Summary

FED-M1-06 — Adds mosaic gateway doctor [--json] [--config <path>] for tier-aware health reporting (postgres + valkey + pgvector). JSON mode emits a single parseable TierHealthReport for CI consumption; exit 1 on red.

Refactor: tier probes lifted from gateway to storage

The probes from apps/gateway/src/bootstrap/tier-detector.ts (FED-M1-04) needed to be reused by the new doctor command, but gateway is an app — not a library. Lifted them to @mosaicstack/storage:

  • detectAndAssertTier(config) — fail-fast on first failure (used by gateway boot)
  • probeServiceHealth(config) — non-throwing, runs ALL required probes, returns TierHealthReport with overall green/red verdict (used by doctor)
  • All 4 probe behaviors preserved verbatim from FED-M1-04 (verified by reviewer)

Old apps/gateway/src/bootstrap/tier-detector.ts + spec deleted; gateway main.ts now imports from @mosaicstack/storage.

Cycle break

Storage couldn't take a dependency on @mosaicstack/config (config already depends on storage for StorageConfig). Defined a local structural TierConfig interface in tier-detection.ts capturing only the fields the probes use. Callers continue passing full MosaicConfig objects via structural compatibility.

Tests

  • packages/storage/src/tier-detection.spec.ts22 tests (11 ported + 11 new covering probeServiceHealth, real-timer assertion, federated non-bullmq branch, lazyConnect)
  • packages/mosaic/src/commands/gateway-doctor.spec.ts12 tests (JSON contract, exit codes, output format, --config override, console.log silence in JSON mode)
22 passed (22)   — tier-detection
12 passed (12)   — gateway-doctor

Process notes

  • Independent code review (sonnet) flagged 2 important + 2 minor test gaps; all addressed in the same PR
  • Independent verifier (haiku) confirmed surface claims (file paths, exports, deletion of old files, test counts)
  • Cycle was caught by pnpm typecheck post-fix and triaged by structural typing rather than moving MosaicConfig

Test plan

  • CI green
  • Manual smoke: mosaic gateway doctor against a running standalone stack returns green
  • Manual smoke: mosaic gateway doctor --json produces valid JSON

Adds `mosaic gateway doctor [--json] [--config <path>]` for tier-aware
health reporting (postgres, valkey, pgvector). JSON mode emits a single
parseable TierHealthReport for CI consumption; exit 1 on red.

Refactors gateway-internal tier probes into @mosaicstack/storage so the
same probe logic is reused by both the gateway boot path
(detectAndAssertTier — fail-fast on first failure) and the doctor
command (probeServiceHealth — non-throwing, runs all probes, returns
report). Old apps/gateway/src/bootstrap/tier-detector.* files removed.

A local TierConfig interface in tier-detection.ts captures the minimal
structural shape from MosaicConfig without importing @mosaicstack/config
(would create a cycle since config already depends on storage for
StorageConfig).

Tests:
- packages/storage/src/tier-detection.spec.ts — 22 tests (11 ported from
  gateway tier-detector, 11 new for probeServiceHealth + timing + branch
  coverage)
- packages/mosaic/src/commands/gateway-doctor.spec.ts — 12 tests for
  JSON contract, exit codes, output format, --config override
