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 45: export v10 as an AccuRig-loadable FBX.

# NO RIG BAIT. `tools/rigbait_decimate.py` exists because the source GLBs are 1.9 M tris and
|
|
# AccuRig refuses them outright. v10 is 62,929 tris — under the lane's own 78k bait budget — so it
|
|
# goes in whole. That also deletes the decimated->full-res weight transfer, which is exactly where
|
|
# the July lane's finger mangling happened.
|
|
#
|
|
# SCALE. Per `.agents/plans/rig-graft-lane-2026-08-04.md` the GLB never changes size; only the
|
|
# disposable FBX does. AccuRig misplaces joints on a ~0.98-unit body, so this exports at a
|
|
# human-scale height and prints the factor to undo on the way back. The male lane settled on
|
|
# 1.700 m and on scaling to HEIGHT, not to the pelvis.
|
|
#
|
|
# NO MATERIALS. The lane's hard rule is that visual data is never sourced from FBX — the male FBX
|
|
# came back with mislabeled and duplicated textures. AccuRig only needs the surface, so nothing
|
|
# visual is sent and nothing visual comes back; the GLB keeps its own atlas.
