实验定位 10-case artifact expansion 正向
A49 回应 A48 的限制：A47/A48 只有两个 focus case，因为 A34/A35/A42 的可编辑 evidence 只生成到了 gso_002 和 gso_008。本轮先把 A34 的 persistent surface labels 扩展到 A31 的 10-case set，为后续 face/vertex mask、carrier 和 depth-sign router 的 10-case rerun 铺路。
结果：requested=10，completed=10，skipped=0；10/10 均生成 NPZ、PLY 和 patch JSON。平均 observed ratio=95.3%，surface conflict ratio=15.2%，patch count=41.7。

Data Flow
- 输入：A31 的 10 个 protocol4 GSO case。
- 路径：从 A23 rows 读取 baseline/repair mesh path。
- 信号：VGGT depth residual 投影到 repair surface samples。
- 输出：sample-level labels、patch clusters、PLY、PNG panels。
Why Artifact First
A47/A48 的 depth-sign router 需要 conflict mask 和 carrier。A49 不直接生成新 mesh，而是先把 surface evidence 扩展到 10-case，避免后续在缺 artifact 的情况下做伪扩展。

可视化结果
实验结论
- A49 成功补齐第一层 10-case artifact：10/10 case 都有 surface labels、patch clusters、PLY 和 PNG panels。
- case 分布很有信息量：gso_008 conflict ratio=0.7067，gso_006 conflict ratio=0.3031，说明它们是后续 depth-sign residual 的高价值对象。
- gso_005/gso_004 近乎全 neutral/low-conflict，后续 selector 应该更可能 defer 或保持 carrier，而不是强制 edit。
- 平均 observed ratio=95.3%，说明 10-case 上输入视角深度证据覆盖整体足够，但 gso_000/gso_006 的 observed ratio 较低，需要 confidence gate。
- A49 不是 mesh 质量提升实验；它是把 A47/A48 的小样本正结果扩展到 10-case 所必需的 artifact bridge。
下一步想法
- A50：基于 A49 labels 运行 A35-style face/vertex mask expansion，生成 10-case editable mesh masks。
- A51：扩展 A38/A41/A42 carrier 生成到 10-case，得到每个 case 的 topology carrier。
- A52：在 10-case 上重跑 A47/A48 depth-sign router，验证无 GT selector 是否仍优于 carrier 和 surface proxy。
- A53：把 observed/conflict/patch-count 作为 pre-router confidence，低 evidence case 自动 defer。
