nav_crowd_add_fixed adds a walker with no steering, and nav_crowd_place puts it (snapped to the mesh) where the player is, with the velocity they have, each frame. The others plan round it by that velocity, and whatever it was pushed by is undone at the next placement. crowd_test: six walkers aimed through a standing player come no closer than 1.71 m and all get past, and the player stays where it was put. nav 16/16 on the Mac and the PC; DLL KERNEL32 only.

nav_crowd_add takes how hard a walker keeps its distance, and WildSpecies.spacing (default 2) is a species' room from others walking by, which the valley hands the crowd. Both libraries are rebuilt; nav 15/15 on the Mac and the PC, DLL KERNEL32 only. wildlife 26/26.

The shim builds DetourCrowd from the same pinned Recast & Detour tag. nav_crowd_start puts a crowd on a kind's mesh, with the mesh's tastes as its filters. Walkers are added (snapped to the mesh), sent and sped through verbs, stepped together, and read back into nav_agent_*. nav_crowd_us times the stepping with the OS clock. Dropping a mesh drops its crowd first. On the test meadow, twenty walkers crossing head-on never come closer than their two radii (0.7003 m), all arrive, and a step costs about 12 us. nav 15/15 on the Mac and the PC; the DLL still imports KERNEL32 alone.

nav_us() gives the microseconds spent in nav_path across the loaded meshes. The shim times each path with the OS's monotonic clock (clock_gettime, or QueryPerformanceCounter from KERNEL32), so the DLL still needs no C++ runtime. Both libraries are rebuilt, and 13 tests pass on the Mac and the PC.
