What

Interrupting a session with queued commands emitted a second "cancelled" lifecycle callback for commands whose cancel had already been acknowledged, and listed them again as still queued.

Details
  • The command queue gains consumeCancelPendingAcked / hasCancelPendingAcked on top of the existing cancel-pending set
  • Drain suppresses a second "cancelled" lifecycle callback for a uuid whose cancel was already acknowledged
  • The interrupt control_response filters those uuids out of still_queued
  • Affects SDK clients watching command lifecycle around cancel_queued
Evidence

consumeCancelPendingAcked

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
