## Known failure modes

- Empty or missing 'text' field returns an error or undefined behavior
- Extremely long text inputs may hit processing limits
- Malformed JSON body may result in a 400-level error
- Service may return generic 'processed'/'success' without detailed count breakdown due to minimal response schema
