v2.5.0

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. v2.6.0 adds three figures and the numbers behind them; everything here is unchanged in it (see its notes).

Figures at print size. Every figure is now drawn at the width it is printed: one column (3.31 in) or the full text width (7.02 in), at 300 dpi with 6–7 pt type, so its labels are legible on the page. Before, they were shrunk to about 4.5 pt. Other changes:

• Legends sit clear of the data, resonance names are on a top axis, and no figure has a title that repeats its caption.
• The stacked composition (Fig. 3) is drawn as the 0.1 AU bars it is computed on.

The figures draw the same random numbers in the same order as before, so no result changes.

Four new figures, drawn from computed results only:

paper	file	shows
Fig. 4	fig6_size_distance_map.png	C/(S+C) of the family-collapsed, completeness-weighted sample in bins of semimajor axis and diameter
Fig. 6	fig7_crossover_fits.png	the fitted logistic transition of all four samples, with each a50 and its 16–84% interval
Fig. 8	fig8_proper_elements.png	the bodies of the orbit test over the density of all family members, main families named
Fig. 10	fig9_robustness.png	every per-zone carbonaceous fraction the paper reports, samples and checks together

summary.json. The new size_distance_map block records the Fig. 4 cells and their counts. Every other value is identical to v2.4.0's apart from the version. The input is still AsteroidCatalog data-2026-09-29c (data contract 1.8.1).

New API: figures.size_distance_map, crossover_fits, proper_element_map and robustness_summary, gradient.size_distance_grid, and figures.COL_W / FULL_W. pipeline.FIGURE_FILES now maps each file to its paper figure number.
