### `invoice_duplicate_recovery`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Computes exact overpayments across caller-supplied approved invoices, payments, and recorded credits, and produces an evidence bundle for requesting vendor credit review. Never sends requests, never asserts legal refund entitlement, and never takes automatic financial action. Price: 0.05 USDC per completed bounded job on Base.
```
