Maya retopology and UVs

Expert retopology is a loop plan with the fewest polygons that still deform: landmarks first, rings around eyes and mouth, three loops per joint, poles where nothing moves, a bend test that says whose fault a bad crease is. Expert UVs spend texels where the camera looks, at a density derived from the closest shot, with padding that survives mips. Without a mouse the agent reuses approved topology, builds from data, and measures then renders every stage. 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). Toolkit: scripts/mx_retopology_uv.py (import mx_retopology_uv as RU), built on mx_audit, mx_review and mx_run.

Status (2026-09-24): every Maya call is not yet run in Maya (not installed); 99 pure and 40 fake-Maya checks pass offline. First run tests/code/maya-retopology-uv/run_all.sh, then fix what job_probe_commands reports.
