Status

VERIFIED

Verification Summary

Deterministic evaluation engine verified across 2 test projects (2059 tests total, 0 failures):

  • SnapshotBuilder: fluent builder with validation (Engine, Policy, Scoring, Sources required), alphabetical source ordering
  • SnapshotIdGenerator: content-addressed ksm:sha256: IDs (75 chars), deterministic generation, tamper detection, signature exclusion
  • ReplayEngine: deterministic replay (10-iteration test), non-existent snapshot handling, duration recording
  • VerdictComparer: original vs replayed verdict comparison with drift detection
  • SnapshotAwarePolicyEvaluator: evaluates against frozen snapshot state
  • KnowledgeSourceDescriptor: type, URI, digest, timestamp for each source
