 - iOS/Android Talk Mode: explicitly `chat.subscribe` when Talk Mode is active, so completion events arrive even if the Chat UI isn’t open.
 - Chat UI: refresh history when another client finishes a run in the same session, so Talk Mode + Voice Wake transcripts appear consistently.
 - Gateway: `voice.transcript` now also maps agent bus output to `chat` events, ensuring chat UIs refresh for voice-triggered runs.
+- Gateway: auto-migrate legacy config on startup (non-Nix); Nix mode hard-fails with a clear error when legacy keys are present.
 - iOS/Android: show a centered Talk Mode orb overlay while Talk Mode is enabled.
 - Gateway config: inject `talk.apiKey` from `ELEVENLABS_API_KEY`/shell profile so nodes can fetch it on demand.
 - Canvas A2UI: tag requests with `platform=android|ios|macos` and boost Android canvas background contrast.
