## 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
