WalkthroughThe logout flow now deletes the first device returned by ChangesLogout device cleanup
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Logout now removes the cached notification device instead of fetching a token, but teardown ordering may leave an authenticated connection active after logout and a failed remote device deletion may leave notifications registered. The change is mergeable with explicit owner awareness and follow-up testing for complete logout cleanup. Suggested reviewers: Poem

- Line 145: Update the logout/cleanup flow around CallJoinViewModel and
streamVideo.deleteDevice so the video client disconnects before its coroutine
scope is cancelled, allowing activeCall.leave() cleanup and socket closure to
complete. Add a regression test covering logout with an active authenticated
client and verify the WebSocket is disconnected.

Broken Authentication (CWE-613): Insufficient Session Expiration
Reachability: External
Disconnect the video client before cancelling its scope. StreamVideo.removeClient() cancels the client scope before activeCall.leave() can run its cleanup, and no socket disconnect occurs. An active authenticated WebSocket can therefore remain open after logout. Add an active-client logout regression test.

getDevice() is DataStore-backed, so .first() can throw IOException and nothing here catches it — if it does, removeClient() and isLoggedOut = true never run. Worth runCatching { ... firstOrNull() }? The deleted fcmToken had a try/catch for the same reason.
