# Isabel_Profile HANDOFF

Written: 2026-07-03 17:28 KST

## Request
- Source instruction: `Isabel_Profile/이미지작업_의뢰서.md`
- Generate all 17 rig part images for Isabel_Profile.
- Stop by 17:50 and save `HANDOFF.md`.

## Completed
- Generated 17 PNG outputs in `Isabel_Profile/03_Assets/Parts/Images/`.
- All outputs are fixed 520x900 canvas, RGBA PNG, transparent corners/background.
- `isabel_part_master_apose.png` is saved as the recomposed result of the 16 part PNGs.
- 16 part recomposition validation passed with `recomposeDiffPixelsGt2 = 0`.

## Output Files
- `isabel_part_master_apose.png`
- `isabel_part_head.png`
- `isabel_part_neck.png`
- `isabel_part_chest.png`
- `isabel_part_pelvis.png`
- `isabel_part_upperarm_r.png`
- `isabel_part_forearm_r.png`
- `isabel_part_hand_r.png`
- `isabel_part_upperarm_l.png`
- `isabel_part_forearm_l.png`
- `isabel_part_hand_l.png`
- `isabel_part_thigh_r.png`
- `isabel_part_shin_r.png`
- `isabel_part_foot_r.png`
- `isabel_part_thigh_l.png`
- `isabel_part_shin_l.png`
- `isabel_part_foot_l.png`

## Method
- Used existing project RGBA library assets for speed:
  - Body source: `Isabel_Profile/03_Assets/Library/CoarseParts/Club/isabel_body_club_apose.png`
  - Head source: `Isabel_Profile/03_Assets/Library/Heads/isabel_head_wave.png`
- Normalized body/head to a 520x900 full canvas.
- Split body pixels into rig parts with geometric masks.
- Saved every part at original canvas origin, no cropping.
- Saved contact sheet and validation report under `tmp/imagegen/`.

## Verification Artifacts
- Contact sheet: `tmp/imagegen/isabel_profile_parts_contact.png`
- Recomposition preview: `tmp/imagegen/isabel_profile_parts_recomposed.png`
- Validation report: `tmp/imagegen/isabel_profile_parts_report.json`
- Build script: `tmp/imagegen/build_isabel_profile_parts.py`

## Notes / Limitations
- This pass prioritized finishing all required files before the 17:50 stop time.
- The parts are deterministic slices from existing Isabel club/head assets, not 17 fresh model generations.
- The master and all parts line up exactly because the master is generated from the 16-part recomposition.
- Some part boundaries are geometric approximations. If higher-quality rig deformation is needed, refine masks or generate a cleaner native A-pose with more separation.
