Normative technical documents for the H33 attestation infrastructure. These specifications use RFC 2119 conformance language and are intended for implementers, auditors, independent verifiers, and regulators. They are not marketing materials.
Defines the 74-byte fixed-width post-quantum attestation primitive. Covers the byte layout (32 bytes on-chain commitment + 42 bytes cached receipt), computation type enumeration, three-family PQ signature binding, chain anchoring procedures for Bitcoin (Taproot), Solana (memo), and Ethereum (calldata), and independent verification steps.
Defines the full attestation receipt JSON structure including receipt identity, input/output commitments, policy and authority hashes, chain linking via predecessor hashes, three-family PQ signature bundles, and the canonical hash computation rules (NFC normalization, little-endian encoding, length-prefixed fields, domain separators). Includes formal JSON Schema and worked examples.
Defines the directed acyclic graph (DAG) structure for attested governance decisions. Covers 8 node types (Route, Policy, Event, Result, StateTransition, Checkpoint, Federation, Anchor), edge semantics, Merkle root computation over BTreeMap-ordered nodes, deterministic replay semantics, canonical replay frames, integrity classification levels (INTACT, PARTIAL, DIVERGENT, BROKEN), and the relationship to HATS Section 4.
