reorg(characters): ship-time folders — lena_base_v01 ships, lane moves to work/lena
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 13: heal the garment-BOUNDARY dig-ins. Every stomach/waist line sits where an old
|
||||
# garment mask edge was: the sculpt replaced the region INSIDE the mask, but anchored its
|
||||
# membrane on the rim — exactly where the waistband/leg-hems/bra-band dug into the body, so
|
||||
# the dig-in ring survived as the boundary condition. Free a band STRADDLING every garment
|
||||
# boundary (grow-out XOR shrink-in), plus slit seams on unmoved skin (0.5 mm mapping), and
|
||||
# solve the rim-anchored membrane across it.
