### 1.3 Type Safety Check ✅

**Command**: `cd frontend && npm run type-check` (VS Code Task: "Lint: TypeScript Check")
**Status**: ✅ PASS
**TypeScript Errors**: 0

---

## 2. Pre-commit Hooks ⚠️

**Command**: `pre-commit run --all-files`
**Status**: ⚠️ PASS WITH NOTES

**Hooks Results**:
- ✅ fix end of files
- ✅ trim trailing whitespace
- ✅ check yaml
- ✅ check for added large files
- ✅ dockerfile validation
- ✅ Go Vet
- ⚠️ Check .version matches latest Git tag - **Expected Failure** (version 0.11.2 vs tag v0.14.1)
- ✅ Prevent large files that are not tracked by LFS
- ✅ Prevent committing CodeQL DB artifacts
- ✅ Prevent committing data/backups files
- ✅ Frontend TypeScript Check
- ✅ Frontend Lint (Fix)

**Note**: Version mismatch is a pre-existing condition unrelated to current changes.

---

## 3. Code Quality ✅

### 3.1 Backend Compilation

**Command**: `cd backend && go build ./...`
**Status**: ✅ PASS - Compiles without errors

### 3.2 Console.log Audit

**Status**: ⚠️ EXISTING (Pre-existing, non-critical)

**Existing console.log statements** (diagnostic/debugging for WebSocket connections):
- `frontend/src/components/LiveLogViewer.tsx:186` - WebSocket connected status
- `frontend/src/components/LiveLogViewer.tsx:198` - WebSocket disconnected status
- `frontend/src/context/AuthContext.tsx:73` - Auto-logout notification
- `frontend/src/api/logs.ts:137-225` - WebSocket diagnostic logging (7 occurrences)

**Assessment**: These are intentional diagnostic logs for WebSocket connection state, useful for debugging connection issues. **Not blocking.**

### 3.3 Commented-out Code

**Status**: ✅ PASS - No TODO/FIXME/HACK/XXX comments in frontend code

---

## 4. Security Scans ✅

### 4.1 Go Vulnerability Check

**Command**: `cd backend && go run golang.org/x/vuln/cmd/govulncheck@latest ./...` (VS Code Task: "Security: Go Vulnerability Check")
**Status**: ✅ PASS
**Result**: **No vulnerabilities found**

---

## 5. Functional Verification ✅

| 3 | paranoid | 100 | ✅ |

**Verified in**: `backend/internal/services/security_headers_service_test.go:21-73`

## 8. Issues Found

### Issue #1: Pre-existing Console.log Statements

**Severity**: 🟡 LOW (Pre-existing, diagnostic)
**Location**: `frontend/src/api/logs.ts`, `frontend/src/components/LiveLogViewer.tsx`, `frontend/src/context/AuthContext.tsx`
**Description**: 9 console.log statements for WebSocket connection diagnostics
**Impact**: None - diagnostic logging for debugging purposes
**Recommendation**: Consider converting to conditional debug logging or removing in future cleanup task

### Issue #2: Version Tag Mismatch

**Severity**: 🟡 LOW (Pre-existing)
**Location**: `.version` file
**Description**: `.version` (0.11.2) doesn't match latest Git tag (v0.14.1)
**Impact**: Pre-commit hook warning only
**Recommendation**: Update version file or create new tag as part of release process
