## CRITICAL FINDINGS - DEPLOYMENT BLOCKERS

### 🔴 BLOCKER #1: E2E Test Authentication Failure

**Severity**: CRITICAL
**Impact**: Complete E2E test suite blocked (2,551 tests could not run)

**Details**:
- Authentication setup test failed with 401 error: `{"error":"invalid credentials"}`
- Missing required environment variables: `E2E_TEST_EMAIL`, `E2E_TEST_PASSWORD`
- Container running on non-standard port (8787) with production-like configuration

**Evidence**:
```
Error: Login failed: 401 - {"error":"invalid credentials"}
1 failed: [setup] › tests/auth.setup.ts:26:1 › authenticate
2551 did not run
```

**Remediation**:
1. Add E2E test credentials to `.env` file
2. OR provision clean test database for automated test user creation
3. Ensure emergency reset endpoint returns JSON (not HTML)

**Status**: UNRESOLVED

### 🔴 BLOCKER #2: Docker Image High Severity Vulnerabilities

**Severity**: CRITICAL
**Impact**: 7 HIGH severity CVEs in base system libraries (GNU C Library)

**Vulnerability Summary**:
- 🔴 Critical: 0
- 🟠 **High: 7**
- 🟡 Medium: 20
- 🟢 Low: 2

**HIGH Severity Issues** (All "No fix available"):
1. CVE-2026-0861 (CVSS 8.4) - `libc-bin`/`libc6` - Buffer overflow in memalign
2. CVE-2025-13151 (CVSS 7.5) - `libtasn1-6` - Stack-based buffer overflow
3. CVE-2025-15281 (CVSS 7.5) - `libc-bin`/`libc6` - wordexp vulnerability (×2)
4. CVE-2026-0915 (CVSS 7.5) - `libc-bin`/`libc6` - getnetbyaddr vulnerability (×2)

**Verdict**: ❌ **FAILS** acceptance criteria (zero Critical/High required)

**Remediation Path**:
- Short-term: Risk acceptance for known CVEs + runtime mitigations
- Long-term: Upgrade base image when Debian security patches released

**Status**: UNRESOLVED

## PASSING RESULTS

### ✅ Backend Test Coverage

**Result**: **86.5%** (Target: 85%) ✅ Exceeds by 1.5%

**Validation**:
```bash
cd backend && go tool cover -func=coverage.txt | tail -1
# Output: total: (statements) 86.5%
```

**Notable**:
- `validator.go`: 100% (critical fix verified)
- `config.go`: 100%

---

### ✅ Type Safety Check

**Result**: Zero TypeScript errors ✅

```bash
cd frontend && npm run type-check
# Output: tsc --noEmit (no errors)
```

---

### ✅ Security: Trivy Filesystem Scan

**Result**: Zero vulnerabilities ✅

- Go modules: 0
- Frontend npm: 0
- Root npm: 0
- Secrets: 0

---

### ✅ Security: CodeQL Static Analysis

**Result**: Zero errors/warnings ✅

- **Go**: 318 files scanned, 0 errors, 0 warnings
- **JavaScript/TypeScript**: 318 files scanned, 0 errors, 0 warnings
- **Queries**: 88 security patterns checked (XSS, SQLi, Command Injection, SSRF, etc.)

---

## INCOMPLETE TESTS

### ⏸️ Frontend Unit Test Coverage

**Status**: INCOMPLETE
**Reason**: Test execution exceeded timeout (>2 minutes)

**Partial observations** showed high coverage:
- `src/components/ui`: Most files 100%
- `src/hooks`: 97.83%
- `src/pages`: 83.16%
- `src/utils`: 96.49%

**Recommendation**: Investigate test performance; run in isolated CI job with extended timeout

---

## ENVIRONMENT ANOMALIES

**Expected** (per compose file):
- Image: `ghcr.io/wikid82/charon:latest`
- Port: `8080:8080`

**Actual**:
- Image: `charon:local`
- Port: `8787:8080`
- Status: Unhealthy
- Context: Production-like deployment

**Action**: Document standard test environment setup; create dedicated E2E test compose config

---

## ACCEPTANCE CRITERIA REVIEW

| Criteria | Target | Actual | Status |
|----------|--------|--------|--------|
| E2E Tests Pass | All | 1/2553 | ❌ **FAIL** |
| Backend Coverage | ≥85% | 86.5% | ✅ **PASS** |
| Frontend Coverage | ≥85% | Unknown | ⏸️ **INCOMPLETE** |
| Type Errors | 0 | 0 | ✅ **PASS** |
| Trivy Critical/High | 0 | 0 | ✅ **PASS** |
| Docker Critical/High | 0 | 7 High | ❌ **FAIL** |
| CodeQL Errors | 0 | 0 | ✅ **PASS** |

**Overall Verdict**: ❌ **DEPLOYMENT BLOCKED**

---

## RECOMMENDATIONS

### Immediate (BLOCKING)

1. **E2E Environment**: Fix test credentials + standard port mapping + emergency endpoint JSON response
2. **Docker Security**: Risk acceptance meeting OR postpone until Debian patches available

### High Priority

3. **Frontend Tests**: Profile performance, add timeout monitoring
4. **Automation**: Add coverage/security scans to CI/CD

## QA SIGN-OFF

**Auditor**: QA_Security
**Date**: 2026-01-28
**Status**: ❌ **DEPLOYMENT NOT APPROVED**

**Blocking Issues**:
1. E2E authentication failure (2,551 tests blocked)
2. 7 HIGH severity vulnerabilities in Docker image

**Conditional Approval**: Requires:
- E2E authentication resolution
