+## Live queue dashboard (#429)
+
+`/queue` loads open PRs and issues for the default registry project (seed:
+**Gitea-Tools** on `https://gitea.prgs.cc`) using existing `gitea_auth` read
+credentials. The UI surfaces pagination proof (returned count, pages fetched,
+`has_more`, `inventory_complete`) and classification badges (`claimed`,
+`blocked`, `in-review`, `duplicate`) when evidence exists.
+
+If credentials are missing or the fetch fails, the page shows an explicit error
+instead of an empty queue (fail closed).
+
