Core value: When something breaks — an API key expires, a service goes down, a credential needs reauthorization — the admin knows immediately and knows exactly what to fix. Current focus: Phase 4 — Frontend
Current Position
Phase: 4 of 4 (Frontend) Plan: 2 of 2 in current phase Status: Complete (pending visual verification at checkpoint) Last activity: 2026-02-24 — Completed 04-02 (AlertBanner and AdminMonitoringDashboard wired into App.tsx Dashboard)
Progress: [██████████] 100%

Accumulated Context
Decisions
Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:
- Roadmap: 4 phases following data layer → services → API → frontend dependency order
- Architecture: Health probes decoupled from document processing as separate Cloud Function export
- Architecture: Analytics writes are always fire-and-forget (never await on critical path)
- Architecture: Alert recipient stored in config, not hardcoded (PITFALL-8 prevention)
- 01-01: TEXT + CHECK constraint used for enum columns (not PostgreSQL ENUM types)
- 01-01: getSupabaseServiceClient() called per-method, never cached at module level
- 01-01: checked_at column separate from created_at on service_health_checks (probe time vs DB write time)
- 01-01: Forward-only migrations only (no rollback scripts)
- 01-02: Supabase mock uses chain.then (thenability) so both .single() and direct await patterns work from one mock
- 01-02: makeSupabaseChain() factory per test — no shared mock state between tests
- 01-02: vi.mock() factories must use only inline vi.fn() to avoid Vitest hoisting TDZ errors
- 02-02: LLM probe uses claude-haiku-4-5 with max_tokens 5 (cheapest model, prevents expensive accidental probes)
- 02-02: Supabase probe uses getPostgresPool().query('SELECT 1') not PostgREST (tests actual DB connectivity)
- 02-02: Firebase Auth probe: verifyIdToken always throws; 'INVALID'/'Decoding'/'argument' in message = SDK alive = healthy
- 02-02: Promise.allSettled for probe orchestration — all 4 probes run even if one throws outside its own try/catch
- 02-02: Per-probe HealthCheckModel.create failure swallowed with logger.error — probe results still returned to caller
- [Phase 02-backend-services]: 02-01: recordProcessingEvent return type is void (not Promise) — type system prevents accidental await on critical path
- 02-03: Transporter created inside sendAlertEmail() on each call (not cached at module level) — Firebase Secrets not available at module load time
- 02-03: Suppressed alerts skip BOTH AlertEventModel.create() AND sendMail — prevents duplicate DB rows plus duplicate emails
- 02-03: Email failure caught and logged, never re-thrown — probe pipeline must continue regardless of email outage
- [Phase 02-backend-services]: runHealthProbes is a separate onSchedule Cloud Function from processDocumentJobs (PITFALL-2 compliance)
- [Phase 02-backend-services]: retryCount: 0 on runHealthProbes — 5-minute schedule makes retry unnecessary
- [Phase 02-backend-services]: runRetentionCleanup uses Promise.all() for parallel deletes across three independent monitoring tables
- [Phase 03-api-layer]: 03-02: recordProcessingEvent() instrumentation uses void return — no await at 3 lifecycle points in processJob (PITFALL-6 compliance)
- [Phase 03-api-layer]: requireAdminEmail returns 404 not 403 — does not reveal admin routes exist
- [Phase 03-api-layer]: getPostgresPool() used for aggregate SQL — Supabase JS client does not support COUNT/AVG
- [Phase 03-api-layer]: Admin env vars read inside function body not module level — Firebase Secrets timing constraint
- [Phase 04-frontend]: AlertBanner filters to active service_down/service_degraded only — recovery type is informational, not critical
- [Phase 04-frontend]: AlertEvent uses snake_case (backend raw model), ServiceHealthEntry/AnalyticsSummary use camelCase (backend admin.ts remaps)
- [Phase 04-frontend]: AdminMonitoringDashboard is self-contained with no required props
- [Phase 04-frontend]: AlertBanner placed before nav element so it shows across all tabs when admin has active critical alerts
- [Phase 04-frontend]: Alert fetch gated by isAdmin in useEffect dependency array — non-admin users never call getAlerts
Pending Todos
None yet.
Blockers/Concerns
- PITFALL-6: Each analytics instrumentation point must be void/fire-and-forget — reviewer must check this in Phase 3
- PITFALL-10: All new tables need
created_atindexes in Phase 1 migrations — query performance depends on this from day one
