/**
 * Atomically freezes a validated draft and accepts at most one execution. Same keyed request returns the original acceptance before checking stale If-Match. A different key cannot queue a second execution. Invalid validation returns 422 VALIDATION_INVALID; stale validation/config returns 409 VALIDATION_STALE; a different key after acceptance returns 409 ALREADY_COMMITTED. After admission shutdown recover via GET status/results; mutation retries may return 503 instead of replaying 202.
