Segment 34

In this sub-session, the team completed the upstreaming and build system readiness for the cuzk proving engine integration with Curio. They decided to vendor the forked Rust crates (bellpepper-core, supraseal-c2) directly inside the Curio repository to ensure a self-contained, reproducible build without upstream coordination. The Makefile was extended with make cuzk, install-cuzk, and uninstall-cuzk targets, including pre-flight checks for cargo and nvcc, while deliberately excluding the cuzk binary from default build targets to avoid affecting CI. All 37 untracked source files, including vendored crates, Go gRPC client wrapper, and modified Curio task files, were staged and committed with a comprehensive message. A new experimental-features documentation page (cuzk-proving-daemon.md) was added to the GitBook, and the build was verified with make cuzk completing in ~2 minutes and go vet passing on all modified Go packages.
