Protocol

Local verification before public claims.

The CLE Protocol connects canonical data, record hashes, archived snapshots, typed ProofGraphs, browser verification, and an optional challenge-capable contract. It makes integrity and claim boundaries inspectable without turning a hash into a truth claim.

Protocol Components

  • Canonical JSON and CSV artifacts in data/.
  • Record hashes and dataset hashes regenerated from the current source files.
  • Snapshot manifests archived in data/snapshots/.
  • Release verification artifacts that record the commands and limits for each public package.
  • ProofGraph compiles every record into typed source, claim, response, limitation, and certification nodes.
  • A snapshot-wide Merkle registry proves that each record graph belongs to the published registry root.
  • The optional smart contract records commitments, registered attestations, permissionless challenges, responses, and supersession lineage.

Verification Commands

  • npm run hash:data regenerates record and snapshot hashes.
  • node scripts/hash-dataset.mjs --check checks committed hashes against current data.
  • npm run validate:data validates canonical data and schema consistency.
  • npm run check runs the broader local release gate.
  • npm run proofgraph:verify -- --all recomputes every graph and registry inclusion proof.
