# Character Transparent Slice Front Repair V2

## Status

- Review status: accepted as part of the v2-from-anchor transparent slice set.
- Scope: front full-body slice only.
- Repair reason: the first generated transparent slice set drifted away from the accepted v2 character anchor.
- Repair strategy: derive the front slice directly from the accepted v2 anchor board instead of regenerating a new person from text.
- Next gated action: completed by `character-transparent-slices-v2-from-anchor-review.md`.

## Execution Method

This repair did not use independent prompt-only generation.

Method:

1. Crop the front full-body standing figure from the accepted v2 anchor board.
2. Remove the light board background locally.
3. Save the result as a transparent PNG.
4. Preserve the old rejected v1 front slice as failed-trial evidence.

Crop box from the v2 board:

```text
(20, 104, 264, 835)
```

Local processing environment:

```text
C:\Users\wangq\.cache\codex-runtimes\codex-primary-runtime\dependencies\python\python.exe
```

## Validation

Validation result:

| Check | Result |
| --- | --- |
| Mode | RGBA |
| Size | 488x1440 |
| Four corners transparent | Pass: `[0, 0, 0, 0]` |
| Source identity | Directly derived from accepted v2 front figure |
| New-person generation risk | Avoided |

## Review Notes

Strengths:

- Identity matches v2 because the figure is cropped from v2 itself.
- Front face, glasses, hair, beard, coat, backpack straps, pants, and boots are preserved.
- No new prompt-only person was synthesized.
- Full body is retained.

Known limitations:

- Resolution is limited by the front cell inside the 16:9 anchor board.
- Some soft edge cleanup is image-processing based, not model-native transparency.
- This is a better identity anchor than the rejected v1 front slice, but not a high-resolution regenerated character render.

## Recommendation

Use this as the front transparent-slice candidate if identity fidelity is more important than maximum resolution.

After user approval, repair `side` using the same principle: derive or reference-bind from the accepted v2 anchor board first, rather than text-only regeneration.
