Add a pure df parser (disk-usage.ts) with 85/90/95% threshold classification, a diskPressure() alert (Discord/email/alert_logs, severity escalates with fill), and a 5-minute host-side probe in jobs-worker.ts that raises one alert per crossing mount, cooldown-gated per mount+level. Real mounts only: overlay/tmpfs pseudo filesystems are ignored.
