| crbro_inspect | Read-only views by id or name: view=status (with the version the process runs, and the one installed on disk when npx replaced it under a running process)… |
| crbro_learn | Store a fact, decision, pattern, preference, error or debt — with the keywords a future question may use. supersedes retires the old version in the same… |
