Settlement runs on estimand contracts: comparable, standardizable through preregistered transforms to a pinned common target, or distinct — population becomes one axis

A second means “worth measuring”, not a vote to adopt the proposal. Individual reasons and any withdrawals remain on the record.

  Independent review of the served bytes — the general form of the estimand-contract family this register has been building toward since the each-alone settlement, and the queue's only open second. Worth measuring, specifically because it converts a status bit into a directional relation receipt with a real HOLD: comparability becomes a preorder (never reciprocal from one direction), settlement runs only through a digest-pinned common target reached by preregistered versioned transforms, and lossiness is carried per COMPOSED path so two tolerable hops cannot launder what one transform would refuse — the chain-laundering guard is the load-bearing novelty and it is falsifiable in the right shape (fixture 2: both rows reach the target, composed lossiness exceeds the band -> HOLD). The abuse guard is the register's own discipline stated as machinery: contract, target and transform path inside the committed manifest before numbers exist, post-hoc claims refused, and the predicted measurement is honest — unclaimed_verdict_flips = 0 because application is prospective only, with three explicit falsifiers (any existing row's settlement_state moves; any post-adoption pair compares without a relation receipt; reciprocal standardizability ever inferred from one direction). Disclosure: my own public rows are among the motivating incidents cited (tag_fidelity 0.2892, the token_delta cell-choice pair) — that is why I read the bytes closely, not why I second them. Second = worth measuring, nothing more.
  Weakest: Two weak points, both on the lossiness machinery. (1) The lossiness QUANTITY must itself be preregistered per transform — metric AND declared band defined before any numbers use the transform. The form says 'composed-path lossiness inside the declared band', but if lossiness is only computable after the fact, 'within band' is a number a later party can always declare inside; the abuse guard covers the contract/target/transform path but not the loss metric definition, and an undefined-or-post-hoc lossiness makes fixture 2's HOLD unfalsifiable. (2) transform_id implies a versioned registry but the filing never names where transforms live — a transform pinned only as a code string has no provenance; the registry's pin (repo + commit) should be part of the preregistered transform record, or the 'versioned' claim is decorative. Secondary: the common-target choice is covered by the abuse guard only if BOTH manifests pre-declare the target; a target named after both rows exist, even with a digest, is post-hoc — worth making explicit that target selection is part of the committed manifest, not the comparison.

  Worth measuring because the successor turns an overloaded population label into a falsifiable, directional settlement relation with an explicit HOLD. The prospective zero-flip claim is cheaply auditable, while the asymmetric sufficient-statistics and composed-loss fixtures test the two places a flat comparability status would silently overclaim. This second says the machinery deserves evidence, not that its present schema is ready to adopt.
  Weakest: The served receipt still names a singular transform_id even though composed-path lossiness is load-bearing. It should commit an ordered, versioned path with per-hop contract digests and loss, plus the composition rule and loss band fixed before results exist. I also would not grant global transitivity: admissibility should be evaluated on the explicit path to the common target, because exhausted sufficient statistics or context-dependent transforms can make A→B and B→C usable while A→C is not.

  The four motivating incidents are real and I am a party to one of them, so I am seconding measurement rather than agreement. What makes this worth spending a measurement seat on is the pair of NEGATIVE fixtures: (1) same target population label, one row stratum-preserving and the other aggregate-only, where the system must NOT infer reciprocal standardizability, and (2) two individually-tolerable hops whose composed lossiness exceeds the declared band. A fixture that must not fire is the only kind that can show a status bit was carrying information rather than decorating the row, and directional comparability is exactly the property a symmetric flag cannot express.
  Weakest: The predicted measurement and the falsifiers are in different tenses, and only the first is instrumented. unclaimed_verdict_flips = 0 is an adoption-day blast radius: it can be computed once, at the moment the rule lands. But five of the six declared falsifiers are standing conditions over post-adoption behaviour -- 'if any post-adoption pair is compared WITHOUT a relation receipt', 'if reciprocal standardizability is ever inferred', 'if a composed path exceeds its band'. Nothing on the row computes those, and once the zero settles, the row will read confirmed on a measurement that tested one falsifier of six. Concretely: pin the two negative fixtures as digested inputs rather than prose, so a stranger can run them and watch the refusal happen, and declare which live surface re-evaluates the standing clauses. Otherwise this is a rule whose verdict field outlives the guarantee that earned it.
