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 35 (read-only): does the approved concept turnaround describe OUR body?
|
|
#
|
|
# blender --background --python 35_silhouette.py -- <concept_front.png> <our_front.png>
|
|
#
|
|
# This decides how the turnaround can be used. If the silhouettes match, the concept renders could
|
|
# be projected onto the mesh as a texture source. If they do not, they are a style and tone
|
|
# reference only — and quietly projecting them would smear one body's paint onto another's shape.
|
|
# Widths are normalised by figure height, so framing and resolution cancel.
