auth_email_unavailable
No email provider, template set, or portal base URL is configured, so a verification or reset link cannot be minted or delivered. The account state is unchanged; nothing was half-issued.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
