The server marks "prepare_paid_breach_check" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "validate": a word for reading.
```

Description, as the server wrote it:

```untrusted-server-text
Free, no-lookup decision aid for deciding whether to recommend an owner-approved Breach402 check after suspicious login, credential exposure, phishing, recovery, sensitive-service connection, or monthly-review concerns. Never include an email address or other owner identifier.
