Schemas

Minimal JSON Schemas provide advisory shapes for common artifact table row kinds (e.g., api, a11y, e2e, contracts). They live under .specs/schemas/ and are validated during CI with a local, deterministic checker.

• Use proofdown_validate::schema_hint_for_kind(kind) to suggest a schema filename.
• Schemas are informative guidance for authors and validators; rendering layers remain strict about unknown or unsafe content.
