Perform a post-result qualitative analysis without changing the official V3 decision. Trace each miss back to the proof structure that produced it rather than adding a checklist of fixture-specific mistakes. The configuration failures omit the semantics of combinators such as all and not, then assert closure of the resulting product or complement. The exact-domain failures compress an ordered, fallible build into an endpoint mapping and therefore cannot reconstruct which intermediate states are reachable. Several reports state that two sets are incomparable without giving both separating witnesses. One otherwise-correct report omits authority for the usize domain. Another seeks a maximal bad-input remainder even though one complete existential witness is sufficient for UNSOUND. These observations explain why Required/Covered and verdict certificates were necessary but not sufficient: the representation still allowed lossy summaries to masquerade as exact derivations. They motivate V4's explicit case domains and fibers, set-relation certificates, staged construction relations, reversible transformations, and demand-driven counterexample scope. Keep these as general proof obligations rather than embedding the evaluated fixtures in the runtime skill. gherrit-pr-id: Glzlcl663nbggljjqi64x7gs3yyw5b7ys
