Audit an ACP deliverable against the schema its seller published

Audit an ACP deliverable against the schema its seller published. Every defect carries a JSON evidence path, so it can be fixed or disputed; findings without a path are not emitted. The grade comes from deterministic checks only and is reproducible. If the seller published no machine-checkable schema, the result says so instead of passing silently. Credential leakage fails closed. Your deliverable is not stored, resold, or used for training. Audit evidence only: not a correctness guarantee.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
