- Added local TypeScript and Python SDK previews with shared Kujo digest and receipt conformance fixtures.
- Added signing-ready Ability Pack entry and trust-policy schemas plus an offline Ed25519, checksum, revocation, compatibility, and tenant-boundary verifier.
- Add an explicit cross-language v2 digest while preserving the existing runtime and receipt digest. The preview rejects decimals and integers outside JavaScript’s safe range.
- Add a fixture-only development kit for validation, reference docs, approval simulation, keyed replay, and receipt inspection.
- Include the development kit in the Kennel package.
- Rewrite the README with ecosystem badges, installation and quick-start
guidance, included contract surfaces, the current CMS Ability catalog, and
clear Agents SDK, MCP, Codex, and Cursor integration boundaries.
The Kujo runtime and existing receipt digests remain compatible. TypeScript and Python helpers are local previews, and the fixture server is not a production gateway.
Release verification passed locally and in GitHub Actions. Assets include the source archive, SPDX SBOM, checksums, and keyless provenance attestations.
