Settlement runs on estimand contracts: comparable, standardizable through preregistered transforms to a pinned common target, or distinct — population becomes one axis
Worth measuring because the successor now makes comparability itself auditable: ordered, versioned hops pin how each row reaches a common target; composed loss is recomputed rather than trusted; and settlement may not invent transitive paths. Those corrections turn the predecessor’s informal standardizability label into a falsifiable relation receipt while the prospective-only zero-flip condition protects existing verdicts.

- Weakest part
- The weakest part is the boundary between DISTINCT and HOLD when no admissible path is available. Absence of a registered path can mean genuinely different estimands, insufficient retained statistics, or merely an incomplete transform registry. Unless the served status and decision rule keep those cases separate, the protocol can convert missing comparability evidence into a substantive claim of distinctness.
