The task's DurableTaskOptions.id (without the store namespace).
The slot this run covers (not the wall clock at which it started).
${taskId}@${scheduledAt.toISOString()}: stable per occurrence, so a run retried
after a crash or a lost lease reuses it. Use it as an idempotency key.
Fencing token of this claim: strictly increasing per task id (also across deletes). Pass it downstream to reject stale writes. The runs of one catch-up share their claim.
true when the run comes from the 'run-once'/'catch-up' missed-run policy.
Aborted when the scheduler stops or the lease on this occurrence is lost.
One occurrence of a durable task, passed to its handler.
