DeepSeek's Harness team published a design argument and an MIT-licensed prototype on October 31, 2026: one always-on router that dispatches work into parallel isolated workers and only interrupts you when a decision is actually needed. The prototype is research code scoped to a single GitHub repo, so this is not an install guide — it is a read on the router-and-workers topology and the permission policy that makes silence a first-class outcome.
