- Device: multiDrawIndirect, drawIndirectFirstInstance and drawIndirectCount where present. - Buffers carry storage and indirect usage; a GPU-owned buffer is never swapped under a draw. - Compute programs from shaders/compute.list (binding 0 parameters, 1.. storage buffers), built by `ludic-dev shaders`; gpu_compute / gpu_dispatch / gpu_draw_mesh_indirect in gpu.ludic. - R3D_VK_PROBE=1: a dispatch read back (OK on the RTX 3070 Ti). - scatter_cull.comp: a tree layer's frustum test and LOD split on the GPU, with the lit, prepass, impostor and shadow-LOD draws reading its records. Behind R3D_GPU_CULL=1 and off by default: at the camp it is slower (43.0 fps against 53.3), because the frame's cost is per-draw descriptor sets and it adds empty-level draws. Validation-clean; OpenGL frames unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
