# Asset Provenance Ledger

Last updated: 2026-05-22

This public ledger summarizes asset, model, font, and converted runtime provenance 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. It intentionally omits internal evidence paths, local file-system paths, and release workflow notes.
