Scope: dataset
Default severity: error
Certainty: deterministic
Cost: full scan
Reports vector geometries that fail the geometry engine's validity predicate. File-based checks require deep inspection when validity is not available from metadata.
PASS: the scanned dataset contains no invalid geometries.
FAIL: one or more invalid geometries are present.
UNKNOWN: geometry validity has not been scanned.
NOT_APPLICABLE: the subject is not vector data.
Automatic geometry repair is intentionally not performed because repair can change geometry type and topology.
