 #### Deposits System (Simplified)
-- [x] `users.deposits_required` INT DEFAULT 3
-- [x] 48h notice required when `deposits_required > 0`
+- [x] `users.deposits_required` INT (0-3) tracks outstanding deposit obligations
+- [x] **24h late cancellation rule**: < 24h without forgiveness = `no_show` + 3 deposits (resets to 3, not +=), ≥ 24h = normal cancellation
+- [x] Optional `forgive_no_show` boolean at cancellation - admin can forgive penalty case-by-case, counts as `client_cancelled`
+- [x] Optional `enforce_deposits` boolean in admin booking creation - admin can bypass deposit checks when needed
 - [x] Reduces by 1 when booking completes with payment
-- [x] Increases by 3 on <12h cancellation (bad behavior)
-- [ ] Frontend display of deposits_required
+- [x] 2+ unforgiven no-shows in 6 months = 3 deposits (blocks new bookings)
+- [x] Deleted: `ForgiveNoShowsForUser()` function (now per-cancellation forgiveness)
+- [x] Implementation complete in `bookings.go` (24h threshold, forgiveness logic) and `manage.go` (admin deposit enforcement)
+- [ ] Frontend display of deposits_required status to users
 
 #### CalDAV Contact Sync
 - [x] Profile photos synced to CardDAV contacts (PHOTO field in vCard)
