Phase 01 modifies persistence and HTTP handler logic — no new components rendering dynamic data are introduced. Existing data flow (WebhookHandler → UpdateEvent → SQLite → GetUpdates → UpdatesHandler → React SPA) is unchanged in structure. --- ### Behavioral Spot-Checks | Behavior | Check | Result | Status | |-----------------------------------------------|------------------------------------------------|-------------------------------|----------| | No INSERT OR REPLACE remains | grep -c "INSERT OR REPLACE INTO updates" | 0 | PASS | | PRAGMA foreign_keys present once | grep -c "PRAGMA foreign_keys = ON" | 1 | PASS | | UPSERT present once | grep -c "ON CONFLICT(image) DO UPDATE SET" | 1 | PASS | | maxBodyBytes defined and used (5 occurrences) | grep -c "maxBodyBytes" | 5 | PASS | | MaxBytesReader applied in 4 handler paths | grep -c "MaxBytesReader" | 4 | PASS | | errors.As used for 413 detection (4 paths) | grep -c "errors.As" | 4 | PASS | | 413 returned in 4 handler paths | grep -c "StatusRequestEntityTooLarge" | 4 | PASS | | All 33 tests pass | go test ./pkg/diunwebhook/ (with Go binary) | PASS (33/33, coverage 63.8%) | PASS | | t.Fatalf used for test setup (27 occurrences) | grep -c "t\.Fatalf" | 27 | PASS | --- ### Requirements Coverage All four requirement IDs declared across both plans are cross-referenced against REQUIREMENTS.md. | Requirement | Source Plan | Description | Status | Evidence | |-------------|-------------|----------------------------------------------------------------------------------------------|-----------|-------------------------------------------------------------------------------------| | DATA-01 | 01-01-PLAN | Webhook events use proper UPSERT preserving tag assignments on re-event | SATISFIED | ON CONFLICT(image) DO UPDATE SET at diunwebhook.go:122; TestUpdateEvent_PreservesTagOnUpsert passes | | DATA-02 | 01-01-PLAN | SQLite FK enforcement enabled (PRAGMA foreign_keys = ON) so tag deletion cascades | SATISFIED | PRAGMA at diunwebhook.go:68; TestDeleteTagHandler_CascadesAssignment passes | | DATA-03 | 01-02-PLAN | Webhook and API endpoints enforce 1MB body size limit, return 413 on oversized payload | SATISFIED | MaxBytesReader in 4 handler paths; 3 oversized-body tests all return 413 | | DATA-04 | 01-02-PLAN | Test error handling uses t.Fatal/t.Fatalf, test failures are never swallowed | SATISFIED | 27 t.Fatalf calls; zero silent `if err != nil { return }` patterns remain | **Orphaned requirements check:** REQUIREMENTS.md maps DATA-01, DATA-02, DATA-03, DATA-04 to Phase 1. All four are claimed by plans 01-01 and 01-02. No orphaned requirements. **Coverage:** 4/4 Phase 1 requirements satisfied. --- ### Anti-Patterns Found | File | Line | Pattern | Severity | Impact | |------|------|---------|----------|--------| | `pkg/diunwebhook/diunwebhook_test.go` | 359 | `diun.UpdateEvent(...)` with no error check in `TestDismissHandler_ReappearsAfterNewWebhook` | Info | The call at line 359 is a non-setup call (it is the action under test, not setup); the test proceeds to assert state, so a failure would surface via the assertions below. Not a silent swallow of setup failure. | No blocker or warning anti-patterns found. The single info item (line 359 unchecked call) is in `TestDismissHandler_ReappearsAfterNewWebhook` and is the test's subject action, not a setup call — the test assertions on lines 362-369 would catch a failure. --- ### Human Verification Required None. All phase 01 goals are verifiable programmatically via grep patterns and test execution. No UI, visual, or real-time behaviors were added in this phase. --- ### Gaps Summary No gaps. All 6 truths verified, all 4 artifacts substantive and wired, all 5 key links confirmed, all 4 requirements satisfied, full test suite passes (33/33), and no blocker anti-patterns found. --- ### Commit Traceability All commits documented in SUMMARYs are present in git history on `develop` branch: | Commit | Description | Plan | |-----------|----------------------------------------------------------------------|-------| | `7edbaad` | fix(01-01): replace INSERT OR REPLACE with UPSERT and enable FK enforcement | 01-01 | | `e2d388c` | test(01-01): add TestUpdateEvent_PreservesTagOnUpsert regression test | 01-01 | | `311e91d` | test(01-02): add failing tests for oversized body (413) - RED | 01-02 | | `98dfd76` | feat(01-02): add request body size limits (1MB) to webhook and tag handlers | 01-02 | | `7bdfc5f` | fix(01-02): replace silent test setup returns with t.Fatalf at 6 sites | 01-02 | --- _Verified: 2026-03-23T21:30:00Z_ _Verifier: Claude (gsd-verifier)_
