REGISTRY rewritten around the central rule: a character folder is born only when a body ships to ariki-game (<character>_base_v<NN> = ship ordinal). lena_nude dissolves accordingly: - characters/female/lena_base_v01/ — SHIPPED 2026-08-10: AccuRig GLB carrier, T-pose/rig FBX + JSON, previews, frozen README - characters/work/lena/ — the live lane: recipes 01-47 (incl. new 36-47: refill/sheets/clay/despeckle/musculature/spin/AccuRig export/graft/pose QC), masters (athletic_v04 blend + textures, accurig blend), lane-history README - hires_claude/hires_work intermediates (blends, logs, probes) pruned Supporting docs: AGENTS.md, working-files rule, rig-graft plan addendum, originals README, prune_lane.py.

# Stage 30b: repair face winding on the decimated GLB, in place.

# Decimation re-triangulates, and it reintroduced 61 inward-facing triangles on the 32k mesh —
|
|
# the same defect stage 25 cleared from the hires sculpt (1511 -> 10). A backfacing triangle
|
|
# renders black, so handing the retexture/re-atlas lane a mesh speckled with them would waste
|
|
# their pass. Same two-step remedy: propagate consistent orientation, then reverse whatever the
|
|
# non-manifold edges blocked (make_consistent cannot cross them). No vertex moves.
