Specification (Normative Core)

This page summarizes the normative guarantees and definitions of the DigiEmu Core public standard. It defines deterministic reconstruction of knowledge state and snapshot-verifiable verification.

Normative Guarantees

The following statements are intended as standard-level requirements. They define the audit surface.

Deterministic reconstruction

Given the same referenced inputs and the same replay procedure, the reconstructed knowledge state MUST be identical.

Canonical state encoding

The reconstructed knowledge state MUST be serialized in a canonical form so that hashing is stable across environments.

Snapshot hashing (SHA-256)

The snapshot hash MUST be computed over the canonical state encoding using SHA-256.

Independent verification

Any independent implementation MAY verify a snapshot by deterministic replay and hash comparison.

Evidence-based audit surface

Verification MUST produce a report that links the snapshot, referenced inputs, and the computed result (PASS/FAIL).

Invariant

Same inputs → same reconstructed state → same hash.

Definitions

Term

Unit

A versioned knowledge object. Units are the stable building blocks referenced by snapshots.

Term

Version

An immutable revision of a Unit. Versions are the only admissible replay inputs.

Term

Claim

An explicit assertion attached to Units/Versions. Claims are part of the auditable knowledge state.

Term

Uncertainty

A first-class element that represents incompleteness, ambiguity, or confidence bounds. Uncertainty is explicit, not implicit.

Term

Snapshot

A cryptographic identifier (SHA-256) of a canonically encoded reconstructed knowledge state, plus references to all admissible inputs required for deterministic replay.
