Adapter setting vk_shader_dump=1: every distinct module once to files/fp_vk_shaders/<size>_<sha256>.spv, each vkCreateShaderModule as one index.txt line (order, time), to find the shader behind a GPU hang for a vk_shader_fix. Agent v72 collect_diag returns the newest dumped modules (Vulkan and OpenGL ES dumps); diagnostics bundle them. Triage gpu-hang suggests the dump for the session's graphics API (FrameBridge's swapchain formats).
