* fix(codex): settle sandbox processes and readiness probes
* fix(codex): revoke sandbox termination signals at exit
* fix(codex): preserve sandbox command process identity
* fix(ci): recognize cancellation-aware sandbox upload checks
* fix(ci): register sandbox upload scanner fixtures
* fix(gateway): settle cancelled chat waiters
Publish cancellation completion from the common dispatch finalizer for both resolved and rejected runtimes. Preserve the abort marker captured before rejection cleanup, session binding, and completed-delivery barrier.
Release-note context: agent.wait already watching a chat.send now finishes after chat.abort, including CLI runtimes that resolve with partial output. The real Gateway regression fails on the original code and passes after this owner repair; 59 focused tests, selected changed checks, final targeted checks, and independent P2 review passed.
* test(pdf): cancel worker extraction deterministically
Abort synchronously after submitting the real extraction so a worker result cannot race the former zero-delay timer. Preserve exact cancellation reason, pre-aborted rejection, and successful subsequent extraction assertions.
