# WBV2-P16-001: select_paint_capability_batch

- task: WBV2-P16-001
- parent: WBV2-P16-000
- status: in_progress
- gap: capability:SCULPT.PAINT_ATTRIBUTES
- ownerFamily: PARITY
- targetImplementationClass: LOCAL_BOUNDED

## 目标

Select one deterministic vertex-color and weight-paint behavior batch from source and inventory evidence.

## 输入与范围

- Focused source: `tests/golden/WBV2-P0-002/parity-map.json`
- Existing source receipt: `tests/golden/WBV2-P4-003/sculpt-report.json`
- Production API: `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`
- Production entrypoint: `node tools/web/generate-wbv2-paint-selection.mjs --write`

## 验收

- source commands are present and hash-bound
- existing paint evidence is reused read-only
- candidate remains representative rather than full-family completion
- malformed, hash-drift, unsupported, or false-completion input keeps in_progress
- `node tools/web/check-task-context.mjs --task WBV2-P16-001 --write`

## 交付与回滚

- Reports: `tests/golden/WBV2-P16-001/`
- Status: `docs/status/WBV2-P16-001.md`
- Manifest: `tests/golden/WBV2-P16-001/manifest.json`
- Rollback: restore P16-000 as queue parent.
