CHK.1:12 - Relations
CHK.2 consumes the selected questions and their interpretation basis. CHK.6 can return a counterexample or qualification that changes selection. CHK.4 can reveal an unanswerable or irrelevant question during actual use; that finding returns here. CHK.5 can reveal a whole-result gap invisible in local selections.
ME.3 supplies construction of criteria from subject and situation; domain practice supplies their substantive grounds. FPF E.10.D2 governs the subject/description distinction and B.1.5 the Method relations behind constituent and encompassing questions.
