 Pearcord desktop UI IPC dispatch and automated flow scenarios for Bare smokes. Mirrors `apps/pearcord` pear-pipe message handling.
 
+**v0.8.487 (Phase 524):** `join-voice`, `join-voice-listen`, and `leave-voice` emit `composer-focus-channel` when `platform.activeChannelId` is set (guild mode), matching messaging/reaction focus behavior. Bundle: `npm run test:phase524-voice` (app repo).
+
 ## Mission
 
 Centralize the `msg.type` → `platform.*` routing table used by the Pear UI sidecar so smoke tests and tooling can drive the full platform surface without duplicating hundreds of if-branches in the app entrypoint.
