- `422`: limit is a valid integer but outside 1..50
- `429`: Rate limit exceeded
- `500`: The bounded operation failed without exposing internal exception details.
- `503`: The public read failed closed because its legal source catalog, subject classification, bounded projection, database helper or required artifact is unavailable. Clients must not infer an empty result.
