## Deep review focus areas

### Auth flow ({{AUTH}})
- Token storage: is `flutter_secure_storage` used for ALL tokens?
- Token refresh: is refresh handled atomically (no race condition)?
- Session expiry: does the app handle 401 gracefully without data loss?
- Certificate pinning: configured and tested?

### Data at rest
- SQLite/Hive encryption: sensitive DBs encrypted?
- Cache poisoning: cached API responses validated before use?
- Keychain/Keystore usage for cryptographic keys

### Network security
- All endpoints HTTPS — any http:// URLs?
- Certificate validation — any `badCertificateCallback: true`?
- Sensitive data in URL params/query strings?
- Request/response logging in production? (must be off)

### Code injection risks
- Dynamic code execution patterns
- WebView usage — JavaScript interface security
- Deep link parameter validation (no path traversal)
