Statement
The claim asserts that the earlier split bill for Robust Openness, a silent prefix clause, route persistence allowing a named replacement, and standing, is, given actual coverage, Robust Openness itself factored by a case split on whether the concern is live at the actual prefix, and not an independent sufficient condition. The declaration certifies exactly that equivalence over an abstract finite scenario: with actual coverage inside the protected routes, the conjunction of the three clauses is logically equivalent to coverage and standing in every declared counterfactual. The gaps: the declaration's RobustOpen quantifies over the declared counterfactuals only, while the wiki's Robust Openness at a state conjoins the actual branch (the file's RobustOpenActual adds it, and its counterfactual_open_not_actual shows the two differ), so the equivalence is with the counterfactual half; the scenario abstracts coverage to booleans and does not model how a counterfactual state is produced, so nothing here is a causal non-capture theorem, as the file says of itself; and the claim's force as a correction (the bill is no certificate) rests on the companion results that the componentwise persistence bill is strictly stronger, which this record does not certify.
