- RenderGraph 声明 ShadowMap 虚拟资源（D32，2048²固定分辨率，独立于 swapchain 尺寸），Shadow pass 写深度 → Forward 声明 ShaderRead 采样， barrier/layout（DepthAttachment→ShaderReadOnly）全部由图自动预算 - Shadow pass：空 fragment shader + 深度偏移（斜率缩放）抗 shadow acne - Forward：UBO 增加 lightSpace 矩阵；Set 2 采样阴影图，手动对比 + 斜率缩放偏差；clamp-to-border 白色边界（光视锥外 = 全亮） - 光空间矩阵：主光方向反推 30 单位正交盒；深度重映射 [-1,1]→[0,1] - GetPhysicalView(slot)：物理镜像按帧槽位隔离，描述符 Compile 后一次性写入 - 修复 RG 隐蔽 bug：ShaderStage 与 PipelineStage2 位值不同 （eFragment=0x10 vs eFragmentShader=0x80），位值直转会撞出 TESSELLATION_CONTROL stage；改为逐位显式映射 - 修复 Camera 投影深度未重映射到 [0,1] 的潜在裁剪问题 validation 零错误零警告（3 passes / 5 barriers / 4 gpu images）
