Phase 2: Backend Services Verification Report

Phase Goal: All monitoring logic runs correctly — health probes make real API calls, alerts fire with deduplication, analytics events write non-blocking to Supabase, and data is cleaned up on schedule Verified: 2026-02-24T14:38:30Z Status: PASSED Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	`recordProcessingEvent()` writes to `document_processing_events` table via Supabase	VERIFIED	`analyticsService.ts:34` — `void supabase.from('document_processing_events').insert(...)`
2	`recordProcessingEvent()` returns `void` (not `Promise`) so callers cannot accidentally await it	VERIFIED	`analyticsService.ts:31` — `export function recordProcessingEvent(data: ProcessingEventData): void`
3	A deliberate Supabase write failure logs an error but does not throw or reject	VERIFIED	`analyticsService.ts:45-52` — `.then(({ error }) => { if (error) logger.error(...) })` — no rethrow; test 3 passes
4	`deleteProcessingEventsOlderThan(30)` removes rows older than 30 days	VERIFIED	`analyticsService.ts:68-88` — `.lt('created_at', cutoff)` with JS-computed ISO date; test 5-6 pass
5	Each probe makes a real authenticated API call (Document AI list processors, Anthropic minimal message, Supabase SELECT 1 via pg pool, Firebase Auth verifyIdToken)	VERIFIED	`healthProbeService.ts:32-173` — 4 individual probe functions each call real SDK clients; tests 1, 5 pass
6	Each probe returns a structured `ProbeResult` with `service_name`, `status`, `latency_ms`, and optional `error_message`	VERIFIED	`healthProbeService.ts:13-19` — `ProbeResult` interface; all probe functions return it; test 1 passes
7	Probe results are persisted to Supabase via `HealthCheckModel.create()`	VERIFIED	`healthProbeService.ts:219-225` — `await HealthCheckModel.create({...})` inside post-probe loop; test 2 passes
8	A single probe failure does not prevent other probes from running	VERIFIED	`healthProbeService.ts:198` — `Promise.allSettled()` + individual try/catch on persist; test 3 passes
9	LLM probe uses cheapest model (`claude-haiku-4-5`) with `max_tokens 5`	VERIFIED	`healthProbeService.ts:63-66` — `model: 'claude-haiku-4-5', max_tokens: 5`
10	Supabase probe uses `getPostgresPool().query('SELECT 1')`, not PostgREST client	VERIFIED	`healthProbeService.ts:105-106` — `const pool = getPostgresPool(); await pool.query('SELECT 1')`; test 5 passes
11	An alert email is sent when a probe returns 'degraded' or 'down'; deduplication prevents duplicate emails within cooldown	VERIFIED	`alertService.ts:103-143` — `evaluateAndAlert()` checks `findRecentByService()` before creating row and sending email; tests 2-4 pass
12	Alert recipient is read from `process.env.EMAIL_WEEKLY_RECIPIENT`, never hardcoded in runtime logic	VERIFIED	`alertService.ts:43` — `const recipient = process.env['EMAIL_WEEKLY_RECIPIENT']`; no hardcoded address in runtime path; test 5 passes
13	`runHealthProbes` Cloud Function export runs on 'every 5 minutes' schedule, separate from `processDocumentJobs`	VERIFIED	`index.ts:340-363` — `export const runHealthProbes = onSchedule({ schedule: 'every 5 minutes', ... })` — separate export
14	`runRetentionCleanup` deletes from `service_health_checks`, `alert_events`, and `document_processing_events` older than 30 days on schedule	VERIFIED	`index.ts:366-390` — `schedule: 'every monday 02:00'`; `Promise.all([HealthCheckModel.deleteOlderThan(30), AlertEventModel.deleteOlderThan(30), deleteProcessingEventsOlderThan(30)])`

Score: 14/14 truths verified

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
ANLY-01	02-01	Document processing events persist to Supabase at write time	SATISFIED	`analyticsService.ts` writes to `document_processing_events` via Supabase on each `recordProcessingEvent()` call
ANLY-03	02-01	Analytics instrumentation is non-blocking (fire-and-forget)	SATISFIED	`recordProcessingEvent()` return type is `void`; uses `void supabase...insert(...).then(...)` — no `await`; test 2 verifies return is `undefined`
HLTH-02	02-02	Each health probe makes a real authenticated API call	SATISFIED	`healthProbeService.ts` — Document AI calls `client.listProcessors()`, LLM calls `client.messages.create()`, Supabase calls `pool.query('SELECT 1')`, Firebase calls `admin.auth().verifyIdToken()`
HLTH-04	02-02	Health probe results persist to Supabase	SATISFIED	`healthProbeService.ts:219-225` — `HealthCheckModel.create()` called for every probe result
ALRT-01	02-03	Admin receives email alert when a service goes down or degrades	SATISFIED	`alertService.ts` — `sendAlertEmail()` called after `AlertEventModel.create()` for any non-healthy probe status
ALRT-02	02-03	Alert deduplication prevents repeat emails within cooldown period	SATISFIED	`alertService.ts:113-128` — `AlertEventModel.findRecentByService()` gates both row creation and email; test 4 verifies suppression
ALRT-04	02-03	Alert recipient stored as configuration, not hardcoded	SATISFIED	`alertService.ts:43` — `process.env['EMAIL_WEEKLY_RECIPIENT']` with no hardcoded default; service skips email if env var missing
HLTH-03	02-04	Health probes run on a scheduled interval, separate from document processing	SATISFIED	`index.ts:340-363` — `export const runHealthProbes = onSchedule({ schedule: 'every 5 minutes' })` — distinct export from `processDocumentJobs`
INFR-03	02-04	30-day rolling data retention cleanup runs on schedule	SATISFIED	`index.ts:366-390` — `export const runRetentionCleanup = onSchedule({ schedule: 'every monday 02:00' })` — deletes from all 3 monitoring tables

Orphaned requirements check: Requirements INFR-01 and INFR-04 are mapped to Phase 1 in REQUIREMENTS.md and are not claimed by any Phase 2 plan — correctly out of scope. HLTH-01, ANLY-02, INFR-02, ALRT-03 are mapped to Phase 3/4 — correctly out of scope.

All 9 Phase 2 requirement IDs (HLTH-02, HLTH-03, HLTH-04, ALRT-01, ALRT-02, ALRT-04, ANLY-01, ANLY-03, INFR-03) are accounted for with implementation evidence.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
`backend/src/index.ts`	225	`defineString('EMAIL_WEEKLY_RECIPIENT', { default: 'jpressnell@bluepointcapital.com' })`	Info	Personal email address as Firebase `defineString` deployment default. `emailWeeklyRecipient` variable is defined but never passed to any function or included in any secrets array — it is effectively unused. The runtime `alertService.ts` reads `process.env['EMAIL_WEEKLY_RECIPIENT']` correctly with no hardcoded default. Not an ALRT-04 violation (the `defineString` default is deployment infrastructure config, not source-code-hardcoded logic). Recommend removing the personal email from this default or replacing with a placeholder in a follow-up.

No blockers. No stubs. No placeholder implementations found.

TypeScript Compilation

npx tsc --noEmit — exit 0 (no output, no errors)

All new files compile cleanly with no TypeScript errors.

Test Results

Test Files  3 passed (3)
     Tests  23 passed (23)
  Duration  924ms

All 23 unit tests across analyticsService.test.ts, healthProbeService.test.ts, and alertService.test.ts pass.

Human Verification Required

1. Live Firebase Deployment — Health Probe Execution

Test: Deploy to Firebase and wait for a runHealthProbes trigger (5-minute schedule). Check Firebase Cloud Logging for healthProbeService: all probes complete log entry and verify 4 new rows in service_health_checks table. Expected: 4 rows inserted, all with real latency values. document_ai and firebase_auth probes return either healthy or degraded (not a connection failure). Why human: Cannot run Firebase scheduled functions locally; requires live GCP credentials and deployed infrastructure.

2. Alert Email Delivery — End-to-End

Test: Temporarily set ANTHROPIC_API_KEY to an invalid value and trigger runHealthProbes. Verify an email arrives at the EMAIL_WEEKLY_RECIPIENT address with subject [CIM Summary] Alert: llm_api — service_down. Expected: Email received within 5 minutes of probe run. Second probe cycle within 60 minutes should NOT send a duplicate email. Why human: SMTP delivery requires live credentials and network routing; deduplication cooldown requires real-time waiting.

3. Retention Cleanup — Data Deletion Verification

Test: Insert rows into document_processing_events, service_health_checks, and alert_events with created_at older than 30 days, then trigger runRetentionCleanup manually. Verify old rows are deleted and recent rows remain. Expected: Only rows older than 30 days deleted; row counts logged accurately. Why human: Requires live Supabase access and insertion of backdated test data.

Gaps Summary

None. All must-haves verified. Phase goal achieved.
