Removed: unused Docker images + orphan volumes (incl. `zitadel_data` 801M), dormant `/opt` dirs (dendrite + its disabled `dendrite.service` unit, mastodon, dailysync, keycloak, media-repo, authelia, conduit, npm, manager, fusion, zitadel, rustdesk), rootless podman storage (6.4G stale goauthentik), home dev caches, apt cache, journal 3.8G→162M (+`SystemMaxUse=200M` drop-in, active next boot), truncated container logs (nghttpx 550M / traefik / squid). Follow-up: nghttpx-proxy logs grow ~25M/day (INFO per-connection); root-cause log-level/rotation fix still open (needs container restart approval).
 
-Remaining running services on this host: `soft-serve`, `vaultwarden` stack, `traefik`, `nghttpx-proxy` + `squid-backend` (undocumented forward proxy, `/opt/nghttpx`). `/home/windy/authelia` (76M) left in place — outside approved cleanup scope.
