Database Permissions & Milestone Tracker Hardening
Robust Query Isolation: Wrapped database requests within the Milestones Modal in selective catch blocks. If a transient error or permission restriction occurs while querying the matchmaking arena, the modal will gracefully isolate the failure and continue loading all other user-specific milestones and study stats.
Security Configuration Alignment: Refined Firestore Security Rules to permit authenticated read operations on the arena_matches collection, resolving permission conflicts when retrieving competitive history.
2. Real-Time Connection Stability
WebSocket Heartbeat Mechanism: Integrated a server-side active ping-pong check (set at 30-second intervals) on the /live WebSocket route. Stale or unresponsive client connections are automatically pruned, keeping server memory light and ensuring high-quality, continuous voice streaming for active tutor sessions.
3. Server & Schema Verification
Session Rules Hardening: Synchronized document structural rules with schema validation functions to guarantee that only properly formatted session transcripts, quiz scores, and category tags are written to individual user profiles.
Successful Production Build: Verified full-system compilation including Vite bundle optimizations and server entry-point compilation via esbuild, ensuring zero runtime import errors.
