Planar normalization validation API

For normalized topology, warning-only LOW_VERTEX_INCIDENCE and BAD_POLYGON_COUNT findings can leave their descriptive subchecks false while overall ok remains true. Strict normalized validation raises only for an error-severity finding.

Strict validation utilities for planar normalization outputs.

NormalizationError

Bases: ValueError

Raised when strict planar normalization validation fails.

validate_normalized_topology(normalized, domain, *, level='basic', check_vertex_edge_shift=True, check_edge_vertex_sets=True, check_incidence=True, check_polygon=True, max_examples=10)

Validate periodic shift and topology consistency after normalization.
