# Third-Party Notices

Last updated: 2026-05-22

This public notice lists third-party software, model, runtime, font, and attribution subjects shipped by Boardoor. It reflects the operator's self-review for the beta release; a professional review remains an option before the official release and this is not final legal acceptance. Internal working notes, repository evidence paths, and release decision records are not included in this public artifact.

## Notes

- The CycloneDX SBOM at /licenses/sbom.cdx.json provides the machine-readable package inventory.
- The asset provenance summary at /licenses/asset-provenance-ledger.md lists public-safe asset and model provenance at a review-scope level.
- Font assets are shipped as glyph subsets limited to the characters each game renders, consistent with their in-game use license terms.
- This public artifact intentionally avoids internal file-system paths, CI workflow metadata, and private release work papers.
