PostgreSQL End-to-End Connectivity + +**Test:** Start the app with a real PostgreSQL instance (e.g., `docker compose --profile postgres up -d`), set `DATABASE_URL=postgres://diun:diun@localhost:5432/diundashboard?sslmode=disable`, send a webhook POST, then fetch `/api/updates` +**Expected:** App logs "Using PostgreSQL database", webhook stores data in Postgres, GET /api/updates returns the event with correct fields, tags and acknowledgments work identically to SQLite +**Why human:** No PostgreSQL instance available in automated environment + +#### 2. Docker Compose postgres profile end-to-end + +**Test:** Run `docker compose --profile postgres up` with a `.env` containing `DATABASE_URL=postgres://diun:diun@postgres:5432/diundashboard?sslmode=disable`, confirm app waits for postgres health check, connects, and serves the dashboard +**Expected:** postgres service starts, pg_isready passes, app container starts after it, dashboard loads in browser +**Why human:** Full compose stack requires running Docker daemon and inter-container networking + +#### 3. SQLite backward-compatibility upgrade + +**Test:** Take a `diun.db` file created by a pre-Phase-3 binary (with existing rows in updates, tags, tag_assignments), start the new binary pointing at it (DATABASE_URL unset, DB_PATH set to that file) +**Expected:** golang-migrate detects schema is already at migration version 1 (ErrNoChange, no-op), all existing rows appear in the dashboard without any manual schema changes +**Why human:** Requires a pre-existing SQLite database from a previous binary version + +### Gaps Summary + +One gap found: `github.com/jackc/pgx/v5` is marked `// indirect` in `go.mod` even though `cmd/diunwebhook/main.go` directly imports `_ "github.com/jackc/pgx/v5/stdlib"`. Running `go mod tidy` moves it to the direct require block. This is a module hygiene issue — the binary compiles and runs correctly — but it violates the DB-01 plan acceptance criterion ("pgx/v5 is in go.mod as a direct dependency") and will cause confusion for anyone reading go.mod expecting to understand the project's direct dependencies. + +**Fix:** Run `go mod tidy` in the project root. This requires no code changes and takes under 1 second. + +--- + +_Verified: 2026-03-24T10:00:00Z_ +_Verifier: Claude (gsd-verifier)_
