Bookings

Lifecycle

• pending — requires-confirmation event types start here
• confirmed — normal state
• rescheduled — the old booking after a reschedule (the new one is confirmed; from_reschedule links them)
• cancelled — either party cancelled
• rejected — pending was declined

Reschedule vs cancel+rebook

The reschedule-booking action creates a new booking with a link back to the old via fromReschedule. iCalUID is preserved across the reschedule chain (RFC 5545), and iCalSequence is bumped.
