Interpretation: Thompson's claim has two parts: a geometric description of the cell (hexagonal prism, three rhombic basal facets meeting at the tetrahedral angle 109 deg 28 min) and a minimal-surface rationale. Only the geometric description is tested here; the minimal-surface statement is a theorem about the rhombic dodecahedron (and is in fact not the true minimum, as Toth 1964 showed), not an empirical matter. The test requires 3-D geometry of bee-built cell bases. The two Dryad datasets listed were identified as the only public comb datasets found on Dryad, Zenodo and figshare on 2026-10-31; their README files were read to determine whether they contain basal-facet geometry before any data were downloaded."; "Claim test of thompson1917-ch07-11: inconclusive, confidence 0"; ; prov:wasAttributedTo ; "Planned datasets: dryad-z8w9ghxmw-honeybee-adaptive-comb-construction-xrm, dryad-r4xgxd2f3-yang-2022-natural-comb-cell-orientation"; "claim-test/0.1.0"; "none"; "Pre-registered.
