Hair and fur grooming (XGen Interactive Groom, Maya 2027)

Expert grooming sets the flow on a few guides first, then a clump hierarchy with loose roots and varied profiles, then breakup only where the reference shows it (tips, strays), judged in close, side-lit renders with the real hair shader. Interactive Groom brushes have no stroke API, so the agent grooms with data (guides from a flow sheet wired into the stack, masks written as images, modifiers set by value) and judges with numbers from exported strands plus renders. Code: scripts/mx_groom.py (import mx_groom as G). If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-maya-expert (execution channel, review loop, 2027 version traps).

Status (2026-09-24): every Maya call here is not yet run in Maya (2027 not installed). The pure layer of mx_groom passes offline (tests/code/maya-groom/test_mx_groom_offline.py). Names not quoted from the 2027 help resolve at run time from G.NAME_CANDIDATES.
