Chunk 4.1
In this chunk, the assistant executed a definitive end-to-end validation of the Phase 0 gRPC pipeline for the `cuzk` daemon. After cleaning up stale processes, a fresh daemon was started and the `cuzk-bench` tool successfully submitted a 51 MB PoRep C1 proof request. The daemon correctly processed the input through the entire stack—deserializing the C1 wrapper, dispatching via the priority scheduler, and invoking the real `seal_commit_phase2` function. Although the proof failed as expected due to missing 32 GiB Groth16 parameters, the error was cleanly propagated back to the client, and the daemon's Prometheus metrics accurately recorded the failure (`proofs failed: 1`). This confirmed that the core request/response cycle, error handling, and monitoring infrastructure are fully operational. The focus then shifted to resolving the parameter dependency to achieve a fully successful proof. The user ran `curio fetch-params 32GiB`, but a path resolution bug in the tool caused the files to be downloaded to the current working directory (`~/scrot/`) instead of the intended absolute path (`/data/zk/params/`). The assistant diagnosed the issue, located the downloaded files (including the critical 45 GiB `stacked-proof-of-replication` parameter file), and copied them to the correct directory, preparing the environment for a real proof run. The overarching theme of this chunk is the transition from validating the software architecture to resolving real-world environmental dependencies. The successful end-to-end test proved the robustness of the Phase 0 scaffold, while the parameter troubleshooting highlighted the practical challenges of integrating with external tooling (`curio fetch-params`) and managing large files across different paths. The session effectively closed the loop on the core communication path, setting the stage for the first fully successful proof execution in the next step.
