Duplicated region IDs

data_quality

The same admin id mapping to multiple polygons (data error) breaks partition assumptions.

Detection

id appears on > 1 disjoint feature unexpectedly.

Mitigation

Dedupe / union by id
Fail loudly on unexpected duplicates

Affected conversions

Admin polygons → H3 (max-overlap partition) approximate
Admin polygons → H3 (weighted crosswalk) weighted
