- 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.

Purpose
TBD - created by archiving change standardize-blender-object-coordinates. Update Purpose after archive.
Requirements
Requirement: Depth Symmetry mirrors across the canonical Y axis
O Image Cutout Symmetry SHALL 在 canonical Blender 对象坐标中沿 Y 轴镜像，即镜像面为 Y=0 的 XZ 平面。镜像前后的几何 MUST 在最终旋转前保持 (x, y, z) 与 (x, -y, z) 的对应关系。
Scenario: Canonical mirroring
- WHEN 上游 Depth Cutout 输出 canonical 几何并连接
O Image Cutout Symmetry - THEN 对称节点先按 Y 轴删除越界半侧并镜像到另一侧
- AND Fill Sides 开启时沿 Y 方向连接对应边界
Requirement: Final symmetry axis is X with Z up
O Image Cutout Symmetry SHALL 在 canonical Y 镜像完成后执行绕 Z 的固定旋转，使对称轴从 +Y 变为 +X，并保持 +Z 为 up。最终结果 MUST 在本地坐标中关于 X=0 对称。
Scenario: Default Depth Symmetry result
- WHEN 用户通过 Depth Symmetry 入口生成对象
- THEN 最终 evaluated local geometry 关于
X=0对称 - AND 最终 Z 范围反映图片 up 范围
- AND 对象保持 up=Z
Requirement: Depth Symmetry final front direction may change
Depth Symmetry 的最终朝向 SHALL 允许 canonical front -Y 随最终 yaw 旋转变为 -X。系统 MUST 不要求 Depth Symmetry 最终继续满足 front=-Y。
Scenario: Final front direction
- WHEN 使用把 +Y 映射到 +X 的最终 yaw 旋转
- THEN canonical front 方向 -Y 映射为 -X
- AND up 方向 +Z 保持不变
Requirement: Depth Symmetry path has no Cutout Depth Axis
Depth Symmetry 创建流程 SHALL 不设置或依赖 O Image Depth Cutout 的 Depth Axis。所有最终轴向语义 MUST 只由 O Image Cutout Symmetry 承担。
Scenario: Create Depth Symmetry modifiers
- WHEN 用户通过 Depth Symmetry 入口创建对象
- THEN 上游
O Image Depth Cutout不包含Depth Axis输入 - AND 上游 Cutout 输出 canonical +Y 深度结果
- AND
O Image Cutout Symmetry决定最终 X 朝向
