Effect score 48/100Substantive
Substantive. Sharpens a claim or proposes a test that could be run. Substantive and the strongest in this batch: a peer-reviewed case study of the kind open problem 6 asks for, read in depth, with the cost of independence quantified, and an apt transfer to the section 3.6 systematic. Held below major because its central proposal may be void in principle for the programme's own contrasts.
Progress to an answer: 1 of 100 — a small step. A small step, and the lower of the two numbers I weighed. It sharpens what a credible bound would have to show, but that sharpening may reduce to a limitation section 1's third settled result already implies, and no model-independent route has been shown to exist for either contrast. See the running chart.

Answers open problem 6 of section 9, which asks for one properly bounded archaeological or geological case study, and proposes a transferable step the programme's own protocols lack: derive the anomaly a second time by a route that does not take the model it was first measured against as an input. The source is strong for this track, an open-access Nature Communications paper read as far as its Methods, and the contribution reports two unrelated detector technologies agreeing on a corridor's dimensions, a recovered injected void, six muon flux parametrizations tested, then a geometry-free tomographic reconstruction in which the structure reappears smeared over about five metres of height against centimetre-level parameters from the model-based route. Recording that cost is what makes the proposal honest rather than free. The transfer is apt: section 3.6's unexplained systematic has as its leading hypothesis that the two arms differ in a way matching the final ideal output does not capture, and that is a model-adequacy problem no further null simulation inside the same model can settle. Nothing in the foundation changes. Its main weakness is one it raises but does not press: section 1's third settled result already says classical simulation cost is not a function of any fixed finite set of state properties, and Session 005's cheap-frame example makes cost frame-relative, so for these contrasts there may be no model-independent fact to re-derive at all, which would make the proposal inapplicable rather than deferred.
Next step
Do the paper exercise it asks for, and expect a negative. For the tensor-network contrast, try to write down a certificate of separation that does not use the frozen toolbox, reading it against section 1's third settled result and Session 005's example of a state that is maximally costly in one frame and an exact product state in the frame its own construction supplies. If cost is frame-relative in that way, no frame-free certificate exists, and the honest output is a sentence in section 3.7 recording that neither bound carries, or can carry, a derivation independent of the algorithm class it was measured against. That is a permanent instrument limit rather than an open task, and it is worth more than leaving the item in section 9 to be attempted again.
AI-assisted editorial assessment · · This assessment can be challenged; it is separate from the contributor’s claim.
Almost every anomaly this programme works with is a gap between what was measured and what a model said to expect, which leaves open the possibility that the model, not the world, produced the gap. This open-access paper closes that possibility for a void inside the Great Pyramid, and it shows what doing so costs. Two teams using unrelated detectors measured the corridor to a few centimetres by comparing data against a three-dimensional model. The same team then rebuilt it tomographically with no geometry supplied at all, so the shape of the pyramid became an output. The void reappeared, but smeared over about five metres of height. That trade is the number the programme currently has no estimate of.

Reading guide, not a summary of the contributor’s claim.
The proposal fails if a model-independent route is unavailable in principle for the programme's own contrasts, rather than merely expensive. That is a real possibility and it is what should be checked first: the RCC-A2 design certifies that one arm of each pair is cheaper to simulate than the other, and if every available certificate is built from the same frozen toolbox that the host response is being measured against, then no second route exists and the proposal should be recorded as inapplicable rather than deferred. It also fails if the model-independent route, once costed, degrades the certified separation below the point where any bound can be stated, since a check that cannot resolve one doubling of bond dimension cannot corroborate a bound quoted per doubling. On the source side the specific claim fails if the tomographic reconstruction turns out to depend on the geometry after all, for instance through the open-sky simulation used to convert measured absorption into opacity, which is an input the authors describe and which is not itself geometry-free. A demonstration that this step carries the reconstruction would remove the example without touching the general proposal, which would then need a different worked case. No measurement, reanalysis or simulation was carried out for this contribution and no figure below is mine.
