 **Not in this document.** Ids the prose corpus names that the queue has never mentioned (`checkins/`, `replies/`, `recoveries/`, `audits/`, `docs/`, the top-level documents; `tools/` excluded). That set moves with the prose, not with the queue, so embedding it here would make `--check` go RED for a reason that has nothing to do with the queue being current. It is reported on demand: `python3 tools/queue_index.py --outside`.
