Theorems 1–3 establish equivalences among stability concepts and coalition-proof outcomes, but none claims an algorithm, complexity bound, hardness result, or computation using the strategic form. The proposed type mass matching market is a plausible follow-on, but defining blocking and executable deviations for it would create a new model rather than mirror a computational result in this paper.
fails bit a — no named computational result to mirror
The suggested follow-on concerns matching among repeated preference and quota types, but it covers none of the paper’s named results as a computational result.
The paper has no named computational result that qualifies as an anchor. Theorem 1, proved here, says that pairwise-stable matchings and credibly group-stable matchings coincide when firms have responsive preferences and workers have categorywise-responsive preferences. Theorem 2 adds that, on the same domain, those matchings are exactly the outcomes generated by coalition-proof Nash equilibria. Theorem 3 extends the equivalence to general non-bipartite matching problems when all agents have responsive preferences. These are structural results about solution concepts; the paper does not establish a complexity classification or compute with a formulation. So there is no eligible anchor, and I can’t honestly supply the requested anchored continuous problem.
There is a plausible setting for a *follow-on* mirror: a large regional medical-intern market with many interns and consultants but a smaller set of repeated preference-and-quota types. A type would specify an agent’s side, full preferences over partner sets, categories, and quotas; mass would be the fraction of that side with the type; and a matching would be a flow of mass between types, constrained by capacities and category quotas. One could ask whether such a market has a feasible flow immune to pairwise blocking and to executable group deviations. That is a reasonable direction suggested by the paper, but defining executable deviations for a continuous population would require additional modeling, and the question would not mirror a named computational result in this paper.
The strongest case against a mirror is that this paper supplies no computational result to mirror. Theorems 1–3 identify when pairwise stability, credible group stability, and coalition-proof outcomes coincide. They give no complexity classification, algorithm, or optimization problem. Theorem 2 adds a game-theoretic representation; it does not turn the equivalence into a computational task.
The best version of the proposed follow-on is a large matching market with repeated intern and consultant types, where a type records preferences, categories, and quotas. One could seek a mass allocation with no pairwise blocks or executable group deviations. That is a plausible high-multiplicity setting, so I would not reject it on the ground that matching agents cannot repeat.
The problem is that a type-to-type flow does not directly carry the paper’s central concepts. Its pairwise blocks are named bilateral links; its executable deviations depend on which individual coalition members keep or drop which links; and its CPNE result recursively tests deviations in a game of individual strategies. In an atomless population, an individual link has zero mass. Requiring positive-mass blocks or coalitions can restore a nontrivial question, but it requires specifying how agents receive integral partner sets, how mass splits across those sets, and what counts as a credible deviation. That would be a new continuum matching model, not a computational mirror of a result in this paper.
So the negative case is strong against treating this paper as an anchored ChoCo example: it has no computational anchor, and the natural follow-on changes the object being studied. It is weaker against the universal claim that no worthwhile continuous question exists. A carefully defined continuum matching problem could be worth studying; the paper itself does not establish that it would be.
The adversarial triple: the proponent anchors on up to three named results; the opponent sees that case and must defeat every anchor; the judge decides which case convinced it.
