exp+fix: 轮次31——确定界连续认证抓到段内碰撞，但单段P50 22.9ms进不了20ms；自适应cap收益经交错复测撤回

Browse Source 
- Kin.cert_lever 用三角不等式给全姿态位移界（替代 JS 随机采样×1.05），界量级 5.93–48.86 mm/整步
- Kin.certify_segments 批量前沿二分+每根查询预算：48 固定段中预算32判安全37/碰撞1/未知拒10，
  第180题1.08–1.10s漏检段以5次查询判碰撞；未知只拒不放
- 修 seg_seg_dist 第二条退化成点不投影（模型内退化胶囊686受影响）；但7586个加密点的组最小间隙
  逐位不变、2000样本JS对拍仍 PASS → 不解释轮次30漏检、不改既有成绩
- 负结论：B=1 单段认证 P50 22.93/P90 58.43/P99 101.57 ms，432次中225次>20ms；
  自适应宽相位 cap 交错复测耗时无收益，先前1.6×为GPU顺序漂移，已在日志撤回
- 成本模型 L=ceil(log2(bound/(ga+gb)))、查询=2^L+1 与实测对齐（安全段2–17次，未知段33–65次）
- 新增8项段认证测试+1项回放测试（14→23项通过）；变异实测证明张量 max_depth 回绕会误放行
