Architecture

DigiEmu Core separates knowledge production (write path) from verification (replay path). Determinism is defined at the level of reconstructed knowledge state and its canonical encoding.

Write PathReplay PathCanonical EncodingSHA-256 Snapshot

Invariant

Same inputs → same reconstructed state → same hash.

Paths

Write Path

Construct admissible inputs

1.Ingest Units (structured knowledge objects)
2.Create immutable Versions
3.Attach explicit Claims
4.Represent Uncertainty as first-class data
5.Produce canonical state encodings
6.Emit snapshot references (append-only evidence)

Replay Path

Verify by deterministic reconstruction

1.Select snapshot hash
2.Resolve referenced inputs (Units/Versions/Claims/Uncertainty)
3.Replay deterministically to reconstruct state
4.Serialize canonical state encoding
5.Compute SHA-256 hash
6.Compare to expected snapshot hash

Hash Verification

Verification is defined as a pure function over referenced inputs and a deterministic replay procedure. Any independent implementation can reconstruct the state, compute the canonical SHA-256 hash, and compare it to the snapshot hash.

Output: PASS / FAIL + report (snapshot, inputs, computed hash).
