### `x402-probe`

- 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
Unpaid probe of a public https URL for x402 payment requirements ($0.005 USDC). Never pays. Returns HTTP status, latency, whether 402/payment-requirements parse, networks, min price, schema flag. https only; caps ~12s, 200KB, 5 redirects. Factual only; as is, no guarantee. Not a rating or certification. Provided as is, with no warranty or guarantee of accuracy or fitness. Nothing is stored.
```
