🛡️ 1. Security & Privacy Hardening (Phases 1–3 Complete)

• BOLA / IDOR Defense: Enforced strict conversation participant checks on all read/write chat operations (403 Forbidden on unauthorized access).
• Anti-Trilateration GPS Privacy: Sealed Discovery Feed (/feed) and Profile endpoints to return only radial distances (distance_km), completely stripping raw coordinates (lat/lon).
• Hardware Screen Protection: Enabled native Android FLAG_SECURE to block screenshots, malicious screen recordings, and recent-app task switcher snapshots.
• Encrypted Storage: Migrated sensitive auth and user credentials to hardware-backed Keystore/Keychain via FlutterSecureStorage.
• Network Restraints (Anti-MitM): Restricted network configuration to reject unencrypted HTTP traffic and untrusted proxy certificates.
• Release Obfuscation: Enabled R8 / ProGuard shrinking and class repackaging for hardened binary security.

🚀 2. O2O "Date Spot Radar" & Deep-Link Navigation

• Fast Multi-Tier Spot Engine: Fast commercial venue scanning (Cafes, Restaurants, Lounges, Chai Spots) with a strict 50 km hard ceiling.
• Zero-Drift Navigation: Integrated coordinate-locked map intent linking to open Google Maps directly on exact GPS markers.
• Native In-Chat Suggestion Bubbles: Suggest verified spots inside chat via rich interactive cards without triggering Safe Bridge link-protection filters.

⚡ 3. Real-Time Chat & Backend Performance

• DDoS & Spam Defense: Implemented multi-tier sliding-window rate limiting on messaging, feed swiping, and location endpoints.
• Cryptographic WebSocket Handshake: Secured real-time chat with JWT token signature verification and automatic stale-session cleanup.
• Database Query Acceleration: Added composite indexes across messages, users, and matches tables, reducing query latency.
• Deep-Link Lifecycle Fixes: Resolved route hijacking on notification clicks to ensure seamless, direct navigation into active chat threads.

🧪 Automated QA & Test Metrics

• Backend: 40+ automated security & unit tests passed (pytest)
• Mobile: 0 errors / 0 warnings (flutter analyze)
