Theorems 1, 5, and 6 characterize truthful reporting and mechanism forms, but none states an algorithmic, complexity, hardness, or computational-formulation result. The opponent also explains why the natural nonatomic extension changes or trivializes the strategic incentives, though the failure of bit (a) is decisive.
fails bit a — no named computational result to mirror
The proposed footholds are Theorems 1, 5, and 6; none has a computational mirror, and the paper states no other named computational result to cover.
I can’t make an honest continuous-mirror case anchored in this paper’s results: it contains no named computational result of the kind your criteria require. Theorem 1 says every implementable outcome function can be implemented with direct, truthful messages. Theorem 5 says that, under evidentiary normality, any outcome function implementable by a dynamic mechanism is also implementable by a static one. Theorem 6 says any dynamic implementation can be replaced by a special three-stage mechanism with truthful reporting in equilibrium, with a simplification under complete information. These are structural implementation results, not claims about complexity or algorithms for encoded problem instances.
Theorem 5 is the strongest foothold for a broader research idea: ask whether static mechanisms suffice in a continuum-population model with normal hard evidence. But that would not be a mirror of a computational result in this paper, and the population model would need new equilibrium and incentive definitions. Replicating the paper’s strategic players as a continuum changes their strategic role; treating their types as a distribution instead changes the object being modeled.
So there is no qualifying anchor, and I can’t state a continuous problem as the continuous form of one of this paper’s computational results.
The strongest case against a ChoCo mirror is that the paper gives no computational result to mirror. Its Theorems 1, 5 and 6 concern which mechanisms and equilibria suffice for implementation. The model specifies finite players, states, evidence constraints and preferences, but no encoded family of computational instances, complexity measure, or algorithmic task. A continuous version could be mathematically interesting, but it would not fill the programme’s computational gap as posed.
The best repair would replicate the strategic parties into a population of evidence types and ask whether direct truthful reporting, static mechanisms, or the three-stage construction still suffice for an aggregate outcome. That changes the strategic problem. If the public outcome depends on the distribution of reports and evidence, an individual in a nonatomic population has measure zero, so their deviation leaves that outcome unchanged. The incentive tests that drive the finite-player results then become vacuous. Treating each type group as a bloc whose deviation moves its whole mass restores strategic force by changing the equilibrium concept; keeping pivotal parties as atoms retains the finite-player structure. Individualized outcomes could preserve pointwise incentives, but that leads to a new continuum mechanism-design model with its own outcome and measurability choices.
Theorem 1’s strongest mirror would be a direct-revelation result for continuum agents with hard evidence. Such a result may be worth proving, but it remains a structural characterization; the paper supplies no computational objective or input representation for it. Theorem 5’s static-versus-dynamic question has the same problem: in an aggregate-only nonatomic model, static sufficiency may follow simply because individual deviations cannot move the outcome. In a model with individualized consequences, the question may be substantive, but it is a new implementation theorem rather than a computational mirror. Theorem 6 is more tied to finite players: its construction uses a player-by-player order of evidence moves and selects the first player whose evidence conflicts with their report. A mass distribution does not supply that ordering or selection rule; adding one would be part of designing a new model.
So the negative case is strong on programme fit: none of the raised theorems is a computational claim about a population input, and the most natural continuum extensions change the strategic object or remain analytic. The broader claim that no continuum implementation project could be worthwhile is weaker; the paper does not establish that.
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.
