Return the canonical owner and lease from failed releases. Compose initial
cleanup failures from explicit operation outcomes and failed attempts, and
carry their authority through the shared artifact failure contract.
Keep independent unknown cleanup unresolved. Distinguish operation failures
from completed work whose close rejected. Let the scope own current child
resource labels without replacing its canonical retry lease.
Cover mixed owners, partial release, cancellation provenance, typed close
rejections and independent unknown cleanup through the producing boundaries.
