# Licensing and protocol provenance

> Locate Toolgrain licenses, upstream protocol terms, and integration notices.

Toolgrain-owned code is MIT licensed with copyright attribution to Keshav Katwe. The repository and package-local license files preserve the grant. Vendored upstream material retains its own unchanged terms.

## Protocol schemas

`@toolgrain/protocol` vendors the TypeScript and JSON schemas for both supported revisions from pinned upstream commit `271ecc9accafdd9b83a3c869fa67c22953b2af80`. Each revision has provenance, integrity checksums, and upstream license artifacts. The package's root LICENSE/NOTICE explain its mixed contents; its manifest uses `SEE LICENSE IN LICENSE`.

TypeScript schemas and provenance are distributed with compiled outputs. The JSON schemas are test-only conformance fixtures and are not copied to `dist`. Upstream updates require separate review and renewed interoperability verification. Do not modify or format vendored sources as part of an unrelated change.

## Integration notices

The Clerk package includes a NOTICE preserving Svix and Deno MIT attributions associated with `standardwebhooks@1.1.1`. Its npm archive omitted upstream parent-directory license/source attribution; Toolgrain preserves the exact release's notices and provenance. Keep the NOTICE in the Clerk archive and renew the review when updating that dependency.

## Documentation starter

The documentation setup includes material from Mintlify's starter. Its MIT
license, copyright 2026 Mintlify, is preserved unchanged in the
[starter notice](https://github.com/keshavkatwe/toolgrain/blob/main/docs/notices/mintlify-starter.txt).
Toolgrain-owned code and documentation use the repository's root MIT license.

## Brand and fonts

The approved Toolgrain mark, outlined wordmarks, lockups, shared tokens, and usage
guide live in [brand/](https://github.com/keshavkatwe/toolgrain/tree/main/brand).
The bundled Manrope source retains its SIL Open Font License and FONTLOG there.
This documentation site uses Mint's default typography and outlined logo exports;
it does not bundle the brand font. Outlined exports do not require a font installation.

Consult the actual [root license](https://github.com/keshavkatwe/toolgrain/blob/main/LICENSE), package license/notice files, and dependency terms when redistributing artifacts.
