Disconnect deleted the connection but left every pushed plan synced with its stored event ids, though no calendar was chosen any more. It now deletes the connection and runs the same invalidation as choosing another calendar (forgetEvents: MarkCalendarPlansEdited, ClearCalendarEvents) in one transaction, under the account lock. A refused revoke still changes nothing. Tests push three weeks, disconnect, and check each is changed with no event id; then connect again, choose a calendar and push the whole week to it. Also: a refused revoke keeps every week synced, and a disconnect during a push waits for its record and then forgets it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
