Chunk 12.1
In this chunk, the assistant successfully deployed the critical self-check fix to the production cuzk worker. After connecting to the remote machine and confirming it was running the Phase 7 pipeline path, the assistant performed a thorough audit of the codebase and discovered that the same diagnostic-only self-check bug existed in two additional pipeline assembly paths—the batched multi-sector path and the single-sector pipeline path. These were promptly fixed to ensure all proof generation paths properly reject invalid proofs instead of silently returning them. To avoid the slow process of rebuilding the entire Docker image and restarting the container, the assistant devised a strategy to build only the cuzk binary locally using a minimal Dockerfile with the CUDA 13 devel environment. The resulting 27MB binary was extracted and uploaded to the remote machine via SCP. The production cuzk daemon was then hot-swapped: the old binary was backed up, the new binary was moved into place, and the process was killed and restarted with the same configuration arguments, ensuring minimal downtime. The central theme of this chunk is the systematic hardening of a critical production component against a class of bugs. The assistant not only fixed the reported issue but proactively identified and remediated the same vulnerability in all related code paths, ensuring comprehensive coverage. The deployment was successful; the new cuzk daemon started cleanly, loaded its SRS parameters, and is now serving requests with the self-check logic fully enforced across all four pipeline modes (Phase 6, Phase 7, batched, and single-sector). This prevents the intermittent "porep failed to validate" errors from propagating to the ProofShare challenge protocol by ensuring invalid proofs are caught and rejected at the source.
