Root cause was double: (1) segment_body's apply_scale scaled fork MESH
vertices but not each segment's embedded armature — the shared-skeleton
compositor relocates segments by bone name, so internally-inconsistent
segments exploded (child worst at 0.72x: head bone 0.35m above its mesh —
detached heads, spider arms); (2) thin/heavy were stale high-poly artifacts
from an older segmentation, missing seg_hips. Fix: apply_fork_scale bakes
mesh AND embedded armature via transform_apply (edit-bone poking shears
chains — first attempt proved it); new blender_rebuild_forks.py rebuilds
exactly the five from the owned UBC Source exports. All five now 19 low-poly
segments matching the healthy six.
QA on the real compositor (idle+walk, front+side): 5/5 coherent; healthy
controls unchanged. Q-060 answered at the extremes: 15/15 peasant-garment
Surface Deform binds on the forks, zero shrinkwrap fallbacks, no
bust-through — the 6-of-11 placeholder debt is paid (fork garment variants
included). Follow-up filed: T-1094 (child/teen composite at adult height —
pre-existing shared-skeleton normalization, not a regression).

Segmentation:
- Face-based exclusive assignment (no overlap, no caps needed)
- Hips split from torso (pelvis as own segment)
- Torso_upper independent (spine_03 + clavicle, not a variant)
- Clavicle moved from arm_upper to torso_upper
Hair pipeline:
- Solidify modifier (20mm) for scalp hair volume
- Normal recalculation before solidify for consistent direction
- Eyebrows/facial hair NOT solidified
- Fixed mask generation (was outputting black, now white)
Clothing pipeline:
- Solidify modifier (25mm) for clothing thickness
- Peasant shoes added from Fantasy pack
Tooling:
- convert_outfit.py with solidify support
- inspect_glb.py, check_hair_symmetry.py for debugging
- Segment reference distribution locked
- Q-063 footsteps VFX filed

- Fix stale 21→18 segment count in architecture doc, script docstrings,
and disk budget table (critical — both reviewers)
- Add average_m/README.md noting role as clothing reference body
- Add __main__ guards to diagnostic scripts
- Preflight-check all source paths in blender_process_bodies.py
- Document solid-white hair masks as v0.2 placeholder for multi-region
- Add fallback size comment for head mask generation
- Add bald_mask.png (1×1 black) for sidecar convention consistency
- Document child non-uniform scale rationale (Y=0.72 vs XZ=0.75)
