Reinstate a cancelled session

POST
/events/{eventId}/sessions/{submissionId}/reinstate

Clears the cancellation and reopens tasks that were waived by it. With notifySpeakers on, speakers get a reinstatement email — carrying a fresh calendar invite when the session is scheduled and invites had gone out; otherwise the schedule is flagged so a fresh invite can be sent later.

Cancel a session POST

Cancels the session with a recorded cause (organizer or speaker). The acceptance stays on record and the schedule is kept as history; the session leaves the agenda and public pages, its open tasks are waived, and — when notifySpeakers is on — speakers get a cancellation email carrying a calendar cancellation if invites went out.

Delete a manually added session DELETE

Mistake cleanup for manual sessions only — CFP-origin sessions keep their submission history and must be cancelled instead.
