* empty) account data; probe routes drive identifier-addressed operations
* against nonexistent identifiers and must surface the service's typed
* not-found tag — an IAM gap would surface AccessDeniedException and fail
* the route with an opaque 500.
*
* The cluster/instance-scoped bindings (`CreateDBClusterSnapshot`,
* `CreateDBSnapshot`, `FailoverDBCluster`, `Start/StopDBCluster`,
* `Start/Stop/RebootDBInstance`) resolve a bound resource at deploy time,
* so they need a live database (~10 min, billed hourly) and are exercised
* only under RDS_TEST_LIFECYCLE-gated runs.
