# Security Headers Verification Report

**Subtask:** subtask-2-1
**Date:** 2026-01-25
**Status:** Configuration Verified ✅

## Automated Verification Results

### ✅ Configuration File Analysis

All required security headers are correctly configured in `next.config.ts`:

#### 1. Content-Security-Policy ✅
- **Location:** Lines 46-58
- **Status:** FOUND
- **Directives Validated:**
  - ✓ `default-src 'self'` - Baseline security
  - ✓ `script-src 'self' 'unsafe-inline' 'unsafe-eval'` - Allows Next.js hydration
  - ✓ `style-src 'self' 'unsafe-inline' https://fonts.googleapis.com` - Allows Tailwind & Google Fonts
  - ✓ `font-src 'self' https://fonts.gstatic.com data:` - Google Fonts support
  - ✓ `img-src 'self' data: blob: https://mxadgucxhmstlzsbgmoz.supabase.co` - Supabase images
  - ✓ `connect-src 'self' https://mxadgucxhmstlzsbgmoz.supabase.co` - Supabase API
  - ✓ `frame-ancestors 'self'` - Prevents clickjacking
  - ✓ `base-uri 'self'` - Restricts base tag
  - ✓ `form-action 'self'` - Form submission restrictions

#### 2. Strict-Transport-Security ✅
- **Location:** Lines 60-62
- **Status:** FOUND
- **Value:** `max-age=31536000; includeSubDomains; preload`
- **Validation:**
  - ✓ max-age=31536000 (1 year)
  - ✓ includeSubDomains directive
  - ✓ preload directive

#### 3. Referrer-Policy ✅
- **Location:** Lines 64-66
- **Status:** FOUND
- **Value:** `strict-origin-when-cross-origin`
- **Validation:**
  - ✓ Correct policy for privacy and functionality balance

#### 4. Permissions-Policy ✅
- **Location:** Lines 68-70
- **Status:** FOUND
- **Value:** `geolocation=(), microphone=(), camera=(), payment=(), usb=()`
- **Validation:**
  - ✓ All sensitive features properly restricted

### ✅ Syntax Validation

- TypeScript compilation: ✅ PASSED (no errors)
- Configuration structure: ✅ VALID
- Headers array format: ✅ CORRECT

## Manual Verification Required

Due to environment constraints in the worktree, the following manual steps are required to complete the verification:

### Step 1: Start Development Server

```bash
npm run dev
```

Wait for the message: `Ready on http://localhost:3000`

### Step 2: Check Headers via curl

```bash
curl -I http://localhost:3000
```

**Expected Output:**
```
HTTP/1.1 200 OK
Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com data:; img-src 'self' data: blob: https://mxadgucxhmstlzsbgmoz.supabase.co; connect-src 'self' https://mxadgucxhmstlzsbgmoz.supabase.co; frame-ancestors 'self'; base-uri 'self'; form-action 'self'
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
Referrer-Policy: strict-origin-when-cross-origin
Permissions-Policy: geolocation=(), microphone=(), camera=(), payment=(), usb=()
...
```

### Step 3: Browser DevTools Verification

1. Open http://localhost:3000 in browser
2. Open DevTools (F12)
3. Navigate to **Network** tab
4. Refresh the page
5. Click on the document request (localhost)
6. Check **Response Headers** section

**Verify these headers are present:**
- ✅ content-security-policy
- ✅ strict-transport-security
- ✅ referrer-policy
- ✅ permissions-policy

### Step 4: Console CSP Violation Check

1. Stay in DevTools
2. Navigate to **Console** tab
3. Check for any CSP violation errors

**Expected:** No CSP violations should appear

### Step 5: Functionality Testing

Test that external resources load correctly:

- ✅ Google Fonts render properly
- ✅ Supabase images load
- ✅ Navigation works
- ✅ JSON-LD structured data renders (view page source)

## Summary

### Automated Verification: ✅ PASSED
- All 4 security headers configured correctly
- Syntax is valid
- Configuration follows Next.js best practices

### Manual Verification: ⏳ PENDING
- Dev server start required
- HTTP response header check required
- Browser functionality test required
- CSP violation check required

## Next Steps

1. Complete manual verification steps above
2. If all manual checks pass, mark subtask-2-1 as completed
3. Proceed to subtask-2-2 (application functionality testing)
4. Create git commit for verification completion

## Notes

- The verification script (`verify-headers.mjs`) can be run anytime with: `node verify-headers.mjs`
- All headers are configured in the `headers()` function for the `/:path*` route
- Headers will apply to all pages in the application
