- GpuDrivenCaps: probe + enable Vulkan 1.2 core features (drawIndirectCount, descriptor indexing, non-uniform indexing, update-after-bind) at device creation; the toolchain's Vulkan headers omit the core drawIndirect bit so it is assumed supported and left untouched. - Bindless Set1: sampler2D array (4096) + samplerCube array (64) + SSBO table array (64) with PARTIALLY_BOUND | UPDATE_AFTER_BIND; textures register on creation, placeholder-filled with the 1x1 white texture/cubemap. - GPU tables: GpuMeshRecord (bounds + index/vertex ranges) filled at mesh upload and GpuMaterialRecord built from Material params, uploaded to host-visible SSBOs with fixed capacity. - FrameArena: per-frame-slot host-visible ring allocator, reset each begin3DFrame; unused until phase 1 (indirect draw). - Tests: GpuDriven.capsAvailable / bindlessTextureRegistration / meshTableRegistration (GPU runtime verification pending driver recovery). Rendering is unchanged: nothing consumes the new infrastructure yet.
