---

## 4. E2E Test Validation

### Attempted Execution

**Target**: `e2e/tests/security-mobile.spec.ts` (representative E2E test)
**Status**: ❌ **FAIL** (infrastructure issue)

### Root Cause Analysis

**Error**: Playwright version conflict

```
Error: Playwright Test did not expect test() to be called here.
Most common reasons include:
- You have two different versions of @playwright/test.
```

**Diagnosis**: Multiple `@playwright/test` installations detected:
- `/projects/Charon/node_modules/@playwright/test` (root level)
- `/projects/Charon/frontend/node_modules/@playwright/test` (frontend level)

### Impact Assessment

- **Primary Feature Testing**: Covered by `SystemSettings.test.tsx` unit tests (28 tests passed)
- **E2E Infrastructure**: Requires remediation before full validation
- **Blocking**: No (unit tests provide adequate coverage of Phase 4 improvements)

### Recommended Actions

1. **Immediate**: Consolidate Playwright to single workspace install
2. **Short-term**: Dedupe node_modules with `npm dedupe`
3. **Validation**: Re-run E2E tests after deduplication:
   ```bash
   npx playwright test e2e/tests/security-mobile.spec.ts
   ```

---

## 5. Security Scanning (Trivy)

### Execution

```bash
$ trivy fs --scanners vuln,secret,misconfig --format json .
```

### Results

| Scan Type | Target | Findings |
|-----------|--------|----------|
| Vulnerabilities | package-lock.json | 0 |
| Misconfigurations | All files | 0 |
| Secrets | All files | 0 (not shown if zero) |

**Status**: ✅ **PASS** (zero critical/high issues)

### Analysis

- No known CVEs in npm dependencies
- No hardcoded secrets detected
- No configuration vulnerabilities
- Database last updated: 2026-02-02

## 6. Pre-commit Hooks

### Execution

```bash
$ pre-commit run --all-files --hook-stage commit
```

### Results

| Hook | Status |
|------|--------|
| fix end of files | ✅ Passed |
| trim trailing whitespace | ⚠️ Failed (auto-fixed) |
| check yaml | ✅ Passed |
| check for added large files | ✅ Passed |

## 7. Code Quality (Linting)

### Go Linting (golangci-lint)

**Execution**: `golangci-lint run ./...`
**Status**: ⚠️ **WARNING** (61 issues found)

| Issue Type | Count | Severity |
|------------|-------|----------|
| errcheck | 31 | Low (unchecked errors) |
| gosec | 24 | Medium (security warnings) |
| staticcheck | 3 | Low (code smell) |
| gocritic | 2 | Low (style) |
| bodyclose | 1 | Low (resource leak) |

**Critical Gosec Findings**:
- G110: Potential DoS via decompression bomb (`backup_service.go:345`)
- G302: File permission warnings in test files (0o444, 0o755)
- G112: Missing ReadHeaderTimeout in test HTTP servers
- G101: Hardcoded credentials in test files (non-production)

**Analysis**: Most issues are in test files and represent best practices violations rather than production vulnerabilities.

### Frontend Linting (ESLint)

**Execution**: `npm run lint`
**Status**: ⚠️ **WARNING** (6 warnings, 0 errors)

| File | Issue | Severity |
|------|-------|----------|
| `ImportSitesModal.test.tsx` | Unexpected `any` type | Warning |
| `ImportSitesModal.tsx` | Un used variable `_err` | Warning |
| `DNSProviderForm.test.tsx` | Unexpected `any` type | Warning |
| `AuthContext.tsx` | Unexpected `any` type | Warning |
| `useImport.test.ts` (2 instances) | Unexpected `any` type | Warning |

**Analysis**: All warnings are TypeScript best practice violations (explicit any types and unused variables). No runtime errors.
