Runtime loading additionally checks artifact hashes, base64 canonical padding and pad bits, decoded-size correspondence, total byte bounds, registry digest and canonical registry sorting, the exact implementation binding set, matching implementation references, dependency and artifact references, and portable path collisions. Schema validity alone establishes none of those mechanisms, publisher identity, license authenticity, implementation correctness, dependency completeness, runtime availability, native-platform qualification, or authorization to execute. Loading and planning execute nothing.",
