6/// - Driver capability flags are inconsistent (e.g., native_varchar=true but varchar type not specified)
7/// - Required capability fields are missing or contradictory
8///
9/// These errors indicate a programming error in the driver implementation itself,
10/// not a user error or runtime condition.
