Segment 12
In this sub-session, the assistant deployed the self-check fix to the production cuzk worker, ensuring that invalid partition proofs are rejected at source rather than silently returned. After connecting to the remote machine and confirming the Phase 7 pipeline path, the assistant audited the codebase and discovered the same diagnostic-only self-check bug in two additional assembly paths—the batched multi-sector path and the single-sector pipeline path—and fixed those as well. To avoid a slow Docker rebuild, the assistant built a minimal cuzk binary locally using a CUDA 13 devel environment, extracted the 27MB binary, uploaded it via SCP, and hot-swapped the production daemon with minimal downtime. The new daemon started cleanly, loaded its SRS parameters, and now enforces the self-check across all four pipeline modes (Phase 6, Phase 7, batched, single-sector), preventing the intermittent 'porep failed to validate' errors from propagating to the ProofShare challenge protocol.
