+# Decision: Signing in asks before clearing this shift's signed-out work, and closing the question keeps it
+
+- **Status:** decided 2026-10-26
+- **Source:** `src/components/front-door/signed-out-work-prompt.tsx`, find "Closing the sheet keeps it, because clearing cannot be undone"
+
+On 26 Oct 2026 the owner approved the design wording in pull request 3836 and chose, by decision card,
+that closing the sign-in question keeps the work ("Approve, closing keeps"). When someone signs in on a
+phone holding this shift's call notes, handover drafts or timers made while signed out, the app asks
+whether to keep them with the account or clear them. Closing without choosing keeps them. Kept labels
+still clear at the end of the shift, at sign-out, at expiry and when a different account signs in.
+Before this they were cleared at sign-in without a word.
+
+If this summary and the source ever differ, the source wins.
