/**
 * True iff a resource has been hard-deleted - a base read returns HTTP 410 Gone.
 *
 * The `_history` LIST viewers use this to tell a "resource was deleted" state apart from a transient
 * failure. On our HealthLake datastore the `_history` LIST endpoint returns an opaque 500 for a
 * hard-deleted resource, so the LIST error alone can't distinguish "deleted" from
 * "temporary server error" - a base read returning 410 Gone is the reliable signal. Any other
 * outcome (resource still live, or a different/transient error) returns false.
 *
 * `get` throws the app's `HttpError`, which carries `.status`. We read `.status` structurally rather
 * than importing HttpService so this guard stays dependency-free (and unit-testable without pulling
 * in the services barrel).
