+> Phase 3 PyTorch Profiler 首轮 smoke 已证明双节点 16 个 rank 均可完成 trace 写盘，Head/Worker 分别生成 8 份、约 1.5/1.4 GB 压缩 trace。修复当前 OpenSSH 不接受 `scp remote:/path/.` 导致 Worker 结果未回收的问题，改为 SSH tar 流式传输；正式入口不再忽略回收失败，并新增至少 16 份 PyTorch rank trace、至少 2 份 Nsight 节点报告的结果门禁。

 > 为 Phase 2 实验档案第 11 节的 GPU/DCGM、CPU/进程/NUMA、双 Rail RDMA、PCIe/NCCL 四组结果补充服务器证据路径。每组同时标明结构化汇总 CSV、Head/Worker 原始采样日志、通信原始输出及实际命令文件，便于从结论直接追溯最终 Run `dsv4pro-phase2-20260731-163620` 的证据。
