Empty is the ordinary answer. Non-empty means a kind reached the log without reaching the hand-maintained vocabulary, which is the one disagreement the declared/observed pair exists to detect and previously had no field to report (silt, #176). Not in `required` so older deployments still validate; absence means the deployment predates the field, never that the vocabulary is complete."
