## Security Issues

### FRE-454 - Auth Integration ✅ APPROVED

**Date Identified**: 2026-03-24
**Date Completed**: 2026-03-25
**Status**: APPROVED - Production Ready

**Previously Identified Issues (All Fixed):**
1. ✅ Weak ID generation using `Math.random()` → Fixed with `crypto.randomUUID()`
2. ✅ Missing security headers → Implemented in trpc.ts
3. ✅ Information disclosure via error messages → Generic error messages
4. ✅ JWT token generation missing → Now returned from signIn/signUp

**Security Controls Verified:**
- HMAC-SHA256 signature verification ✓
