evidence-log

Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• get_evidence_head

  The current signed head of the evidence log: tree size, Merkle root and signature. Save it: any later head must be consistent with it.

• get_inclusion_proof

  Proof that the entry at leaf_index is in the tree, optionally at a given tree_size. Checkable offline with the public verifier.

• get_consistency_proof

  Proof that the tree at size first is a prefix of the tree at size second (or now): the log never rewrote history.

• get_checkpoint

  The log's signed checkpoint in the C2SP format witnesses cosign (origin, size, root).

• get_ledger_attestation

  The signed head hash of the hash-chained audit ledger of recorded quotes.

• get_usage

  How much is recorded, and by how many keys that are not ours. Counts only, nothing about anyone.

• record_evidence

  Record the SHA-256 of a decision record you keep yourself, so it can later be shown to be unchanged. Send the digest and a short kind, never the record. Needs your RiskRouter key in the Authorization

• get_chain

  The log's signed statement of one completeness chain as of the current head: its length and, for each position, the leaf, the time and the digest. A position nobody showed you is a record left out.
