HiveAttest

Issue a Pre-Action Attestation Manifest (C15: hive-passport). Signs with Ed25519 over RFC 8785 JCS-canonical body. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Verify a Pre-Action Attestation Manifest (C15: hive-passport). Checks Ed25519 signature, temporal validity, and optionally observed inputs hash. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Append a node to a custody chain (C16: hive-custody). Taint propagates: once tainted, always tainted. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Verify a custody chain: hash linkage, Ed25519 signatures, and taint propagation (C16). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Retrieve a Merkle inclusion proof for a specific node in a custody chain (C16). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Register a versioned cargo type in the HiveAttest registry (C17: hive-cargo-taxonomy). Pins a definition hash for version-anchoring. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Validate a payload against a registered cargo type schema (C17). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Get a registry snapshot with Merkle root for version pinning (C17). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Issue an attestation warranty committing an agent to a claim (C18: hive-attestation-warranty). Signed with Ed25519. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Report a warranty breach. Marks the warranty as breached and returns a signed breach record (C18). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Retrieve a warranty by ID (C18). Reference-grade implementation. Wire format normative; production-grade is Layer B.

THE HEADLINE TOOL. Evaluate whether an agent may proceed through the HiveAttest gate (C19: hive-gate-enforcer). Verifies passport signature + expiry, cargo registry membership, and warranty status. Every response (allow OR deny) includes a signed C18-format receipt of the gate decision. Reference-gr

Probabilistic secondary inspection of a record batch (C20: hive-secondary-inspection). Returns a signed inspection record. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Verify a SMSH-Stamp v1 receipt (C8/C12: smsh-stamp-verifier). Validates schema, version, algorithm, timestamp, and Ed25519 signature. Reference-grade implementation. Wire format normative; production-grade is Layer B.

Build a sorted Merkle tree for an audit window (enables cryptographic non-membership proofs, C13: prov-absence). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Prove that a query event is NOT a member of a previously-built audit window (C13). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Verify a non-membership proof against an expected Merkle root (C13). Reference-grade implementation. Wire format normative; production-grade is Layer B.

Return HiveAttest layer/spec/patent metadata for all claims. Useful for agent introspection. Reference-grade implementation. Wire format normative; production-grade is Layer B.
