jidec_cite
Cite and independently verify a JIDEC record
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.

jidec_how_to_verify
Get the executable verification recipe
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.

jidec_replay
Re-observe an anchored path and report drift
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.

nenrin_ledger_entry
One ledger entry by number
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_head
Current ledger head and its bound end marker
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_resume
Recorded conduct history of an endpoint (NENRIN résumé)
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.

nenrin_trust_signal
Compact conduct signal of an endpoint
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_witness
One witness record by its SHA-256
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.
