A system and method for managing a persistent digital avatar and its associated assets across multiple 3D rendering platforms is disclosed. In a further aspect, a governance framework maintains identity persistence and policy inheritance for such assets, particularly when they are recreated from indirect evidence. The framework uses a verifiable Derived-Asset Receipt to cryptographically bind an output asset to its evidence, reconstruction pipeline, and a governing policy anchor. Enforcement points within a destination pipeline, such as a game engine or marketplace, gate acceptance of the asset based on verification of the receipt, thereby preventing the use of non-compliant or unauthorized assets.
