- UniformBuffer ring 支持 eStorageBuffer usage（GPUDriven 实例矩阵 per-frame-slot，正确性保证与 UBO 一致：fence 等待后写入） - DescriptorManager 加 UpdateStorageBuffer；池补 STORAGE_BUFFER 类型 - Set0 新增 binding1 = 实例矩阵 SSBO（vertex 读取，std430） - Forward pass 重写：每帧从 ECS 收集实例矩阵（按 mesh 聚合 batch， 两趟遍历保证 batch 区间连续），同 mesh 的 N 个实体合并为 一次 drawIndexed(instanceCount=N)，firstInstance 指向 batch 起点； vertex shader 经 gl_InstanceIndex 取模型矩阵，forward 不再用 push - draw 数 = 唯一 mesh 数，与实体数量解耦（4096 实例上限， 超出截断告警；聚合改哈希为后续 TODO） 验证：8 pass 全活，validation 0 error 0 warning，GPU Timings 面板 实测各 pass 毫秒，场景渲染与阴影正确
