The numbered results establish robustness conditions for the G.V.A. and impossibility of satisfying mechanism properties; none asserts that an object can be computed or classifies computational difficulty. Criterion (a) therefore fails before a continuous-population question can be attached to a named computational result.
fails bit a — no named computational result to mirror
Theorems 1 and 2 give robustness results, while Theorems 3 and 4 give mechanism-existence impossibilities; none is an eligible computational anchor.
I can’t make a compliant positive case under the anchor rule. The paper has no named computational-complexity result: Theorems 1 and 2, proved here, characterize when the G.V.A. is robust against false-name bids; Theorem 3, proved here, rules out a mechanism satisfying individual rationality, Pareto efficiency, and incentive compatibility in all cases; Theorem 4 states the analogous impossibility for multiple items. None classifies a problem as tractable or hard.
A continuous population of valuation types could motivate a new mechanism-design question, but presenting one as a mirror of a computational result here would overstate the paper’s contribution. There is therefore no eligible anchor—and no honest way to supply the requested continuous problem per anchor.
The proponent raises no anchors, and that is the strongest case against a continuous mirror here. The paper’s Theorems 1 and 2 characterize when the generalized Vickrey auction is robust against false-name bids; Theorems 3 and 4 give mechanism-existence impossibilities. None states a computational complexity result. A continuous restatement of Theorems 1 or 2 would still be a robustness characterization, and one of Theorems 3 or 4 would still be an axiomatic impossibility. Those are outside this programme’s computational scope.
The best computational question to extract would be: given a distribution of other bidders’ valuation types and one bidder’s true valuation, find the false-name reports that maximize that bidder’s gain. But this adds a computational objective the paper does not study. It also exposes a deeper mismatch: false-name manipulation depends on knowing that several submitted identities belong to the same principal, so their payments and allocations can be combined when measuring that principal’s utility. A distribution over bidder types does not preserve this ownership link. If the manipulating bidder becomes infinitesimal in a population-scaled market, its effect on the aggregate allocation can vanish. Keeping it as a positive-mass atom preserves its identity and makes the model a hybrid; treating an entire mass as one coordinated principal instead turns the question into coalition manipulation.
Those hybrid or coalition models could be worthwhile research in their own right. They do not supply a continuous mirror of a named computational result in this paper. The negative case is therefore strong as a verdict under ChoCo’s stated criteria, though it cannot rule out every useful adjacent model or hybrid formulation.
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.
