- `domains.ts`: 100%
- `featureFlags.ts`: 100%
- `logs.ts`: 100%
- `notifications.ts`: 100%
- `presets.ts`: 100%
- `proxyHosts.ts`: 91.3%
- `remoteServers.ts`: 100%
- `security.ts`: 100%
- `securityHeaders.ts`: 10% (new module, requires additional tests)
- `settings.ts`: 100%
- `setup.ts`: 100%
- `system.ts`: 84.61%
- `uptime.ts`: 100%
- `users.ts`: 100%
- `websocket.ts`: 100%

##### Components (80.64% coverage)

- Core components well-covered (80%+ on most)
- Notable: `CSPBuilder.tsx` at 93.9%
- Notable: `Layout.tsx` at 84.31%
- Notable: `LogViewer.tsx` at 93.04%
- `SecurityPolicyBuilder.tsx`: 32.81% (complex UI component)
- `ProxyHostForm.tsx`: 79.26%
- `SecurityProfileForm.tsx`: 57.89%

##### Pages (79.2% coverage)

- `SystemSettings.tsx`: 82.35%
- `UsersPage.tsx`: 78.37%

##### Utilities and Context (87.5%+)

- Hooks: 87.5%
- Context: 69.23%
- Utils: 37.5% (toast notification utilities)

#### Known Test Warnings

Multiple React `act()` warnings were observed during test execution. These are related to asynchronous state updates in:

- `InviteModal` component
- `SystemSettings` component
- `Tooltip` and `Select` components

**Impact:** Low - Tests pass successfully, warnings are informational about test structure improvements

**Recommendation:** Future enhancement to wrap async updates in `act()` for cleaner test output

---

## Step 2: TypeScript Type Check

### Execution Details

- **Command:** `npm run type-check`
- **Result:** ✅ **PASS**
- **Errors Found:** **0**

### Output

```
> charon-frontend@0.3.0 type-check
> tsc --noEmit
```

**Status:** TypeScript compilation successful with zero type errors.

---

## Step 3: Pre-commit Hooks Validation

### Execution Details

- **Command:** `pre-commit run --all-files`
- **Overall Result:** ⚠️ **PASS with Known Issue**

### Results by Hook

| Hook | Status | Notes |
|------|--------|-------|
| fix end of files | ✅ Passed | |
| trim trailing whitespace | ✅ Passed | |
| check yaml | ✅ Passed | |
| check for added large files | ✅ Passed | |
| dockerfile validation | ✅ Passed | |
| Go Vet | ✅ Passed | |
| Check .version matches latest Git tag | ❌ Failed | **Pre-existing issue** |
| Prevent large files not tracked by LFS | ✅ Passed | |
| Prevent committing CodeQL DB artifacts | ✅ Passed | |
| Prevent committing data/backups files | ✅ Passed | |
| Frontend TypeScript Check | ✅ Passed | |
| Frontend Lint (Fix) | ✅ Passed | |

### Known Issue: Version Tag Mismatch

**Issue:** `.version` file contains `0.14.1` while latest Git tag is `v1.0.0`

**Analysis:**

- This is a **pre-existing configuration issue**
- Not related to test coverage work
- Does not impact code quality or test results
- Likely related to project versioning strategy

**Recommendation:** Update `.version` file to `1.0.0` or create a new tag `v0.14.1` based on project versioning policy. This should be addressed in a separate task.

**Impact on Coverage Verification:** None - this is a version management issue unrelated to test quality

## Remaining Issues

### Critical Issues

**None** ✅

### Non-Critical Items for Future Enhancement

1. **React `act()` Warnings**
   - **Severity:** Low (informational)
   - **Location:** Multiple component tests
   - **Action:** Wrap async state updates in `act()` for cleaner test output
   - **Blocking:** No

2. **Version Tag Mismatch**
   - **Severity:** Low (configuration)
   - **Location:** `.version` file vs Git tags
   - **Action:** Synchronize version file with git tags
   - **Blocking:** No

3. **Coverage Opportunities**
   - `securityHeaders.ts`: 10% coverage (new module)
   - `SecurityPolicyBuilder.tsx`: 32.81% (complex UI)
   - `utils/toast.ts`: 37.5%
   - These are not blocking as overall coverage exceeds 85%

2. **Test Quality:** All 1174 tests pass with zero failures
3. **Type Safety:** Zero TypeScript errors
4. **Code Quality:** Pre-commit hooks pass (except 1 pre-existing version issue)

### Sign-Off

The frontend test suite provides comprehensive coverage across all critical paths:

- API layer: 92.19% coverage with full coverage on most modules

## Recommendations for Next Steps

1. **Immediate:** Merge the coverage improvements
2. **Short-term:** Address React `act()` warnings for cleaner test output
3. **Medium-term:** Resolve version file/tag synchronization
4. **Long-term:** Continue improving coverage on lower-coverage modules (optional)
