Chunk 19.0

After committing the status API changes, the assistant shifted focus to integrating live monitoring into the vast-manager HTML UI. The manager codebase was analyzed, revealing a single-file Go service (`main.go`) serving a dashboard (`ui.html`) with instance expansion for logs. A new `GET /api/cuzk-status/{uuid}` endpoint was added, which uses SSH ControlMaster to efficiently poll the cuzk daemon's HTTP status endpoint on port 9821, returning the JSON snapshot without exposing ports directly. The UI was extended with a comprehensive live visualization panel that appears when a running instance is expanded. It features a memory usage gauge, a per-job partition pipeline grid with color-coded phases (synthesizing, waiting for GPU, on GPU, done, failed), GPU worker state cards, SRS/PCE allocation tables, and aggregate counters. The panel polls every 1.5 seconds and automatically stops when the instance is collapsed, using an `AbortController` to manage the polling lifecycle cleanly. The themes of this chunk are finalizing the status API as a committed, production-ready feature, and building a real-time monitoring bridge between the cuzk proving daemon and the operator's management interface. The implementation prioritizes minimal dependencies (raw TCP HTTP server, SSH ControlMaster for connection reuse) and a clean, informative visualization that helps operators debug proof pipeline performance at a glance.
