Segment 20
This sub-session focused on finalizing the vast-manager cuzk status monitoring integration. The Go backend and HTML UI were deployed to the manager host, SSH keys were configured to enable tunneled polling, and the full chain from browser to cuzk daemon was verified with live proof data. Two bugs were fixed: a race condition in partition_gpu_end that caused GPU workers to always show as idle, and truncation of job IDs to 8 characters. The synth_max display was changed from a static config parameter to a dynamic budget-based computation. Subsequently, the partition scheduling order was overhauled from random tokio::spawn ordering to a deterministic FIFO mpsc channel, ensuring partitions are processed in pipeline order. Deployment of the new binary revealed an overlay filesystem caching quirk that required using a path outside the container's lower layers.
