5.5) Connection pill tap sheet: `@Composable private fun ConnectionPillSheet(onDismiss: () -> Unit)`: - - `ModalBottomSheet(onDismissRequest = onDismiss, containerColor = RavenCard)` from `androidx.compose.material3`. - - Content column, padding 16dp: - - Title bar: Text `strings.connectionPillSheetTitle` titleSmall SemiBold white. - - Section 1: Text `strings.connectionPillCurrentNode` labelSmall RavenMuted + Text `NodeHealthMonitor.currentNode() ?: "—"` bodySmall monospace white. (Note: the dash `—` literal is forbidden per MEMORY. Replace with the explicit fallback string `"(none)"` / `"(nessuno)"` — add a new property `connectionPillNoNode` to AppStrings if needed in Task 4 above; if not already added, executor adds inline literals `"(none)"`/`"(nessuno)"` here and appends the missing string to AppStrings in the same diff.) - - Section 2: Text `strings.connectionPillLastSuccess` labelSmall RavenMuted + Text formatted timestamp from `NodeHealthMonitor.diagnostics()` for `currentNode()`; format via `formatHhMm(...)` or `"—"` equivalent non-emdash fallback. - - Section 3: Text `strings.connectionPillFallbackNodes` labelSmall RavenMuted, then a Column over `NodeHealthMonitor.diagnostics()`. Each row: status circle (green if `quarantinedUntil == null`, red if quarantined) + 8dp gap + host string (monospace bodySmall) + if quarantined: 8dp + Text formatted via `strings.connectionPillQuarantined` with HH:MM. - - Close button at bottom: `OutlinedButton(onClick = onDismiss, border = BorderStroke(1.dp, RavenBorder))` with Text `strings.connectionPillClose`. - - 5.6) Sync-in-background indicator: a 2dp `LinearProgressIndicator` placed flush below the wallet header. Visible while `isRefreshing == true`. Colors: `LinearProgressIndicator(color = RavenOrange, trackColor = RavenBorder)`. `height = 2.dp`. Indeterminate. - - 5.7) Disabled Send/Receive when pill is RED: - - Read `val health by NodeHealthMonitor.stateFlow.collectAsState(initial = ConnectionHealth.GREEN)`. - - When `health == ConnectionHealth.RED`: - - Send button: `Modifier.alpha(0.3f)`, text color `RavenMuted`, icon tint `RavenMuted`, `enabled = false` (so the existing onClick does not fire). - - Receive button: same as Send. - - Wrap the button Row with `Modifier.clickable(enabled = true)` that shows a Snackbar using `strings.offlineAllNodesUnreachable` on `NotAuthenticRedBg` container. The clickable MUST be attached to the wrapper, NOT the disabled button, so that even when `enabled = false`, the tap still fires the snackbar. Use `LaunchedEffect` with a `MutableState` that triggers `snackbarHostState.showSnackbar(...)`. - - When `health != ConnectionHealth.RED`: existing Send/Receive behavior unchanged. - - 5.8) 30-second periodic refresh loop, gated by power-save: - - In the WalletScreen `@Composable`, add: - ```kotlin - val context = LocalContext.current - val lifecycleState = ... // existing lifecycle observer pattern - LaunchedEffect(lifecycleState) { - while (true) { - kotlinx.coroutines.delay(30_000L) - val pm = context.getSystemService(android.content.Context.POWER_SERVICE) as android.os.PowerManager - if (!pm.isPowerSaveMode) { - onPeriodicRefresh() // existing refresh hook - } - } - } - ``` - - The scripthash subscription (plan 30-03 SubscriptionManager) stays alive regardless of power-save — its own lifecycle is managed independently by the WalletViewModel / SubscriptionManager start()/stop() paired with foreground state (already wired by plan 30-03). - - 5.9) In-app Snackbar on incoming tx: - - Collect `SubscriptionManager.eventsFlow()` (inject via existing DI or `remember { SubscriptionManager(context) }` used elsewhere in the file). - - On each `ScripthashEvent.StatusChanged`: schedule a re-fetch via the existing refresh hook. AFTER the re-fetch completes, compute `deltaSat = newBalance - previousBalance`. If `deltaSat > 0L`: - - `snackbarHostState.showSnackbar(String.format(strings.incomingTxSnackbar, String.format("%.8f", deltaSat / 1e8)))`. - - Visual: this task keeps the snackbar call; the styled Snackbar host that paints AuthenticGreenBg + AuthenticGreen text + Icons.Default.CallReceived is the screen's top-level `SnackbarHost` configuration. If the existing SnackbarHost does not support per-call theming, add a `customSnackbar` override using `Snackbar(containerColor = AuthenticGreenBg, contentColor = AuthenticGreen, action = null)` with an icon-decorated message body. - - 5.10) Instant-render cached state on open: - - On first composition (`LaunchedEffect(Unit)`): read `WalletCacheDao.readState()` and seed the screen state (balance, tx list) BEFORE any network call. Track `lastRefreshedAt = WalletCacheDao.getLastRefreshedAt()`. Flip `showCachedBanner = true` while a successful refresh has not yet completed. - - Order of composition additions on the screen header column (top-down): - 1. Existing `walletTitle` Text row. - 2. Row: block height + ElectrumStatusBadge (YELLOW-capable) + Refresh icon. - 3. `BatterySaverChip()` (conditional). - 4. `CachedStateBanner(...)` (conditional). - 5. 2dp LinearProgressIndicator (conditional on `isRefreshing`). - 6. BalanceCard (existing, with PendingBalanceLine inserted inside directly under fiat). - 7. Actions Row (Send / Receive with disabled-state wrapper). - 8. Existing LazyColumn tx history (untouched in this task; plan 30-09 rewrites the outgoing row). - - Em-dash audit on WalletScreen.kt. - - - 1) Read `WalletScreen.kt` fully. Identify the exact names of: - - The existing `electrumStatus`/`ElectrumStatus` parameter or ViewModel field. - - The existing refresh hook (`onRefresh`, `viewModel.refresh()`, or inline fetch block). - - The existing `LazyColumn`/`BalanceCard`/`ActionsRow` composables. - - The existing `SnackbarHost` / `SnackbarHostState` binding. - - 2) Add `import`s as needed: - ```kotlin - import androidx.compose.material.icons.filled.History - import androidx.compose.material.icons.filled.Schedule - import androidx.compose.material.icons.filled.BatterySaver - import androidx.compose.material.icons.filled.CallReceived - import androidx.compose.material3.LinearProgressIndicator - import androidx.compose.material3.ModalBottomSheet - import androidx.compose.material3.rememberModalBottomSheetState - import androidx.compose.runtime.collectAsState - import io.raventag.app.wallet.health.NodeHealthMonitor - import io.raventag.app.wallet.health.ConnectionHealth - import io.raventag.app.wallet.cache.WalletCacheDao - import io.raventag.app.wallet.subscription.SubscriptionManager - import io.raventag.app.wallet.subscription.ScripthashEvent - ``` - - 3) Add the five private composables above (`CachedStateBanner`, `PendingBalanceLine`, `BatterySaverChip`, extension to `ElectrumStatusBadge`, `ConnectionPillSheet`) inside WalletScreen.kt, ideally at the bottom of the file next to the existing pattern. - - 4) Insert usages in the top-level `WalletScreen` composable in the stated order. - - 5) Wire the 30-second `LaunchedEffect` loop with `isPowerSaveMode` gate.

No balance value comes from the push payload. | -| WorkManager one-shot scripthash RPC → notification | The RPC call is pinned via the same TofuTrustManager; notification payload is derived only from a successful `getBalance` + `getTransactionHistory` result. | -| NotificationChannel `incoming_tx` → system | Only this app's process writes to the channel (Android enforces this). Cross-app notification spoofing is not applicable. | -| Intent `VIEW_TRANSACTION` + `txid` extra → MainActivity | Intent originates from this app's own PendingIntent with FLAG_IMMUTABLE; external intents without the correct package/component cannot forge. | - -## STRIDE Threat Register - -| Threat ID | Category | Component | Disposition | Mitigation Plan | -|-----------|----------|-----------|-------------|-----------------| -| T-30-RECV-04 | Spoofing | Malicious ElectrumX server pushes forged `scripthash.subscribe` notification to mislead WalletScreen | mitigate | Notification only triggers a re-fetch via `RavencoinPublicNode` (TofuTrustManager + TLS). Balance written from RPC result, never from notification payload (RESEARCH §Pattern 1 invariants). | -| T-30-RECV-05 | Tampering | Stale scripthash status in SharedPreferences causes missed incoming notification after process death | accept | Baseline-on-first-run is intentional (no retroactive spam). Subsequent runs compare against persisted state. Worst case: one missed notification for a tx that arrived in the brief baseline window — the tx still appears in history on next WalletScreen open. | -| T-30-RECV-06 | Tampering | Notification payload uses server-reported confirmations; malicious server could mislead variant selection (mempool vs confirmed) | accept | Impact limited to text style; balance delta is derived from the Keystore-protected local cache vs fresh RPC, so even a spoofed "6 confirms" cannot change the amount the user sees. User still verifies on WalletScreen. | -| T-30-NET-08 | Denial of Service | Attacker forces a rapid scripthash-status flap to spam notifications | mitigate | WalletPollingWorker runs at 15-min intervals (OS-enforced minimum). Foreground subscription collapses bursts via SharedFlow `extraBufferCapacity` (plan 30-03). Snackbar for incoming is transient (SnackbarDuration.Short). | -| T-30-NET-09 | Information Disclosure | PendingIntent leaks txid to other apps | accept | PendingIntent uses `FLAG_IMMUTABLE` + explicit component targeting MainActivity. txid is public blockchain data; no secret disclosed. | -| T-30-NET-10 | Elevation of Privilege | Malicious external intent replays `VIEW_TRANSACTION` with arbitrary `txid` | accept | TransactionDetailsScreen fetches details via trusted RPC; displaying a forged txid only shows "tx not found" — no privileged action is taken.

The consolidation-centric quantum-resistance model (D-17) is now legible to the user: outgoing transactions clearly separate what left the wallet (Sent, red) from what cycled to a fresh change address (Cycled, green) from the miner fee (Fee, muted). Self-transfers collapse to a single Cycled + Fee line with an Autorenew icon, so pure consolidations are visually distinct from external sends. Incoming rows are preserved exactly as before. - -## What Changed - -### Task 1: RavencoinPublicNode additions (commit 09ae52c) -- `suspend fun getHistoryPaged(address, offset, limit = 20)` wraps `blockchain.scripthash.get_history` with client-side slicing, reuses batch call pattern for tip height + history, returns `emptyList()` on failure (Load more resilient). -- `object RavencoinTxHistoryMath` with pure `computeCycledSat(tx, changeAddress)` and `computeSentSat(tx, changeAddress)` helpers. Safe to unit-test; no network, no storage. Uses `SAT_PER_RVN = 100_000_000L` constant. -- Existing `getTransactionHistory` untouched. - -### Task 2: TxHistoryDao alias (commit 955e1a3) -- Added `fun getPage(offset: Int, limit: Int = 20)` alias wrapping existing `page(limit, offset)`. Matches argument order of `RavencoinPublicNode.getHistoryPaged` and reads naturally at WalletScreen call sites. No schema change. - -### Task 3: AppConfig.EXPLORER_URL (commit 0999a5f) -- Added `const val EXPLORER_URL: String = "https://ravencoin.network/tx/"` to both consumer and brand flavor `AppConfig` files. Same value in both. - -### Task 4: AppStrings EN + IT (commit 8e1c899) -- New strings: `txHistorySentPrefix`, `txHistoryCycledPrefix`, `txHistoryFeePrefix`, `txHistoryLoadMore`, `txHistoryEmptyHeading`, `txHistoryEmptyBody`, `txDetailsViewOnExplorer`, `txHistoryConfirmations`. -- EN and IT variants verbatim from UI-SPEC Copywriting Contract. -- "Fee" kept invariant in IT; separator U+00B7 used; zero U+2014 em dashes. - -### Task 5: WalletScreen TxCard rewrite (commit 0aa07d0) -- Outgoing branch now renders three right-aligned value lines: Sent (NotAuthenticRed, SemiBold, `-` prefix), Cycled (AuthenticGreen, labelSmall), Fee (RavenMuted, labelSmall); 2dp gap between value lines, 6dp before the timestamp/conf row. -- Self-transfer variant (`isSelf == true`): single line `Cycled X RVN · Fee Y RVN` with `Icons.Default.Autorenew` in RavenOrange, no Sent line. -- Incoming branch preserved (single green `+X RVN` line with CallReceived icon). -- Confirmation dot color: red at 0 conf, amber `0xFFF59E0B` at 1-5, AuthenticGreen at >=6 (D-08 verified). -- Load more RavenOrange button wired to `TxHistoryDao.getPage(offset, 20)` with `RavencoinPublicNode.getHistoryPaged` fallback that writes shell rows. -- Empty-state composable renders verbatim EN/IT headings and body copy. - -### Task 6: TransactionDetailsScreen three-value breakdown + explorer (commit 17b967a) -- Reads primary source from `TxHistoryDao.findByTxid(txid)` on IO dispatcher; falls back gracefully when no row is cached. -- Outgoing: three rows with icons (CallMade / Autorenew / Payments) and colored amounts (NotAuthenticRed / AuthenticGreen / RavenMuted). -- Self-transfer: Cycled + Fee only (no Sent). -- Incoming: legacy single-amount layout preserved. -- `View on explorer` OutlinedButton (RavenOrange border + content) calls `Intent.ACTION_VIEW` on `AppConfig.EXPLORER_URL + txid`; `ActivityNotFoundException` swallowed silently per ASVS V7. - -## Commits - -| Task | Name | Commit | -|------|------|--------| -| 1 | RavencoinPublicNode.getHistoryPaged + RavencoinTxHistoryMath | 09ae52c | -| 2 | TxHistoryDao.getPage(offset, limit) alias | 955e1a3 | -| 3 | AppConfig.EXPLORER_URL (consumer + brand) | 0999a5f | -| 4 | AppStrings EN + IT for 3-value row + Load more + empty + explorer | 8e1c899 | -| 5 | WalletScreen TxCard three-value row + Load more + empty state | 0aa07d0 | -| 6 | TransactionDetailsScreen three-value breakdown + View on explorer | 17b967a | - -## Verification - -- `./gradlew :app:assembleConsumerDebug` exits 0. -- `./gradlew :app:assembleBrandDebug` exits 0. -- Em-dash audit across all seven touched files: zero U+2014 occurrences. -- Acceptance grep patterns for each task verified against the final file state. - -## Deviations from Plan - -None.

Normalize to a newest-first list: mempool (height == 0) first, then confirmed sorted by height DESC. - - Apply `.drop(offset).take(limit)` client-side. - - Map each entry to `TxHistoryEntry(txid, height, confirmations = (currentHeight - height + 1) if height > 0 else 0, timestamp)`. Skip the expensive per-tx body fetch; pagination does not need tx amounts (they already live in TxHistoryDao once populated). - - If `blockchain.headers.subscribe` is needed for `currentHeight`, use the same batch pattern as the existing `getTransactionHistory`; else reuse any already-cached tip height. - - Wrap the blocking call in `kotlinx.coroutines.withContext(Dispatchers.IO)`. - - On any exception, return `emptyList()` (do NOT rethrow — Load more path must be resilient). - - 2) `object RavencoinTxHistoryMath`: - ```kotlin - object RavencoinTxHistoryMath { - fun computeCycledSat(tx: com.google.gson.JsonObject, changeAddress: String): Long { ... } - fun computeSentSat(tx: com.google.gson.JsonObject, changeAddress: String): Long { ... } - } - ``` - - Semantics: - - `vout` is a `JsonArray` where each element has `value` (RVN as `Double`) and `scriptPubKey.addresses` (a `JsonArray` of `String`). - - `computeCycledSat` sums `value` of outputs whose `scriptPubKey.addresses` contains `changeAddress`, converted from RVN → satoshis (`(value * 1e8).toLong()`). - - `computeSentSat` sums `value` of outputs whose `scriptPubKey.addresses` contains AT LEAST ONE address != `changeAddress`. If an output pays multiple addresses (multi-sig), treat it as "sent" if any address differs from changeAddress (conservative — the user is giving up exclusive control of that output's full value). - - Malformed entries (no `value`, no `addresses`) contribute 0. - - Both functions are PURE (no network, no storage). Safe to unit-test. - - 3) Do NOT touch the existing `getTransactionHistory`. The new helper is deliberately leaner for the Load more path; the existing method remains for the initial WalletScreen render that walks vin/vout for amount attribution. - - Em-dash audit on the touched file. - - - 1) Open `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt`. Find a sensible insertion point for additions: below the existing `getTransactionHistory` method (~line 914-1030) or inside the companion object at the bottom of the class — inspect style and place accordingly. - - 2) Add `getHistoryPaged` as a member function on the RavencoinPublicNode class: - ```kotlin - suspend fun getHistoryPaged( - address: String, - offset: Int, - limit: Int = 20 - ): List = kotlinx.coroutines.withContext(kotlinx.coroutines.Dispatchers.IO) { - try { - val scripthash = addressToScripthash(address) - // Batch: fetch tip height + history in one TLS connection, same as existing getTransactionHistory. - val batch = callWithFailoverBatch(listOf( - "blockchain.headers.subscribe" to emptyList(), - "blockchain.scripthash.get_history" to listOf(scripthash) - )) - val currentHeight = try { - batch[0]?.asJsonObject?.get("height")?.asInt ?: 0 - } catch (_: Exception) { 0 } - val raw = batch[1]?.asJsonArray ?: return@withContext emptyList() - val ordered = raw - .mapNotNull { try { it.asJsonObject } catch (_: Exception) { null } } - .sortedWith(compareByDescending { - val h = it.get("height")?.asInt ?: 0 - if (h <= 0) Int.MAX_VALUE else h // mempool first - }) - .drop(offset) - .take(limit) - ordered.mapNotNull { item -> - val txHash = item.get("tx_hash")?.asString ?: return@mapNotNull null - val height = item.get("height")?.asInt ?: 0 - val confirmations = if (height > 0 && currentHeight > 0) { - (currentHeight - height + 1).coerceAtLeast(0) - } else 0 - TxHistoryEntry( - txid = txHash, - height = height, - confirmations = confirmations, - timestamp = 0L // Lightweight: timestamp not included; caller fills on full fetch if needed. - ) - } - } catch (_: Exception) { - emptyList() - } - } - ``` - - If the existing `TxHistoryEntry` data class has additional required fields (e.g. `blockTime`, `amount`), supply defaults (0L / null / empty string) to keep the constructor call valid. The executor inspects the file for the exact `TxHistoryEntry` signature and adapts. - - 3) Add the helper object at file top-level (below the class body): - ```kotlin - object RavencoinTxHistoryMath { - - private const val SAT_PER_RVN = 100_000_000L - - fun computeCycledSat( - tx: com.google.gson.JsonObject, - changeAddress: String - ): Long { - val vout = try { tx.getAsJsonArray("vout") } catch (_: Exception) { null } - ?: return 0L - var total = 0L - for (element in vout) { - try { - val out = element.asJsonObject - val addresses = out - .getAsJsonObject("scriptPubKey") - ?.getAsJsonArray("addresses") - ?: continue - val hasChange = addresses.any { it.asString == changeAddress } - if (hasChange) { - val rvn = out.get("value")?.asDouble ?: 0.0 - total += (rvn * SAT_PER_RVN).toLong() - } - } catch (_: Exception) { - // skip malformed output - } - } - return total - } - - fun computeSentSat( - tx: com.google.gson.JsonObject, - changeAddress: String - ): Long { - val vout = try { tx.getAsJsonArray("vout") } catch (_: Exception) { null } - ?: return 0L - var total = 0L - for (element in vout) { - try { - val out = element.asJsonObject - val addresses = out - .getAsJsonObject("scriptPubKey") - ?.getAsJsonArray("addresses") - ?: continue - val external = addresses.any { it.asString != changeAddress } - if (external) { - val rvn = out.get("value")?.asDouble ?: 0.0 - total += (rvn * SAT_PER_RVN).toLong() - } - } catch (_: Exception) { - // skip malformed output - } - } - return total - } - } - ``` - - 4) Em-dash audit: `! grep -P '\u2014' android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt`.

Do NOT modify the incoming branch. Add a self-transfer variant (pure consolidation). Add a Load more button and an empty-state composable. - - Visual spec (UI-SPEC §Tx history three-value row): - - Row outer: existing `Card` with `RavenCard` bg, `RavenBorder` border, 12dp radius, padding 14dp/10dp (unchanged). - - Left: existing status dot (10dp) + existing direction icon (16dp `Icons.Default.CallMade` in NotAuthenticRed). Unchanged. - - Middle: existing truncated txid in monospace, RavenMuted, `weight(1f)`. Unchanged. - - Right column: NEW. `Alignment.End`. Gap `2.dp` between the three value lines. Gap `6.dp` before the timestamp/conf row. - - Line 1 ("Sent"): `bodySmall`, FontWeight.SemiBold, color `NotAuthenticRed`. Prefix `"${strings.txHistorySentPrefix} -"` + formatted amount + `" RVN"`. Example: `Sent -5 RVN` (EN), `Inviato -5 RVN` (IT). Decimal styling (10sp decimals) from existing pattern applies — reuse the existing `AnnotatedString` composite used by the balance row. - - Line 2 ("Cycled"): `labelSmall`, FontWeight.Normal, color `AuthenticGreen`. Text `"${strings.txHistoryCycledPrefix} ${amount} RVN"`. - - Line 3 ("Fee"): `labelSmall`, FontWeight.Normal, color `RavenMuted`. Text `"${strings.txHistoryFeePrefix} ${amount} RVN"`. - - Row 4 (timestamp + conf): existing spec. Middle dot `·` separator, format `DD/MM/YY · n/6 conf` (EN). `txHistoryConfirmations` already pluralized. - - Self-transfer variant (when `row.isSelf == true`): - - Collapse Lines 1/2/3 into a SINGLE line: `${strings.txHistoryCycledPrefix} ${cycledAmount} RVN · ${strings.txHistoryFeePrefix} ${feeAmount} RVN`. - - Direction icon replaced with `Icons.Default.Autorenew` in `RavenOrange`. - - No Sent line. - - Everything else (dot color, monospace txid, confirmations row) unchanged. - - Incoming row (`row.isIncoming == true`): UNCHANGED. Keep the existing single-amount layout. - - Confirmation dot color (D-08): verify existing logic behaves as: - - `confirms == 0` → NotAuthenticRed - - `confirms in 1..5` → amber `Color(0xFFF59E0B)` - - `confirms >= 6` → AuthenticGreen - If the existing code does NOT match, correct it in this pass. - - Load more button (UI-SPEC §Primary CTAs): - - Below the LazyColumn (or inside it as the last item), render `Button(onClick = viewModel.loadMore, colors = ButtonDefaults.buttonColors(containerColor = RavenOrange))` with text `strings.txHistoryLoadMore`. - - Only visible when `TxHistoryDao.count() > currentlyDisplayed` OR when a next-page fetch is likely to succeed (simpler heuristic: always visible while the last page returned `limit` rows). - - `loadMore()` behavior (in the ViewModel or inline lambda here): - 1. Compute `offset = currentList.size`. - 2. Call `TxHistoryDao.getPage(offset = offset, limit = 20)`. - 3. If result is empty, fall back to `RavencoinPublicNode.getHistoryPaged(address, offset = offset, limit = 20)` via `kotlinx.coroutines.launch`. - 4. Append returned rows to the displayed list. - - Empty state (UI-SPEC §Empty states): - - When the displayed list is empty AND no refresh is in progress, render a centered Column inside the history section: - - Text `strings.txHistoryEmptyHeading` titleSmall SemiBold white. - - Spacer 8dp. - - Text `strings.txHistoryEmptyBody` bodySmall RavenMuted, textAlign = Center. - - No modifications to the header / banner / connection pill / Pending line / battery chip — those were installed by plan 30-08. - - Em-dash audit on WalletScreen.kt. - - - 1) Read WalletScreen.kt. Identify the existing `TxCard` composable. Typical structure: - ```kotlin - @Composable - private fun TxCard(tx: TxHistoryEntry, ...) { - Card(... ) { - Row(... ) { - // dot, icon, txid, amount - } - } - } - ``` - If `TxCard` currently takes `TxHistoryEntry` only (Phase 20), adapt it to take `TxHistoryRow` from `TxHistoryDao` instead. If the WalletScreen currently iterates over `TxHistoryEntry` (from network fetch), introduce a `displayedRows: List` state that is filled from `TxHistoryDao.getPage(offset = 0, limit = 20)` on first load, replacing the network-sourced list. Preserve the initial fetch that WRITES to `TxHistoryDao` (plan 30-05 already ensures the send path writes; plan 30-08 triggers refresh; this plan just reads). - - 2) Implement the rewritten `TxCard`: - ```kotlin - @Composable - private fun TxCard(row: io.raventag.app.wallet.cache.TxHistoryDao.TxHistoryRow) { - val strings = io.raventag.app.ui.theme.LocalStrings.current - val dotColor = when { - row.confirms == 0 -> io.raventag.app.ui.theme.NotAuthenticRed - row.confirms in 1..5 -> androidx.compose.ui.graphics.Color(0xFFF59E0B) - else -> io.raventag.app.ui.theme.AuthenticGreen - } - - Card( - colors = CardDefaults.cardColors(containerColor = io.raventag.app.ui.theme.RavenCard), - border = androidx.compose.foundation.BorderStroke(1.dp, io.raventag.app.ui.theme.RavenBorder), - shape = androidx.compose.foundation.shape.RoundedCornerShape(12.dp), - modifier = Modifier.fillMaxWidth().padding(vertical = 4.dp) - ) { - Row( - modifier = Modifier.fillMaxWidth().padding(horizontal = 14.dp, vertical = 10.dp), - verticalAlignment = androidx.compose.ui.Alignment.CenterVertically - ) { - // Left: dot + direction icon - Box(Modifier.size(10.dp).background(dotColor, CircleShape)) - Spacer(Modifier.width(8.dp)) - val (dirIcon, dirTint) = when { - row.isSelf -> Icons.Default.Autorenew to io.raventag.app.ui.theme.RavenOrange - row.isIncoming -> Icons.Default.CallReceived to io.raventag.app.ui.theme.AuthenticGreen - else -> Icons.Default.CallMade to io.raventag.app.ui.theme.NotAuthenticRed - } - Icon(dirIcon, contentDescription = null, tint = dirTint, modifier = Modifier.size(16.dp)) - Spacer(Modifier.width(8.dp)) - - // Middle: truncated txid - Text( - text = row.txid.take(10) + "\u2026", - style = MaterialTheme.typography.bodySmall.copy(fontFamily = FontFamily.Monospace), - color = io.raventag.app.ui.theme.RavenMuted, - modifier = Modifier.weight(1f) - ) - - // Right column - Column(horizontalAlignment = androidx.compose.ui.Alignment.End) { - when { - row.isIncoming -> { - // UNCHANGED incoming layout (single amount + timestamp + confs). - val rvn = String.format(java.util.Locale.ROOT, "%.8f", row.amountSat / 1e8) - Text( - text = "+$rvn RVN", - style = MaterialTheme.typography.bodySmall, - fontWeight = FontWeight.SemiBold, - color = io.raventag.app.ui.theme.AuthenticGreen - ) - } - row.isSelf -> { - val cycled = String.format(java.util.Locale.ROOT, "%.8f", row.cycledSat / 1e8) - val fee = String.format(java.util.Locale.ROOT, "%.8f", row.feeSat / 1e8) - Text( - text = "${strings.txHistoryCycledPrefix} $cycled RVN \u00B7 ${strings.txHistoryFeePrefix} $fee RVN", - style = MaterialTheme.typography.labelSmall, - color = io.raventag.app.ui.theme.AuthenticGreen - ) - } - else -> { - val sent = String.format(java.util.Locale.ROOT, "%.8f", row.sentSat / 1e8) - val cycled = String.format(java.util.Locale.ROOT, "%.8f", row.cycledSat / 1e8) - val fee = String.format(java.util.Locale.ROOT, "%.8f", row.feeSat / 1e8) - Text( - text = "${strings.txHistorySentPrefix} -$sent RVN", - style = MaterialTheme.typography.bodySmall, - fontWeight = FontWeight.SemiBold, - color = io.raventag.app.ui.theme.NotAuthenticRed - ) - Spacer(Modifier.height(2.dp)) - Text( - text = "${strings.txHistoryCycledPrefix} $cycled RVN", - style = MaterialTheme.typography.labelSmall, - color = io.raventag.app.ui.theme.AuthenticGreen - ) - Spacer(Modifier.height(2.dp)) - Text( - text = "${strings.txHistoryFeePrefix} $fee RVN", - style = MaterialTheme.typography.labelSmall, - color = io.raventag.app.ui.theme.RavenMuted - ) - } - } - Spacer(Modifier.height(6.dp)) - // Timestamp + conf row - val ts = if (row.timestamp > 0L) { - java.text.SimpleDateFormat("dd/MM/yy", java.util.Locale.getDefault()) - .format(java.util.Date(row.timestamp * 1000L)) - } else "" - val conf = String.format(strings.txHistoryConfirmations, row.confirms.coerceAtMost(6)) - Text( - text = if (ts.isEmpty()) conf else "$ts \u00B7 $conf", - style = MaterialTheme.typography.labelSmall, - color = io.raventag.app.ui.theme.RavenMuted - ) - } - } - } - } - ``` - - 3) Replace the LazyColumn's `items(txHistory)` iterator with `items(displayedRows) { TxCard(it) }`. Adapt `displayedRows` type to `List`. - - 4) Add the Load more button below the LazyColumn items (or as the final item): - ```kotlin - item { - Spacer(Modifier.height(8.dp)) - Button( - onClick = { scope.launch { loadMore() } }, - colors = ButtonDefaults.buttonColors(containerColor = io.raventag.app.ui.theme.RavenOrange), - modifier = Modifier.fillMaxWidth() - ) { Text(strings.txHistoryLoadMore) } - } - ``` - - 5) Implement `loadMore()`: - ```kotlin - suspend fun loadMore() { - val offset = displayedRows.size - val local = io.raventag.app.wallet.cache.TxHistoryDao.getPage(offset = offset, limit = 20) - if (local.isNotEmpty()) { - displayedRows = displayedRows + local - } else { - val addr = walletInfo.currentReceiveAddress - val serverPage = io.raventag.app.wallet.RavencoinPublicNode(context) - .getHistoryPaged(address = addr, offset = offset, limit = 20) - // Materialize into TxHistoryRow shells (amount data missing — rely on next refresh to enrich). - val shells = serverPage.map { entry -> - io.raventag.app.wallet.cache.TxHistoryDao.TxHistoryRow( - txid = entry.txid, - height = entry.height, - confirms = entry.confirmations, - amountSat = 0L, sentSat = 0L, cycledSat = 0L, feeSat = 0L, - isIncoming = false, isSelf = false, - timestamp = entry.timestamp, - cachedAt = System.currentTimeMillis() - ) - } - if (shells.isNotEmpty()) { - io.raventag.app.wallet.cache.TxHistoryDao.upsert(shells) - displayedRows = displayedRows + shells - } - } - } - ``` - - 6) Empty state: - ```kotlin - if (displayedRows.isEmpty() && !isRefreshing) { - Column( - modifier = Modifier.fillMaxWidth().padding(vertical = 32.dp), - horizontalAlignment = androidx.compose.ui.Alignment.CenterHorizontally - ) { - Text( - text = strings.txHistoryEmptyHeading, - style = MaterialTheme.typography.titleSmall, - fontWeight = FontWeight.SemiBold, - color = Color.White - ) - Spacer(Modifier.height(8.dp)) - Text( - text = strings.txHistoryEmptyBody, - style = MaterialTheme.typography.bodySmall, - color = io.raventag.app.ui.theme.RavenMuted, - textAlign = androidx.compose.ui.text.style.TextAlign.Center, - modifier = Modifier.fillMaxWidth() - ) - } - } - ``` - - 7) On first composition (or as part of the existing WalletScreen `LaunchedEffect`), seed `displayedRows` from `TxHistoryDao.getPage(offset = 0, limit = 20)`.

Tested working. -- **ConnectionHealthPill dot content description:** The plan proposed a static "Connection status" label. Implementation concatenates the live label (Online/Reconnecting/Offline) so talkback announces the current state rather than a generic phrase. This is a minor UX improvement consistent with Rule 2 (accessibility correctness). -- **BatterySaverChip:** The inner icon previously had a hard-coded English `contentDescription = "Battery saver enabled"`. Moved to parent Card via AppStrings (localized) and set inner icon to `null` to prevent double-announce. - -## Phase 30 Overall Outcome - -All 10 plans complete (30-01 through 30-10): - -| Plan | Focus | Status | -|------|-------|--------| -| 30-01 | Wave 0 test scaffolding | Complete | -| 30-02 | Wallet Cache DB DAOs | Complete | -| 30-03 | Scripthash subscription | Complete | -| 30-04 | Fee estimation | Complete | -| 30-05 | Consolidation reliability | Complete | -| 30-06 | Mnemonic safety | Complete | -| 30-07 | Node reliability | Complete | -| 30-08 | WalletScreen refresh + receive UX | Complete | -| 30-09 | Tx history three-value row | Complete | -| 30-10 | Housekeeping (this plan) | Complete | - -## ROADMAP Success Criteria Coverage - -| Criterion | Requirement ID | Status | -|-----------|----------------|--------| -| RVN balance matches ElectrumX state | WALLET-BAL | Met (30-02, 30-03, 30-08) | -| Send RVN transactions broadcast successfully | WALLET-SEND | Met (30-05) | -| Receive RVN detects incoming transactions | WALLET-RECV | Met (30-03, 30-08) | -| UTXO set accurately reflects blockchain state | WALLET-UTXO | Met (30-02, 30-05) | -| Mnemonic can be safely exported/imported | WALLET-MNEM | Met (30-06) | -| Keystore protected from extraction | WALLET-KEYS | Met (30-06) | - -## Hand-off Notes - -- **Next phase:** Phase 40 — Asset Emission UX (not yet planned). -- **Deferred housekeeping:** `RavencoinTxBuilder.kt:907,908` em-dash in comments (see `deferred-items.md`).

Scope covers: sync cadence and state caching, receive detection via ElectrumX subscriptions, multi-node failover with TOFU fingerprint quarantine, mnemonic export/import safety, keystore integrity, fee estimation, transaction history display, mempool/stuck-tx handling, asset-UTXO reservation during consolidation, power-save behavior, and the speed/reliability optimization of the existing quantum-resistance consolidation pattern. - -Out of scope: backend stability (Phase 50), asset emission UX (Phase 40), security hardening already completed in Phase 10, and the async conversion work already completed in Phase 20. - - - - -## Implementation Decisions - -### Balance & UTXO Sync -- **D-01:** Sync triggers are both (a) on app foreground / WalletScreen resume and (b) periodic poll while WalletScreen is visible. No manual-only mode. -- **D-02:** Periodic poll interval is 30 seconds while WalletScreen is in foreground. -- **D-03:** On balance vs UTXO-sum mismatch, trust `sum(utxo.value)` as displayed spendable balance. Log the discrepancy (structured log, no user-visible error). -- **D-04:** Persist last-known wallet state (balance, UTXOs, recent tx history) in SQLite. On WalletScreen open, render cached state instantly with a "Last updated HH:MM" indicator, then refresh in background. - -### Receive Detection -- **D-05:** Primary detection is ElectrumX `blockchain.scripthash.subscribe` per wallet address while app is foreground. Subscription delivers near-instant mempool + confirmation notifications. -- **D-06:** Background detection runs via Android WorkManager periodic job every 15 minutes when app is closed. Fires system notification on new tx. -- **D-07:** On new incoming tx, user sees ALL of: in-app banner/snackbar, system notification, balance auto-update, and new entry in transaction history list with confirmation progress. -- **D-08:** A received transaction is considered final in UI at 6 confirmations. Until then show `N/6 confirmations` progress. Unconfirmed (mempool) shows as "Pending". - -### Node Reliability & Failover -- **D-09:** Hardcoded fallback list of ~3-5 known public ElectrumX nodes. Round-robin on connection/RPC failure. No user-configurable list in this phase. -- **D-10:** Per-node TLS timeouts: 10s connect / 20s RPC. Matches current NetworkModule effective timeouts. -- **D-11:** TOFU fingerprint mismatch → quarantine node for 1 hour, then retry. If still mismatched, keep quarantined. Logged but not surfaced to user. -- **D-12:** Degraded-state UX: connection status badge on WalletScreen (green / yellow / red pill), stale-balance indicator ("Last updated HH:MM · reconnecting…") when fetch fails, Send/Receive actions disabled when ALL fallback nodes have failed. Transient flakiness does not change UI. - -### Mnemonic Export / Import -- **D-13:** Export format for v1: 12/24-word phrase display with copy-to-clipboard only. QR and encrypted-file formats are deferred to a future phase. -- **D-14:** Import/restore verification requires ALL of: BIP39 checksum validation, confirmation dialog naming the current wallet's balance/assets ("will replace current wallet X RVN, Y assets — cannot be undone"), and a forced current-wallet backup step before import is allowed when current wallet has non-zero balance. -- **D-15:** Keystore integrity: detect `KeyPermanentlyInvalidatedException` on decrypt and route user to re-auth or mnemonic restore; require BiometricPrompt (fingerprint/face/PIN) before revealing mnemonic words; store HMAC of seed alongside ciphertext and verify on load. -- **D-16:** Never cache decrypted mnemonic in memory after use. Re-decrypt from Android Keystore on every operation. Clear char arrays after use. - -### Quantum-Resistance Consolidation (CRITICAL) -- **D-17:** The wallet already implements a quantum-resistance consolidation pattern that must be preserved, optimized for speed and reliability, and remain invisible to the end user. Rules: - - When the user sends RVN or assets to an external address, the wallet constructs an atomic transaction that (a) sends the requested amount to the external address, (b) sweeps all remaining RVN and any assets on the sending address to a new never-spent address at `currentIndex + 1`. - - When RVN or assets arrive at an old address (derivation index < `currentIndex`), the wallet auto-consolidates those funds to a new never-spent address at `currentIndex + 1`. If an old address receives only assets and has no RVN to fund the consolidation tx, the wallet funds it from `currentIndex` (which therefore becomes spent — `currentIndex` must then advance to `currentIndex + 1`). - - Rationale: unspent P2PKH addresses do not expose their public key on-chain (only the RIPEMD160-SHA256 hash). Keeping the active balance on a never-spent address protects against hypothetical quantum attackers who could derive the private key from the public key. - - This phase's job is NOT to add this behavior (already works) but to make it faster and more reliable. -- **D-18:** Receive address strategy: ReceiveScreen always displays the current `currentIndex` never-spent address. After any external send or auto-consolidation, the displayed address advances to the new `currentIndex`. No per-receive rotation — the quantum-resistance model IS the rotation. -- **D-19:** Transaction history must display outgoing transactions with three explicit values visible to the user: - 1. Amount sent to external address (e.g., `-5 RVN to R...`) - 2. Amount cycled to new never-spent address (e.g., `245 - fee RVN → new address`) - 3. Fee paid (e.g., `Fee: 0.0012 RVN`) - Example: user has 250 RVN, sends 5 to external address. History row shows: `Sent 5 RVN · Cycled 244.9988 RVN · Fee 0.0012 RVN`. -- **D-20:** Asset/RVN UTXOs reserved by a pending consolidation are locked in a SQLite `reserved_utxos(txid_in, vout, tx_submitted_at)` table on tx submit. Rows removed on confirm or detected drop. Displayed spendable balance = `sum(confirmed_utxo) - sum(reserved_utxo)`. -- **D-21:** Consolidation failure recovery: silent retry with Phase 20 backoff policy (5× exp backoff). If still failing, persist a `pending_consolidation` flag and retry on next wallet refresh / app foreground. User is notified only if the pending-consolidation state has persisted across multiple blocks (funds exposed). Never block new sends on a pending consolidation — throughput matters more than strict sequential consolidation. - -### Fee Estimation -- **D-22:** Fees are determined dynamically via ElectrumX `blockchain.estimatefee` (target ~6 blocks) and shown in the send confirmation dialog (Phase 20 D-07), with an editable override field. Consolidation txs use the same logic. Fallback to a safe static rate (0.01 RVN/kB) when estimatefee is unavailable. - -### Transaction History -- **D-23:** WalletScreen shows the last 20 transactions inline with a "Load more" button. Older history is paged backwards via ElectrumX `blockchain.scripthash.get_history`. Transactions cached in SQLite for offline display. - -### Mempool & Stuck Transactions -- **D-24:** Unconfirmed incoming mempool outputs are NOT counted as spendable balance. They appear as a separate "Pending" line on WalletScreen. Spendable = confirmed UTXOs only (minus reserved, per D-20). -- **D-25:** Outgoing transactions that remain unconfirmed are auto-rebroadcast to all fallback nodes after N minutes (suggested 30 min; tunable). Silent — no user-facing action required. - -### Power Save Behavior -- **D-26:** When `PowerManager.isPowerSaveMode()` is true, pause the 30s periodic poll; keep the ElectrumX scripthash subscription open (push-based, minimal cost). -- **D-27:** Consolidation transactions always broadcast regardless of power-save / data-saver state. Security-critical — must not be throttled. -- **D-28:** When sync is in a reduced mode, surface a small status indicator on WalletScreen ("Battery saver — manual refresh recommended") to prevent stale-balance confusion. - -### Claude's Discretion -- Exact SQLite schema for wallet state cache, reserved UTXOs, and transaction history tables. -- Notification channel configuration for incoming tx (separate from transaction_progress channel introduced in Phase 20). -- Exact WorkManager scheduling parameters (backoff, constraints, initial delay). -- Compose UI details for connection status badge, pending-balance line, and tx history row layout showing the three values from D-19. -- Coroutine/flow architecture for subscription delivery → UI state updates. -- Exact fallback ElectrumX node list (defer to researcher to gather current public nodes). -- Retry/backoff constants not already fixed by Phase 20 D-02. - - - - -## Canonical References - -**Downstream agents MUST read these before planning or implementing.** - -### Wallet Core -- `android/app/src/main/java/io/raventag/app/wallet/WalletManager.kt` — HD wallet, restore, send, consolidation logic (`currentIndex` management lives here) -- `android/app/src/main/java/io/raventag/app/wallet/RavencoinPublicNode.kt` — ElectrumX client (scripthash, balance, UTXO, history, estimatefee, subscribe RPC) -- `android/app/src/main/java/io/raventag/app/wallet/RavencoinTxBuilder.kt` — Tx construction, signing, asset + consolidation outputs -- `android/app/src/main/java/io/raventag/app/wallet/AssetManager.kt` — Asset-aware UTXO handling, admin operations -- `android/app/src/main/java/io/raventag/app/worker/WalletPollingWorker.kt` — Background polling (to be extended for D-06) - -### Wallet UI -- `android/app/src/main/java/io/raventag/app/ui/screens/WalletScreen.kt` — Balance display, tx history, send entry -- `android/app/src/main/java/io/raventag/app/ui/screens/SendRvnScreen.kt` — RVN send flow -- `android/app/src/main/java/io/raventag/app/ui/screens/ReceiveScreen.kt` — Receive address display (must always show currentIndex per D-18) -- `android/app/src/main/java/io/raventag/app/ui/screens/TransferScreen.kt` — Asset transfer flow -- `android/app/src/main/java/io/raventag/app/ui/screens/TransactionDetailsScreen.kt` — Individual tx view -- `android/app/src/main/java/io/raventag/app/ui/screens/MnemonicBackupScreen.kt` — Mnemonic export entry point (D-13, D-15) - -### Network / Config -- `android/app/src/main/java/io/raventag/app/network/NetworkModule.kt` — OkHttp timeouts (D-10);

The phase is a reliability hardening pass: add ElectrumX scripthash subscription, persist wallet state cache, wire biometric gate for mnemonic reveal, handle Keystore invalidation, reserve UTXOs during pending consolidations, and display the three-value outgoing tx breakdown (D-19). - -The Kotlin/Android Ravencoin ecosystem is thin. No stable Kotlin ElectrumX client library exists; the existing hand-rolled raw-socket TLS client in `RavencoinPublicNode.kt` is the standard approach. Vanilla Bitcoin mobile-wallet reliability patterns (BlueWallet style) apply directly: time-based + event-triggered polling, conservative confirmation depth (6 for Bitcoin; already chosen for this phase), and SQLite-backed state cache with `last_updated_at`. Ravencoin's 1-minute block time means "6 confirmations" = ~6 minutes (vs ~60 min for Bitcoin) — acceptable UX. - -**Primary recommendation:** Treat the existing raw-socket `RavencoinPublicNode` as the mandatory client (no library migration). Add a second persistent socket per ElectrumX session for subscription push notifications (cannot share the request/response socket because subscription notifications arrive asynchronously and would interleave with RPC responses). Use Kotlin `Flow` to deliver events upward, re-emitted from a singleton `SubscriptionManager`. Cache wallet state in a dedicated SQLite DB (same pattern as Phase 10 TOFU). Keep D-17 consolidation semantics identical — this phase only speeds it up and adds D-20 reservation. - -## Architectural Responsibility Map - -| Capability | Primary Tier | Secondary Tier | Rationale | -|------------|-------------|----------------|-----------| -| Balance query + UTXO fetch | Android ElectrumX client (raw socket) | — | Already lives in `RavencoinPublicNode`; ElectrumX is the ground truth for Ravencoin chain state | -| Wallet state cache | Android SQLite (app-local) | — | D-04 persistence; no server component trustless design prohibits server-side wallet state | -| Scripthash subscription | Android long-lived TCP socket | — | Push notifications require a dedicated socket; backend is not involved | -| Mnemonic encryption at rest | Android Keystore + EncryptedSharedPreferences | — | Security-critical; already Phase 10 pattern | -| Biometric gate for reveal | Android `BiometricPrompt` + `CryptoObject` | Keystore | D-15; must bind biometric auth to the actual decrypt op, not a boolean flag | -| Fee estimation | Android ElectrumX client (`blockchain.estimatefee`) | Static fallback 0.01 RVN/kB | D-22; backend never proxies fee queries — trustless model | -| Background receive polling | Android WorkManager | ElectrumX client | D-06; system-managed periodic job, cannot depend on app lifecycle | -| Transaction broadcast | Android ElectrumX client (`blockchain.transaction.broadcast`) | Fallback to remaining nodes | Send flow already implements failover in `broadcast()` | -| Reserved UTXO tracking | Android SQLite | — | D-20 local bookkeeping; ElectrumX has no concept of reserved UTXOs | -| Connection status badge | Android UI state (Compose) | `SubscriptionManager` + `ElectrumHealthMonitor` | Derived state from client; not persisted | - -## Standard Stack - -### Core — already shipped, keep as-is - -| Library | Version | Purpose | Why Standard | -|---------|---------|---------|--------------| -| BouncyCastle `bcprov-jdk15to18` | 1.77 | AES-CMAC, HMAC-SHA512 (BIP32), ECDSA (secp256k1), RIPEMD160 | [VERIFIED: STACK.md line 126] Already wired; no external BIP32/39/44 deps, mnemonic wordlist embedded | -| Android Keystore AES-GCM | API 26+ | Mnemonic encryption at rest, StrongBox when available | [VERIFIED: WalletManager.kt:254-289] Existing impl; includes `setUnlockedDeviceRequired(true)` on API 28+ | -| EncryptedSharedPreferences | 1.1.0-alpha06 | Secondary secret storage (admin key, flags) | [VERIFIED: Phase 10 pattern] Already used for AdminKeyStorage | -| SQLiteOpenHelper | Android platform | Persistent caches (TOFU, wallet state, reserved UTXOs, tx history) | [VERIFIED: TofuFingerprintDao.kt] Same pattern reused | -| kotlinx-coroutines-android | 1.7.3 | Suspend functions, `async`/`awaitAll`, `Flow` | [VERIFIED: Phase 20] `retryWithBackoff` + `withContext(Dispatchers.IO)` pattern established | -| WorkManager `work-runtime-ktx` | 2.9.1 | Background periodic receive detection (D-06) | [VERIFIED: WalletPollingWorker.kt] Already in place; extend for scripthash-status comparison | -| Gson | 2.10.1 | JSON-RPC request/response serialization | [VERIFIED: RavencoinPublicNode.kt:5-8] | -| androidx.biometric | 1.1.0 | `BiometricPrompt` + `CryptoObject` for D-15 | [VERIFIED: STACK.md line 142] Declared but not yet consumed in wallet flow | - -### Supporting — new in Phase 30 - -| Library | Version | Purpose | When to Use | -|---------|---------|---------|-------------| -| `androidx.work:work-runtime-ktx` | 2.9.1 | Extend existing worker for scripthash-status comparison | D-06 background incoming detection | -| **No new libraries required** | — | — | All Phase 30 work uses the established stack | - -### Alternatives Considered (and rejected) - -| Instead of | Could Use | Why Rejected | -|------------|-----------|--------------| -| Hand-rolled raw-socket ElectrumX client | `bitcoin-kit-android` (Horizontal Systems) | [CITED: github.com/horizontalsystems/bitcoin-kit-android] No Ravencoin support; asset layer (OP_RVN_ASSET) not compatible with their script engine.

Torn down on screen-leave or app-background. - -**Why a separate socket:** ElectrumX subscription notifications are pushed asynchronously (no request ID). If they arrive while a one-shot RPC is in-flight on the same socket, the current client (synchronous `reader.readLine()`) would receive the wrong line. Separate sockets avoid this entire class of bug. - -**Example (reference pattern to port, not copy verbatim):** -```kotlin -// Source: ElectrumX protocol docs (https://electrumx.readthedocs.io/en/latest/protocol-methods.html) -// pattern adapted to existing RavencoinPublicNode.TofuTrustManager -class SubscriptionManager(private val context: Context) { - private val scope = CoroutineScope(SupervisorJob() + Dispatchers.IO) - private var session: Session? = null - private val events = MutableSharedFlow(extraBufferCapacity = 64) - - fun eventsFlow(): SharedFlow = events.asSharedFlow() - - suspend fun start(addresses: List) = withContext(Dispatchers.IO) { - stop() - for (server in SERVERS) { - try { - session = openSession(server) - // handshake + one subscribe call per address - for (addr in addresses) { - session!!.subscribe(scriptHashOf(addr)) - } - // launch reader loop - scope.launch { session!!.readLoop(events) } - return@withContext - } catch (_: Exception) { /* try next server */ } - } - events.emit(ScripthashEvent.AllNodesDown) - } - - suspend fun stop() { session?.close(); session = null } -} - -sealed class ScripthashEvent { - data class StatusChanged(val scripthash: String, val newStatus: String?) : ScripthashEvent() - data object ConnectionLost : ScripthashEvent() - data object AllNodesDown : ScripthashEvent() -} -``` - -Keep the `TofuTrustManager` from `RavencoinPublicNode` — same TOFU rules apply to the subscription socket. - -### Pattern 2: BiometricPrompt Bound to the Decrypt Operation (D-15) - -**What:** `BiometricPrompt.authenticate(promptInfo, CryptoObject(cipher))` where `cipher` is `Cipher.DECRYPT_MODE`-initialized with the Keystore AES-GCM key and the stored IV. Only after successful auth does the OS return a usable `CryptoObject` from which `doFinal(ciphertext)` returns the plaintext mnemonic. - -**When to use:** D-15 mnemonic reveal in MnemonicBackupScreen. NOT for ordinary send operations (those just use the existing `getMnemonic()` which reads Keystore via `setUnlockedDeviceRequired(true)`). - -**Why CryptoObject (not just a boolean gate):** A boolean "user authenticated" flag can be tampered with by a rooted device or a modified APK. CryptoObject binds the auth to the actual decrypt: no auth, no plaintext. [CITED: developer.android.com/training/sign-in/biometric-auth] - -**Example pattern (to be written for the phase):** -```kotlin -// Source: https://medium.com/androiddevelopers/using-biometricprompt-with-cryptoobject-how-and-why-aace500ccdb7 -fun revealMnemonic(activity: FragmentActivity, onResult: (Result) -> Unit) { - val cipher = Cipher.getInstance("AES/GCM/NoPadding").apply { - try { - init(Cipher.DECRYPT_MODE, getOrCreateAndroidKey(), GCMParameterSpec(128, loadIv())) - } catch (e: KeyPermanentlyInvalidatedException) { - onResult(Result.failure(KeyInvalidatedException())) // route user to restore (D-15) - return - } - } - val prompt = BiometricPrompt(activity, ContextCompat.getMainExecutor(activity), - object : BiometricPrompt.AuthenticationCallback() { - override fun onAuthenticationSucceeded(result: BiometricPrompt.AuthenticationResult) { - val plaintext = result.cryptoObject!!.cipher!!.doFinal(loadCiphertext()) - onResult(Result.success(String(plaintext, Charsets.UTF_8))) - // caller MUST overwrite `plaintext` with zeros after display (D-16) - } - override fun onAuthenticationError(code: Int, msg: CharSequence) { - onResult(Result.failure(BiometricCancelledException())) - } - }) - prompt.authenticate( - BiometricPrompt.PromptInfo.Builder() - .setTitle("Authenticate") - .setSubtitle("Reveal recovery phrase") - .setAllowedAuthenticators(BIOMETRIC_STRONG or DEVICE_CREDENTIAL) - .build(), - BiometricPrompt.CryptoObject(cipher) - ) -} -``` - -### Pattern 3: Wallet State Cache (D-04) - -**What:** Single-row SQLite table keyed by wallet ID (the root xpub's hash160 is fine, or just `"default"` since this is a single-wallet app). Columns: serialized balance, UTXO JSON, last-refreshed timestamp. Tx history lives in a separate paginated table (D-23). - -**Why SQLite over EncryptedSharedPreferences:** Balance is not secret (derivable from any address). UTXO JSON can grow. Tx history needs pagination. Reserved UTXOs need compound-key queries. SharedPrefs serializes entire file on every write — unacceptable for 500-row tx tables. - -**Schema (recommended, Claude's discretion per CONTEXT.md):** -```sql --- 1) wallet_state_cache: single row for fast "open WalletScreen" render -CREATE TABLE wallet_state_cache ( - wallet_id TEXT PRIMARY KEY, - balance_sat INTEGER NOT NULL, -- sum(utxo.value) - sum(reserved.value) at write time - utxos_json TEXT NOT NULL, -- JSON array of Utxo - asset_utxos_json TEXT NOT NULL, -- JSON map {asset_name -> [AssetUtxo]} - block_height INTEGER NOT NULL, -- tip height at time of cache write - last_refreshed_at INTEGER NOT NULL -- unix millis -); - --- 2) tx_history: paginated per D-23 -CREATE TABLE tx_history ( - txid TEXT PRIMARY KEY, - height INTEGER NOT NULL, -- 0 = mempool - confirms INTEGER NOT NULL, - amount_sat INTEGER NOT NULL, -- positive = incoming - sent_sat INTEGER NOT NULL, -- positive = amount sent externally (D-19 "sent") - cycled_sat INTEGER NOT NULL, -- positive = amount consolidated to currentIndex+1 (D-19 "cycled") - fee_sat INTEGER NOT NULL, -- D-19 "fee" - is_incoming INTEGER NOT NULL, -- 0/1 - is_self INTEGER NOT NULL, -- consolidation self-transfer - timestamp INTEGER NOT NULL, -- block header unix seconds - cached_at INTEGER NOT NULL -); -CREATE INDEX idx_tx_history_height ON tx_history(height DESC); - --- 3) reserved_utxos: D-20 -CREATE TABLE reserved_utxos ( - txid_in TEXT NOT NULL, -- input txid - vout INTEGER NOT NULL, - tx_submitted_at INTEGER NOT NULL, -- used by D-25 auto-rebroadcast timer - submitted_txid TEXT NOT NULL, -- the consolidation tx we submitted - PRIMARY KEY(txid_in, vout) -); -CREATE INDEX idx_reserved_submitted_txid ON reserved_utxos(submitted_txid); - --- 4) pending_consolidations: D-21 recovery flag -CREATE TABLE pending_consolidations ( - submitted_txid TEXT PRIMARY KEY, - submitted_at INTEGER NOT NULL, - last_retry_at INTEGER, - retry_count INTEGER NOT NULL DEFAULT 0, - last_error TEXT -); - --- 5) quarantined_nodes: D-11 -CREATE TABLE quarantined_nodes ( - host TEXT PRIMARY KEY, - quarantined_until INTEGER NOT NULL, -- unix millis, node skipped while now < this - reason TEXT NOT NULL -- TOFU_MISMATCH | RPC_FAILED | TIMEOUT -); -``` - -### Pattern 4: Confirmation Depth as the Reorg Defense (D-08) - -**What:** Do NOT implement active reorg detection on mobile. Use `confirmations >= 6` as the "final" threshold and re-fetch tx confirmations on every WalletScreen open. If a reorg invalidates a tx, ElectrumX will return the updated status (or drop it from the history response) and the local cache will be overwritten on next refresh. - -**When to use:** Always for a consumer wallet at this scale. - -**Why:** [VERIFIED via bitcoin.stackexchange.com/questions/114985] 6 confirmations is the industry-standard threshold where reorg probability is negligible (<0.00001% under 30% attacker hashrate). Active reorg detection via `blockchain.headers.subscribe` is justified for exchanges and hot wallets, not consumer wallets. Complexity cost > benefit. - -**Ravencoin-specific note:** 1-minute block time means 6 confirmations = ~6 minutes. At 1% difficulty disruption (KAWPOW is ASIC-resistant but not attack-proof), 6 confirmations is still comfortably safe. - -### Pattern 5: Reserved UTXO Bookkeeping (D-20) - -**What:** When `sendRvnLocal` broadcasts a tx, INSERT each input `(txid_in, vout)` into `reserved_utxos`. On subsequent UTXO fetches, subtract reserved rows from the UTXO set before computing spendable balance. On tx confirmation (via subscription event or next poll that finds the tx confirmed in history), DELETE the matching rows. - -**Why needed:** ElectrumX returns the raw chain UTXO set. Between submitting a consolidation tx and its first confirmation, the old UTXOs still appear as "unspent" but will become invalid the moment the consolidation confirms. Without reservation, the user could try to send twice — and while ElectrumX would reject the second broadcast (double-spend), the UI would show a confusing "insufficient funds" error. - -**Cleanup trigger:** `ReservedUtxoDao.deleteForTxid(submittedTxid)` on observing the submitted tx in the confirmed history OR on detecting it was dropped from mempool (D-25). - -### Anti-Patterns to Avoid - -- **Subscribing on the request socket.** Do not call `blockchain.scripthash.subscribe` on the one-shot RPC socket used by `RavencoinPublicNode.call()`. Subscription notifications are push-based and will interleave with synchronous response reads. Use a separate socket. -- **Caching decrypted mnemonic in memory (violates D-16).** Even for the duration of one send, decrypt, use, zero-fill. Do not stash it in a ViewModel property "for convenience." -- **Trusting `blockchain.scripthash.subscribe` status hash as wallet state.** The status hash is a fingerprint (SHA-256 of a concatenated history string). It signals "something changed" — not what. Always re-fetch balance/utxo/history after a status-change notification. -- **Using a single blocking polling loop that also handles subscriptions.** The 30s poll (D-02) and subscription events (D-05) are orthogonal. Poll drives catch-up; subscription drives real-time. Collapsing them causes missed events during slow polls. -- **Broadcasting stuck-tx rebroadcasts without a backoff ceiling.** D-25 auto-rebroadcast must cap retries (recommended: 5 rebroadcasts total over 24h, exponential intervals 30m/1h/2h/4h/8h). Unbounded rebroadcast is a node DoS and won't help if the tx is actually double-spent. -- **Persisting the Keystore SecretKey.** The AES-GCM key is generated in the Keystore and never leaves it. Only the ciphertext and IV are persisted. Regenerating the key means the old ciphertext is permanently unreadable — which is actually what D-15 wants on `KeyPermanentlyInvalidatedException`. -- **Treating `blockchain.relayfee` as a fee estimate.** Relayfee is the minimum to enter mempool, not a confirmation-target estimate. Phase 20's existing `getMinRelayFeeRateSatPerByte` applies a 2× safety margin but is still a floor, not a target. D-22 explicitly uses `blockchain.estimatefee(6)` for normal sends; relayfee is only a fallback floor. - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|---------|-------------|-------------|-----| -| AES-GCM encryption for mnemonic | Custom `javax.crypto.Cipher` wrapper | Existing `WalletManager.encrypt()/decrypt()` with Android Keystore key | Already implemented with StrongBox fallback and `setUnlockedDeviceRequired(true)`. | -| BIP39 wordlist | Custom wordlist | Embedded `WORD_LIST` in WalletManager.kt (English BIP39) | Already 2048-word list in place. | -| BIP32 HMAC-SHA512 derivation | Custom derivation | Existing `derivePrivateKey()` using BouncyCastle `HMac` + `SHA512Digest` | Already implemented and unit-tested indirectly via `RavencoinTxBuilderTest`. | -| Base58Check encode/decode | Custom implementation | Existing `base58Encode`/`base58Decode` in WalletManager + RavencoinPublicNode | Already implemented. Note: 2 copies exist (one in each file) — consolidate in passing. | -| ECDSA signature (secp256k1) | Custom ECDSA loop | Existing `signEcdsa()` in RavencoinTxBuilder via BouncyCastle `ECNamedCurveTable` | Already implemented with DER encoding and low-s normalization. | -| Coin selection algorithm | Custom Knapsack/BnB | **Hand-rolled greedy (existing)** — documented exception | [ASSUMED] The existing `sendRvnLocal` uses all available RVN UTXOs + old-address sweep because the D-17 quantum-resistance model requires consolidating to a single fresh address per tx. This is incompatible with Bitcoin Core's Branch-and-Bound (which optimizes for "leave small change"). The existing "use everything and cycle" is correct for this wallet model. Do NOT introduce a standard coin selector in this phase. | -| Subscription framing / reconnect | Custom socket manager | Standard "reader coroutine per socket" pattern (see Pattern 1) | The ElectrumX protocol is newline-delimited JSON — simple enough to hand-roll, and no library provides a Kotlin/Android client for Ravencoin ElectrumX. | -| Tx rebroadcast scheduler | Custom `ScheduledExecutorService` | WorkManager `OneTimeWorkRequest` with `setInitialDelay` | WorkManager survives process death, respects Doze, and already in the dependency tree. | -| Background periodic polling | AlarmManager + BroadcastReceiver | WorkManager `PeriodicWorkRequest` (already implemented in WalletPollingWorker) | Existing pattern. 15-min minimum is the system floor for periodic work. [CITED: developer.android.com/reference/kotlin/androidx/work/PeriodicWorkRequest] | -| BIP39 seed → HMAC integrity tag | Custom HMAC wrapper | BouncyCastle `HMac(SHA256Digest())` with a second Keystore-wrapped key | Standard "encrypt-then-MAC"; D-15 requires HMAC of seed alongside ciphertext. | -| Fee estimation target logic | Custom ratio math | `blockchain.estimatefee(6)` with fallback to `blockchain.relayfee` × 2 | ElectrumX already implements Bitcoin-Core-style fee estimation; we just consume it. | -| Ravencoin asset transfer tx bytes | Custom script builder | Existing `RavencoinTxBuilder.buildAndSignMultiAssetTransfer` + `buildAndSignMultiAddressSend` | 1627 lines of tested tx-building logic. Do not touch in this phase. | - -**Key insight:** The dangerous temptations in this phase are (a) "let me just add a second PeriodicWorkRequest with 5-min interval" — it won't run, the OS enforces 15-min minimum, and (b) "let me cache the mnemonic briefly in memory to avoid re-auth" — violates D-16 and the StrongBox threat model. Both are hard-rules from the OS and the user decisions, not preferences. - -## Runtime State Inventory - -> This is not a rename/refactor phase, but Phase 30 DOES introduce new persistent state (SQLite tables, notification channel, WorkManager jobs) that must be considered. Including this section for completeness. - -| Category | Items Found | Action Required | -|----------|-------------|------------------| -| Stored data | NEW: `wallet_state_cache`, `tx_history`, `reserved_utxos`, `pending_consolidations`, `quarantined_nodes` in a new `wallet_reliability.db`. Existing: `electrum_certificates.db` (TOFU from Phase 10), SharedPrefs `wallet_poll` (Phase 20 poll baseline), SharedPrefs `raventag_wallet` (mnemonic ciphertext). | CREATE TABLE IF NOT EXISTS on first open. No migration needed — all new. | -| Live service config | Phase 10 added `electrum_certificates.db` with pinned TOFU fingerprints. Phase 30 adds new tables, no migration. Existing Keystore alias `raventag_wallet_key` is unchanged. | None | -| OS-registered state | **NEW notification channel `incoming_tx`** (D-07), separate from existing `transaction_progress` (Phase 20). **NEW WorkManager work `raventag_rebroadcast`** (D-25, OneTime) and **extended `wallet_polling`** (D-06, existing periodic). | Channel must be created in Application.onCreate (API 26+ requirement). WorkManager name strings must avoid collision with Phase 20's `wallet_polling_worker`. | -| Secrets/env vars | None changed. Existing: `raventag_wallet.seed_enc`, `raventag_wallet.mnemonic_enc` in SharedPrefs. D-15 adds HMAC column but under the same SharedPrefs file; no new secret. | None — add new SharedPrefs keys `KEY_SEED_HMAC`, `KEY_MNEMONIC_HMAC` (still ciphertext, still Keystore-wrapped). | -| Build artifacts | None. All new code is pure Kotlin; no build-time artifacts (no proto files, no generated DB). | None | - -## Common Pitfalls - -### Pitfall 1: Scripthash Subscription Status Arrives BEFORE Subscribe Response - -**What goes wrong:** You call `blockchain.scripthash.subscribe` expecting a single RPC response, but ElectrumX may emit a notification on that same scripthash asynchronously before your response. The reader consumes the notification first and your `subscribe()` await times out. - -**Why it happens:** The protocol is inherently async on a shared socket. [CITED: electrumx.readthedocs.io/protocol-basics.html] The server doesn't distinguish outbound notifications from inbound responses — both are JSON objects on the same socket. - -**How to avoid:** Match responses by `id` (the integer you sent in the request), not by arrival order. Notifications do NOT have `id`; responses always do. Route `{id: ...}` lines to a response-table and `{method: "blockchain.scripthash.subscribe", params: [hash, status]}` lines to the event flow. - -**Warning signs:** Subscribe "timing out" sporadically; unit tests that pass but integration is flaky; `reader.readLine()` returning a notification when you expected a response. - -### Pitfall 2: TCP Connection Silently Dies on Mobile Networks - -**What goes wrong:** App foregrounded, subscription socket "open," but handset switched from WiFi to LTE 20 minutes ago. The socket is a zombie — writes fail, reads block forever. User sees "connected" but never receives push events. - -**Why it happens:** Mobile network transitions don't always send FIN; the old socket becomes undeliverable. Without TCP keepalive or app-level ping, the client doesn't know. [CITED: github.com/square/okhttp/issues/3042] - -**How to avoid:** (a) Set `sslSocket.keepAlive = true` AND (b) send a periodic `server.ping` (returns null) every 60s from the subscription coroutine. Reconnect on ping failure. (c) Consider registering a `ConnectivityManager.NetworkCallback` to proactively reset the subscription socket when the network changes. - -**Warning signs:** User reports "app says connected but doesn't see incoming tx" after leaving it open an hour. - -### Pitfall 3: `KeyPermanentlyInvalidatedException` Disguised as a Generic Crypto Error - -**What goes wrong:** Catching a broad `Exception` around `cipher.doFinal()` hides that the Keystore key was invalidated by biometric enrollment change. User sees a generic "failed to unlock wallet" message and assumes the app is broken. - -**Why it happens:** `KeyPermanentlyInvalidatedException` extends `InvalidKeyException`; a catch-all `Exception` handler absorbs it with no recovery path. [CITED: developer.android.com/reference/android/security/keystore/KeyPermanentlyInvalidatedException] - -**How to avoid:** Catch `KeyPermanentlyInvalidatedException` specifically. Route the user to the "Device security changed" dialog (D-15 copywriting contract, UI-SPEC.md line 186) with a single action: restore from recovery phrase. Do NOT silently regenerate the key — the existing ciphertext becomes garbage and funds are irrecoverable without the phrase. - -**Warning signs:** User enrolls a new fingerprint, opens the app, gets "something went wrong" with no path forward. - -### Pitfall 4: Stale Mempool Cache Masks a Successful Broadcast - -**What goes wrong:** User sends RVN, broadcast returns a txid, but the app's UI still shows the old balance for 2 minutes until the next 30s poll catches up. User thinks the send failed, retries, and now has two pending consolidations. - -**Why it happens:** The broadcast path writes the raw tx to the network but does not update the local cache. The subscription socket will eventually notify, but "eventually" is server-dependent. - -**How to avoid:** After successful broadcast, synchronously: (a) INSERT into `reserved_utxos` (D-20), (b) add an optimistic row to `tx_history` with height=0, (c) emit a state update so WalletScreen reflects the pending tx immediately. On next poll/subscription event, reconcile. - -**Warning signs:** User reports "I had to refresh 3 times before my transaction showed up." - -### Pitfall 5: Batched `getUtxosAndAllAssetUtxosBatch` Misses Asset UTXOs After Consolidation - -**What goes wrong:** Existing `getUtxosAndAllAssetUtxosBatch` filters asset UTXOs by `getAllAssetOutpoints`. If the set is stale (cached too long), a recent consolidation's new asset outputs are missed. - -**Why it happens:** [VERIFIED: RavencoinPublicNode.kt:658-740] The batch fetches RVN UTXOs, asset UTXOs, and the outpoint set from ElectrumX in parallel. If the outpoint set query fails, it falls back to empty — causing asset UTXOs to look like plain RVN UTXOs and vice versa. - -**How to avoid:** On any failure of the batch, invalidate the cache and force a full refetch on the next cycle. Do NOT display cached state after a batch failure — that's precisely the "stale indicator" path from D-12. - -### Pitfall 6: Reserved UTXO Leak on Crash - -**What goes wrong:** App submits a consolidation, INSERTs into `reserved_utxos`, then crashes before the SQLite WAL syncs. Reserved row persists, user thinks balance is permanently reduced. - -**Why it happens:** SQLite WAL is async-durable by default; a crash mid-write can leave partial state. - -**How to avoid:** (a) Open `reserved_utxos.db` with `PRAGMA synchronous=FULL` AND `PRAGMA journal_mode=WAL` — durability without too much perf hit. (b) On app startup, prune rows older than 48h — no consolidation takes longer than that to confirm. (c) Always reconcile: on WalletScreen open, fetch current mempool+confirmed history for the submitted txid; if found, delete the reservation. - -### Pitfall 7: BIP39 Checksum Validator Accepts Trailing Whitespace - -**What goes wrong:** User pastes a mnemonic from a password manager with a trailing newline. The existing `validateMnemonic()` splits on space, producing a blank 13th word. Some implementations silently drop blanks and accept the input — with a wrong derivation key. - -**Why it happens:** BIP39 is strict about word count (12/15/18/21/24) and checksum, but not every implementation normalizes input. - -**How to avoid:** `input.trim().split(Regex("\\s+"))` — collapse any whitespace. Reject anything not in {12, 15, 18, 21, 24}. Run the checksum on the normalized list. The existing `validateMnemonic()` at line 818 should be audited for this. - -### Pitfall 8: TLS Cert Rotation Breaks All Fallbacks Simultaneously - -**What goes wrong:** The admin of a public ElectrumX node rotates their TLS cert. Every app user hits a TOFU mismatch at once. Per D-11 they all quarantine for 1 hour, but if other nodes are also down, users see "Offline" and cannot send. - -**Why it happens:** TOFU security model is intentional: cert rotation IS a protocol-level notification that something changed. The app cannot distinguish rotation from MITM. - -**How to avoid:** (a) Hardcode enough fallbacks that a single rotation leaves others working (the current 3-node list from `RavencoinPublicNode.kt:172-177` is marginal; adding 2 more from `rvn4lyfe.com` server.json is recommended). (b) Surface the quarantine state in the connection-pill bottom-sheet (UI-SPEC §Connection pill) so power users can debug. (c) Document in release notes: "If multiple nodes are quarantined, clear TOFU pins in Settings → Advanced." (Deferred for a future phase; in Phase 30, quarantine is silent per D-11.) - -## Code Examples - -### Example 1: Persistent subscription reader with id-matched responses - -```kotlin -// Source: ElectrumX protocol docs (https://electrumx.readthedocs.io/en/latest/protocol-basics.html) -private class SubscriptionSession( - val host: String, - val socket: SSLSocket, -) { - private val writer = PrintWriter(socket.outputStream, true) - private val reader = BufferedReader(InputStreamReader(socket.inputStream)) - private val pending = ConcurrentHashMap>() - - suspend fun readLoop(events: MutableSharedFlow) { - while (coroutineContext.isActive) { - val line = withContext(Dispatchers.IO) { reader.readLine() } - ?: throw IOException("subscription socket closed by $host") - val obj = JsonParser.parseString(line).asJsonObject - if (obj.has("id")) { - val id = obj.get("id").asInt - pending.remove(id)?.complete(obj.get("result") ?: JsonNull.INSTANCE) - } else { - // Server-sent notification - val method = obj.get("method").asString - val params = obj.getAsJsonArray("params") - when (method) { - "blockchain.scripthash.subscribe" -> { - val scripthash = params.get(0).asString - val status = params.get(1).takeUnless { it.isJsonNull }?.asString - events.emit(ScripthashEvent.StatusChanged(scripthash, status)) - } - // blockchain.headers.subscribe, if we add it later - } - } - } - } - - suspend fun subscribe(scripthash: String): String?

For D-15 phase minimum (API 26), continue with the existing key spec without adding time-bounded auth. Biometric is invoked explicitly per reveal, not via timeout. -- `FingerprintManager` API — deprecated in API 28 in favor of `BiometricPrompt`. Existing code does not use `FingerprintManager`. Good. - -## Assumptions Log - -| # | Claim | Section | Risk if Wrong | -|---|-------|---------|---------------| -| A1 | `blockchain.estimatefee` returns RVN/kB float, not sat/vB | Fee Estimation / Pattern 5 | If the unit is different, fees will be off by ~100×. Mitigation: sanity-check the returned value against `blockchain.relayfee` — if estimatefee < relayfee, fall back to relayfee × 6 (target-6-block heuristic). | -| A2 | Ravencoin ElectrumX servers implement the subscription protocol identically to upstream kyuupichan ElectrumX | Architecture Pattern 1 | If asset-aware scripthash status computes differently, we may miss asset-transfer-only notifications. Mitigation: on any status change, refetch both RVN and asset UTXOs. | -| A3 | Public ElectrumX nodes (`rvn4lyfe.com`, `rvn-dashboard.com`, `162.19.153.65`, `51.222.139.25`) are still reachable in 2026 | Standard Stack / Node list | If all 4 are down, the wallet is unusable. Mitigation: add 1-2 more from community Discord or rvn4lyfe.com at plan time; also surface node status to UI (already D-12). | -| A4 | Android Keystore AES-GCM key created with `setInvalidatedByBiometricEnrollment` default behavior matches user expectations for D-15 | Pattern 2 | Existing `getOrCreateAndroidKey()` does NOT set `setInvalidatedByBiometricEnrollment` explicitly. Default is `true` when `setUserAuthenticationRequired(true)` is set, otherwise N/A. Since current spec does NOT set `setUserAuthenticationRequired(true)`, the key is NOT auto-invalidated on biometric change. This means `KeyPermanentlyInvalidatedException` will NOT fire on fingerprint enrollment — D-15's "detect keystore invalidation" path is only triggered by explicit key deletion (factory reset). Planner MUST decide: accept this (simpler, still secure for on-device only) OR add `setUserAuthenticationRequired(true) + setInvalidatedByBiometricEnrollment(true)` to the key spec (stronger, but regenerating the key permanently locks out existing wallets). Recommend documenting in plan-check. | -| A5 | 30-minute auto-rebroadcast interval (D-25) is not configurable by user | Pattern 4 / Rebroadcast Worker | User decision to keep "silent, no user-facing action" — implement with the fixed 30/60/120/240/480 min backoff documented. | -| A6 | `sum(utxo.value) - sum(reserved.value)` is always ≥ 0 | Pattern 3 / Example 2 | If a reservation outlives its underlying UTXO (e.g., reorg drops a tx), the subtraction can go negative. Example 2 uses `coerceAtLeast(0)`; plan should also cleanup stale reservations on startup. | -| A7 | WorkManager 15-min minimum is acceptable for D-06 background detection | D-06 | User explicitly chose 15 min in discussion-log. System enforces this minimum [CITED: developer.android.com]. No work-around that complies with Doze/power-save. | -| A8 | Ravencoin ElectrumX servers accept `blockchain.estimatefee(6)` (target = 6 blocks) | Fee Estimation | [VERIFIED: github.com/Electrum-RVN-SIG/electrumx-ravencoin/docs/protocol-methods.rst returns -1 if insufficient data]. Fallback to 0.01 RVN/kB handles this. | -| A9 | Bouncy Castle HMAC-SHA256 is sufficient for D-15 seed integrity check | D-15 | HMAC-SHA256 is standard; no reason to use anything else for this purpose. Key = second Keystore-wrapped AES-GCM key (or derived from the main key via HKDF for simplicity). | -| A10 | The existing `consolidate_fix.kt` scratch file at repo root (per STATE.md blockers) is NOT relevant to Phase 30 and can be deleted independently | Misc | STATE.md flags this as a blocker/concern but it's a repo-hygiene issue, not functionality. Plan should note: delete this file in a housekeeping task, separate from wallet-reliability scope. | - -## Open Questions - -1. **Should we harden `getOrCreateAndroidKey()` with `setUserAuthenticationRequired(true)` + `setInvalidatedByBiometricEnrollment(true)`? (A4 above)** - - What we know: Current spec does NOT require per-use authentication. All sends succeed silently if device is unlocked. - - What's unclear: CONTEXT.md D-15 says "require BiometricPrompt before revealing mnemonic words" — this is about the REVEAL flow, not every send. But also "detect KeyPermanentlyInvalidatedException on decrypt" — which would never fire with the current spec. - - Recommendation: **Use BiometricPrompt as a UI-level gate only for mnemonic reveal. Add HMAC-of-seed for integrity (D-15 third point). Do NOT change the Keystore key spec**; regenerating the key permanently breaks existing wallets, and the current spec's `setUnlockedDeviceRequired(true)` is already a reasonable bar. The KeyPermanentlyInvalidatedException handler becomes dead code only for a narrow reason (factory reset), and that's acceptable. - - Action for planner: confirm this interpretation. If user wants stricter (auth on every send), that's a larger migration and should be deferred. - -2. **What exactly goes in `tx_history.cycled_sat`?** - - What we know: D-19 says display "Sent 5 RVN · Cycled 244.9988 RVN · Fee 0.0012 RVN". The `cycled_sat` is the amount sent to the `changeAddress` (currentIndex+1) in the atomic tx. `RavencoinTxBuilder.buildAndSignMultiAddressSend` already emits this as an output. - - What's unclear: For pure RVN sends without asset sweep, this is just `totalIn - amountSat - feeSat`. For sends with asset sweep, RVN and assets both go to the same new address. - - Recommendation: `cycled_sat = sum(outputs where output.address == changeAddress)` regardless of whether it's RVN or asset value; assets reported separately in tx details. Planner to decide whether history row shows only RVN cycled or also counts asset outputs. - -3. **Should the subscription socket reconnect automatically on scripthash-status mismatch?** - - What we know: On network change, the old socket may die. D-12 says yellow pill = reconnecting, red = all nodes down. - - What's unclear: What triggers a reconnect? (Timeout? Explicit failure? Ping failure?) And what does "reconnect" mean for already-pinned TOFU fingerprints? - - Recommendation: Reconnect on (a) ping-timeout (60s without response), (b) read error, (c) connectivity change. TOFU pins persist (Phase 10 SQLite). If TOFU mismatch on reconnect → D-11 quarantine. - -4. **Current node list is 4 servers, but `rvn-dashboard.com` may not be SSL-enabled anymore.** - - What we know: Existing code has 4 servers. The rvn4lyfe.com servers.json only lists 3 (rvn4lyfe.com, an onion, 162.19.153.65). - - What's unclear: Which servers are actually healthy in 2026? - - Recommendation: In a plan-check step, runtime-verify each hardcoded server with a `server.version` call before shipping. If any fail, remove or replace. This is a "health check in CI" concern — the plan should add a one-shot connectivity test script. - -## Environment Availability - -Skipping this section — Phase 30 is pure Android code/config changes.

Implementation extends existing `ElectrumStatusBadge` by adding a YELLOW (degraded/reconnecting) state and the tap-to-open sheet: - -Tap behavior: opens a `ModalBottomSheet` with: -- Current node URL (monospace `bodySmall`) -- Last successful RPC timestamp (`RavenMuted bodySmall`) -- Fallback node list with per-node quarantine status (red dot if quarantined) -- Close button (`OutlinedButton` 1dp `RavenBorder`) - -### Tx history row, three-value outgoing (D-19) -Replaces the current single-amount outgoing display in `TxCard`. - -Layout (outgoing only; incoming row unchanged): -``` -[dot] [icon] [txid short] [amount col] - Sent -5 RVN - Cycled 244.9988 RVN - Fee 0.0012 RVN - 14/04/26 · 6/6 conf -``` -Spec: -- Row outer: existing `Card` with `RavenCard` bg, `RavenBorder` border, 12dp radius, padding 14dp/10dp. -- Left: existing status dot (10dp), existing direction icon (16dp `CallMade` in NotAuthenticRed). -- Middle: existing truncated txid in monospace, RavenMuted, `weight(1f)`. -- Right column: `Alignment.End`, gap `2dp` between the three value lines, `6dp` gap before timestamp row. - - Line 1 "Sent": `bodySmall` SemiBold, NotAuthenticRed, sign `-` prefix. - - Line 2 "Cycled": `labelSmall` Normal, AuthenticGreen. - - Line 3 "Fee": `labelSmall` Normal, RavenMuted. -- Decimal styling (10sp decimals) from existing pattern applies to all three values. -- Confirmations label uses existing `dotColor`: red 0, amber 1-5, green ≥6. - -Self-transfer (consolidation) row: single line `Cycled X RVN · Fee Y RVN`, icon `Icons.Default.Autorenew` in RavenOrange. No "Sent" line. - -### Pending balance line (D-24) -Rendered as a sibling of the main balance inside `BalanceCard`, directly under the fiat value: -- Row: 8dp gap, `Icons.Default.Schedule` 12dp RavenMuted, label "Pending", amount "+%.8f RVN" in amber `#F59E0B`, all `bodySmall`. -- Hidden entirely when mempool incoming is zero. - -### Reserved UTXO (D-20): no UI line -Reserved UTXOs are subtracted silently from spendable balance. NO visible "reserved" line; displayed spendable is already net. (Rationale: keeps the main balance the authoritative number and avoids leaking internal consolidation mechanics to users per D-17.) - -### Battery-saver chip (D-28) -Position: in the header column, below the connection pill and block-height row. -- Container: `RavenCard` -- Shape: `RoundedCornerShape(8.dp)` -- Border: `1dp 0xFFF59E0B` at 25% alpha -- Inner padding: `horizontal 8dp vertical 4dp` -- Icon: `Icons.Default.BatterySaver` 10dp, amber -- Label: "Battery saver · manual refresh" / "Risparmio energetico · aggiorna a mano" in `labelSmall` amber -- Only shown when `PowerManager.isPowerSaveMode() == true` AND the user is on WalletScreen foreground. - -### Mnemonic reveal biometric gate (D-15) -Before the 12/24-word grid becomes visible in `MnemonicBackupScreen`: -- Show a covering card: `RavenCard`, 16dp padding, `Icons.Default.Fingerprint` 24dp `RavenOrange`, body: "Authenticate to reveal the recovery phrase" (EN) / "Autenticati per mostrare la frase di recupero" (IT). -- CTA button: RavenOrange, `Reveal phrase` (EN) / `Mostra frase` (IT). -- On tap → `BiometricPrompt` with title "Authenticate" (EN) / "Autentica" (IT), negative button "Cancel" / "Annulla". -- On success → words grid becomes visible; covering card replaced. Copy-to-clipboard button remains enabled. -- On fail/cancel → card stays, no words displayed, short snackbar "Authentication canceled" (RavenMuted). - -### Restore-over-wallet confirm dialog (D-14) -New `AlertDialog` in `WalletScreen.kt` gated before `onRestoreWallet` is invoked when `walletBalance > 0 || assetsCount > 0`: -- Container: `Color(0xFF1A0000)` (same as existing delete dialog). -- Title: bold white, 18sp, "Replace current wallet?" (EN). -- Body: RavenMuted `bodyMedium` with interpolated balance + asset count. -- Forced backup step: if user has never seen MnemonicBackupScreen for current wallet, the body instead reads: "Back up your recovery phrase first. You can't undo this." and the **only** enabled button is `Back up phrase first` (RavenOrange) → routes to MnemonicBackupScreen. Cancel stays available. -- Once backup confirmed: normal dialog returns with both buttons (Replace NotAuthenticRed + Cancel outlined). - ---- - -## Loading UI Patterns (inherited from Phase 20, extended) - -### Sync-in-background indicator (new) -While periodic poll runs and cached state is already shown, display a **very subtle** indicator: a 2dp `LinearProgressIndicator` flush under the WalletScreen header, `RavenOrange` on `RavenBorder` track, indeterminate. Hidden as soon as refresh succeeds or fails. Do NOT show full-screen spinner during the periodic poll: only during initial restore (Phase 20 pattern). - -### Send/Transfer loading spinner -Unchanged from Phase 20 UI-SPEC § Loading UI Patterns. - -### Full-screen loading (initial wallet restore) -Unchanged from Phase 20 UI-SPEC § Loading UI Patterns. Still `40dp` RavenOrange `CircularProgressIndicator` centered. - -### Reconnecting toast -When all fallback nodes failed once and the app enters the 1h quarantine + retry loop (D-11), show **one** snackbar (not repeated): "Reconnecting to Ravencoin network…" / "Riconnessione alla rete Ravencoin…", RavenMuted background, no action button. - ---- - -## Interaction Contracts - -### WalletScreen refresh lifecycle (D-01, D-02, D-04, D-26) -1. User opens WalletScreen. -2. Cached state renders instantly from SQLite (balance, UTXOs, last 20 tx). -3. Cached-state banner appears (`History` icon + timestamp). -4. Sync-in-background linear indicator appears at header bottom edge. -5. Parallel fetch launches (balance + UTXOs + history + scripthash subscribe). -6. On success within 3s: cached banner and indicator dismiss; connection pill green. -7. On transient failure: cached banner switches to `Last updated … · reconnecting…`, pill yellow. -8. On all-nodes failure: pill red; Send/Receive buttons disabled (container alpha 0.3, RavenMuted text); offline empty-state card replaces content area if no cache exists. -9. When foreground + not power-save: periodic poll every 30s. -10. When power-save: poll paused (subscription stays open); battery-saver chip visible. - -### Receive flow (D-18) -1. User taps Receive. -2. ReceiveScreen opens showing `currentIndex` address and QR code (existing layout). -3. Label under QR: "Your current address" (EN) / "Il tuo indirizzo attuale" (IT). Sub-label: "Changes after your next send or consolidation." / "Cambia dopo il prossimo invio o consolidamento." -4. Tap the address text → copy + "Copied" checkmark fade (existing pattern). -5. No rotation button, no multi-address list (D-18). -6. If `currentIndex` advances while screen is open (auto-consolidation arriving), the address updates in place with a 200ms cross-fade. - -### Send flow (extends Phase 20 D-07) -1. User enters amount + address → taps Send. -2. Confirmation dialog appears with: amount, address, `Fee: %1 RVN · ~6 blocks` line. Editable fee icon (`Icons.Default.Edit`, RavenOrange) opens an inline `OutlinedTextField` accepting RVN/kB override. -3. If `estimatefee` returned null: warning line above the fee row in `RavenOrange bodySmall`: "Fee estimate unavailable. Using 0.01 RVN/kB fallback." / "Stima commissione non disponibile. Uso il valore minimo 0.01 RVN/kB." -4. User taps Send → button spinner → tx broadcast via `retryWithBackoff` → notification channel `transaction_progress` (Phase 20). -5. Consolidation outputs are constructed atomically (D-17): UI shows the tx in history using the three-value row (D-19). - -### Incoming tx detection (D-05, D-06, D-07) -1. App foreground: `blockchain.scripthash.subscribe` pushes notification → in-app snackbar (AuthenticGreen) + system notification (channel `incoming_tx`) + tx history prepended with status dot red (0 conf) + balance refresh. -2. App background: WorkManager 15-min poll (`NetworkType.CONNECTED`, no charging/idle constraint). If new tx detected, system notification only. -3. Tapping the system notification opens `TransactionDetailsScreen` with the txid. - -### Mnemonic export (D-13, D-15) -1. User taps "Reveal phrase" on WalletScreen. -2. Navigate to MnemonicBackupScreen. Biometric cover card is shown (never the words yet). -3. User taps "Reveal phrase" → BiometricPrompt. -4. On success → 12/24 word grid visible; Copy all + auto-erase-clipboard-after-60s pattern (existing). -5. On Keystore invalidation (`KeyPermanentlyInvalidatedException`) at any step: show critical error dialog "Device security changed" with single action `Restore from recovery phrase` → route to restore flow. - -### Mnemonic import / restore (D-14) -1. User taps Restore on WalletScreen setup card or overflow. -2. If current wallet has non-zero balance/assets AND has never completed backup: blocking dialog "Back up phrase first" (see Restore-over-wallet dialog above). -3. If current wallet has non-zero balance/assets AND has completed backup: standard replace-wallet confirm dialog. -4. If current wallet is empty: go straight to the 12-word restore input form (existing layout). -5. BIP39 checksum validation runs on every word change; invalid state shows `RavenOrange` outline on the offending word field + inline error above the grid: "Invalid recovery phrase. Check spelling and word order." -6. On tap Restore: button spinner → wallet restore → full-screen loading (Phase 20 pattern) → WalletScreen with fresh cache. - -### Tx details screen (D-19) -1. Tapping any tx card in history opens `TransactionDetailsScreen`. -2. Layout: txid (monospace, tap to copy), confirmations (existing), block height, timestamp, fee. -3. For outgoing txs: three labeled rows matching the summary card (Sent, Cycled, Fee), each with icon + amount + tap-to-copy address. -4. Button at bottom: `View on explorer` (RavenOrange outlined) opens an Intent to the configured explorer URL. - ---- - -## Implementation Notes - -### New notification channel (D-06, D-07) -Separate from the Phase 20 `transaction_progress` channel: - -| Property | Value | -|----------|-------| -| Channel ID | `incoming_tx` | -| Name (EN) | Incoming transactions | -| Name (IT) | Transazioni in arrivo | -| Description | Notifications for received RVN and assets | -| Importance | `IMPORTANCE_DEFAULT` (sound on, no vibration) | -| Show badge | true | -| Notification ID | 2100 base, incremented per txid hash | - -Tapping the notification opens `MainActivity` with action `VIEW_TRANSACTION` and extra `txid`. - -### SQLite-backed caches (D-04, D-20, D-23) -Not UI-visible, but UI relies on the presence of these tables: -- `wallet_state_cache(address, balance_sat, utxo_json, last_refreshed_at, tx_history_json)`: cache for instant render. -- `reserved_utxos(txid_in, vout, tx_submitted_at, PRIMARY KEY(txid_in, vout))`: per D-20. -- `tx_history(txid, ...)`: paged history (D-23). - -UI contract: balance shown = `sum(utxo.value) - sum(reserved.value)`. Pending line = `sum(mempool_incoming)` separately. - -### Disabled state for Send/Receive (D-12) -When all fallbacks are quarantined: -- Both buttons: container alpha 0.3, text color RavenMuted, icon RavenMuted. -- On tap: show Snackbar "Offline · all nodes unreachable" (NotAuthenticRedBg). No action. - -### Em-dash audit -Phase 30 introduces new Italian/English strings. Checker must grep the diff for the em dash character (U+2014) in: -- `AppStrings.kt` (stringsEn + stringsIt blocks added for this phase) -- Any new Compose `Text(...)` string literal -- Any new SnackbarHost message -- This UI-SPEC.md itself -If any em dash is found in new code, reject the plan; replace with `·`, `:`, or comma. - -### Accessibility -- All icons used as status indicators carry `contentDescription` (e.g. "Connection online", "Battery saver enabled", "Incoming transaction"). -- Touch targets on the connection pill: ≥48dp hit area even though visual is ~12dp tall (use `Modifier.size(width = max, height = 48.dp)` with aligned content). -- Mnemonic word grid: each word is announced with its index (1-12) for TalkBack: `contentDescription = "Word %1 of %2: %3"`. - ---- - -## Checker Sign-Off - -- [ ] Dimension 1 Copywriting: PASS -- [ ] Dimension 2 Visuals: PASS -- [ ] Dimension 3 Color: PASS -- [ ] Dimension 4 Typography: PASS -- [ ] Dimension 5 Spacing: PASS -- [ ] Dimension 6 Registry Safety: PASS (Android native, no registries) - -**Approval:** pending - ---- - -## Notes - -**Phase scope.** Phase 30 makes the existing wallet screens reliable under spotty connectivity, advancing quantum-resistance consolidation semantics, and mnemonic-handling safety. No brand-new top-level screens are added.

The warning type itself is computed by the ViewModel (Plan 02 Task 2) and received via the `warningType` parameter on IssueAssetScreen. - - B. Render `PreIssuanceWarning` in the screen body: place it between the form fields (asset name input, address input) and the submit button area.

Clicking opens `Intent(Intent.ACTION_VIEW, Uri.parse("${AppConfig.EXPLORER_URL}$issuedTxid"))`. Use `Modifier.clickable` with min 48dp height per accessibility requirements. - - - ConfirmationProgressRow: shows `confirmProgress` string with `%1$d/6 conferme` pattern. Icon: Icons.Default.Schedule 14dp amber for 0-5, Icons.Default.CheckCircle 14dp AuthenticGreen for 6. Text: bodySmall, amber for 0-5, AuthenticGreen for 6.

Fallback to raw error message for unknown errors. All messages defined in `AppStrings.kt` for localization across all 9 app languages. -- **D-02:** IPFS upload errors classified separately from RPC issuance errors. IPFS failures allow retry without restarting the entire form. -- **D-03:** Known error categories to classify: insufficient funds, duplicate asset name, RPC node unreachable/connection refused, RPC timeout, fee estimation failure, IPFS gateway down, IPFS auth expired, and invalid address format. - -### Pre-issuance Validation -- **D-04:** Full pre-flight validation in three sequential steps on submit: - 1. Wallet balance check: verify wallet has enough RVN for issuance fee (500/100/5 RVN per asset type) + estimated network fee. Show inline warning if insufficient. - 2. Asset name uniqueness check via backend API call. - 3. IPFS metadata upload. -- **D-05:** Multi-step progress indicator shown on submit button tap: "Caricamento IPFS..." → "Verifica disponibilita'..." → "Emissione in corso..." → "Conferma in corso...". Each step shows success/failure before advancing. -- **D-06:** IPFS upload triggered on submit (not as separate button, not auto on image select). Sequential steps with clear per-step status. Uploaded CID preserved for retry. - -### Issuance Retry Policy -- **D-07:** Auto-retry only safe errors with 5x exponential backoff (consistent with Phase 20 D-02/D-06). Safe errors: connection failures, DNS resolution failures, IPFS upload failures. These carry no double-spend risk since no tx was broadcast. -- **D-08:** On RPC timeout: do NOT re-broadcast. Instead query tx status via `getrawtransaction`. If tx landed on-chain → treat as success. If tx not found → prompt user to retry manually. This prevents accidental double-spend of the issuance fee. -- **D-09:** RPC rejections (duplicate asset name, insufficient funds, invalid parameters) → never auto-retry. Show classified error with suggested action (e.g., "Fondi insufficienti — invia RVN al wallet brand e riprova"). - -### Post-issuance Confirmation UX -- **D-10:** Show confirmation progress after successful issuance: "Pending..." → "N/6 conferme" → "Confermato". Consistent with Phase 30 D-08 receive confirmation pattern. Auto-dismiss banner after 6 confirmations. -- **D-11:** Txid in result banner is tappable. Opens block explorer at `https://ravencoin.network/tx/{txid}`. -- **D-12:** Issued asset appears in transaction history after next WalletScreen sync (Phase 30 D-01 periodic poll). -- **D-13:** Combined "Issue + Write Tag" flow: progress indicator includes NFC programming as distinct step: "Caricamento IPFS..." → "Emissione in corso..." → "Programmazione tag NFC..." → "Conferma (N/6)". Tag write step has its own progress since user must hold phone to tag. - -### Critical Constraints (non-negotiable) -- **C-01:** Unique token issuance flow (issue + NFC tag programming) must remain intact. All error handling changes are additive layers on top of the existing working flow. Do not restructure the `onIssueUniqueAndWriteTag` path. -- **C-02:** Asset emission currently works.

No classification, no actionable messaging, no retry. The `processIssueAndWrite` combined flow (lines 2233-2325) uses `Result.failure(Exception(...))` with hardcoded Italian strings but no classification. The `revokeAsset` callback (line 1714) discards the `AssetOperationResult` from `am.revokeAsset()` and always sets `issueSuccess = true`. - -The existing `RetryUtils.retryWithBackoff()` (Phase 20 pattern, 5 attempts, 1s base delay, 2x multiplier) can be reused for safe-error retries.

The `Resource.transientError`/`criticalError` pattern from Phase 20 can be used for error surfacing. - -**Primary recommendation:** Add error classification in the catch blocks of issuance callbacks and `processIssueAndWrite`, using exception message pattern-matching to select localized string keys.

Fix the `revokeAsset` result-discard bug. - - -## User Constraints (from CONTEXT.md) - -### Locked Decisions -- **D-01:** Classify known RPC errors into Italian user-facing messages. Fallback to raw error message for unknown errors. All messages defined in `AppStrings.kt` for localization across all 9 app languages. -- **D-02:** IPFS upload errors classified separately from RPC issuance errors. IPFS failures allow retry without restarting the entire form. -- **D-03:** Known error categories to classify: insufficient funds, duplicate asset name, RPC node unreachable/connection refused, RPC timeout, fee estimation failure, IPFS gateway down, IPFS auth expired, and invalid address format. -- **D-04:** Full pre-flight validation in three sequential steps on submit: (1) Wallet balance check, (2) Asset name uniqueness check via backend API call, (3) IPFS metadata upload. -- **D-05:** Multi-step progress indicator shown on submit button tap: "Caricamento IPFS..." to "Verifica disponibilita'..." to "Emissione in corso..." to "Conferma in corso...". Each step shows success/failure before advancing. -- **D-06:** IPFS upload triggered on submit (not as separate button, not auto on image select). Sequential steps with clear per-step status. Uploaded CID preserved for retry. -- **D-07:** Auto-retry only safe errors with 5x exponential backoff. Safe errors: connection failures, DNS resolution failures, IPFS upload failures. -- **D-08:** On RPC timeout: do NOT re-broadcast. Query tx status via `getrawtransaction`. If tx landed on-chain, treat as success. If not found, prompt user to retry manually. -- **D-09:** RPC rejections (duplicate name, insufficient funds, invalid params) never auto-retry. Show classified error with suggested action. -- **D-10:** Show confirmation progress after successful issuance: "Pending..." to "N/6 conferme" to "Confermato". Consistent with Phase 30 D-08 receive confirmation pattern. Auto-dismiss banner after 6 confirmations. -- **D-11:** Txid in result banner is tappable. Opens block explorer at `https://ravencoin.network/tx/{txid}`. -- **D-12:** Issued asset appears in transaction history after next WalletScreen sync (Phase 30 D-01 periodic poll). -- **D-13:** Combined "Issue + Write Tag" flow: progress indicator includes NFC programming as distinct step. Tag write step has its own progress since user must hold phone to tag. -- **C-01:** Unique token issuance flow must remain intact. All error handling changes are additive. -- **C-02:** Asset emission currently works. Do not alter successful issuance code path. -- **C-03:** IssueAssetScreen composable API (callback signatures) is the boundary. Error handling improvements happen in MainActivity callbacks and AssetManager. - -### Claude's Discretion -- Exact Italian error string content for each classification category -- IPFS retry UX details (inline retry button vs auto-retry within submit flow) -- Balance check threshold display format and minimum balance calculation -- Confirmation progress indicator visual design and animation -- Exact placement of progress step indicator in the IssueAssetScreen layout - -### Deferred Ideas (OUT OF SCOPE) -- Burn on-chain in revocation flow -- Asset transfer UX (TRANSFER_ROOT, TRANSFER_SUB modes) -- Notification on confirmation (background tracking + push) -- Em-dash cleanup in RavencoinTxBuilder.kt:907,908 - - -## Architectural Responsibility Map - -| Capability | Primary Tier | Secondary Tier | Rationale | -|------------|-------------|----------------|-----------| -| Error classification | ViewModel (MainActivity) | AssetManager | MainActivity catch blocks classify exceptions; AssetManager returns typed `AssetOperationResult` | -| User-facing error messages | AppStrings.kt | IssueAssetScreen (composable) | Strings are localized in AppStrings, displayed via resultMessage parameter | -| Pre-issuance validation | ViewModel (MainActivity) | AssetManager | Balance check uses walletInfo; uniqueness check uses AssetManager API call | -| Multi-step progress indicator | IssueAssetScreen (composable) | — | New composable component driven by sealed class from ViewModel | -| Retry policy | ViewModel (MainActivity) | RetryUtils | retryWithBackoff wraps the issuance call; classification decides auto vs manual | -| Confirmation progress | ViewModel (MainActivity) | RavencoinPublicNode | Poll `blockchain.transaction.get` for confirmations after successful txid | -| Combined Issue+Write flow | processIssueAndWrite (MainActivity) | Ntag424Configurator | Existing 7-step flow; add step progress and error classification | -| Revoke bug fix | revokeAsset (MainActivity) | — | Capture AssetOperationResult return value instead of discarding it | - -## Standard Stack - -### Core -| Library | Version | Purpose | Why Standard | -|---------|---------|---------|--------------| -| Jetpack Compose | BOM 2024.02+ | Multi-step progress indicator composable | Existing UI framework | -| kotlinx.coroutines | 1.7+ | `viewModelScope.launch`, `withContext(Dispatchers.IO)` | Existing async pattern | -| `RetryUtils.retryWithBackoff()` | Phase 20 | 5x exponential backoff for safe errors | Existing utility, proven in FeeEstimator and ElectrumX calls | - -### Supporting -| Library | Version | Purpose | When to Use | -|---------|---------|---------|-------------| -| `AssetOperationResult` | internal | Typed result envelope from AssetManager | All issuance callbacks already use this | -| `isTransientError()` | RetryUtils | Classify SocketTimeout/UnknownHost/IOExceptions | Auto-retry decision for safe errors | -| `TransactionNotificationHelper` | Phase 30 | Notification channel for confirmation tracking | Phase 30 created this pattern, reuse confirm pattern | - -### Alternatives Considered -| Instead of | Could Use | Tradeoff | -|------------|-----------|----------| -| Exception message parsing | Custom exception types | Custom types need new files; message parsing works with existing `catch(e: Throwable)` without restructuring | -| Sealed class for steps | Boolean `isLoading` | Current single bool cannot express multi-step; sealed class is the standard Compose pattern | -| ViewModel step state | Local composable state | The step state must survive recomposition and be set from async callbacks; ViewModel state is the right level | - -**Installation:** No new dependencies.

All error handling goes in the ViewModel callbacks. -- **Modifying successful code path:** C-02. Changes are additive try/catch wrappers, not restructuring. -- **Re-broadcasting on timeout:** D-08. Use `blockchain.transaction.get` to check if tx landed. Never re-broadcast blindly. -- **Hand-rolling IPFS retry:** Use `RetryUtils.retryWithBackoff` consistently. - -## Don't Hand-Roll - -| Problem | Don't Build | Use Instead | Why | -|---------|-------------|-------------|-----| -| Exponential backoff retry | Custom loop with Thread.sleep | `RetryUtils.retryWithBackoff()` | Existing, tested in FeeEstimator and ElectrumX calls, handles transient classification | -| Result envelope | Custom success/error wrapper | `AssetOperationResult` | Already used by all AssetManager methods | -| Confirmation progress notification | Custom notification lifecycle | `TransactionNotificationHelper` | Phase 30 pattern, proven for send flow | -| Error surfacing to UI | Custom dialog logic | `reportAsyncError()` (transientError/criticalError) | Phase 20 pattern, handles auto-dismiss and modal variants | - -**Key insight:** The project already has battle-tested patterns for retry, error surfacing, and confirmation tracking. Phase 40 implementation should reuse these patterns rather than creating new infrastructure. - -## Runtime State Inventory - -> This phase is an additive UX improvement -- no rename, refactor, or migration. Skip. - -## Common Pitfalls - -### Pitfall 1: Silent error in revokeAsset (pre-existing bug) -**What goes wrong:** `revokeAsset` at MainActivity.kt line 1714-1729 calls `am.revokeAsset(...)` but discards the returned `AssetOperationResult` and unconditionally sets `issueSuccess = true`. Result: revocations that fail at the backend level (e.g., auth error, asset not found) appear as successful to the user. -**Root cause:** The `withContext(Dispatchers.IO)` block returns the `AssetOperationResult` but the result is never captured. -**How to avoid:** Capture the result: `val result = withContext(Dispatchers.IO) { am.revokeAsset(BurnParams(...)) }` then check `result.success`. -**Warning signs:** Assets that remain unrevoked after UI shows "revocato". - -### Pitfall 2: Over-classification of error messages -**What goes wrong:** Exception messages from different sources (ElectrumX, WalletManager, RavencoinTxBuilder, AssetManager) are unreliable for pattern matching. Messages may change when ElectrumX server software is updated or when Ravencoin Core changes. -**Why it happens:** The project uses exception message string matching (e.g., `msg.contains("insufficient funds")`) rather than typed exception classes. -**How to avoid:** Keep classification as a single `when` block with fallback to raw message. Log the original message for debugging. Accept that some errors will fall through to the default case. -**Warning signs:** New ElectrumX versions causing misclassified errors. - -### Pitfall 3: Race condition in multi-step state -**What goes wrong:** If the user dismisses the screen or navigates away while a step is in progress, the coroutine continues running and may update stale state. -**Why it happens:** `viewModelScope.launch` is not cancelled on navigation; IssueStep state lives in the ViewModel. -**How to avoid:** Use `clearIssueResult()` existing pattern to reset step state on navigation. Check `isActive` at each step boundary. -**Warning signs:** "Ghost" step progress shown after returning to the screen. - -### Pitfall 4: Double submission during multi-step flow -**What goes wrong:** The user taps Submit during Step 1 (IPFS upload), and the step takes long enough that the user taps Submit again. -**Why it happens:** The step indicator replaces the submit button, but if button enablement is not properly gated, re-taps can occur. -**How to avoid:** Gate the submit button on `issueStep is IssueStep.Idle`. Once any step is in progress, the button must be disabled. The `isLoading` parameter already does this, but the step state must also gate it. -**Warning signs:** Multiple simultaneous IPFS uploads or issuance RPC calls. - -### Pitfall 5: Polling for confirmation after processIssueAndWrite -**What goes wrong:** The `processIssueAndWrite` flow is a `suspend` function that returns `Result`. The confirmation polling needs to run after the combined flow completes, but `onTagTapped` only sets `writeTagStep = SUCCESS` or `ERROR`. -**Why it happens:** The post-issuance confirmation phase is not part of the existing flow; it's additive. -**How to avoid:** After `processIssueAndWrite` returns success, start a separate coroutine for confirmation polling. Do not integrate it into the processIssueAndWrite function itself. -**Warning signs:** Confirmation progress never appears after combined flow. - -## Code Examples - -### Current revokeAsset bug (must fix) -```kotlin -// MainActivity.kt lines 1714-1729 -fun revokeAsset(assetName: String, reason: String, adminKey: String) { - val am = AssetManager(context = getApplication(), adminKeyStorage = adminKeyStorage!!) - viewModelScope.launch { - issueLoading = true - try { - withContext(Dispatchers.IO) { - am.revokeAsset(BurnParams(assetName, reason = reason, burnOnChain = false)) - } - issueSuccess = true // BUG: always true - issueResult = "Asset $assetName revocato" - } catch (e: Throwable) { - issueSuccess = false; issueResult = e.message ?: "Revoca fallita" - } finally { issueLoading = false } - } -} -``` - -### Current generic catch pattern in issuance callbacks -```kotlin -// MainActivity.kt line 1625-1627 (issueRootAsset example) -try { - val txid = withContext(Dispatchers.IO) { - wm.issueAssetLocal(assetName, qty.toDouble(), toAddress, units = 0, reissuable = reissuable, ipfsHash = ipfsHash) - } - issueSuccess = true - issueResult = s.issueRootSuccess.replace("%1", assetName).replace("%2", "${txid.take(16)}...") -} catch (e: Throwable) { - issueSuccess = false; issueResult = getStrings().issueFailed // Generic, no classification -} -``` - -### Existing retryWithBackoff usage pattern -Source: `android/app/src/main/java/io/raventag/app/utils/RetryUtils.kt` -```kotlin -RetryUtils.retryWithBackoff(maxAttempts = 5, initialDelayMs = 1000L, backoffMultiplier = 2.0) { - networkCall() // Will retry on SocketTimeout, UnknownHost, transient IOException -} -``` - -### Existing isTransientError classification -Source: `android/app/src/main/java/io/raventag/app/utils/RetryUtils.kt` -```kotlin -fun isTransientError(e: Exception): Boolean = when (e) { - is SocketTimeoutException -> true - is UnknownHostException -> true - is IOException -> { - val msg = e.message?.lowercase() ?: return false - msg.contains("timeout") || msg.contains("connection") || msg.contains("network") || msg.contains("temporary") - } - else -> false -} -``` - -### Burn fee constants for balance check -Source: `android/app/src/main/java/io/raventag/app/wallet/RavencoinTxBuilder.kt` -```kotlin -const val BURN_ROOT_SAT = 50_000_000_000L // 500 RVN -const val BURN_SUB_SAT = 10_000_000_000L // 100 RVN -const val BURN_UNIQUE_SAT = 500_000_000L // 5 RVN -``` - -## State of the Art - -| Old Approach | Current Approach | When Changed | Impact | -|--------------|------------------|--------------|--------| -| Generic `issueFailed` string | Classified error with specific message + action | Phase 40 | Users get actionable guidance instead of "emissione fallita" | -| Single `isLoading` boolean | Multi-step sealed class with per-step status | Phase 40 | Users see which step failed and can act on it | -| No retry on issuance failure | Safe-error retry with 5x exp backoff + timeout check | Phase 40 | Transient failures auto-recover without user action | -| `revokeAsset` always succeeds | `revokeAsset` checks AssetOperationResult | Phase 40 | Silent revocation failures surface to user | - -**Deprecated/outdated:** -- `revokeAsset` result discard (MainActivity.kt line 1721): confirmed bug via code review; fix is in scope since it's a silent failure elimination - -## Assumptions Log - -| # | Claim | Section | Risk if Wrong | -|---|-------|---------|---------------| -| A1 | Exception message string matching is reliable enough for the 8 known categories | Standard Stack | ElectrumX/Ravencoin error messages vary by version; misclassification falls back to raw message which is acceptable | -| A2 | Backend does not have a dedicated name-uniqueness API endpoint | Pre-issuance Validation | Pre-issuance validation must use ownedAssets list from frontend cache. If backend endpoint exists, use it instead | -| A3 | `RavencoinPublicNode.callElectrumRawOrNull(method, params)` can query `blockchain.transaction.get` for timeout-check | Confirmation Tracking | If `callElectrumRawOrNull` cannot reach any server, timeout handling degrades to "assume failure, prompt retry" which is the D-08 fallback | -| A4 | The `walletInfo.balanceRvn` value is current enough for pre-issuance balance check | Pre-issuance Validation | If wallet balance is stale (not refreshed), the check may pass when on-chain balance is insufficient. The `issueAssetLocal()` will fail with its own error. This is acceptable as a best-effort pre-check | - -## Open Questions (RESOLVED) - -1. **Backend name uniqueness endpoint?** - - What we know: `AssetManager` has `issueAsset`/`issueSubAsset`/`issueUniqueToken` but no dedicated "check name exists" endpoint. The ownedAssets list in the frontend cache is the closest proxy. - - What's unclear: Whether the backend provides an endpoint like `/api/brand/check-name` or if we should just check against the local cache. - - RESOLVED: Use local ownedAssets list for pre-flight check (ownedAssets contains all brand assets). Consider adding a backend endpoint in Phase 50 if needed. - -2. **Exact error strings from WalletManager.issueAssetLocal()?** - - What we know: Uses `error("...")` (IllegalStateException), `require(...)` (IllegalArgumentException), and exceptions from RavencoinTxBuilder and RavencoinPublicNode. - - What's unclear: The full set of possible error messages without running the code against all failure modes. - - RESOLVED: Use broad message pattern matching (.contains) in the classification function. Add logging (`Log.e`) of the original message for debugging. Fall through to raw message for unclassified errors. - -3. **getrawtransaction availability?** - - What we know: `RavencoinPublicNode` uses ElectrumX protocol, which provides `blockchain.transaction.get`. This is available via `callElectrumRawOrNull`. - - What's unclear: Whether the verbose=true format returns a `height` field for all tx states (mempool vs confirmed). - - RESOLVED: In timeout handling, check if `blockchain.transaction.get` returns a result. If height > 0, tx is confirmed. If height == null or result is error, tx not found. - -## Validation Architecture - -### Test Framework -| Property | Value | -|----------|-------| -| Framework | JUnit 4 + Robolectric (Android project) | -| Config file | Not checked -- Phase 30 used @Ignore for Robolectric-dependent tests | -| Quick run command | `./gradlew :app:testDebugUnitTest -x lint` | -| Full suite command | `./gradlew :app:testDebugUnitTest` | - -### Phase Requirements to Test Map -| Req ID | Behavior | Test Type | Automated Command | File Exists? | -|--------|----------|-----------|-------------------|-------------| -| D-01 | Error classification maps known exception messages to correct string keys | unit | `./gradlew :app:testDebugUnitTest --tests "*IssueErrorClassificationTest*"` | Will be Wave 0 | -| D-07 | retryWithBackoff wraps transient errors correctly | unit | Reuse existing RetryUtils tests | Existing tests | -| D-10 | Confirmation polling logic | unit | `./gradlew :app:testDebugUnitTest --tests "*ConfirmationTest*"` | Wave 0 | - -### Sampling Rate -- **Per task commit:** Not applicable (no existing test pattern for per-commit runs observed) -- **Per wave merge:** `./gradlew :app:testDebugUnitTest` -- **Phase gate:** Full test suite green before verify - -### Wave 0 Gaps -- [ ] `IssueErrorClassificationTest.kt` -- unit tests for `classifyIssuanceError` function (pure logic, no Android deps) -- [ ] `ConfirmationPollingTest.kt` -- unit tests for confirmation tracking logic (pure logic) -- [ ] No UI test detected for the composable step indicator (Jetpack Compose UI tests may need Compose Test dependency -- skip for Phase 40, manual verification only) - -## Environment Availability - -| Dependency | Required By | Available | Version | Fallback | -|------------|------------|-----------|---------|----------| -| Android SDK 34 | Compile target | ✓ | 34 | — | -| Kotlin 1.9 | Language | ✓ | 1.9.x | — | -| Gradle | Build system | ✓ | 8.x | — | -| OkHttp | HTTP client | ✓ | 4.x | — | -| Bouncy Castle | Crypto | ✓ | 1.77 | — | -| ElectrumX server | Broadcast/confirmation check | Runtime | — | Fallback server list, fail-closed | - -**Missing dependencies with no fallback:** None -- all dependencies are already in the project. - -## Sources - -### Primary (HIGH confidence) -- Codebase inspection of `MainActivity.kt`, `IssueAssetScreen.kt`, `AssetManager.kt`, `WalletManager.kt`, `AppStrings.kt`, `RetryUtils.kt`, `RavencoinPublicNode.kt`, `RavencoinTxBuilder.kt`, `TransactionNotificationHelper.kt` - -### Secondary (MEDIUM confidence) -- `40-CONTEXT.md` — Phase decisions and constraints (D-01 through D-13, C-01 through C-03) -- `.planning/STATE.md` — Project progress and recent decisions -- `.planning/PROJECT.md` — Milestone focus and requirements - -## Metadata - -**Confidence breakdown:** -- Standard stack: HIGH - All patterns and libraries verified in codebase -- Architecture: HIGH - Existing flows well understood, changes are additive -- Pitfalls: HIGH - revokeAsset bug confirmed via code read, other patterns observed in existing code - -**Research date:** 2026-04-25 -**Valid until:** 2026-05-25 (codebase is stable, no expected breaking changes) diff --git a/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md b/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md deleted file mode 100644 index e811eba..0000000 --- a/.planning/phases/40-asset-emission-ux/40-UI-SPEC.md +++ /dev/null @@ -1,597 +0,0 @@ ---- -phase: 40 -slug: asset-emission-ux -status: draft -shadcn_initialized: false -preset: none -created: 2026-04-25 ---- - -# Phase 40: UI Design Contract - -> Visual and interaction contract for Phase 40 Asset Emission UX.

No third-party block vetting required. - ---- - -## Key Visual Patterns (Phase 40 specific) - -### Pattern 1: Multi-Step Progress Indicator - -**Purpose:** Replaces the simple `isLoading` boolean-driven spinner with a per-step visual timeline showing the user exactly where in the issuance flow they are and which step succeeded or failed. - -**Location:** Between the form fields area and the submit button in `IssueAssetScreen.kt`. The progress indicator replaces the submit button entirely while steps are running. When no step is active (Idle), neither the indicator nor the submit button is affected. - -**Layout specification:** -``` -+------------------------------------------+ -| | -| [Step 1] [Caricamento IPFS...] | Completed: green check + muted text -| | -| | | Vertical connector line, 2dp wide, RavenBorder -| | -| [Step 2] [Verifica disponibilita'] | Current: Orange spinner + orange bold text -| | -| | | -| | -| [Step 3] [Verifica nome...] | Pending: hollow circle + muted text -| | -| | | -| | -| [Step 4] [Emissione in corso...] | Pending (shown based on flow stage) -| | -+------------------------------------------+ -``` - -**Step row specification:** -- Outer container: `Row` with `Modifier.fillMaxWidth()`, vertical center alignment. -- Left icon column: fixed 28dp width, `Arrangement.Center` vertically. Icon size: 20dp. - - Pending: `Box` with 8dp circle hole (`RavenBorder`, 2dp `BorderStroke`), no fill. - - In progress: `CircularProgressIndicator` 20dp, 2dp stroke, `RavenOrange`. - - Completed: `Icons.Default.CheckCircle` 20dp, `AuthenticGreen`. - - Failed: `Icons.Default.Error` 20dp, `NotAuthenticRed`. -- Right label column: `Column`, `weight(1f)`, padding start 8dp. - - Step name text: `bodySmall` (14sp Normal), color depends on state (see Color section). - - Failed state shows error message as second line: `labelSmall` (12sp), `NotAuthenticRed`, below step name with 2dp gap. -- Vertical connector line: `Box` with `Modifier.width(2.dp).height(12dp).background(RavenBorder)`, positioned between step rows, aligned to the center of the icon column. Only shown between non-terminal steps. - -**Step row vertical gap:** 12dp between rows, plus 12dp after the connector. - -**When to show:** The indicator is shown only while `issueStep` is not `Idle`. It replaces the `SubmitButton` composable during active steps. After the flow completes (success or failure), the indicator is replaced by the result banner (existing pattern). The user cannot submit again until they navigate away and come back (or the `clearIssueResult()` pattern clears the state). - -**Animation:** -- Current step icon: the `CircularProgressIndicator` provides its own indeterminate animation (existing Material 3 behavior). -- Step transitions: no animation between step state changes beyond the icon swap. Immediate visual update is preferred over animated transitions per the "responsive feedback" requirement. - -**Detailed logic for step display:** -- The indicator shows ALL steps that will be executed in the current flow, not just the remaining ones. Completed steps remain visible with green checkmarks so the user can see overall progress. -- The combined "Issue + Write Tag" flow shows the `NFC_PROGRAMMING` step between `ISSUING` and `CONFIRMING`. The standalone issuance flow skips this step. -- The `BALANCE_CHECK` and `NAME_CHECK` steps are shown as a single row "Verifica disponibilita'..." (combined label) since they run sequentially and fast. The inner progress distinguishes them but the UI shows one row. - -### Pattern 2: Error Classification Banner (extending result banner) - -**Purpose:** Shows the classified error message (from Research Pattern 1) in the existing result banner at `IssueAssetScreen.kt:256-269`, with added suggested action text. - -**Extends existing pattern:** -The existing result banner (lines 256-269) is a `Card` with `AuthenticGreenBg` or `NotAuthenticRedBg`, icon, and single-line message. Phase 40 extends this: - -- Error state: two-line text inside the banner (primary error message + suggested action on second line). -- Both lines use `bodySmall` (14sp Normal). Primary line: `NotAuthenticRed`. Suggestion line: `RavenMuted` (to de-emphasize the action text vs the error). -- For IPFS errors, the suggestion line is replaced by a "Riprova" (Retry) inline button: `TextButton` with `RavenOrange` text, `contentPadding = PaddingValues(horizontal = 8.dp, vertical = 2.dp)`, no background. Positioned to the right of the error text or as a separate row below. -- For timeout errors, the suggestion line includes the txid (if known) with "Verifica su explorer" link. - -**Txid tappable link (D-11):** -When the result banner shows a successful issuance with a txid, the txid text in the banner must be tappable: -- Txid displayed in `FontFamily.Monospace`, `bodySmall`, `AuthenticGreen`. -- Clickable area: the txid text only (not the entire banner). -- On tap: open `Intent(Intent.ACTION_VIEW, Uri.parse("https://ravencoin.network/tx/{txid}"))`. -- Visual indicator: underline on the txid portion, `clickable` modifier, no color change (stay AuthenticGreen). -- If no txid is available (e.g., error state), no clickable element. - -### Pattern 3: Pre-Issuance Validation Warning (inline) - -**Purpose:** Shows inline warning below the form fields when pre-submit validation detects a condition that will cause issuance failure. Displayed BEFORE the user taps submit (as opposed to error classification which is post-submit). - -**Location:** Between the form fields and the submit button. Same position as the result banner. - -**Behavior:** -- Balance check: shown when the user has entered form fields but wallet balance is below the required threshold. NOT shown while fields are empty. -- Name uniqueness check: shown when the typed asset name already exists in `ownedAssets`. Re-evaluated on every keystroke to the asset name field. - -**Display specification:** -- Container: `RavenCard` background, `RoundedCornerShape(12.dp)`. -- Border: 1dp amber `0xFFF59E0B.copy(alpha = 0.4f)`. -- Inner padding: 12dp. -- Icon: `Icons.Default.Warning` 16dp, amber `0xFFF59E0B`. -- Text: `bodySmall` (14sp Normal), amber `0xFFF59E0B`, single line or two lines. -- Margin below the warning: 12dp (gap before submit button). -- The warning is auto-dismissed when the condition is resolved (balance topped up, name changed). -- Only one warning shown at a time (balance check takes priority over name check). - -### Pattern 4: Confirmation Progress (N/6) - -**Purpose:** After successful issuance (txid known), show the confirmation counter in the result banner area while the ViewModel polls for confirmations (D-10). - -**Location:** The existing result banner position (`IssueAssetScreen.kt:256-269`). The success result banner remains visible, and the confirmation status is shown as an additional row beneath the success message. - -**Display specification:** -``` -+------------------------------------------+ -| Check Token OUTFIT/BAG02#SN0001 emesso | Success message (existing) -| | -| Schedule Conferma (3/6) | New confirmation row -+------------------------------------------+ -``` - -- Confirmation row: padding start 36dp (aligned to text start after the 20dp icon), `bodySmall` (14sp Normal). -- Icon: `Icons.Default.Schedule` 14dp, amber `0xFFF59E0B` for 0-5 confirmations; `Icons.Default.CheckCircle` 14dp, `AuthenticGreen` for 6/6. -- Text format: `"Conferma (N/6)"` in `bodySmall`. Color: amber for 0-5, `AuthenticGreen` for 6/6. -- Auto-dismiss (D-10): when 6/6 is reached, the entire result banner + confirmation row fades out (animate to alpha 0 over 500ms, then the parent composable hides via `resultSuccess = null`). This is the only animated transition in Phase 40. -- Polling interval: 30 seconds (as specified in Research Pattern 4). -- The confirmation progress only appears on the IssueAssetScreen. The user can navigate away and the confirmation continues in the background via `viewModelScope.launch`. - -### Pattern 5: Button Combined Flow Progress (D-13) - -**Purpose:** The combined "Issue + Write Tag" flow (`processIssueAndWrite` in MainActivity.kt) has its own 7-step internal flow. The multi-step progress indicator adapts to show these steps. - -**Layout:** Same vertical timeline as Pattern 1, but with `NFC_PROGRAMMING` step injected between `ISSUING` and `CONFIRMING`: - -1. `IPFS_UPLOAD` -- "Caricamento IPFS..." -2. `BALANCE_CHECK` -- "Verifica disponibilita'..." -3. `NAME_CHECK` -- "Verifica nome..." -4. `ISSUING` -- "Emissione in corso..." -5. `NFC_PROGRAMMING` -- "Programmazione tag NFC..." (unique to combined flow) -6. `CONFIRMING` -- "Conferma (N/6)" - -The `NFC_PROGRAMMING` step shows the same waiting/progress state as the existing `WriteTagScreen.kt` `PROCESSING` step but displayed inline in the step indicator rather than on a separate screen. This replaces the separate `WriteTagScreen` navigation for the combined flow; the user stays on `IssueAssetScreen` throughout. - -**NFC tap waiting state within progress indicator:** -When `NFC_PROGRAMMING` becomes the active step, the indicator row switches to a special state: -- Icon: `Icons.Default.NearMe` 20dp, `RavenOrange`, with an infinite scale animation (0.92 to 1.08, 900ms, FastOutSlowInEasing, RepeatMode.Reverse) -- matching the existing `NfcWaitStep` pattern from `WriteTagScreen.kt:167-176`. -- Label: "Avvicina il tag NFC al telefono" in `bodySmall`, `RavenOrange`. -- Subtitle: "Tieni il telefono vicino fino al termine." in `labelSmall`, `RavenMuted`. -- This state persists until the NFC tag is detected or the user cancels. - ---- - -## Loading UI Patterns (inherited from Phase 20/30, extended) - -### Button Loading Spinner -Unchanged from Phase 20 UI-SPEC: 20.dp white `CircularProgressIndicator`, 2.dp stroke, disabled button at 30% opacity. Still used for the submit button before the multi-step progress indicator activates. Once the multi-step indicator is shown, the button is replaced entirely. - -### Multi-Step Indicator Spinner -Each step's in-progress state uses a 20.dp `CircularProgressIndicator`, 2.dp stroke, `RavenOrange`. This is the same spinner as the button loading spinner, just relocated to the step icon column. - -### Full-screen loading -Not used in Phase 40. The issuance flow is interactive enough that a full-screen overlay would block the user from seeing step progress. - -### Confirmation polling progress -Indeterminate: no linear progress bar. The confirmation row shows `N/6` counter as the primary progress communication (Pattern 4 above). - -### IPFS retry -When IPFS upload fails during the multi-step flow (D-02): -- The `IPFS_UPLOAD` step shows a red X and the error message. -- Below the step label, a "Riprova" (Retry) inline `TextButton` appears: `RavenOrange` text, no border, no background, 8dp padding. -- Tapping retry re-executes only the IPFS upload (not the entire pre-flight sequence). The previously uploaded CID is NOT discarded; the retry uses the same metadata. -- After 3 consecutive IPFS failures, the retry button is replaced with "Vai a Impostazioni" (Go to Settings) that opens the Settings screen to check IPFS credentials. -- This differs from auto-retry (D-07) which happens silently in the background for transient network errors. The inline retry button is for non-transient IPFS failures (auth expired, gateway down). - ---- - -## Interaction Contracts - -### Standard Issuance Flow - -**Pre-conditions:** -- User has filled out the form fields for the selected mode (ROOT, SUB, UNIQUE_TOKEN, REVOKE, UNREVOKE). -- Admin key is configured in Settings (for issue/revoke operations). -- Wallet exists and has been restored. - -**Interaction sequence:** -1. User fills form fields and optionally uploads an image via `ImagePickerButton`. -2. Real-time pre-issuance validation checks run on field input (balance check debounced 500ms after last change, name check on every keystroke). Warnings appear inline if conditions are met. -3. User taps the submit button (`btnIssueRoot`, `btnIssueSub`, `btnIssueUnique`, `btnIssueAndWrite`, `btnRevoke`, `btnUnrevoke`). -4. The submit button text is replaced by the multi-step progress indicator (Pattern 1). -5. Step 1 -- `IPFS_UPLOAD`: If an image is attached, metadata is uploaded to IPFS. Green checkmark on success; red X + "Riprova" on failure. -6. Step 2 -- `BALANCE_CHECK`: Wallet balance is checked against burn fee + network fee. Amber warning shown if insufficient. If insufficient, the step shows failure but the user can still proceed (the on-chain RPC will fail with its own classified error). -7. Step 3 -- `NAME_CHECK`: Asset name uniqueness checked against `ownedAssets`. Amber warning if duplicate name exists. If duplicate, the step shows failure; user must change the name. -8. Step 4 -- `ISSUING`: RPC issuance is broadcast via `WalletManager.issueAssetLocal()`. On success: green checkmark, txid captured. On failure: classified error message (Pattern 2) with suggested action. Safe errors auto-retry via `retryWithBackoff` (D-07); non-transient errors show the classification banner. -9. Step 5 -- `CONFIRMING`: Post-issuance confirmation polling (Pattern 4). Shows "Pending..." progressing to "N/6 conferme". Auto-dismiss at 6/6. -10. Result banner shows final status with tappable txid (D-11). The multi-step progress indicator is replaced by the result banner. - -**On failure at any step:** -- The step shows a red X with the error message. -- A "Riprova" button (for IPFS) or suggestion text (for classified RPC errors) is shown. -- Other completed steps remain visible with green checkmarks so the user knows what succeeded. -- The user can navigate away to fix the issue (e.g., add RVN to wallet, change IPFS settings). - -### Combined "Issue + Write Tag" Flow (D-13) - -**Pre-conditions:** -- Same as standard issuance flow, but `onIssueUniqueAndWriteTag` callback is non-null. -- NFC is enabled on the device. - -**Interaction sequence:** -1-4. Steps 1-4 (IPFS, Balance, Name, Issuing) are identical to the standard flow. -5. Step 5 -- `NFC_PROGRAMMING`: The step indicator shows "Programmazione tag NFC..." with the NFC wait animation (Pattern 5). The phone's NFC dispatch activates. User holds phone to tag. -6. Tag is detected, keys are derived, NDEF URL is written, chip is registered on backend. -7. Step 6 -- `CONFIRMING`: Confirmation polling begins (same as standard flow). -8. Result banner shows combined success with txid and registration status. - -**On NFC programming failure:** -- The `NFC_PROGRAMMING` step shows a red X with the error message from the tag operation. -- "Riprova" button re-enters the NFC wait state (step resets to NFC_PROGRAMMING in-progress). -- The asset issuance from step 4 is already on-chain and NOT rolled back. The user can retry NFC programming or navigate away and program the tag later via the standalone write-tag flow. - -### Revoke Flow (bug fix) - -**Interaction sequence (unchanged, but result handling fixed):** -1. User selects REVOKE mode, enters asset name and reason. -2. Taps "Revoca asset" (NotAuthenticRed button). -3. Button shows loading spinner (existing behavior). -4. `viewModelScope.launch` calls `am.revokeAsset(...)`. -5. **Fixed behavior (D-09 implicit):** The `AssetOperationResult` returned by `am.revokeAsset()` is captured. If `result.success` is true: green banner "Asset revocato". If false: red banner with the error from `result.error`. -6. **Previous bug:** The result was discarded and success was always set to true. - -### Timeout Handling Flow (D-08) - -**Interaction sequence (after RPC timeout):** -1. Step 4 (`ISSUING`) shows a timeout error: amber warning "Richiesta timeout. Verifica su explorer." -2. The ViewModel does NOT re-broadcast. Instead, it calls `RavencoinPublicNode.callElectrumRawOrNull("blockchain.transaction.get", listOf(txid, true))` to check if the tx was mined. -3. If the txid is known and on-chain: the flow advances to step 5 (confirmation tracking) treating it as success. -4. If txid is unknown: the flow shows the timeout error with "Riprova manualmente" text. No auto-retry. - -### Confirmation Polling Cancel - -If the user navigates away from `IssueAssetScreen` during confirmation polling: -1. The `viewModelScope.launch` coroutine continues running (it is scoped to the ViewModel, not the composable). -2. When 6 confirmations are reached, the state is silently updated but no UI is visible (the screen is gone). -3. The user sees the confirmed asset on `WalletScreen` on next sync (D-12). -4. No system notification is sent (deferred per CONTEXT.md). - ---- - -## Implementation Notes - -### New State: `IssueStep` sealed class - -A new sealed class in `MainActivity.kt` (ViewModel layer) drives the multi-step progress indicator (as specified in Research Pattern 2): - -```kotlin -sealed class IssueStep { - object Idle : IssueStep() - data class InProgress(val step: StepName) : IssueStep() - data class Success(val step: StepName) : IssueStep() - data class Failed(val step: StepName, val error: String, val canRetry: Boolean) : IssueStep() - - enum class StepName { - IPFS_UPLOAD, - BALANCE_CHECK, - NAME_CHECK, - ISSUING, - CONFIRMING, - NFC_PROGRAMMING // Only for combined flow - } -} -``` - -The composable receives `currentStep: IssueStep` as a new parameter. When `currentStep is Idle`, the progress indicator is hidden and the submit button shows normally. When `currentStep is InProgress/Success/Failed`, the progress indicator replaces the submit button. - -### New String Keys in `AppStrings.kt` - -| Group | Keys (EN) | Keys (IT) | -|-------|-----------|-----------| -| Step labels | `stepIpfsUpload`, `stepBalanceCheck`, `stepNameCheck`, `stepIssuing`, `stepNfcProgramming`, `stepConfirming`, `stepComplete` | same keys, Italian values | -| Error messages | `issueErrorInsufficientFunds`, `issueErrorDuplicateName`, `issueErrorNodeUnreachable`, `issueErrorTimeout`, `issueErrorFeeEstimation`, `issueErrorIpfsFailed`, `issueErrorIpfsAuth`, `issueErrorInvalidAddress` | same keys, Italian values | -| Error suggestions | `issueErrorSuggestionInsufficientFunds`, `issueErrorSuggestionDuplicate`, `issueErrorSuggestionNodeUnreachable`, `issueErrorSuggestionTimeout`, `issueErrorSuggestionFeeEstimation`, `issueErrorSuggestionIpfs`, `issueErrorSuggestionIpfsAuth`, `issueErrorSuggestionInvalidAddress` | same keys, Italian values | -| Confirmation | `confirmPending`, `confirmProgress`, `confirmComplete` | same keys, Italian values | -| Balance warnings | `balanceWarningRoot`, `balanceWarningSub`, `balanceWarningUnique` | same keys, Italian values | -| Revoke | `revokeSuccess`, `revokeFailed` (may already exist, verify) | same | - -Total: approximately 24 new key-value pairs per language (EN + IT fully, 7 remaining locales cloned from EN). - -### Files Modified - -- `MainActivity.kt`: - - New `IssueStep` sealed class - - New `classifyIssuanceError` private method - - Enhanced catch blocks in `issueRootAsset`, `issueSubAsset`, `issueUniqueToken` (lines 1611-1677) - - Enhanced `processIssueAndWrite` with step state propagation (lines 2233-2325) - - Fixed `revokeAsset` result handling (line 1714-1729) - - New confirmation polling coroutine (post-issuance) - - New `currentStep: IssueStep` state variable (visible to composable) - -- `IssueAssetScreen.kt`: - - New composable: `MultiStepProgressIndicator(currentStep: IssueStep)` - - New composable: `ConfirmationProgressRow(confirmations: Int)` - - New composable: `PreIssuanceWarning(warningType: WarningType?)` - - Extended: `resultSuccess` banner block (lines 256-269) with tappable txid - - Modified: submit button area gated on `currentStep is IssueStep.Idle` - - New parameter: `currentStep: IssueStep` added to the `IssueAssetScreen` function - - Revoke success result uses `AssetOperationResult.success` instead of always true - -- `AppStrings.kt`: ~24 new key-value pairs per language -- `WriteTagScreen.kt`: No changes (standalone write-tag flow unchanged) -- `Theme.kt`: No changes (reuse existing tokens) - -### What Does NOT Change - -- `WalletManager.issueAssetLocal()` (C-02) -- `RpcClient` internals (C-02) -- `IssueAssetScreen` composable callback signatures (C-03) -- only adds `currentStep` parameter -- `AssetManager.kt` issuance method signatures -- `WriteTagScreen.kt` composable and `WriteTagStep` enum -- Existing result banner visual structure (extended, not replaced) -- Existing submit button color logic (RavenOrange/NotAuthenticRed/AuthenticGreen per mode) - -### Em-Dash Audit - -All new Italian and English strings added in Phase 40 must be audited for the em dash character (U+2014). The strings above use the apostrophe character `'` for Italian elisions like "disponibilita'" and `...` (three periods) for trailing ellipsis. No em dashes. The checker must reject any plan that introduces U+2014. - -### Accessibility - -- Each step row in the progress indicator must have `contentDescription` reflecting the step name and status (e.g., "Step 1: Caricamento IPFS, completato"). -- The NFC wait animation in the combined flow step must announce "Avvicina il tag NFC al telefono" via TalkBack when it becomes active. -- The tappable txid must be announced as a link: "Txid [short form], tap to open in block explorer". -- Pre-issuance warning cards must announce the warning type and amount. -- Touch targets: the txid clickable area must be at least 48dp tall (use `Modifier.defaultMinSize(minHeight = 48.dp)` on the clickable row). - ---- - -## Checker Sign-Off - -- [ ] Dimension 1 Copywriting: PASS -- [ ] Dimension 2 Visuals: PASS -- [ ] Dimension 3 Color: PASS -- [ ] Dimension 4 Typography: PASS -- [ ] Dimension 5 Spacing: PASS -- [ ] Dimension 6 Registry Safety: PASS (Android native, no registries) - -**Approval:** pending - ---- - -## Notes - -**Phase scope.** Phase 40 makes the issuance error/UX path informative and actionable. No new top-level screens are created. All new UI elements (multi-step progress indicator, error classification banner, pre-issuance validation warning, confirmation progress row, tappable txid) live inside the existing `IssueAssetScreen.kt` composable. - -**Reused Phase 20/30 patterns (do not re-define):** -- Button loading spinner (20.dp white CircularProgressIndicator, 2.dp stroke, 30% opacity disabled) -- Result banner (Card with AuthenticGreenBg/NotAuthenticRedBg, border, icon, message) -- Error card (NotAuthenticRedBg + NotAuthenticRed border + error icon) -- `retryWithBackoff` utility (5x exp backoff) for safe-error retry -- `isTransientError()` for safe-error classification -- `viewModelScope.launch` + `withContext(Dispatchers.IO)` for async operations -- `LocalStrings.current` for all user-facing text - -**New Phase 40 patterns:** -- Multi-step progress indicator (vertical timeline with step states: pending/in-progress/completed/failed) -- Error classification banner (two-line: error + suggested action, or error + retry button) -- Pre-issuance validation inline warning (amber card below form fields) -- Confirmation progress row (N/6 with amber-to-green transition, auto-dismiss at 6) -- Tappable txid link in result banner (opens block explorer) -- NFC programming step embedded in the combined flow's progress indicator (replaces external `WriteTagScreen` for the combined path) - -**Source files touched (UI only):** -- `IssueAssetScreen.kt`: multi-step progress indicator, pre-issuance warnings, tappable txid, confirmation progress -- `MainActivity.kt`: error classification, step state management, revoke bug fix, confirmation polling -- `AppStrings.kt`: ~24 new string keys per language -

Failed sub-asset branches return a `partial: true` flag and `errors: [...]` array in the response. Successful branches still return data. -- **D-04:** Limit concurrent sub-asset RPC calls to 5-10 via a simple semaphore or chunked batching.

Run once at startup too. -- **D-08:** `nfc_counters` table: NEVER cleaned up. It is the anti-replay mechanism for NTAG 424 DNA tag verification. Removing counters would allow tag replay attacks. - -### SQLite Backup -- **D-09:** Replace raw file copy in backup flow with `better-sqlite3` `.backup()` API. This produces a consistent snapshot under WAL mode, safe under concurrent writes. -- **D-10:** Backup frequency: every 6 hours. Retention: keep last 3 backups (18-hour rotating window). Encrypt output with `openssl enc` (preserve existing encryption pattern). -- **D-11:** Update `docker-compose.yml` backup container to use `sqlite3` CLI `.backup` command (the container doesn't have Node.js). The in-process Node.js backup (D-09) handles runtime; the compose backup is an additional safety layer. - -### CLI Database Explorer -- **D-12:** Add `npm run db:explore` script. Opens a read-only REPL with pre-built commands: `.assets` (list registered assets), `.brands` (list brands), `.revoked` (list revoked assets), `.stats` (table row counts). Uses `better-sqlite3` in read-only mode to protect the permanent database. -- **D-13:** CLI tool is read-only — no write operations, no schema changes. The database is permanent and must never be altered or deleted by tooling. - -### Critical Constraints -- **C-01:** Existing SQLite database is permanent. No migration may delete or alter existing tables in a backward-incompatible way. New columns must be additive (ALTER TABLE ADD COLUMN with DEFAULT). -- **C-02:** All API changes must be backward-compatible with existing Android app versions (consumer + brand flavors) and the Next.js frontend.

It must never be truncated, cleaned, or altered. - -### Claude's Discretion -- Exact concurrency limit value (5 vs 10) -- Backup retention pruning implementation -- REPL command implementation details (readline vs repl module) -- Backup container update approach in docker-compose.yml -- Error message wording in partial hierarchy responses - - - -## Canonical References - -**Downstream agents MUST read these before planning or implementing.** - -### Backend Entry Points -- `backend/src/index.ts` — Express app setup, server start, middleware mounting.

Research - -**Researched:** 2026-04-25 -**Status:** Research complete - -## 1. unhandledRejection + uncaughtException Handler - -### Current State -- `backend/src/index.ts:225` has Express error middleware — catches sync errors in route handlers only -- No `process.on('unhandledRejection')` or `process.on('uncaughtException')` anywhere in codebase -- Unhandled promise rejections currently crash the process with `UnhandledPromiseRejectionWarning` (Node 20) -- Docker `restart: unless-stopped` brings it back, but without graceful cleanup - -### Implementation Approach -Insert handlers in `index.ts` BEFORE `app.listen()` (line 230), after all middleware mounting: - -``` -process.on('unhandledRejection', (reason, promise) => { - console.error('[FATAL] Unhandled Rejection:', reason) - // graceful shutdown: close HTTP server, close SQLite - server.close(() => process.exit(1)) -}) - -process.on('uncaughtException', (err) => { - console.error('[FATAL] Uncaught Exception:', err.message) - console.error(err.stack) - process.exit(1) -}) -``` - -Key decision: `unhandledRejection` attempts graceful shutdown (close HTTP + SQLite). `uncaughtException` exits immediately — the process is in an undefined state. - -### Integration -- Must capture the server instance from `app.listen()` to close it -- Must export or access the SQLite db instance from cache.ts to close it safely -- `getDb()` returns singleton — can call `getDb().close()` after server stops - -### Concerns -- Express error handler at line 225 should remain as-is (catches sync route errors) -- The process-level handlers are a safety net, not a replacement - -## 2. Parallel Asset Hierarchy Fetching - -### Current State -- `ravencoin.ts:220-232` — `getAssetHierarchy` uses sequential `for` loop -- Each iteration calls `listSubAssets(sub)` which makes 2 parallel RPC calls internally -- N sub-assets = N serial iterations = N*2 total RPC calls, sequential per sub-asset -- No error isolation: one failed sub-asset RPC breaks the entire hierarchy response - -### Implementation Approach - -Replace sequential `for` with chunked `Promise.allSettled`: - -```typescript -async getAssetHierarchy(parentAsset: string): Promise { - const subAssets = await this.listSubAssets(parentAsset) - const variants: Record = {} - const errors: Array<{assetName: string, error: string}> = [] - - // Chunk sub-assets into batches of 5 to limit concurrent RPC calls - const CONCURRENCY = 5 - for (let i = 0; i < subAssets.length; i += CONCURRENCY) { - const chunk = subAssets.slice(i, i + CONCURRENCY) - const results = await Promise.allSettled( - chunk.map(sub => this.listSubAssets(sub)) - ) - results.forEach((result, idx) => { - if (result.status === 'fulfilled' && result.value.length > 0) { - variants[chunk[idx]] = result.value - } else if (result.status === 'rejected') { - errors.push({ assetName: chunk[idx], error: (result.reason as Error).message }) - } - }) - } - - const response: AssetHierarchy & { partial?: boolean; errors?: Array<{assetName: string; error: string}> } = { - parent: parentAsset, - subAssets, - variants - } - if (errors.length > 0) { - response.partial = true - response.errors = errors - } - return response -} -``` - -### Concurrency Limit -- D-04 says 5-10. Choose 5 (conservative — protects Ravencoin RPC node from overload) -- Chunked batching: split array into chunks of 5, await `Promise.allSettled` per chunk sequentially -- This avoids firing 200 concurrent RPC calls while still parallelizing within each chunk - -### Response Shape -- Add `partial: true` and `errors: [{assetName, error}]` when any sub-branch fails -- Existing clients ignore unknown fields (backward-compatible per C-02) -- `AssetHierarchy` interface needs optional `partial` and `errors` fields - -## 3. listassets Pagination - -### Current State -- `listSubAssets` hardcodes count=200 -- Hierarchy endpoint `GET /api/assets/:name/hierarchy` has no pagination params -- Brands with >200 sub-assets get silently truncated results - -### Implementation Approach - -Add optional `?limit=N&offset=M` to the hierarchy route: - -```typescript -// assets.ts hierarchy route -router.get('/:assetName/hierarchy', async (req, res) => { - const limit = Math.min(Number(req.query.limit) || 200, 1000) - const offset = Number(req.query.offset) || 0 - // ... pass to service -}) -``` - -Modify `listSubAssets` to accept optional limit/offset: -```typescript -async listSubAssets(parentAsset: string, limit = 200, offset = 0): Promise { - const [subs, uniques] = await Promise.all([ - this.call('listassets', [`${parentAsset}/*`, false, limit, offset]), - this.call('listassets', [`${parentAsset}/#*`, false, limit, offset]) - ]) - return [...(subs ??

SQLite Backup via .backup() API - -### Current State -- Docker backup container uses `openssl enc` directly on `/data/raventag.db` file -- Raw file copy under WAL mode can produce inconsistent backups (WAL file not included) -- `better-sqlite3` v9.4.3 has `.backup()` method — synchronous, safe under concurrent WAL writes -- No in-process Node.js backup exists - -### Implementation Approach - -**Part A: In-process Node.js backup** (new file `backend/src/services/backup.ts`): - -```typescript -import Database from 'better-sqlite3' -import { execSync } from 'child_process' -import { getDb } from '../middleware/cache.js' - -const BACKUP_INTERVAL = 6 * 60 * 60 * 1000 // 6h -const MAX_BACKUPS = 3 -const BACKUP_DIR = process.env.BACKUP_DIR ??

For typical RavenTag database sizes (a few MB), this takes <100ms — acceptable. If DB grows large, could use `backupDb.backup(source, { progress: true })` for incremental approach, but not needed now. - -## 6.

Validation Architecture - -### What Must Be Verified -1. **unhandledRejection**: Process does not crash on unhandled promise rejection — handler logs and exits gracefully -2. **Parallel hierarchy**: Concurrent sub-asset fetches complete faster than sequential. Partial failures return partial data. -3. **Pagination**: Hierarchy endpoint accepts limit/offset. Response includes metadata envelope. Omitting params preserves default behavior. -4. **Cleanup**: request_logs older than 30 days are deleted. nfc_counters is untouched. -5. **Backup**: `.backup()` API produces consistent snapshot. Docker backup container uses `sqlite3` CLI. -6. **CLI**: `npm run db:explore` opens read-only REPL. Pre-built commands work. - -### Nyquist Dimensions -- **Dimension 1 (Goal achievement):** Backend is stable — no unhandled rejection crashes, hierarchy responses are fast, logs don't grow unbounded, backups are safe -- **Dimension 2 (Requirement coverage):** All 5 requirements from ROADMAP.md addressed -- **Dimension 3 (Context fidelity):** All 13 D-0x decisions and 3 C-0x constraints honored -- **Dimension 4 (Code correctness):** TypeScript compiles, existing API responses unchanged for default params -- **Dimension 5 (Backward compatibility):** All API changes are additive. Existing Android + frontend clients unaffected. -- **Dimension 6 (Security):** nfc_counters preserved (anti-replay). Backup encrypted. CLI read-only. -- **Dimension 7 (Edge cases):** Empty sub-assets list, RPC failure on partial branches, zero logs to clean, backup dir missing -- **Dimension 8 (Should-not regressions):** Existing search, verify, revocation endpoints unchanged - ---- - -*Research complete.
