 ### Fixes
 
+- Control UI/Talk: allow the OpenAI Realtime WebRTC offer endpoint through the Control UI CSP, configure browser sessions with explicit VAD/transcription input settings, and surface OpenAI realtime error/lifecycle events instead of leaving Talk stuck as live with no diagnostic. Fixes #73427.
 - Providers/OpenAI: resolve `keychain:<service>:<account>` `OPENAI_API_KEY` refs before creating OpenAI Realtime browser sessions or voice bridges, with a bounded cached Keychain lookup. Fixes #72120. Thanks @ctbritt.
 - Discord/gateway: reconnect when the gateway socket closes while waiting for the shared IDENTIFY concurrency window, instead of silently skipping IDENTIFY and leaving the bot online but unresponsive. Fixes #74617. Thanks @zeeskdr-ai.
 - Voice Call: add `sessionScope: "per-call"` for fresh per-call agent memory while preserving the default per-phone caller history. Fixes #45280. Thanks @pondcountry.
