v1.4.0 seals replay and audit hardening.
Highlights:
- EvaluationEvent and ReplayBundle
- ReplayEngine
- append-only EventStore and hash chain
- audit export, integrity verification and tamper detection
Verification: 246 passed + 3 subtests; v1.2/v1.3/v1.4 black boxes 9/9 each; compileall passed; protected-core diff remained empty. Payload, replay_ref and recorded_at tampering were detected.
Boundary: Exact Replay is the explicitly verified focus; full Semantic/Explanatory degradation remains future work.
