Remote Control tells you when a credential expired instead of just dropping

You'll notice

Remote Control

An expired Remote Control credential now closes with a clear message telling you to run /login.

/login
What

Remote Control now separates auth failures from other disconnects. When the worker token expires or is rejected, the session closes with a dedicated code and the message points you at /login, instead of the previous generic re-authenticate wording.

Details
  • New close code 4094, "worker credential expired or rejected (code 4094)", used for token_expired and auth_exhausted.
  • epoch_conflict, epoch_stale and session_not_found keep close code 4090 and recover through the poll loop.
  • The cause-based mapping applies only when the transport is built with causeTypedCloseCodes; both v2 bridge call sites pass it as true, so it is live.
  • The 404-exhaustion path now names its cause explicitly as session_not_found.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
