Module barrier 

Validate-before-render barrier needs full modalities::logic::geometry_asset_shacl (not modalities_lite / wasm-ontology-only). Validate-before-render barrier (P2)

A strict, fail-closed gate that must pass before geometry is accepted for rendering. Validates the relational SHACL rules of the manifest, checks the .10d whole-file CRC, decodes the provenance sidecar, asserts the immutable source_digest, ensures the presence of a licence (context not stripped), and optionally verifies any attached Verifiable Credentials against grounded issuers.
