Treating every failed swarm-task inspect as skippable opened a false-green window: a transient inspect failure on a still-running, non-whitelisted container skipped the stop and backed the volume up hot while the run reported success. Re-check whether the container is still listed; only a genuinely vanished container skips, an existing one re-raises so a broken daemon keeps failing the run loudly. Covered by unit tests for both paths. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
