v2.6.1

Earlier version of the analysis for Edwards (2026), "Constraints on the Origin of the Asteroid Belt's Compositional Gradient from Debiased Taxonomic Data", which cites v2.6.3. v2.6.3 changes only how figures are drawn (italic variables, Fig. 12's legend); its numbers are identical (see its notes).

Drawing changes only, from the paper's formatting audit:

paper	file	change
Figs. 2, 4, 8, 11	fig5_circularity.png, fig1_c_fraction_vs_a.png, fig7_crossover_fits.png, fig4_dark_fraction_albedo.png	legend moved outside the axes, where no line crosses it
Fig. 9	fig3_orbital_excitation.png	KS p-values printed as in Table 5 (0.030, 0.0060)
Figs. 3, 7	fig11_sample_flow.png, fig2_mass_by_zone.png	"analyzed", "all classified bodies"
11 figures	every figure with a distance axis	astronomical unit written "au" (AAS / IAU style)

summary.json is identical to v2.6.0's apart from software.beltgradient; no random draw changes. fig0_completeness.png, fig9_robustness.png and fig12_albedo_by_group.png are byte-identical. The input is still AsteroidCatalog data-2026-09-29c (data contract 1.8.1).
