The registry never reclaims blobs, so its store grows until the disk fills and the nightly builds fail with "no space left on device". Add registry-gc.sh, run weekly (Sunday 08:00), plus a daily dangling-image prune.
registry-gc.sh refuses to run while a build is active, stops the registry for a stable blob graph, deletes only untagged manifests (-m) and their blobs, restarts via an EXIT trap, and verifies a tag still pulls.
distribution 2.8.x GC does not follow OCI image indexes, so -m deletes their child manifests (distribution#3178). Default BuildKit provenance made every pushed tag an OCI index, which made -m destructive. Build scripts now pass --provenance=false (plain schema2), and registry-gc.sh refuses to run if any tag is still an index.
