Define the expected failure boundary
List which information and actions require a signed-in user. When access expires, private task data should not remain available merely because a screen was already open. At the same time, a harmless local draft may be worth preserving if the product’s privacy design permits it. Decide that behavior deliberately instead of letting a generic error handler either erase everything or leave an unsafe stale view.
Diagnose authentication and operation status separately
Signing out does not necessarily cancel a server operation already accepted. Keep the original request identity in the appropriate protected store and reconcile its outcome after access is restored. Do not create a new build, message or record simply because the browser lost its session. A successful sign-in proves access was restored; it does not by itself establish whether the earlier operation completed or failed.
Test the transition with fixed responses
Use an isolated responder to simulate an expired session while a task is pending. Check private-data cleanup, disabled actions, focus and the recovery explanation. Then restore the permitted test state and inspect the original operation. Do not expire real customer sessions or alter live credentials just to exercise the interface. This is an original acceptance scenario, not a finding about a tested Overskill implementation.
Make the recovery message precise
Tell the user whether signing in is necessary and whether their original task is still being checked. Avoid saying that all work was lost unless that is established. Keep a supported path back to the original brief or result, and do not expose information from a previously selected account. Session recovery is successful when authorization, identity and understandable status align, not simply when a login page disappears.
