`keepFloor`: monitor starts replacements when **available** (running, healthy, not paused) drops below `min`. That is how tree nodes stay at three live copies if one is paused, crashed, or not responding.

Hosts: [`machines.json`](machines.json). Add machines in the monitor UI or POST `/api/machines`. Placement is least-loaded eligible host. Remote: `node src/agent.js`.
