feat: depth buffer + 3D model matrix — rotating cube now looks correct
- Depth image (D32_SFLOAT) + image view created in VulkanSwapchain
- VkPipelineDepthStencilStateCreateInfo: depth test + write enabled, CompareOp=Less
- Push constant changed from float angle (4B) to mat4 model (64B)
- 3D rotation: RotateY * RotateX in renderer, applied via push constant
- Vertex shader: gl_Position = vp * model * vec4(pos, 1.0)
- Depth attachment in VkRenderingInfo + depth clear (1.0)
- Depth image layout transition (Undefined → DepthStencilAttachmentOptimal)
- New Vulkan functions: vkCreateImage, vkDestroyImage, vkGetImageMemoryRequirements, vkBindImageMemory
- New structs: VkPipelineDepthStencilStateCreateInfo, VkStencilOpState, VkImageCreateInfo
- New enums: VkCompareOp, VkImageType, VkImageTiling
- 0 validation errors

feat: rebuild Vulkan renderer from scratch — pure P/Invoke triangle (Vulkan 1.3)
- Complete rewrite of Engine.Graphics.Vulkan with pure P/Invoke (no wrapper libs)
- Vulkan 1.3: dynamic rendering (vkCmdBeginRendering/vkCmdEndRendering),
synchronization2 (vkQueueSubmit2, vkCmdPipelineBarrier2)
- Split types into VulkanHandles.cs, VulkanEnums.cs, VulkanStructs.cs
- Staging buffer → device-local vertex buffer pattern
- Correct swapchain semaphore indexing (per-image, not per-frame-in-flight)
- VK_EXT_debug_utils debug messenger with validation layer fallback
- Dynamic viewport/scissor (no pipeline recreation on resize)
- Simplified Program.cs to triangle-only rendering
- Removed old Silk.NET renderer, ImGui, PBR shaders, screenshot code
- Updated VULKAN_IMPLEMENTATION_PLAN.md with full architecture decisions

feat: pure Vulkan P/Invoke renderer — no wrappers, SDL3 window, SPIR-V shaders
- Engine.Graphics: restored interfaces (IRenderContext, IRenderer, RenderBackendFactory),
loaders (ObjLoader, GltfLoader), ProceduralMesh, MeshMath, SceneSerializer
- Engine.Graphics.Vulkan: pure P/Invoke to libvulkan.so.1/vulkan-1.dll
- VulkanNative: library loading, function pointer loading via vkGetInstanceProcAddr
- Vk: static function cache for ~80 Vulkan functions, all delegate types
- VulkanTypes: ~50 structs, ~20 enums matching Vulkan C headers
- VulkanContext: instance, physical device, logical device, surface, memory types
- VulkanSwapchain: swapchain, image views, depth image, render pass, framebuffers
- VulkanPipeline: graphics pipeline, descriptor set layout, shader modules
- VulkanBuffer: vertex/index/uniform buffers, staging, memory allocation
- VulkanRenderer: command buffers, sync (semaphores/fences), render loop, 2 frames in flight
- GLSL 450 shaders: PBR lighting (Fresnel, ACES, gamma), directional+point lights
- Compiled to SPIR-V via @webgpu/glslang WASM
- CortexEngine.App: switched to vulkan backend, removed Raylib/OpenTK/ImGui refs
- Tests: all 66 pass (ObjLoader, MeshMath, ProceduralMesh, SceneSerializer, etc.)
- Camera tour: 16 poses, screenshots captured, clean shutdown

feat: modular HAL, Raylib backend, PBR shading, textures, 60 unit tests
- Replace hardcoded SDL3 windowing with IWindow/IInputState/Key abstractions
- Each render backend owns its window (Raylib GLFW, SDL3 for Vulkan)
- Raylib backend: DrawModelEx, custom GLSL shader with Fresnel, ACES
tonemapping, gamma correction, hemisphere ambient
- Fix backface culling, mesh memory (NativeMemory.Alloc), texture loading
- Camera controllers use backend-agnostic Key enum (inverted yaw/strafe)
- Demo scene: 8 cubes, 7 spheres, torus knot OBJ with checker texture
- Extract ProceduralMesh + MeshMath from Program.cs to Engine.Graphics
- Vulkan backend deferred (compiles, untested, IWindow-compatible)
- 60 unit tests: ObjLoader, camera controllers, AiCommandProcessor,
RenderBackendFactory, Timing, ProceduralMesh, MeshMath, Transform
- AGENTS.md for opencode integration
