v2: Migrate to Hono + TypeScript Worker with Durable Object

[whoabuddy]

Summary

Complete rewrite of agent-news from Cloudflare Pages (vanilla JS, KV storage) to a Cloudflare Worker (Hono + TypeScript, Durable Object with SQLite).

• Storage: Single Durable Object (NewsDO) with SQLite replaces all KV fan-out reads. Signal POST goes from 7 KV writes to 1 atomic SQL transaction. Brief compile goes from 200+ parallel KV reads to 1 JOIN query.
• Framework: Hono + TypeScript with strict mode, replacing vanilla JS Pages functions
• Auth: BIP-322 simple signature verification on all 6 write endpoints (closes Add BIP-322 signature verification to all authenticated endpoints #10)
• Classifieds fix: Proper x402 402 response instead of 500 (fixes POST /api/classifieds returns 500 (Worker exception) when valid fields provided #4, POST /api/classifieds returns HTTP 500 (Worker error 1101) for all requests #9)
• CI/CD: GitHub Actions for typecheck, deploy (staging/production), and release-please (closes [prod-grade] Missing: TypeScript configuration (tsconfig.json) #5, [prod-grade] Missing: CI workflows (GitHub Actions) #6, [prod-grade] Missing: migrate wrangler.toml to wrangler.jsonc #7, [prod-grade] Missing: release-please automated release management #8)
• Migration: Script to export old KV data and import into new DO

Architecture

Component	Old (Pages)	New (Worker)
Runtime	Pages Functions (vanilla JS)	Cloudflare Worker (Hono + TS)
Storage	KV (SIGNAL_KV)	Durable Object SQLite + KV (rate limits, cache)
Auth	None	BIP-322 signature verification
Schema	Implicit KV keys	7 SQL tables with indexes and foreign keys
Config	wrangler.toml	wrangler.jsonc (staging + production)

Endpoints (25+)

All original endpoints ported 1:1 plus new ones (migration, internal APIs). Full manifest at GET /api.

Files

• src/lib/ — types, constants, validators, helpers, DO client
• src/middleware/ — logger (worker-logs RPC), rate limiting (KV)
• src/objects/ — NewsDO (SQL schema, all entity CRUD), schema definitions
• src/routes/ — 14 route files for all API endpoints
• src/services/ — agent resolver, auth (BIP-322), x402 payment
• scripts/ — KV-to-DO migration script
• .github/workflows/ — CI, deploy, release-please

Test plan

• npm install && npx tsc --noEmit passes
• npx wrangler dev serves static assets and health endpoint
• Review SQL schema and queries for correctness
• Review BIP-322 auth implementation
• Review x402 classifieds payment flow (no more 500)
• Deploy to staging and run seed.sh
• Run migration script against staging with test data
• Verify all endpoints return expected responses

Review: v2 Migrate to Hono + TypeScript Worker with Durable Object

Thorough review of the full diff (~6k new lines). This is a high-quality rewrite — clean architecture, proper typing, major perf gains (KV fan-out → SQL JOINs). A few issues to address before production.

Security (HIGH)

1. Migration endpoints have no auth
POST /api/internal/migrate and /api/internal/migrate/status are publicly accessible. Anyone can inject arbitrary records into the DO. Recommend:

• Add a shared secret check (e.g. X-MIGRATION-KEY header matched against a Worker secret)
• Or gate behind ENVIRONMENT !== 'production'
• Or remove the routes entirely after migration and deploy

2. BIP-322 auth only supports P2WPKH (bc1q) addresses
verifyBIP322Simple() always derives P2WPKH from the recovered pubkey. Agents with P2TR (bc1p/Taproot) addresses — which many AIBTC agents use — cannot authenticate. The header byte range 39-42 is accepted (P2WPKH) but 31-34 (P2PKH compressed) and 35-38 (P2SH-P2WPKH) will silently fail (no bypass, just rejection). Worth documenting which address types are supported and whether Taproot support is planned.

3. countBefore uses string-interpolated table names
In the migration handler: `SELECT COUNT(*) as n FROM ${table}` — the table name is validated against validTypes, but this pattern is fragile. Safer: use a const map { beats: "beats", ... } and look up from that.

Architecture (MEDIUM)

4. totalSignals not incremented on same-day filing
In POST /signals streak logic (news-do.ts ~line 791):

if (currentStreakRecord.last_signal_date === today) {
  totalSignals = currentStreakRecord.total_signals ?? 1; // don't double-count
}

This means multiple signals per day don't increment total_signals. This seems like a bug — total_signals should count all signals, independent of streak logic. The streak staying the same is correct, but total signals should still increment.

5. Brief compile requires BIP-322 auth but is read-only
POST /api/brief/compile does a SQL JOIN and returns data — no mutations. Requiring BIP-322 auth here means only authenticated agents can trigger compilation, which blocks automated cron-based compilation. Consider making this rate-limited only (no auth), or using a separate internal route for cron.

6. Rate limiting not enforced at DO level
The IP-based rate limits use KV and live only in the Worker routes. The DO accepts unlimited requests. If another Worker or script has the DO binding, rate limits are bypassed. Not urgent, but worth noting for the security model.

Minor

7. Hardcoded skills list — src/routes/skills.ts has 7 static skill entries. Adding a beat requires a code change + deploy. Consider KV/DO storage for skills.

8. No tests — For a production rewrite touching auth, payments, and data migration, automated tests would significantly de-risk deployment. Even a few integration tests covering: signal creation → streak update, BIP-322 auth rejection, classifieds 402 flow.

9. CLASSIFIED_CATEGORIES type assertion — In classifieds.ts line ~113:

const validCategories = CLASSIFIED_CATEGORIES as readonly string[];

This cast loses the literal union type. Consider CLASSIFIED_CATEGORIES.includes(category as typeof CLASSIFIED_CATEGORIES[number]) or a Set check.

Positive Highlights

• Signal POST going from 7 KV writes to 1 atomic SQL transaction is a major improvement
• rowToSignal() extraction eliminated 4x duplication
• Classifieds 402 fix is clean and correct
• BIP-322 auth implementation (bech32 encoder, message hashing, pubkey recovery) is solid for P2WPKH
• Migration script is idempotent and well-structured (batched, paginated KV reads, dependency order)
• CI/CD pipeline with release-please is production-ready
• Global error handler properly hides details in non-local envs

Overall: strong rewrite. Address the unauthenticated migration endpoint (#1) before deploying to production. The Taproot auth gap (#2) and total_signals bug (#4) are worth fixing but not blockers for staging.

Review: v2 Migrate to Hono + TypeScript Worker with Durable Object

Thorough review of the full ~10k line diff. Overall: this is an excellent rewrite. The move from Pages Functions + KV fan-out to Worker + Durable Object SQLite is architecturally sound. Signal POST going from 7 KV writes to 1 atomic SQL transaction is a huge win. Code quality is high — no any types, consistent error handling, clean separation between routes/services/DO. The worker-logs logger middleware is an exact pattern match to x402-sponsor-relay. BIP-322 auth on all write endpoints is a major security improvement over the old code.

Below are the issues I found, organized by severity.

---

🔴 Security — Should fix before merge

1. Migration endpoints are unauthenticated (src/index.ts)

POST /api/internal/migrate and POST /api/internal/migrate/status have zero auth. Any external caller who knows the Worker URL can bulk-import arbitrary data into the DO. Should add at minimum a shared secret header check, restrict to wrangler dev only, or remove after migration is complete.

2. Brief inscribe POST doesn't verify BIP-322 signature (src/routes/brief-inscribe.ts)

POST /api/brief/:date/inscribe calls validateSignatureFormat(signature) which only checks that it looks like base64. It never calls verifyAuth() or verifyBIP322Simple() for actual cryptographic verification. Compare with beats.ts and signals.ts which properly call verifyAuth(). Anyone can claim an inscription with a plausible-looking fake base64 string.

3. Brief inscribe PATCH has zero auth and zero rate limiting (src/routes/brief-inscribe.ts)

PATCH /api/brief/:date/inscribe has no authentication at all — no BIP-322, no signature format check, nothing. Any caller can update inscription data on any brief. The rate limit middleware is only applied to POST, not PATCH.

4. CORS headers missing from 402 payment response (src/services/x402.ts)

buildPaymentRequired() returns a raw new Response(...) that bypasses Hono's CORS middleware chain. Browser-based agents attempting POST /api/classifieds without a payment header will get a CORS error instead of the intended 402. Fix: either use c.json() within the route handler, or add CORS headers to the raw response.

---

🟡 Correctness — Should fix before production

5. Explicit BEGIN/COMMIT in DO exec() may conflict with Cloudflare's implicit transactions (src/objects/news-do.ts)

Signal creation wraps multiple statements in explicit BEGIN/COMMIT inside a single sql.exec() call. Cloudflare's DO SQLite API already runs exec() atomically. If the runtime wraps exec() in an implicit transaction, the explicit BEGIN would cause "cannot start a transaction within a transaction." Needs verification against Cloudflare runtime — consider removing explicit BEGIN/COMMIT and relying on multi-statement exec() atomicity, or using SAVEPOINT/RELEASE.

6. Streak totalSignals undercounts on same-day signals (src/objects/news-do.ts)

When a second signal is filed on the same Pacific day, the code resets totalSignals = currentStreakRecord.total_signals without incrementing — but the signal INSERT still runs unconditionally. So streaks.total_signals drifts below the actual count. Fix: always increment totalSignals regardless of streak logic (streak and total count are orthogonal).

7. Signal field name changes break existing clients

Field names changed from camelCase to snake_case: btcAddress → btc_address, beat → beat_slug, content → body, timestamp → created_at. Additionally, headline, sources, and tags are now required (were optional). This breaks all existing signal consumers. If this is intentional (v2 is a clean break), document it explicitly. If not, consider a compatibility layer or at least a migration guide for clients.

8. Beat PATCH doesn't verify ownership (src/routes/beats.ts)

PATCH /api/beats/:slug verifies BIP-322 auth (valid signature) but doesn't check that btc_address === beat.created_by. Any authenticated agent can update any beat's metadata. The old code enforced claimant ownership.

9. Report endpoint timezone inconsistency (src/objects/news-do.ts)

The report query uses DATE(created_at) which extracts the date in UTC, but compares against getPacificDate() (Pacific timezone). A signal filed at 11 PM Pacific on March 3 has created_at = '2026-03-04T07:00:00.000Z', so DATE(created_at) = '2026-03-04' while today = '2026-03-03'. Brief compilation correctly uses getPacificDayStartUTC() — the report endpoint should match.

10. Placeholder KV namespace IDs in wrangler.jsonc

All three environments use "placeholder-*-kv-id". Deploy will fail without real KV namespace IDs. Probably already known, but flagging to make sure.

---

🟢 Minor / Observations

11. Logger middleware is set up but never called in route handlers. The infrastructure is in place but no route calls c.get("logger"). Missed observability opportunity — consider logging auth failures, payment events, signal creation, and rate limit hits.

12. Correction signals inflate aggregate counts. /api/correspondents and /api/report count all signals including corrections (correction_of IS NOT NULL). Consider filtering: WHERE correction_of IS NULL in aggregate queries.

13. getMigrationStatus uses POST instead of GET (src/lib/do-client.ts). This is a read-only count query — semantically should be GET.

14. No lint or test steps in CI. ci.yml only runs tsc --noEmit. For production standards, consider adding a linter. Tests are a larger investment but worth planning for.

15. rowToSignal uses as unknown as Signal double cast (src/objects/news-do.ts). Pragmatic for SQLite rows, but means TypeScript can't verify the row actually contains all Signal fields. If schema changes, this will silently produce malformed objects.

16. Missing indexes on signals.correction_of and classifieds.category. Low priority at current data volumes, but worth adding if query patterns grow.

17. No timeout on x402 relay fetch (src/services/x402.ts). If the relay is slow/unreachable, the worker waits until CF's execution timeout. Consider AbortController with a 10s timeout.

---

✅ What's done well

• Architecture: Pages → Worker + DO + SQLite is the right move. Single-DO singleton eliminates concurrency issues.
• Auth: BIP-322 on all 6 write endpoints. Bitcoin message hash is correctly implemented. Timestamp window prevents replay.
• x402 fix: Proper 402 instead of 500 for classifieds (fixes #4, #9). Uses correct payment-required header (v2).
• Rate limiting: Correctly avoids incrementing counter on 429 responses — the old bug (landing-page #304) is NOT present here.
• Worker-logs: Logger middleware is character-for-character identical to x402-sponsor-relay pattern.
• Release-please: Config matches x402-sponsor-relay exactly.
• TypeScript: Strict mode, no any types, all unknown properly narrowed.
• Migration script: Idempotent, dependency-ordered, batched, error-resilient.
• Dependencies: @noble/hashes + @noble/secp256k1 are the gold standard for JS crypto. No unnecessary deps.

This is strong work. The security items (1-4) should be addressed before merge. The correctness items (5-10) should be addressed before production traffic. Everything else is polish.

Happy to re-review after changes.

[biwasxyz]

PR #12 Review: v2 — Hono + TypeScript Worker with Durable Object

The architecture upgrade (KV → DO SQLite, vanilla JS → Hono/TS, real BIP-322 auth) is solid in concept, but there are several critical issues that need addressing before merge.

---

P0 — Must Fix Before Merge

1. Migration script is broken — no auth header sent
scripts/migrate-kv-to-do.ts — sendBatch() and printMigrationStatus() never send the X-Migration-Key header. Every batch request will get 401'd by the Worker's auth check.

2. Migration field mapping is wrong

• Signals: script reads signal.body but v1 KV stores the field as content → all signal bodies migrate as null
• Streaks: script reads current_streak, longest_streak, last_signal_date but v1 stores current, longest, lastDate → all streaks migrate as zeros

3. KV namespace IDs are TODO placeholders
wrangler.jsonc has TODO-replace-with-actual-kv-namespace-id in all three environments (local, staging, production). Deploys will fail immediately.

4. Frontend not updated but API contract changed
No public/ files are modified, but the API response field names changed (btcAddress → btc_address, timestamp → created_at, beat → beat_slug, etc.). The entire frontend will break against the new API.

5. No response caching
V1 set Cache-Control headers on read endpoints (beats: 15s, signals: 10s, correspondents: 30s, skills: 300s). V2 has zero cache headers. Every request hits the singleton DO, which is a significant cost/latency regression and a scaling bottleneck since all traffic is serialized through one Durable Object.

---

P1 — Behavioral Regressions

6. Per-agent 4-hour signal cooldown removed
V1 enforced a 4-hour gap between signals per agent. V2 only has a generic IP rate limit (10/60s). Agents can now flood signals.

7. Beat expiry/reclaim system removed
V1's 14-day inactivity check on read + reclaim logic is entirely gone. Beats can never go inactive or be reclaimed by another agent.

8. Beat ownership check removed from signal submission
V1 verified the submitting agent owns the beat. V2 only checks the beat exists — any authenticated agent can post to any beat.

9. Brief x402 paywall + correspondent earnings removed
The entire monetization layer (402 preview → payment → earnings crediting) is gone. The earnings table exists but is only ever written with amount_sats: 0.

10. Agent status "next actions" system removed
GET /api/status/:address in v1 returned canFileSignal, waitMinutes, and a guided actions array. V2 returns raw data only. This was the primary mechanism for agent autonomy.

11. POST /api/signals now requires headline, sources, tags
These were all optional in v1. Existing agents posting without them will get 400s.

---

P2 — Security & Correctness

12. BIP-322 auth — uppercase bech32 addresses silently fail
pubkeyToP2WPKHAddress always returns lowercase, but the comparison uses the raw header value. An uppercase BC1Q... in X-BTC-Address will always fail verification. Fix: normalize to lowercase before verification.

13. validateBtcAddress accepts Taproot (bc1p) addresses
The regex allows bc1p addresses through, but auth only supports bc1q. Agents with bc1p keys will pass validation but always fail auth.

14. Failed x402 payment returns 402 instead of error
In src/routes/classifieds.ts, when verifyPayment returns { valid: false }, the code sends another 402. Automated clients will loop forever retrying payment.

15. Migration BEGIN/COMMIT without ROLLBACK
In src/objects/news-do.ts, if any SQL insert inside the loop throws, COMMIT is never reached and the transaction hangs. Wrap in try/catch with ROLLBACK.

16. Foreign keys are decorative
SQLite defaults to PRAGMA foreign_keys = OFF. The REFERENCES clauses in the schema do nothing without enabling the pragma.

17. IS NULL OR query pattern defeats index usage
The signals query uses (?1 IS NULL OR s.beat_slug = ?1) for all optional filters. SQLite can't optimize this. Build the WHERE clause dynamically instead.

18. No timeout on agent resolver external fetch
resolveAgentName() has no AbortController timeout on the fetch to aibtc.com. A slow/unresponsive API can hang brief compilation.

19. Uncaught JSON.parse on brief.json_data
src/routes/brief.ts — corrupted JSON in the DB will throw and 500.

20. PATCH /api/brief/:date/inscribe lacks rate limiting
The POST variant has inscribeRateLimit middleware but the PATCH does not.

---

P2 — Missing Functionality

Feature	V1	V2
Correspondent score formula	signals×10 + streak×5 + daysActive×2	Raw signal_count sort only
Streaks ?agent= filter	Per-agent query	Leaderboard only
Brief archive field	List of all available dates	Absent
Inscriptions endpoint	Proxy to inscribe.news	Local DB query (different data)
Report ?generate=true	Stored compiled reports	Read-only stats
Txid fallback for classifieds	On-chain verification via Hiro API	x402 relay only

---

What's Good

• Real cryptographic auth — BIP-322 verification with @noble/secp256k1 is a major upgrade from syntactic-only checks
• SQL schema — well-structured 7-table design with proper indexes replaces fragile KV fan-out
• Signal POST atomicity — 7 KV writes → 1 SQL transaction is a significant reliability improvement
• CI/CD pipeline — typecheck + lint + staging/production deploy via releases is clean
• TypeScript strict mode — catches a class of bugs at compile time

---

Recommendation

This PR needs another pass before merge. The migration script bugs (P0 #1-2) would corrupt all existing data, and the frontend incompatibility (P0 #4) would break the site immediately. Suggested next steps:

1. Fix the migration script (auth header + field mapping)
2. Fill in the KV namespace IDs
3. Decide which v1 features are intentionally dropped vs accidentally lost, and document the breaking changes
4. Either update the frontend or add a v1-compatible response format layer
5. Add cache headers back to read endpoints

Fixes pushed — BIP-322 auth + DO SQLite crash

4 commits:

1. chore: add KV namespace IDs for local dev
Added real KV namespace IDs to the top-level wrangler.jsonc binding so wrangler dev works out of the box (previously had TODO-replace).

2. feat(deps): add @scure/btc-signer and @noble/curves for BIP-322 verification

• Added @scure/btc-signer, @noble/curves, @scure/base
• Upgraded @noble/hashes from v1 → v2 (breaking import path changes: sha256 → @noble/hashes/sha2.js)

3. feat(auth): support both BIP-137 and BIP-322 signature formats
Complete rewrite of src/services/auth.ts. The old implementation only handled BIP-137 (65-byte compact recovery signatures, used by Electrum). The aibtc MCP wallet produces BIP-322 witness-serialized signatures, which were rejected as invalid.

New implementation:

• Auto-detects format: 65 bytes with header 27–42 → BIP-137, otherwise → BIP-322 witness
• BIP-137 path: Recovery-based verification, derives P2PKH/P2SH-P2WPKH/P2WPKH address from header byte range using @scure/btc-signer address functions
• BIP-322 path: Decodes witness stack (RawWitness), builds virtual to_spend transaction, constructs to_sign transaction with OP_RETURN output, computes BIP-143 sighash via preimageWitnessV0, verifies ECDSA signature against extracted pubkey
• Legacy fallback: Tries spec-compliant BIP-322 tagged hash first (SHA256(tag) || SHA256(tag) || msg), falls back to legacy format with varint prefix for older signing tools
• Based on the battle-tested implementation from aibtcdev/landing-page
• Replaces hand-rolled bech32 encoder, RIPEMD-160 hashing, and custom address derivation with library calls

4. fix(do): split multi-statement SQL exec into individual calls
DO SQLite has an undocumented limitation: when executing multiple SQL statements in a single exec() call, only the last statement can have parameters. Signal creation concatenated INSERT statements for signal + tags + streak + earnings with spread params, causing a runtime crash.

Fix: Split into individual exec() calls for each INSERT. Atomicity is still guaranteed because each Durable Object fetch() runs in an implicit transaction. Applied to both POST (new signal) and PATCH (correction) handlers.

Verified locally

• Beat creation via MCP wallet (BIP-322) ✅
• Signal filing with tags ✅
• Brief compilation ✅
• All 3 beats, 4 signals, 1 brief created end-to-end

Review fixes pushed — migration, DO lifecycle, query safety

Ran a comprehensive review against Cloudflare DO SQLite docs and tested the full migration flow locally. Found and fixed 3 P0s and 6 P1s across 3 commits:

fix(do): replace BEGIN/COMMIT with transactionSync, fix corrections and queries

P0 fixes:

• sql.exec("BEGIN")/sql.exec("COMMIT") is forbidden in DO SQLite — the runtime throws on transaction-related statements. All 7 migration entity branches now use this.ctx.storage.transactionSync() which provides atomic rollback-on-error semantics.
• UNION ALL across 7 tables in /migrate/status caused a platform-level 500 (DO returned plain text "Internal Server Error" before Hono could handle it). Replaced with individual COUNT(*) queries per table — tested and working.

P1 fixes:

• Signal corrections silently dropped body and tags when not provided — now inherits from the original signal (consistent with how headline and sources already worked).
• INSERT OR REPLACE on briefs wiped inscription data (inscribed_txid, inscription_id set to NULL on recompile). Changed to INSERT ... ON CONFLICT(date) DO UPDATE SET text, json_data, compiled_at to preserve inscription fields.
• Unbounded result sets on /correspondents, /inscriptions, /earnings/:address — added LIMIT 200.
• DO fetch() had no error handling — uncaught exceptions terminate DO instances per Cloudflare rules. Added try/catch returning JSON error.
• Removed dead code — tagInserts/tagParams variables computed but never used after the exec split refactor.

fix(migrate): add X-Migration-Key header and fix status HTTP method

• sendBatch() was missing the X-Migration-Key header — all migration requests would 401.
• printMigrationStatus() used POST but the Worker endpoint is GET.
• Added MIGRATION_KEY to required env vars with docs.

fix(config): add assets and MIGRATION_KEY to env configs

• assets config is not inherited by environments per Cloudflare docs. Staging and production were missing it, so the static frontend (./public) would not be served in deployed environments. Added to both.
• Added MIGRATION_KEY var for local dev testing.

• Logger middleware (src/middleware/logger.ts): waitUntil + RPC logger with console fallback is an exact match to x402-sponsor-relay. ✅
• Auth service (src/services/auth.ts): Dual BIP-137 / BIP-322 implementation ported from landing-page, including @scure/btc-signer for address derivation. ✅
• x402 service: buildPaymentRequired + verifyPayment with AbortController timeout follows the same pattern as x402-api. ✅
• Rate limiting: KV-backed per-IP middleware matches the approach in landing-page. ✅
• TypeScript strict mode: No any, satisfies used for config, explicit return types on exports. ✅

🔴 Must Fix Before Staging Deploy

1. KV namespace IDs are still TODO-replace-with-actual-kv-namespace-id

wrangler.jsonc staging and production environments both have placeholder IDs. Worker will fail to deploy:

"kv_namespaces": [
  { "binding": "NEWS_KV", "id": "TODO-replace-with-actual-kv-namespace-id" }
]

Run wrangler kv namespace create NEWS_KV --env staging and --env production, then fill in real IDs.

2. Foreign key constraints are not enforced

SCHEMA_SQL has REFERENCES beats(slug) and REFERENCES signals(id) but SQLite defaults to PRAGMA foreign_keys = OFF. They're decorative as-is. Add to the constructor after schema init:

this.ctx.storage.sql.exec("PRAGMA foreign_keys = ON");

In DO SQLite this persists for the lifetime of the object instance, which is what you want.

🟡 Feature Parity Gap — Affects Arc Sensor

3. Correspondent scoring formula changed

v1 /api/correspondents returned a computed score = signals×10 + streak×5 + daysActive×2. v2 sorts by signal_count DESC only — no composite score field.

Arc's aibtc-news sensor uses score ≥ 50 to decide whether to queue a brief compilation:

const score = signals * 10 + streak * 5 + daysActive * 2;
if (score >= 50) { /* queue compile-brief task */ }

After migration, this will always be 0 because the score field won't exist on the response. Either add a computed score to the correspondents response, or Arc's sensor needs updating alongside deploy.

The data is available in the query (signal_count, current_streak, total_signals) — adding a computed score field to the response is a one-liner:

(COUNT(s.id) * 10 + COALESCE(st.current_streak, 0) * 5 + ...) as score

🟡 Minor — Low Risk

4. Dead signature field in brief-inscribe body

POST /api/brief/:date/inscribe accepts { btc_address, signature, inscription_id } and calls validateSignatureFormat(signature) after verifyAuth already ran. verifyAuth uses X-BTC-Signature from headers — the body signature is validated but never used. This is a vestigial field from v1 that will confuse callers. Either remove it from the body schema or return an error if it's present but doesn't match the header.

5. Taproot (bc1p) address error message

validateBtcAddress accepts bc1p addresses (regex ^bc1[a-zA-HJ-NP-Z0-9]{25,87}$), but auth only supports bc1q. Taproot agents pass validation and then get "Invalid signature". auth.ts already has the limitation documented in the header comment — consider returning a more explicit "Taproot (bc1p) addresses are not supported. Use a P2WPKH (bc1q) address." from verifyAuth when the address starts with bc1p.

6. BRIEFS_FREE = true — no documentation in README/wrangler.jsonc

The paywall toggle exists in constants.ts but there's no mention of it in wrangler.jsonc vars or README. Future operators won't know this flag exists. Add BRIEFS_FREE as a documented var or comment.

What's Good

• All P0/P1 security items from previous reviews resolved ✅
• DO SQLite atomicity fixed (transactionSync, individual exec calls) ✅
• Migration script has auth, correct HTTP methods, idempotent ✅
• BIP-322 + BIP-137 dual-format auth from landing-page is solid ✅
• CORS on 402 responses ✅
• AbortController timeouts on external fetches (x402 relay, agent resolver) ✅
• nodejs_compat_v2 flag is correct for @noble/curves dependency ✅
• assets per-env in wrangler.jsonc ✅
• CI/CD pipeline clean ✅
• rowToSignal() extraction eliminates duplication ✅

Recommendation

Fill in the 2 deployment blockers (#1 KV IDs, #2 foreign keys), and sync with Arc on the scoring formula (#3) before migration day. Items #4-6 are cleanup that can be follow-up PRs after staging validation.

Ready to deploy to news.aibtc.com once #1 and #2 are resolved.

Why is there a header for a bitcoin signature? We don't have that pattern anywhere else.

validateBtcAddress sounds non-standard too, what is that for? if we support BIP-137 and BIP-322 why are only certain addresses supported?

KV namespaces we can set that up and deploy before merging to verify all works (and not clobber the old deployment).

Is BRIEFS_FREE used in the code? Likely can remove and add back as a feature later.

Can add a computed score that makes sense as something we should return here.

The whole goal is to make this super easy to navigate and use by agents, so anywhere we can use clear error messages or hints to next steps is very useful (same as other listed projects).
