3. Definitions

3.1 Canonical Serialization

The deterministic transformation of structured data into a byte-identical UTF-8 encoded representation according to Annex A.

3.2 Canonical Evidence

Evaluation input data serialized in canonical form and used as the basis for hash derivation and replay validation.

3.3 Rule Identity

A cryptographic hash derived from the canonical serialized representation of a rule definition as defined in Annex B.

3.4 Deterministic Replay

Re-execution of evaluation logic under identical canonical evidence and rule identity conditions producing identical outcomes.

3.5 Replay Equivalence

A Boolean condition evaluating TRUE only if recomputed evidence hash, rule identity hash, decision, state, and artifact hash match original issuance values.

3.6 Conformity Artifact

A structured record containing evidence hash, rule hash, evaluation outcome, and artifact hash as defined in Annex E.

3.7 Conformance

Verified adherence to all mandatory sections and annexes of Trust-State Standard v1.0.

3.8 Certification

Formal recognition that an implementation satisfies all conformance requirements under Annex F.
