Segment 6
In this sub-session, the assistant systematically implemented Phase 1 of the cuzk proving engine, expanding it from a PoRep-only daemon to support all four Filecoin proof types. After thorough research into the filecoin-proofs-api signatures, Curio's Go FFI layer, and vanilla proof serialization formats, the assistant wired up real proving functions for WinningPoSt, WindowPoSt, and SnapDeals using correct FFI enum mappings and multi-proof formats. The protobuf definition was extended with repeated vanilla_proofs and renamed commitment fields, the engine was refactored to support a multi-GPU worker pool with automatic GPU detection and CUDA_VISIBLE_DEVICES isolation, and the bench tool gained full support for all proof types. The entire workspace compiled cleanly with 8 passing unit tests, and the milestone was committed as d8aa4f1d. After the commit, the assistant reviewed the project plan to assess remaining Phase 1 deliverables, deferred GPU affinity scheduling to Phase 2, and identified the gen-vanilla command as the next critical deliverable, completing research into vanilla proof generation function signatures.
