Give each in-flight framebuffer a complete post-processing chain and its own COMPUTE recording slot while retaining one physical queue. Claim framebuffer ownership before submitting compute work, and use the frame index for both COMPUTE and COPY recording state. Drain in-flight work before reconfiguring either chain so COPY never references replaced effect resources. Require both chains to contain the same effects, preserve pending damage, and release ownership on every pre-copy failure path.
