"""T06-a 方案维度解析：去重、刻度冲突与呈现判定。

依据：docs/v2/14-experience-loop.md §5、03-detailed-design.md §9.2；
BR-28 / E-20 / AC-29 / AC-44。

三条不可妥协的规则：
1. **同 ID 必须语义一致**：标签、量纲（scale_id/version）、刻度层级任一不同即
   **拒绝合并**并报冲突，绝不让模型临时猜一个（BR-28）。相同定义只保留一份。
2. **异刻度不强行归一化**：不同刻度的维度不得共用雷达，改为分面展示（14 §5）。
3. **不默默丢失关键项**：呈现判定返回的 radar / listed / hard_block 三组并集
   必须等于全部维度；任何维度都要出现在某一组里（AC-44）。
