dirBrowse rendered a single directory level but paid for a full recursive listing of the repo — on CephFS-backed LocalFS that is a walk of the entire storage root plus a sidecar read per object, which took Ceph down on large repos. Storage grows a ListDir primitive (os.ReadDir on localfs, Delimiter on S3) and the UI and the debian dists fallback use it; the recursive List stays for the docker page and now starts its walk at the requested prefix. The per-vrepo storage gauges on /metrics did the same full listing on every scrape; they are removed — the backend's own accounting (du, bucket metrics) covers capacity.
