Measured tools (9)

• jidec_cite read-only

  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.

  Parameters:

  • citation (required) — string — jidec:path:<sha> | jidec:entry:<n> | 64-hex | ledger URL

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• jidec_replay read-only

  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.

  Parameters:

  • citation (required) — string — jidec:path:<sha> | jidec:entry:<n> | ledger URL

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• jidec_list_paths read-only

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

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• jidec_how_to_verify read-only

  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.

  Parameters:

  • citation (required) — string — jidec:path:<sha> | jidec:entry:<n> | 64-hex | ledger URL

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• nenrin_resume read-only

  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.

  Parameters:

  • endpoint (required) — string — https URL of the agent or MCP endpoint, e.g. https://mcp.horizonshield.dev/mcp

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• nenrin_trust_signal read-only

  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.

  Parameters:

  • endpoint (required) — string — https URL of the agent or MCP endpoint

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• nenrin_witness read-only

  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.

  Parameters:

  • sha256 (required) — string — 64-hex record SHA-256

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• nenrin_ledger_head read-only

  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.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• nenrin_ledger_entry read-only

  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.

  Parameters:

  • n (required) — integer — entry number

  Hints: read-only yes · destructive no · idempotent yes · open-world yes
