   - q: "Why does a provider show no data?"
     a: "Three reasons. The provider's key is not configured on the harness, so it is skipped. The provider does not list the headline cell. Or the provider answered without a usable quote, in which case its success rate drops and the cell is purged rather than left at a stale value."
