Why no mirror

None of the named results asserts an algorithm, computational hardness, or another qualifying computational result. The proposed finite-support location model would introduce a new input regime rather than mirror a computational finding in this paper.

fails bit a — no named computational result to mirror

What the mirror covers

Propositions 3.1 and 3.3 and Result 2.4 are analytic nonexistence or characterization results; none provides a computational result to mirror.

The case FOR (proponent)

The strongest foothold for a continuous mirror is that the paper already gives a clear mass-based model: residents are locations in \(\mathbb{R}^2\), mass is Lebesgue measure, and the decision is how to partition the population into jurisdictions and assign access fees. But that is also the difficulty: simply replacing individual citizens with mass would restate the paper’s model, not produce a new mirror.

I can’t supply a qualifying anchor. The closest results are Proposition 3.1, proved here, which says that under Assumptions A.1–A.6 no secession-proof allocation exists; and Proposition 3.3, also proved here, which gives \(\delta^*\approx 0.0019\) and says the allocation set at that threshold contains only the Rawlsian allocation. Result 2.4 characterizes efficient partitions as identical regular hexagons, drawing on established geometric results. These are existence and characterization results, not claims that a problem is in P, NP-hard, FPT, or otherwise computationally classified. The paper has no named computational result of the required kind.

A possible new research direction would give the spatial population as finitely many rationally weighted location types, then ask for the minimum subsidy and a cost allocation stable against every seceding subpopulation. That would make a concrete computational problem, but it generalizes the paper’s setting rather than mirroring one of its computational findings. The paper’s exact uniform-plane model already has its stability threshold characterized analytically, so I would not present this as an anchor-based positive case.

The case AGAINST (opponent, writing after the proponent)

The proponent names no surviving computational anchor. Proposition 3.1 establishes nonexistence, Proposition 3.3 gives the fixed threshold \(\delta^*\approx0.0019\) and identifies the unique allocation at that threshold, and Result 2.4 characterizes efficient partitions geometrically. None classifies an algorithmic problem by complexity. The proposed question about computing subsidies for finitely many rationally weighted locations may be worthwhile, but it adds a variable input distribution that this paper does not study; it is not a mirror of a computational result here.

There is a further obstacle to a faithful mirror: the paper already makes the population continuous. It identifies citizens with locations and uses Lebesgue measure on \(\mathbb{R}^2\). For that exact uniform-plane model, the hexagon geometry and subsidy threshold are characterized analytically; varying \(g\) changes the scale, not the threshold. Asking for computational complexity on this fixed family offers little input to vary, while asking about arbitrary measurable allocations first requires an encoding the paper does not provide. A finite-support location model would supply such an encoding, but it replaces the paper’s uniform spatial economy with a different problem.

The negative case is strongest against these proposed anchors, not against every adjacent research direction. Repeated residents at a finite set of locations could be a sensible high-multiplicity regime, and studying the complexity of stability there might be valuable. The limitation is that this would be a new computational extension of a paper whose population is already continuous—not a continuous mirror of one of its computational results.

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.
