Synthetic media without provenance is a liability a brand cannot audit. Under the Shinjitsu Standard, every asset MIRAI Labo delivers carries C2PA metadata embedded at origin — creator, brand owner, creation method, timestamp — plus a certificate entry in the studio's public registry. Provenance does not indemnify a brand; it makes authorship provable, which is the foundation regulators and platforms are converging on. With EU AI Act Article 50 transparency obligations entering enforcement in August 2026, verified-at-origin production is moving from differentiator to requirement. MIRAI Labo has operated this way since founding.
