Phase 01: Data Foundation Verification Report

Phase Goal: The database schema for monitoring exists and the existing Supabase connection is the only data infrastructure used Verified: 2026-02-24T13:00:00Z Status: human_needed Re-verification: Yes — after ROADMAP success criteria updated to match finalized naming

Goal Achievement

Observable Truths (from ROADMAP Success Criteria)

#	Truth	Status	Evidence
1	service_health_checks and alert_events tables exist in Supabase with indexes on created_at	VERIFIED	Migration 012_create_monitoring_tables.sql creates both tables; idx_service_health_checks_created_at (line 24) and idx_alert_events_created_at (line 52) present. Live DB execution requires human.
2	All new tables use the existing Supabase client from config/supabase.ts — no new database connections added	VERIFIED	Both models import getSupabaseServiceClient from '../config/supabase' (line 1 of each); called per-method, not at module level; no new Pool, new Client, or createClient in either file
3	AlertEventModel.ts exists and its CRUD methods can be called in isolation without errors	VERIFIED	backend/src/models/AlertEventModel.ts exists (343 lines, 6 static methods); 19 unit tests all pass
4	Migration SQL can be run against the live Supabase instance and produces the expected schema	HUMAN NEEDED	SQL is syntactically valid and follows existing migration patterns; live execution cannot be verified programmatically

Score: 3/4 success criteria fully verified (1 human-needed)

Required Artifacts

Artifact	Expected	Status	Details
backend/src/models/migrations/012_create_monitoring_tables.sql	DDL for monitoring tables	VERIFIED	65 lines; 2 tables with CHECK constraints, JSONB columns, 5 indexes total, RLS enabled on both
backend/src/models/HealthCheckModel.ts	CRUD for service_health_checks	VERIFIED	219 lines; 4 static methods; imports getSupabaseServiceClient and logger; exports HealthCheckModel, ServiceHealthCheck, CreateHealthCheckData
backend/src/models/AlertEventModel.ts	CRUD for alert_events	VERIFIED	343 lines; 6 static methods; imports getSupabaseServiceClient and logger; exports AlertEventModel, AlertEvent, CreateAlertEventData
backend/src/models/index.ts	Barrel exports for new models	VERIFIED	Both models and all 4 types exported (lines 7-8, 11-12); existing exports unchanged

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
INFR-01	01-01-PLAN, 01-02-PLAN	Database migrations create service_health_checks and alert_events tables with indexes on created_at	SATISFIED	idx_service_health_checks_created_at and idx_alert_events_created_at in migration (lines 24, 52); 33 tests pass; marked complete in REQUIREMENTS.md
INFR-04	01-01-PLAN, 01-02-PLAN	Analytics writes use existing Supabase connection, no new database infrastructure	SATISFIED	Both models call getSupabaseServiceClient() per-method; no new Pool, new Client, or createClient in new files; test mocks confirm the pattern; marked complete in REQUIREMENTS.md

No orphaned requirements. REQUIREMENTS.md traceability maps only INFR-01 and INFR-04 to Phase 1, both accounted for.

Test Results

Test Files  2 passed (2)
     Tests  33 passed (33)
  Duration  1.19s

All 33 tests pass. No regressions from initial verification.

• HealthCheckModel: 14 tests covering create (valid/minimal/probe_details), validation (empty name, invalid status), Supabase error + error logging, findLatestByService (found/PGRST116 null), findAll (default limit/filtered/custom limit), deleteOlderThan (date calc/count)
• AlertEventModel: 19 tests covering create (valid/default status/explicit status/JSONB details), validation (empty name, invalid alert_type, invalid status), Supabase error, findActive (all/filtered/empty), acknowledge/resolve (success/PGRST116 not-found), findRecentByService (found/null), deleteOlderThan

Human Verification Required

1. Migration Execution Against Live Supabase

Test: Run backend/src/models/migrations/012_create_monitoring_tables.sql against the live Supabase instance via the SQL editor or migration runner Expected: Both service_health_checks and alert_events tables created; all columns, CHECK constraints, JSONB columns, 5 indexes, and RLS appear when inspected in the Supabase table editor Why human: Cannot execute SQL against the live database from this verification environment

Re-Verification Summary

Both gaps from the initial verification are now closed. The gaps were documentation alignment issues — the ROADMAP success criteria contained stale names from an earlier naming pass that did not survive into the finalized plan and implementation. The ROADMAP has been updated to match:

• SC#1 now reads service_health_checks and alert_events (matching migration and models)
• SC#3 now reads AlertEventModel.ts (matching the implemented file)

The implementation was correct throughout both verifications. All automated checks pass. The one remaining item requiring human action is executing the migration SQL against the live Supabase instance — this was always a human-only step and is not a gap.

Phase goal is achieved: The database schema for monitoring exists in the migration file and model layer, and the existing Supabase connection is the only data infrastructure used.
