No UPS. Power loss stops ~60 containers dirty — postgres x6, sqlite WAL files, btrfs — and the 2026-08-10 outage already produced one real incident (Authelia SMTP crash-loop on boot). A dirty stop is also the main window for the bind-mount config/stale-secret mismatch class.

Standard shape: consumer UPS with USB data port + NUT on the host — graceful just down + shutdown on low battery, and a NUT Prometheus exporter so battery/load ride the existing alert path.

Hardware purchase, so the sizing/model decision is the blocking step; the software side is small.

A dirty stop is also the main window for the bind-mount config/stale-secret mismatch class.
