TEST-057

Stimulus

livesnapshotting, onlinesnapshotting, paused, saved, aborted, unavailable state, and UUID mismatch; competing shared or same-identity sessions, alternate control routes and unproven OS permissions; a timed-out, non-cancelable, failed, or lost progress operation; reserved snapshot entries and distinct snapshot/progress identifiers; crash or rollback before progress-ID recovery

Required observation

No unsafe VM-control or storage mutation occurs, even with hard-poweroff opt-in. Do not interchange task IDs and snapshot UUIDs; unproven outcome or quiescence, current state, or a third-party interlock blocks mutation. Successful completion and matching current snapshot name and UUID do not exclude later competing operations.
