Theorem 1 characterizes when an SCF is implementable, while Theorems 2 and 3 give necessary conditions; none states an algorithmic or complexity result. The proposed distribution over agent types would create a new mechanism-design question, rather than carry a computational question from this paper into a continuous society.
fails bit a — no named computational result to mirror
The proposed direction is not anchored in Theorem 1 or in the necessary-condition results of Theorems 2 and 3; the paper's results concern implementation and nearby type profiles, not a population distribution.
The best positive foothold is Theorem 1, proved in this paper: an SCF is continuously implementable up to level \(K\) exactly when it is continuous and satisfies SIRBIC. It gives a precise characterization of robust implementation under bounded reasoning, and could motivate a nearby population model for a large public program: agents share a finite set of complete preference-and-belief types, \(\mu_t\) is each type’s population share, and a designer chooses a report-contingent mechanism to implement a target allocation as \(\mu\) varies.
That would be a new continuum-agent mechanism-design problem, though, not a mirror of Theorem 1. The theorem’s continuity is about perturbations of type profiles and information, while the paper fixes a finite set of individuals; it says nothing about a population distribution. A nonatomic population could also change the incentive constraints that drive the theorem.
Under your anchor rule, this paper has no qualifying named computational result. Theorem 1 is an implementation characterization, and Theorems 2 and 3 give necessary conditions; none classifies an underlying problem as tractable or hard. So I can’t honestly supply a prover-ready continuous problem per anchor. The population model above is only an adjacent research direction, not a grounded continuous mirror of a computational result in this paper.
Theorem 1 is the proponent’s strongest anchor, and it does not meet the programme’s bar. It characterizes when an SCF is continuously implementable: precisely when it is continuous and satisfies SIRBIC. Theorems 2 and 3 likewise give conditions on implementation. None states the complexity of a computational problem or gives an algorithmic result. Here, “implementation” is an economic property of a mechanism, not a claim about computational complexity. So there is no named computational result in this paper to anchor a ChoCo mirror.
The proposed population model does not supply the missing anchor. In the paper, the finite set of individuals is fixed; continuity concerns perturbations of their types and belief hierarchies. Replacing those individuals with a distribution over preference-and-belief types would change the model’s central objects. Types encode beliefs about other, potentially identified players, while the SCF may respond to each player’s type. A population version would need new assumptions about symmetry, beliefs, aggregation, and how an individual’s report affects outcomes. Those are legitimate modeling choices, but they would define a new mechanism-design problem. To make it computational, one would also need to choose an input representation and a task—such as checking incentive constraints or finding a mechanism. The paper does not provide that task or a complexity result to transfer.
The mismatch is not that the paper already uses continuity: its continuous type spaces, lotteries, and robustness to nearby information are not continuous populations. Nor is the objection that a population model changes the answer. The gap is more basic: the paper offers no computational result whose question can be carried over to a continuous society. A computational study inspired by level-\(k\) mechanism design might be worthwhile, but its worth would have to be established on its own terms. The negative case is strongest for this paper under the stated anchor rule; it cannot prove that every related population model would be uninteresting.
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. These are the pipeline’s own outputs, generated by tools/triple_run.py — no human edited them. The paper’s own text is not reproduced here beyond the quoted statement above.
