### §11 addendum — vertex baker PRODUCTIONIZED (2026-07-19 night)
Wired and validated in BOTH pipelines:
- `vendor/trellis-mac` @ 55fdd7b: `TRELLIS2_BAKER=vertex` env mode in
generate.py (Metal + kdtree paths untouched; sentinel-gated).
- Jourloy fork @ 746e727 (pushed to monster/trellis-2-mrp-mlx): CLI
`--baker vertex`.
E2E validation (anatomy, seed 42, 1024-cascade, uncapped density):
**130.0s total, bake 1s**, 232s wall, 20.8GB peak — full 2.79M-face
vertex-colored GLB, ZERO dark patches, best local quality yet
(`render_vprod_front.png`). vs Metal-bake baseline: same speed envelope,
quality gap closed for albedo. Not yet carried: metallic/roughness maps
(vertex colors are albedo-only) — MR needs the UV path (Option B) or a
COLOR_1 convention. MESHGOD finish-farm verts→texture bake = the
remaining Option-A step for game-budget assets.
