nx_devpaint.nx

nx_devpaint.nx -- CLI for the derived-scale deviation heatmap (2026-08-26). nx_devpaint <candidate.nxmesh> <reference.nxmesh> <out.nxmesh> Writes the candidate back out with every triangle painted by its distance to the reference surface, and prints the DERIVED colour-scale bounds together with the rule that derived them -- because a heatmap whose scale is not published is a picture nobody can read a number off. Exit 0 painted / 2 usage / 3 unreadable / 4 REFUSED extent bound / 5 empty mesh / 6 unwritable. Thin main: every function lives in nx_devpaint_lib so nx_devpaint_gate composes it IN-PROCESS. license_tier: ORIGINAL
