Subject: [PATCH 1/4] feat(tests): integration tests against real public
 testnet infrastructure

Adds end-to-end integration tests under test/integration/ that exercise
the built CLI (bin/sphere.mjs) against the Unicity public testnet:

- wss://nostr-relay.testnet.unicity.network (Nostr relay)
- https://goggregator-test.unicity.network (aggregator JSON-RPC + trustbase)
- https://unicity-ipfs1.dyndns.org (IPFS gateway for identity publish)

Three test files:
- cli-crypto: local crypto/util commands (no network, deterministic)
- cli-wallet: `sphere wallet init --network testnet` against real aggregator
  + IPFS + Nostr; parses emitted identity JSON and asserts L1Address/
  directAddress/chainPubkey shape
- cli-dm: self-DM round-trip via the real Nostr relay; exercises Sphere.init
  + Nostr connect + NIP-17 encryption + gift-wrap publish + inbox retrieval

Harness:
- test/integration/helpers.ts: createSphereEnv() provisions a fresh tmp
  profile dir with seeded testnet config; runSphere() invokes the built
  CLI via spawnSync with generous 90-120s timeouts. integrationSkip via
  SKIP_INTEGRATION=1 for CI opt-out.
- vitest.integration.config.ts: dedicated config with 120s test timeout,
  sequential single-fork execution to avoid relay rate-limits.
- vitest.config.ts: excludes test/integration/** from the default run so
  unit tests stay fast (21/21 in ~1s).
- npm run test:integration: builds + runs integration suite.

Minor CLI addition: `sphere wallet init` and `sphere wallet status` now
route to legacy top-level `init` / `status` commands (previously only
wallet subcommands like list/use/create/current/delete were routed).
This unblocks the wallet-init integration test.

Local verification: all 7 integration tests pass in ~6s total against
the live testnet endpoints.

+### Integration tests
+
+The `test/integration/` suite exercises the built CLI against real public
+infrastructure:
+
+- Nostr relay  — `wss://nostr-relay.testnet.unicity.network`
+- Aggregator   — `https://goggregator-test.unicity.network`
+- IPFS gateway — `https://unicity-ipfs1.dyndns.org`
+
+Each test creates a throwaway wallet in `/tmp` so runs are fully isolated and
+never touch real funds. Skip with `SKIP_INTEGRATION=1` when offline.
+
 ## Design principles
 
 1. **DM-native.** All controller → manager and controller → tenant traffic goes

 =?UTF-8?q?fication?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HIGH:
- helpers.ts: chmod 0700 on profile dir + config dir so secp256k1 material
  isn't world-readable on shared CI runners
- helpers.ts: startup sweep of stale sphere-cli-it-* dirs (>1h old) cleans
  up after crashed prior runs
- helpers.ts: process-level exit/SIGINT/SIGTERM/uncaughtException handlers
  shred all active SphereEnvs so killed tests don't leak wallet mnemonics
  under /tmp

MEDIUM:
- helpers.ts: env allowlist (PATH, HOME, USER, SHELL, LANG, etc.) instead
  of spreading full process.env — CI secrets (AWS_*, GITHUB_TOKEN, etc.)
  no longer reach the spawned CLI child
- helpers.ts: spawnSync uses killSignal: 'SIGKILL' — hung Nostr/IPFS
  children can't delay tests past the declared timeout
- cli-dm: inbox test now POLLS for the sent DM's nonce (20 tries × 3s)
  instead of just asserting "inbox command ran". Self-DM round-trip is
  now genuinely verified end-to-end via NIP-17 gift-wrap round-trip.
- NEW preflight.integration.test.ts: probes aggregator (HEAD),
  IPFS gateway (HEAD), Nostr relay (TLS handshake). Runs first. Failures
  tell operators whether a red CI is infra or code, rather than making
  them dig through stderr. Does NOT gate downstream tests (vitest
  evaluates skipIf at registration, before preflight's beforeAll) —
  serves as a diagnostic signal only.

LOW:
- helpers.ts: BIN_PATH resolved via import.meta.url at module load,
  removing process.cwd() fragility
- cli-dm: nonce includes random suffix (Math.random) so concurrent CI
  runs don't collide
- cli-dm: explicit expect(directAddress).toBeTruthy() in round-trip test
  prevents silent ordering-dependent pass

src/index.ts: buildLegacyArgv exported with explicit tail parameter so
it's unit-testable. The single live call site still passes
process.argv.slice(3). +28 unit tests covering every namespace branch:
  - wallet init/status remap (the round-1 change that had zero coverage)
  - wallet current/list/create/delete fall-through
  - 1:1 namespaces (balance, daemon, config, completions)
  - faucet → topup
  - nametag register/info/my/sync
  - payments/crypto/util namespace-strip
  - dm send/inbox/history
  - group/market/swap/invoice prefix
  - unknown namespace fall-through

Tests: 21 → 49 unit (+28), 7 → 10 integration (+3 preflight, DM inbox
now real). All pass in ~7s total.

 =?UTF-8?q?=E2=80=94=20polish=20integration=20test=20harness?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MEDIUM:
- cli-dm: DM inbox polling now bounded to 10 attempts × 2s (max ~60s)
  with a 180s test budget. Round 2's 20×3s could exceed the 90s test
  timeout when each spawn re-inits Sphere (trustbase + Nostr + IPFS).

LOW:
- Rename preflight.integration.test.ts → 00-preflight.integration.test.ts
  so vitest's filename-sorted sequencer actually runs it first (p > c
  sorted after cli-*). Diagnostic signal now lands before the real
  tests, not after — operators see "aggregator is reachable" BEFORE
  digging into test stderr.
- helpers.ts sweep cutoff 1h → 24h. A long vitest --watch debug session
  or legit slow concurrent run cannot have its tmpdir swept mid-flight.
- 00-preflight.ts probeTls: outer hard setTimeout bounds DNS/SYN-drop
  paths that tls.connect's own timeout option does not cover.
- helpers.ts: remove dead `dirname` import + void-suppressor.
- helpers.ts: remove uncaughtException/unhandledRejection handlers —
  they were masking vitest's own failed-test reporting. The `exit` +
  SIGINT/SIGTERM handlers still catch realistic kill paths.

Tests still 10/10 integration + 49/49 unit. No behavior change beyond
the stated fixes.

Subject: [PATCH 4/4] ci: add nightly integration-test workflow (testnet)

Schedules the real-testnet integration suite (test/integration/*.integration.test.ts)
to run at 03:07 UTC nightly + on workflow_dispatch for manual triggers.
Kept out of the default push/PR CI because these tests:
  - hit shared public infra (Nostr relay, aggregator, IPFS gateway) and
    shouldn't be triggered on every commit
  - run for minutes end-to-end
  - can flake on transient upstream hiccups

Nightly failures surface in the Actions tab but never block PRs.
On failure, tmp wallet dirs are uploaded as an artifact for debugging.
