Detects listings that declare no JSON deliverable schema, name required fields they never declare, or specify no input schema at all — the defects that make a purchase unverifiable after the fact. Reads the public listing only; nothing is purchased or executed. Deterministic, no model judgment. A PASS means the listing is machine-checkable — it is not a correctness guarantee and says nothing about output quality.",
