  "scope": "Common life-event clocks and retained-state kernels give exact equality of complete pruned history laws, including under shared retained-history policies. Equality of forty coupled numerical records is an illustration, not the proof. Hidden sister/family observations, survivor selection and molecular-conservation constraints are excluded."
