- Upgrade Fastify 4→5 with all plugins (@fastify/websocket 11, cors 11, sensible 6) - Migrate all SSE endpoints to WebSocket + FCM push (mitra chat requests, customer pairing status) - Add flutter_local_notifications for foreground push notifications with sound - Add splash screen to both apps (hide auth loading flash) - Introduce constants/enums across entire codebase (no raw string literals) - Move price tiers from hardcoded array to app_config DB (data-driven, includes 1-min test tier) - Add session ownership validation on all shared chat routes - Add ownership checks on endSession, respondToExtension, requestExtension - Fix session timer: auto-complete expired/stale sessions on server restart - Add 5-min grace period for abandoned closing sessions - Fix extension flow: proper session_resumed handling, clearExtensionRequest, closure grace timer cleanup - Fix chat screens: ConnectChat in initState, session status check on connect - Fix customer expired view: 5-min countdown, closure state priority over expired state - Fix mitra extension UI: loading spinner, disable buttons, handle EXTENSION_RESOLVED error - Fix GoRouter navigation consistency (no more Navigator.pushNamed) - Fix goodbye view keyboard overflow (SingleChildScrollView) - Add active session card on customer home screen with refresh on navigate back - Fix PricingBottomSheet extension mode (RequestExtension instead of new pairing) - Send session_resumed to both parties on extension accept Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
