Expand description

Observes completed engine requests. Implemented by higher layers (e.g. the REST API’s Prometheus metrics); the default is a no-op so libraries and CLI tools never pay for telemetry they don’t serve.

status is one of ok, empty or error. scope/kind describe the failure reason and are None on success.
