JIDEC: Bitcoin-anchored public verification ledger (NENRIN)

Resolve 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.

Return 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.

List the anchored JIDEC verification paths (most recent first), with purpose, verdict and Bitcoin anchoring status.

Re-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.

Return one admission record (a2a-admission-v0) as the ledger stores it, by its canonical SHA-256: the exact record bytes, pending or anchored, and the ledger entry once anchored. A door writes one before it lets an agent's action run; version 0.4 carries the content check as fields only (a salted commitment to the content, the digest of the check, the rule set, decision, marks), no text. The anchored admissions of a relying party are also listed in admissions[] of its Résumé (nenrin_resume).

Return one agreement record as the ledger stores it, by its canonical SHA-256: the exact record bytes, pending or anchored, and the ledger entry once anchored. The anchored agreements of an endpoint are listed in agreements[] of its Résumé (nenrin_resume).

Return the day record (furui-check-day-v0) of the content check runner: the signed RFC 6962 root of one UTC day's check envelopes and their count. Give its SHA-256, or a day (YYYY-MM-DD) to find it through the runner's day status. This server reads the record from the ledger and the key from the ledger's /.well-known/furui-check-keys.json, and recomputes: the bytes hash to the SHA-256, the shape is closed, the key is listed for the record's heights, the Ed25519 signature verifies, and whether the record is anchored. No content, scope or answer text is in it.

Return envelope i of a closed UTC day as the content check runner serves it (kept 7 days after the day), with its RFC 6962 audit path. This server recomputes: the envelope has the closed shape (digests, numbers, booleans, fixed words; no text), the leaf hash is sha256(0x00 || canonical envelope), the audit path rebuilds the root of the day record the ledger stores, and the runner's Ed25519 signature verifies under the key the ledger lists. An admission of version 0.4 names the check of such an envelope by its digest.

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.

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.

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[] (anchored agreements), admissions[] (the anchored admissions whose relying party is on the endpoint's host: record_sha256, ledger entry, decision, the closed part of a 0.4 content block, revoked; no text), 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.

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.

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.
