Read-only mode
Read-only mode is the state a syndicate enters when its 14-day grace period expires without the failed payment being resolved. From day 15 onwards, no new writes go through: no bookings, no usage logs, no expenses, no finalisation, no member or asset changes. Reading every screen still works.
A clear banner tells members the syndicate is read-only. The owner resolves the failure from the web version’s subscription settings; a successful retry restores full read-write immediately. The grace period is forgiven on success — the clock does not carry over to the next failure.
Lapsed subscriptions drop back to the free tier if the syndicate fits within the free-tier limits; otherwise read-only applies until either the subscription is restarted or the syndicate is brought within the free-tier limits.
