# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-24)

**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 1 — Data Foundation

## Current Position

Phase: 1 of 4 (Data Foundation)
Plan: 2 of TBD in current phase
Status: In progress
Last activity: 2026-02-24 — Completed 01-02 (HealthCheckModel + AlertEventModel unit tests)

Progress: [██░░░░░░░░] 20%

## Performance Metrics

**Velocity:**
- Total plans completed: 2
- Average duration: ~17 min
- Total execution time: ~0.57 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01-data-foundation | 2 | ~34 min | ~17 min |

**Recent Trend:**
- Last 5 plans: 01-01 (8 min), 01-02 (26 min)
- Trend: —

## 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

### Pending Todos

None yet.

### Blockers/Concerns

- PITFALL-2: Health probe scheduler must be a separate named Cloud Function export, not piggybacked on `processDocumentJobs`
- 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_at` indexes in Phase 1 migrations — query performance depends on this from day one
