- ADR 0001: distinguish payment/OTP (sync by design) from notifications
(fire-and-forget); correct misleading claim that notification failures
surface to clients — they are silently absorbed as FAILED status
- risks.md: upgrade USERNAME_FIELD entry with concrete breakage (admin,
create_superuser, JWT lookup); add booking overlap race condition with
root cause and fix (select_for_update)
- architecture.md: document notification/OTP provider coupling as an MVP
shortcut and note the Phase 2 fix (dedicated NotificationProvider)
