## Coverage Validation

### Backend Coverage

**Status:** ✅ PASS - Below Internal Standard (Target: 85%)

```
Total Coverage: 82.2%
Threshold: 85% (not enforced for backend)
Status: Acceptable but below best practice
```

**Coverage by Package:**
- High Coverage (≥90%): 11 packages
- Good Coverage (80-89%): 10 packages
- Needs Attention (<80%): 4 packages

**Packages Below 85%:**
1. `internal/api/handlers`: 81.9%
2. `internal/crowdsec`: 84.0%
3. `internal/services`: 80.7%
4. `pkg/dnsprovider/builtin`: 30.4%

**Note:** Backend coverage is acceptable for current phase but should be improved in future iterations.

### Frontend Coverage

**Status:** ❌ FAIL - Below Mandatory Threshold

```
Total Coverage: 84.69%
Threshold: 85.00%
Gap: -0.31%
Status: BLOCKING ISSUE
```

**Critical Low-Coverage Areas:**
- `src/api/auditLogs.ts`: 0% (not covered)
- `src/api/encryption.ts`: 0% (not covered)
- `src/api/plugins.ts`: 0% (not covered)
- `src/api/securityHeaders.ts`: 10% (minimal coverage)
- `src/components/PermissionsPolicyBuilder.tsx`: 32.81%
- `src/hooks/useAuditLogs.ts`: 42.85%

**Recommendation:** Add tests for the uncovered API modules to reach the 85% threshold.

---

## Type Safety Validation

### TypeScript Check

**Status:** ✅ PASS

```
Command: cd frontend && npm run type-check
Result: tsc --noEmit completed successfully
Exit Code: 0
```

No TypeScript type errors detected.

### Go Compilation

**Status:** ✅ PASS

```
Command: cd backend && go build ./...
Result: Compilation successful
Exit Code: 0
```

All Go packages compile without errors.

---

## Pre-commit Validation

**Status:** ⚠️ NEEDS ATTENTION

```
Command: Lint: Pre-commit (All Files) (VS Code Task)
Result: Failed (trailing whitespace)
Exit Code: 2
```

**Failures:**
1. **Trailing Whitespace:** `docs/plans/current_spec.md`
   - Status: Auto-fixed by pre-commit hook
   - Action Required: Review and commit the fix

**Passed Checks:**
- check yaml
- check for added large files
- dockerfile validation
- Go Vet
- Prevent large files not tracked by LFS
- Prevent committing CodeQL DB artifacts
- Prevent committing data/backups files
- Frontend TypeScript Check
- Frontend Lint (Fix)

**Note:** The trailing whitespace issue was automatically fixed by the pre-commit hook. The file should be reviewed and committed.

**Status:** ✅ PASS

```
Command: Security: CodeQL Go Scan (CI-Aligned) (VS Code Task)
Result: Scan completed successfully

## Recommendation

**Status:** ⚠️ NEEDS WORK

### Blocking Issues

The following issues **MUST** be resolved before Phase 7 can be marked complete:

1. **Frontend Coverage:** Increase coverage from 84.69% to ≥85.00%
   - Add tests for uncovered API modules
   - Target: `auditLogs.ts`, `encryption.ts`, or `plugins.ts`
   - Estimated effort: 1-2 test files

### Non-blocking Issues

2. **Pre-commit Fix:** Commit the trailing whitespace fix
   - File: `docs/plans/current_spec.md`
   - Action: `git add` and commit

3. **Backend Coverage:** Consider improving backend coverage in future iterations
   - Current: 82.2%
   - Target: 85%
   - This is advisory only and does not block completion

---

## Next Steps

1. **Frontend Dev:** Add tests to reach 85% frontend coverage threshold
2. **Commit:** Review and commit pre-commit auto-fixes
3. **Re-run:** Execute "Test: Frontend with Coverage" task to verify ≥85%
4. **Re-validate:** QA_Security to re-run validation after fixes
