The 5-minute disk probe now reclaims storage automatically: from 85% it runs the gentle age-windowed Docker prune, from 90% it drops the age windows (docker-prune.sh --force: all unused build cache and unreferenced images, all stopped containers) so a mount can never silently max out. Alerts still fire at 85/90/95% and their hint now points at non-Docker growth when reclaiming is not enough. Force mode is reserved for the worker; deploys keep the gentle mode. Volumes are off-limits in every path.
Add scripts/docker-prune.sh (build cache >72h capped at 4g, unreferenced images >7d, stopped containers >24h; never volumes), run it after every CI deploy and compose update, and schedule a nightly prune from the host-side jobs-worker. Tighten the deployment contract tests to assert the scoped-prune boundaries.
