## Evidence checks

- [ ] Behavioral contract predates or is independent from implementation work.
- [ ] Normative and public sources are listed with revisions and evidence paths.
- [ ] Contributor source-exposure disclosures are complete.
- [ ] Required separation/counsel decisions are attached.
- [ ] No copied source, comments, tests, identifiers, non-normative constants, or distinctive internal structure were found.
- [ ] AI inputs and human review satisfy the contributor guide.
- [ ] Intentional incompatibilities are approved and versioned.
- [ ] Conformance, malformed-input, security, resource-limit, and fuzz evidence meets the component gate.
- [ ] Bundle graph, native hashes, SBOM, ownership inventory, and clean-install graph agree.
- [ ] Licenses, patents, trademarks, and specification terms have an explicit disposition.

| Fuzz/conformance | deterministic 20,000-case corpus | engineering pass | Independent rerun pending |
| Cross-platform | Windows local | partial | Linux and macOS CI pending |
| Artifact ownership | ownership audit and package verifier | pending | Attach candidate reports |

## Decision
