Tool changes

  • nenrin_ledger_entryadded

    Return ledger entry n as the ledger serves it: claim_sha256, the canonical record bytes, work description, OpenTimestamps status and Bitcoin block when anchored. Pair with jidec_how_to_verify to recompute it.

  • nenrin_ledger_headadded

    Return the current head of the JIDEC/NENRIN ledger: entry count n, the head hash, and the end marker bound into the chain (jidec-head-v1) with the recipe to recompute it. Compare it with a head you saw earlier to detect truncation or rewrite.

  • nenrin_witnessadded

    Return one NENRIN witness record by its record SHA-256: pending or anchored, and when anchored, the ledger entry and batch that carry it. Use it to check a walk someone says they submitted.

  • nenrin_trust_signaladded

    Return the compact NENRIN signal for an endpoint: counts of anchored measurements, witness diversity and freshness, in a shape a trust engine or orderer can read. No score, no allow or deny.

  • nenrin_resumeadded

    Return the NENRIN résumé of an agent or MCP endpoint: every recorded measurement that touches its origin (by the gate and by outside witnesses, signed or not), which are Bitcoin-anchored, discrepancies, rings, agreements, and the records not counted with the reason. Includes resume_sha256 and a recompute recipe. A history, not a score. Absent means no record, not a negative finding.

Tools (9)

jidec_citeread-onlyResolve and INDEPENDENTLY verify any JIDEC citation. Accepts 'jidec:path:<sha>', 'jidec:entry:<n>', a bare 64-hex id, or a ledger URL. Fetches the record's exact bytes, recomputes SHA-256 locally, and confirms it equals the cited id. Returns integrity, Bitcoin anchoring status, the parsed record (verification path, claim, or v0 spec entry), and an explicit statement of what the proof does and does not cover. No trust in HORIZON SHIELD is required to accept the result.
jidec_how_to_verifyread-onlyReturn the step-by-step recipe for verifying a JIDEC record WITHOUT trusting HORIZON SHIELD: which bytes to fetch, which hashes to recompute, which OpenTimestamps proof to check, which algorithm commit to check out, and what must match. Use this when you want to confirm the result yourself rather than repeat an assertion.
jidec_list_pathsread-onlyList the anchored JIDEC verification paths (most recent first), with purpose, verdict and Bitcoin anchoring status.
jidec_replayread-onlyRe-observe an anchored JIDEC verification path against the live system right now and report drift. Returns MATCH (the live system still matches what was anchored) or DRIFT (it changed), node by node. Nodes that cannot be re-observed server-side are reported as deferred, never counted as drift.
nenrin_ledger_entryread-onlyReturn ledger entry n as the ledger serves it: claim_sha256, the canonical record bytes, work description, OpenTimestamps status and Bitcoin block when anchored. Pair with jidec_how_to_verify to recompute it.
nenrin_ledger_headread-onlyReturn the current head of the JIDEC/NENRIN ledger: entry count n, the head hash, and the end marker bound into the chain (jidec-head-v1) with the recipe to recompute it. Compare it with a head you saw earlier to detect truncation or rewrite.
nenrin_resumeread-onlyReturn the NENRIN résumé of an agent or MCP endpoint: every recorded measurement that touches its origin (by the gate and by outside witnesses, signed or not), which are Bitcoin-anchored, discrepancies, rings, agreements, and the records not counted with the reason. Includes resume_sha256 and a recompute recipe. A history, not a score. Absent means no record, not a negative finding.
nenrin_trust_signalread-onlyReturn the compact NENRIN signal for an endpoint: counts of anchored measurements, witness diversity and freshness, in a shape a trust engine or orderer can read. No score, no allow or deny.
nenrin_witnessread-onlyReturn one NENRIN witness record by its record SHA-256: pending or anchored, and when anchored, the ledger entry and batch that carry it. Use it to check a walk someone says they submitted.
