Don't treat "gone from the list" as a state transition

Symptom

An item vanished from the active list, so a cancellation notice went out. It was still there, the cancel count was 0, and it had already been fulfilled. Cause: missed at query time, or pagination incomplete.

Fix

• Judge a state only when a direct query for that state actually finds the item
• If not found, hold. Absence is not evidence.
• Expand the verification query to all states

★ The cost of a false positive is high. This verdict triggers a cancellation request to an external party.
