Measured tools (8)

• commit

  Commit to a deliverable BEFORE handover. commit_hash = sha256(salt || sha256(content)) as 64 hex chars; deadline is ISO-8601; context links the escrow/job. Idempotent per (committer, nonce).

  Parameters:

  • committer (required) — string
  • nonce (required) — string
  • commit_hash (required) — string
  • deadline (required) — string
  • context — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• reveal

  Reveal the committed content's digest + salt after handover. Verifies against the commitment (one bit of drift fails); returns a delivery_proof string for escrow release. Late reveals expire the commitment.

  Parameters:

  • commitment_id (required) — string
  • salt (required) — string
  • content_digest (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• verify

  Independently verify a revealed commitment; optionally check it against the digest of content you received.

  Parameters:

  • commitment_id (required) — string
  • content_digest

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• commitment_status

  Current record for a commitment (pre-reveal, salt/digest stay hidden).

  Parameters:

  • commitment_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_commitments

  List commitments, optionally filtered by state (PENDING|REVEALED|EXPIRED).

  Parameters:

  • state

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• seal_outcome_receipt

  Seal an agent output as an Outcome Receipt (ORC v0.1) and register its commitment. Returns a portable receipt anyone can verify offline (L1) and against this notary's registry (L2). The notary attests integrity and time ("notarized"), not correctness. No floats in output; stores only digests. Spec: docs/standards/OUTCOME_RECEIPT_v0.1.md

  Parameters:

  • output (required) — object
  • profile — string
  • subject
  • bindings
  • excludes

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_orc_commitment

  Registry lookup: is this ORC commitment sealed by this notary? Returns digest, issuer, profile, attestation and registered_at, or NotFound.

  Parameters:

  • commitment (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• describe_agent

  Return capabilities and input contract.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
