A grant refused while no calendar was chosen (for example during calendar listing) made a later push return no_calendar instead of google_reconnect_required, sending the household to choose a calendar when only connecting again helps. grantedConnection now decides the precedence for every Calendar call that uses the grant (listing, choosing, pushing): not connected, then a refused grant, then anything else such as no calendar chosen. It holds the existing cleared-token check, moved out of accessToken. Fixes F16-T4-01 for Maestro task b8d8da5a-0450-4571-963e-b3dfead24283. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
