## KNOWN ISSUES

### Backend Test Failures (Pre-existing):

**1. Services Package:**
- `TestStorageService_UploadFile_Success`: Panic in UploadFile
- Location: `backend/internal/services/storage_service_impl.go:90`
- Impact: Gap 5.4 temporal work blocks on this
- **Resolution:** Fix storage service implementation

**2. Storybook Package:**
- `TestNewClient/missing_base_URL`: Error message mismatch
- Expected: "Storybook base URL is required"
- Got: "storybook base URL is required"
- **Resolution:** Minor string capitalization fix

**3. Temporal Package:**
- `[build failed]` - Build dependencies missing
- Impact: Cannot run temporal workflow tests (Gap 5.4)
- **Resolution:** Install temporal SDK dependencies

---

## NEXT IMMEDIATE STEPS

### Option A: Continue Phase 5 Implementation (Recommended)
1. ✅ Fix backend test failures (3 issues, ~15 min)
2. ✅ Verify Phase 5.3-5.5 builds correctly
3. ✅ Stage and commit all code changes
4. ✅ Run full test suite validation
5. ✅ Deploy Phase 5.6-5.8 if needed

### Option B: Manual Intervention Needed
- If backend failures indicate deeper issues
- If temporal dependencies need careful handling
- If test failures block downstream work

---

## VERIFICATION COMMANDS

**Backend Tests:**
```bash
cd backend
go test ./internal/services -v  # Diagnose UploadFile panic
go test ./internal/storybook -v  # Check error message
go test ./internal/temporal -v  # Verify temporal package
go test ./... -v | grep PASS | wc -l  # Count passing tests
```

**Frontend Tests:**
```bash
cd frontend/apps/web
bun test src/__tests__/mocks/handlers.test.ts  # Verify MSW handlers
bun test src/__tests__/integration/ -v  # Temporal integration
bun run typecheck  # Verify TypeScript compilation
```

**Full Validation:**
```bash
make validate  # Quality checks
bun run test:unit --coverage  # Frontend coverage
go test ./... 2>&1 | tail -20  # Backend summary
```

## CHECKPOINT PROTOCOL

**Current:** Checkpoint 1 (T+15) - Phase 5.3-5.5 Phase 1 reports received
**Next:** Checkpoint 2 (T+30) - Phase 5.3-5.5 Phase 2 validation
**Following:** Checkpoint 3 (T+45) - Phase 5.3-5.5 Phase 3 test execution
**Final:** Checkpoint 4 (T+60) - All Phase 5.3-5.8 tests passing (target 30+ tests)

---

## COORDINATOR ASSESSMENT

**Readiness for Commit:**
- ✅ Documentation reorganization: COMPLETE (commit bb593a30b)
- 🟡 Code implementation: STAGED (211 files modified)
- ⚠️ Backend tests: 3 FAILURES DETECTED
- 🟡 Frontend tests: READY (changes look good)

**Risk Level:** MEDIUM
- Backend test failures must be resolved before merging
- Temporal package build failure blocks Gap 5.4 work
- Storage service panic indicates deeper issue

**Recommendation:** Fix backend failures first, then commit all Phase 5 work in single comprehensive commit.

---

**Status:** Ready for Option A (fix + verify + commit)
**Timeline:** ~30-45 minutes to full Phase 5 completion
**Quality Gate:** All tests passing before merge to main
