 *      application-default login` produces this).
 *   2. `external_account` credentials file (Workload Identity Federation).
 *   3. `service_account` credentials file (raw GSA key - rarely used in
 *      OpenClaw, included for completeness).
 * Metadata-server ADC is intentionally not detected here: `google-auth-library`
 * probes the default metadata hosts asynchronously at request time, and the
 * provider wires the Vertex transport without this sync predicate.

 * production cases on GKE: Workload Identity, Workload Identity Federation,
 * service-account JSON keys), we hand off to `google-auth-library` which

 * symbol rename across the existing patch surface; the docstring above is
 * the truth, the name is legacy.
