Multiview Constraint Solver

多视图约束求解器

Use this before another rebuild when references disagree. A renderer cannot make one rigid mesh satisfy mutually incompatible orthographic dimensions unless you allow view-specific cheats.

当参考视图存在冲突时，在再次重建前使用本工具。除非允许针对特定视图做取巧调整，否则渲染器无法让单个刚性网格满足相互矛盾的正交尺寸要求。

Workflow

工作流

Normalize every reference view into a common axis contract:
- front: width X, height Z;
- side: depth Y, height Z;
- top: width X, depth Y;
- back: width X, height Z.
Measure visible body bboxes, not labels/background/aura unless they are part of the model contract.
Compare shared axes:
- front width vs top width;
- front/back height vs side height;
- side depth vs top depth.
If ratios differ beyond tolerance, write a conflict report and select a policy:
- ```
front_side_canonical
```
  : front brand read and side depth/height are authoritative;
- ```
front_top_canonical
```
  : front brand read and top footprint are authoritative;
- ```
corrected_templates_required
```
  : no rigid rebuild should claim final fit;
- ```
view_specific_cheats
```
  : separate camera/view variants allowed, not one rigid asset.
Feed the chosen policy into
```
fit-repair-optimizer
```
before any geometry, UV, or lighting work.

将所有参考视图标准化为统一的轴约定：
- 前视图：宽度X轴，高度Z轴；
- 侧视图：深度Y轴，高度Z轴；
- 顶视图：宽度X轴，深度Y轴；
- 后视图：宽度X轴，高度Z轴。
测量可见主体的bbox，不包含标签/背景/光环效果，除非这些属于模型约定的一部分。
比对共享轴的尺寸：
- 前视图宽度 vs 顶视图宽度；
- 前/后视图高度 vs 侧视图高度；
- 侧视图深度 vs 顶视图深度。
如果比例差异超出容差范围，生成冲突报告并选择一种策略：
- ```
front_side_canonical
```
  ：前视图品牌标识读数和侧视图的深度/高度为权威标准；
- ```
front_top_canonical
```
  ：前视图品牌标识读数和顶视图占地面积为权威标准；
- ```
corrected_templates_required
```
  ：任何刚性重建都不能宣称完全适配，需修正模板；
- ```
view_specific_cheats
```
  ：允许使用不同的相机/视图变体，而非单一刚性资产。
在开展任何几何、UV或光照工作之前，将选定的策略输入到
```
fit-repair-optimizer
```
中。

Hard gates

硬性规定

Do not restart modeling until canonical policy exists.
Do not treat top-view aura/context as body depth.
Do not average contradictory dimensions unless the user explicitly asks for an approximate stylized compromise.
Record part-count disagreements separately from bbox disagreements.

未确定规范策略前，不得重启建模工作。
不得将顶视图的光环/背景元素计入主体深度。
除非用户明确要求近似的风格化折中方案，否则不得对相互矛盾的尺寸取平均值。
部件数量不一致的问题需与bbox不一致的问题分开记录。

Script

脚本

```
scripts/view_constraint_report.py
```
reads a JSON file of per-view body bboxes and emits shared-axis compatibility and a suggested canonical policy.

```
scripts/view_constraint_report.py
```
：读取包含各视图主体bbox的JSON文件，输出共享轴兼容性分析及建议的规范策略。
