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.
Evidence
worker credential expired or rejected (code 4094)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
