The paper has no named computational result: its unnumbered main theorem and Lemma 1 characterize secession-proof allocations and efficient partitions, but make no algorithmic or complexity claim. The finite-support problem is a coherent follow-on, yet it cannot supply the missing computational result to anchor a mirror.
fails bit a — no named computational result to mirror
No named computational result is covered. The proposed finite-support problem extends the paper’s secession-proof allocation model.
The strongest honest positive case is a follow-on computational question, not a mirror anchored in a named computational result of this paper. The paper already models a continuum population: citizens are distributed over \(\mathbb R\) by Lebesgue measure, and both jurisdictions and cost allocations are defined over that population. Its main result, printed simply as “Theorem:” with no number, characterizes the unique secession-proof arrangement in the uniform-line setting: equal intervals of length \(2\sqrt g\) with the Rawlsian allocation. Numbered Lemma 1 characterizes efficient partitions. Neither it nor the other numbered lemmas asserts a complexity result. So there are no eligible anchors, and no per-anchor continuous problem to hand to a prover under your criteria.
A plausible computational extension would use a large population concentrated at a small number of settlement types. Let the instance be rational locations \(z_1<\cdots<z_\tau\), rational masses \(\mu_i\) summing to \(1\), and fixed facility cost \(g>0\). A type is a location; its mass represents residents with identical transportation costs. Ask whether one can partition the ordered types into contiguous jurisdictions, choose each facility’s median location, and assign a common contribution \(x_i\) to each type in its jurisdiction so that every jurisdiction balances its facility cost, \(\sum_{i\in J}\mu_i x_i=g\), and no coalition can benefit by seceding. Precisely, for every coalition vector \(q\) with \(0\le q_i\le\mu_i\), its current burden must satisfy
\[
\sum_i q_i\bigl(|z_i-\ell_{a(i)}|+x_i\bigr)
\le
\inf_{\ell\in\mathbb R}\sum_i q_i|z_i-\ell|+g,
\]
where \(a(i)\) is the assigned facility and \(\ell_{a(i)}\) its location. The output would be such an assignment and contribution schedule, or a certificate that none exists.
This has a credible high-multiplicity scenario: a large catchment with many residents at a relatively small number of settlements, sharing locations and facility costs. It also asks about the paper’s underlying secession-proof allocation problem, rather than an encoding. But it is an extension beyond the paper’s uniform population on the whole line, not one of its results. The authors’ cited work on other population distributions makes the extension plausible; it does not supply the missing computational anchor or determine whether the problem is tractable, transfers discrete hardness, or is continuum-specifically hard. That absence is the case’s weakest point—and, under the requested anchor rule, decisive.
The strongest case against a mirror is that the paper has no computational result to anchor one to. Its main, unnumbered theorem characterizes a secession-proof allocation in an already continuous society; Lemma 1 characterizes efficient partitions. Neither gives a complexity result, an algorithm, or a computational problem with an input encoding. For the paper’s uniform-line setting, the theorem already gives the answer in closed form.
The proposed finite-support problem is a sensible high-multiplicity scenario: many residents can share a location and costs, and the rational masses give a finite input. But it is a follow-on computationalization of the model, not a continuous mirror of a result in this paper. It replaces the uniform population on the whole line with arbitrary finite support and asks a new algorithmic question. The paper’s cited work on broader distributions shows that the economic model has been studied beyond the uniform case, but, as far as this text establishes, it does not answer the computational question.
That distinction supports a negative verdict only if “mirror” requires an anchor among the paper’s own computational results. It does not defeat the proposed extension as worthwhile programme work: the finite-support question remains coherent and plausibly recognizable to the authors. I can’t honestly make the universal case that no scenario yields a worthwhile question. The negative case is strong on the absence of an eligible anchor and weak against the better follow-on 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. 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.
