zk-query-proofs skillA

zk-query-proofs is agent-read markdown (skill) from sparq-org/sparq: Prove and verify a SPARQL query result over committed RDF Verifiable Credentials in zero knowledge with sparq-zk + sparq-zk-compose — per-graph Poseidon2 commitments, BGP scan + integer FILTER Noir proofs, issuer Schnorr attestation (incl. hidden-key set membership), status-list revocation (clear- or hidden-index), verifier nonces / single-use replay defence, and the ProofManifest/circuit family. Use when building or driving the zk-query-proofs surface (proving a query answer, verifying a manife.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/zk-query-proofs@git:20260903.1a63aa7
Exact content
mdr add sparq-org/sparq/zk-query-proofs@sha256:b01fec7622d10238

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
