   primitive geometry、static filtering、minimum distance、attachment
   transformation、site attachment 与 normal；grid/pinhole ray 几何、yaw/world alignment、hit-point packing 与 geometry synchronization 由 focused fake-caster test 覆盖；mesh/hfield 数值 parity 由 UniSim 与 `uni_ray` contract suite 负责。
+- A direct-engine G1 physics-throughput benchmark now covers Genesis

+  stepping only and does not add a training-runtime or backend-support claim

+### Fixed / 修复
+
+- The CUDA inference IPC ring now uses event synchronization instead of IPC-event
+  stream waits on HIP/ROCm. This avoids the ROCm CLR 7.2 emulated-event modulo
+  defect that produced `hipErrorInvalidValue` when the 33rd signal-slot event
+  was reused, allowing production-shape ROCm Genesis SAC runs to complete. The
+  compatibility path is performance-impacting; NVIDIA CUDA continues to use
+  stream waits
+  ([#2530](https://github.com/Motphys/UniLab/issues/2530)).
+  CUDA inference IPC ring 在 HIP/ROCm 上现在使用 event synchronize，而不是
+  IPC-event stream wait。这避开了 ROCm CLR 7.2 emulated-event 的 modulo 缺陷；
+  该缺陷在第 33 个 signal-slot event 复用时触发 `hipErrorInvalidValue`，修复后
+  production-shape ROCm Genesis SAC run 可以正常完成。兼容路径会影响性能；
+  NVIDIA CUDA 继续使用 stream wait
+  （[#2530](https://github.com/Motphys/UniLab/issues/2530)）。
