v2.6.3

The release the paper cites. It changes only how figures are drawn: results/summary.json is identical to v2.6.1's apart from the version. It reads the AsteroidCatalog release data-2026-09-29c (data contract 1.8.1).

It includes v2.6.2 (#15), which was merged but not released on its own.

Figures

• Italic variables, as the paper sets them: semimajor axis $a$, diameter $D$, absolute magnitude $H$, sample size $n$, $P(\mathrm{C} \mid a)$, KS $p$, proper $e_\mathrm{P}$ and $\sin i_\mathrm{P}$ (#16).
• Upright label subscripts: $H_\mathrm{c}$, $D_\mathrm{c}$, $T_\mathrm{eq}$, $p_\mathrm{V}$, $a_\mathrm{P}$, $i_\mathrm{P}$ (#15).
• Fig. 12: the legend moves below the plot, where the $p_\mathrm{V} = 0.30$ line no longer crosses it.
• Fig. 10: the Koronis and Nysa–Polana labels move clear of the 5:2 line and the axis.
• Figs. 2 and 11: no doubled parentheses in the legends. Fig. 8: the lower panel gives its diameter limits in km.

Figs. 1 and 7 are byte-identical to v2.6.1's.

Repo

• README: the release history is now a list under Releases, with stale figure numbers fixed, IPW named as in the paper, and "au" and American spelling.
• Version 2.6.3 in __init__.py and CITATION.cff.

Checks

• Real-input run: summary.json differs from v2.6.1's only in software.beltgradient.
• pytest: 31 passed. pytest -m slow: passed.
• CI: 5/5 on #16.
