实验 66:A60 Hierarchical Guard + MV Recall

层级门控审计:MV consistency 不能做 hard gate,但可作为 soft diagnostic

实验定位 层级门控负结果 / 诊断正向

A60 接在 A59 后面,不再让 A58 直接替代 A53,而是测试更合理的层级方案:A53 saturation guard 先负责 Chamfer 保真,A58 multi-view consistency 只作为外围 veto 或 recall 信号。

结果显示:A53 仍是最优 no-GT 主路线。MV veto 会错杀 gso002 的好编辑,使 mean ΔChamfer 从 A53 的 -0.0002597 退化到 -0.0000965;guarded MV recall 也没有超过 A53,ΔChamfer=-0.0001586、ΔF@5=0.000922。

Hierarchical Rules

  • a60_a53_mv_veto:A53 选非 carrier 时,如果 MV depth error 比 carrier 差,则回退 carrier。
  • a60_guarded_mv_recall:A53 允许编辑时,只有 A58 的 MV error 明显更好才切换;A53 选 carrier 时 hard guard 阻止 recall。
  • a60_oracle_a53_vs_a58:只用于回顾验证,比较 A53 与 A58 谁的 GT Chamfer 更低。

False Reject

gso002 是决定性反例:A53 的 depth_signed_strong 让 GT Chamfer Δ=-0.001632、F@5 Δ=+0.009673,但 MV depth error 相对 carrier 变差。因此把 MV consistency 当 hard veto 会拒绝真实好编辑。
