Segment 4
In this sub-session, the assistant executed the Phase 0 implementation of the cuzk pipelined SNARK proving engine from scratch. The entire extern/cuzk/ Rust workspace was created with six crates, the full gRPC protobuf API was defined, and the core engine architecture with a priority scheduler was implemented. Build system issues such as Rust edition incompatibilities and missing dependencies were resolved, and gRPC message size limits were increased to handle large inputs. A successful end-to-end validation of the gRPC pipeline was achieved, including daemon startup, client query, proof submission, and error propagation. Finally, parameter dependencies were resolved by fetching 32 GiB Groth16 parameters and copying them to the correct directory, preparing for a fully successful proof execution.
