Lightweight stdlib-only Python agent runs on each monitored host, collects CPU / memory / disk / load / uptime from /proc every 30s, and POSTs signed payloads to the Roundtable ingest endpoint. One-line curl-pipe installer creates a hardened systemd unit; admin UI manages host registrations with rotate / revoke. - agent.py: 370 LoC single-file daemon, ring buffer + exponential backoff - ingest route: bearer-token auth, metric expansion into plugin_metrics - install.sh.j2: systemd unit with NoNewPrivileges / ProtectSystem / ProtectHome - settings UI: add host / rotate token / delete registration (admin-only) - dashboard widgets: fleet-glance table + per-host history chart - stale-agent scheduler: 60s log warning for agents past 180s silence Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
