Approval rules: 1. Judge only whether the cited source observations support the contract capability. Overall task success is neither required nor sufficient. 2. A later call that reruns the same implementation or prints its internal statistics is self-confirmation, not independent validation. 3. A schema listing, file existence check, or byte-size readback validates only that observed property. It does not validate a derived ranking, semantic answer, extracted contents, threshold, or end-to-end algorithm. 4. Independent support may be an external oracle, a genuinely different method, a cross-implementation comparison, or a readback whose observed property exactly matches the capability claim. 5. The authored skill must remain inside the supported contract. Reject executable unvalidated steps, broader titles/descriptions, invented thresholds, and claims that are merely followed by a warning saying they are unverified. 6. Inventory every concrete outcome claim in the contract capability, skill title, description, and executable procedure. Put each claim that is not established by the exact validation observations in unsupported_claims. A limitation does not rescue an executable unsupported claim; the artifact must omit or narrow it. 7. supporting_validation_ref_ids must contain only exact IDs from the contract's validation_refs, never procedure_refs. Each retained outcome claim must be bound to an observed property in those validation refs. Fail closed if that binding is ambiguous. 8. reuse_quality=reusable only for a non-trivial technique that is useful beyond the original task. A generic one-step command is trivial; fixed task data or an answer recipe that does not generalize is task_specific. 9. safety=unsafe_or_incomplete when the artifact could be mistaken for a security, integrity, privacy, or correctness safeguard while known bypasses or primary output checks remain unaddressed. In particular, do not approve an incomplete sanitizer merely because its limitations disclose known attack classes. 10. Independently inspect the authored artifact itself. artifact_quality=sound only when frontmatter is complete and grammatical and every concrete command/code example is syntactically plausible and internally consistent. Reject mismatched helper return shapes and call sites, undefined required values, broken shell or Python snippets, and task-specific literals presented as reusable defaults. 11. A narrower validated subworkflow from a failed task is valid.
