**Active-path evidence (Builder ran the exact prune command; gate reaches it only ≥80% disk):** `docker image prune -f --filter until=24h` reclaimed **2.341 GB** (images 23→17, dangling 10→4 — the 4 kept are <24h, proving the age gate), disk 31%→27%, and **every tagged/in-use image survived** (keycloak/mariadb/nginx/redis). Disk bounded without `-af`.
**EXPECTED:** old timer not-found; `ci-docker-prune.timer` enabled+active (daily); manual run below
80% prints the no-op line and removes nothing; module flags are `--filter until=24h` only (never
`--all`/`--volumes`); swarm.nix has no live autoPrune.
