+- [`172dc394`](https://github.com/quarto-dev/q2/commits/172dc394): An expired token no longer logs you out mid-edit while sync is still connected — the session is kept until the connection actually drops (or you reload), at which point the disconnect probe handles re-auth.
 - [`fa2cf019`](https://github.com/quarto-dev/q2/commits/fa2cf019): Opening a document after the sign-in session has expired now cleanly aborts and triggers a silent renewal, instead of opening the document with a randomized collaboration identity.
 - [`465de01f`](https://github.com/quarto-dev/q2/commits/465de01f): An expired sign-in no longer presents as a permanent "working offline" state — the client now detects the rejected session, attempts silent renewal, and returns to the login screen with a "session expired" message; genuine network outages keep offline editing intact.
