Theorem 2 characterizes a property of outcome functions but gives no algorithm, complexity bound, or computational formulation used to compute one. The proposed feasibility problem over fractional skill supplies introduces a new value model and incentive constraints, so it is not a continuous analogue anchored in a computational result of this paper.
fails bit a — no named computational result to mirror
No computational result is mirrored; the proposed feasibility problem is newly defined, while the compact representation and nucleolus results have no computational counterpart.
I can make a plausible positive case for a *model*, but not an anchor-based case under your rule. The paper has no numbered result asserting that a computational problem is in P, hard, FPT, or similar. Theorems 1–7 are proved here, but they establish properties of outcome functions and the anonymity-proof nucleolus. In particular, Theorem 2 characterizes anonymity-proof core membership using no-hiding and non-blocking conditions; Theorems 4–7 establish uniqueness, existence, core membership, and symmetry for the nucleolus. None analyzes the complexity of computing or testing those objects. The paper also gives no encoding that it then uses to compute one. So there is no qualifying named computational anchor.
The most plausible regime for a mirror is a large market of firms, each contributing one uniquely named but interchangeable skill token from a small set of capability classes. The number of firms could be very large while the number of classes stays small. The paper itself allows identical skills to receive different names (Definition 1, footnote 2), so this regime fits its skill model better than treating a named skill as something many agents literally share.
A concrete, but unanchored, candidate is *Continuous Anonymity-Proof Core Feasibility*. The input would be a finite set of skill classes \(K\), rational supplies \(q^0\in\mathbb{Q}_{\ge 0}^K\), and a rational piecewise-linear coalition-value function \(v\) on \([0,q^0]\). A solution would be payoff functions \(\pi_k(q)\), represented by finite rational piecewise-affine formulas for every reported supply \(q\in[0,q^0]\), satisfying, for every \(q\),
\[ q\cdot\pi(q)=v(q), \qquad r\cdot\pi(q)\ge v(r)\quad\text{for every }0\le r\le q, \]
and, for every \(0\le z\le y\le q\),
\[ z\cdot\pi(q-y+z)\le y\cdot\pi(q). \]
These are the continuous versions of efficiency, non-blocking, and the no-hiding condition. Theorem 2 motivates the question; it does not establish a result about this continuous problem. I would leave its complexity open: a finite separation method might make it tractable, while the continuum of coalition masses and reports could create new hardness. There is no sound basis here to classify it in the programme’s trichotomy.
This is a computational question about a continuous population and a value-division rule, so it is in scope. The soft spot is also substantial: the paper’s compact synergy representation describes values over discrete sets of named skills, not fractional skill supplies. Choosing the fractional value function \(v\) is a genuine model extension, and extending the nucleolus would be still less canonical because its excess vector ranges over coalitions. The core-feasibility question is the more credible lead, but without a qualifying anchor this paper cannot support the requested result-based positive case.
The proponent has no qualifying computational anchor. Theorems 1–2 give conditions for anonymity-proofness and core membership; Theorem 3 establishes a compact representation; Theorems 4–7 establish properties of the anonymity-proof nucleolus. None states a complexity result for computing or testing a solution. The paper’s representation-size discussion also gives no algorithmic problem or complexity classification. So the proposed feasibility problem is unanchored: Theorem 2 may suggest it, but it does not establish a computational question to mirror.
The proposed skill-mass model also loses information that the paper’s incentives use. The paper values sets of distinct skills, and its no-hiding condition concerns the skills held by an individual agent. A vector \(q\) of aggregate class supplies does not say which skills belong to the same agent. To aggregate firms into capability classes, one must assume symmetry among their skill tokens; otherwise the characteristic function \(v\) can distinguish tokens in ways that \(q\) erases. A more faithful population input would track the distribution of complete agent types, including their skill bundles. That would be a substantial new model of the mechanism, rather than a continuous version of the paper’s input.
The proposed no-hiding inequality exposes the difficulty. If \(y\) is one agent’s skill mass, a positive \(y\) makes that agent macroscopic, which sits uneasily with a high-multiplicity population. If \(y\) is a mass of agents, the constraint concerns coordinated deviations, whereas the paper’s condition concerns one agent hiding skills. If individual mass tends to zero, the deviation barely changes \(q\); preserving the incentive question requires a new per-agent limit condition and utility scaling. The continuum nucleolus has a related gap: extending the paper’s lexicographic ordering over a finite excess vector to a continuum of coalitions requires a new selection criterion.
A repaired model over bundle types, with a mass-based value function and carefully scaled individual incentives, could be a worthwhile research project. The honest negative case is weaker as a claim that every such project lacks value. It is stronger on the question asked here: that project would introduce its own computational problem and modeling choices, with no named computational result in this paper for it to mirror.
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.
