Segment 29

In this sub-session, the assistant completed the implementation and benchmarking of Phase 11's three memory-bandwidth interventions (serializing async_dealloc, reducing groth16_pool threads, adding global throttle flag), with Intervention 2 alone yielding a 3.4% throughput improvement. After analysis, the assistant designed a split API to offload b_g2_msm from the GPU worker's critical path, then implemented Phase 12 by restructuring the C++ CUDA code to allocate a persistent pending-proof handle, updating the Rust FFI boundary, and integrating the split API into the pipeline and engine worker loop, including spawning a separate tokio task for finalization.
