## Findings

- **warn** Annotations that disagree with the tool in `calculate_old_age_single_payment` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_old_age_single_payment" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "calculate_old_age_single_payment" says "payment": a word that usually means money moves, which cannot be taken back.
```
