NSED v0.5.1 ships the human-in-the-loop control plane we've been building toward: operators can pause agents mid-deliberation, review and edit buffered responses before they're committed downstream, patch live config without restart, and auto-flag underperformers by score divergence.

The operator UI ships as zero-dependency vanilla JS — no npm graph, nothing a compromised package registry can inject into a control plane that has authority over live agent responses.

For regulated deployments: EU AI Act Art. 14, MAS AIRM, and FINRA 2026 all require demonstrable human oversight. This is the architecture that satisfies it — and you can audit the implementation directly from the source repo.
