Crate dpp_vc 

dpp-vc — the trust layer: who may read a passport, and how that is proven.

W3C Verifiable Credentials, did:web documents, Bitstring Status List revocation, and the JSON-LD context those are expressed in.

Pure (no I/O, no network). Not a wasm32-unknown-unknown target: it depends on dpp_crypto, whose RNG requires a platform entropy source.

Trust, not primitives, and not policy

Three neighbouring concerns are deliberately not here:

• Cryptographic primitives — JWS, keys, the keystore — are dpp_crypto, which this crate depends on. Signing bytes is a different job from deciding whose signature means what.
• The disclosure contract — Audience, Disclosure, the per-field disclosure map and the filter that applies it — describes what a passport is, not who is asking. It currently lives in dpp-crypto::access; its settled home is dpp-domain.
• Projections — GS1, AAS — render a passport for an ecosystem. They say nothing about trust.

The seam this crate sits on: a credential establishes which Audience a caller holds; the disclosure policy maps that Audience to fields. Those are two questions and they are answered in two places.
