Signals become
new questions.

Meta's Muse Code makes every model call, tool run, approval and edit part of an append-only event log for exact replay and crash-safe recovery. That establishes runtime reproducibility—not that the log is complete, authority remained valid or the claimed effect occurred in the world.

Formalize replay-to-world correspondence. Hold an event log constant while changing independent evidence, live authority or external state, then score replay fidelity, coverage and verified consequence separately.

When unverified framing disappears through summary, memory or handoff, risky approval can rise even though the underlying proposition is unchanged.

Bind verification state, evidence, verifier, method, timestamp, scope and authority directly to claims through every transformation.
