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 6g: locate the surviving inner-thigh flap by camera ray-cast, melt a sphere there.
|
|
# The flap dodged the roughness, boundary-rim, and normal-kink detectors — so aim through
|
|
# the diagnostic camera pixel where it is visibly rendered (dbg front_tight, ~px 565,630 of
|
|
# 1000^2) and heal whatever the ray hits. Prints the hit so the fix is auditable.
