turn/unqueue

Reclaims a queued submit before it launches; never upgrades into a cancel once the target is running.

Parameters

Type: TurnUnqueueParams

turn/unqueue params: reclaim a queued submit before it launches. It is not a stop — a reclaim that arrives after its target launched is durably rejected, never silently upgraded into a cancel.

Field	Type	Stability	Presence	Description
commandId	string		required	The idempotency handle (UUIDv7).
sessionId	string		required	The target session.
turnId	string		required	The queued turn to reclaim, exactly as the queueing turn/start’s ack minted it and as snapshot queuedTurns lists it. Required, and never “whichever is newest”.
