nan 076a8c90f1 Add specifications for two-times upscale and unified depth plane features
- Introduced the two-times upscale specification detailing requirements for unified output, fixed model presets, arbitrary dimensions, and consistent job behavior.
- Added scenarios for existing models, repeated upscale, and handling of alpha preservation.
- Created the unified depth plane specification outlining geometry modes, stable interface, and asset evaluation.
- Defined scenarios for mode switching, relief and camera preservation, and validation of delivered assets.

1. RGB 合成修正

  • 1.1 复核有效投影、最底层选择和公共采样入口,保留已有几何行为。
  • 1.2 以底层原始 RGB 初始化,前景逐层按 Alpha 叠加;Alpha 独立沿用原公式,源外扩色使用最终颜色。

2. 验证

  • 2.1 更新半透明预期,补充三层合成、白色底图上的前景渐变、预乘插值和单源原始 RGB 测试。
  • 2.2 验证实际 Packed Image 在 Mask Add 后保留前景到白色的连续渐变。
  • 2.3 运行定向与全量测试,校验 OpenSpec;不改产品文档,不构建产物。

验证结果

  • 定向测试:51 passed;全量 uv run pytest:440 passed。
  • 实际 Packed PNG 与 Mask Add 结果均验证了前景到白色的连续 RGB 渐变,Alpha 合成保持独立。
  • 未做 Blender 视口人工验收,未构建产物。
