## Dev Board Ticket https://dev.azure.com/TDEI-UW/TDEI/_workitems/edit/3477 https://dev.azure.com/TDEI-UW/TDEI/_workitems/edit/3022 ## Changes **PR Title** Fix OSM→OSW handling for ext-only geometries and node reference export **PR Summary** This PR fixes several OSM→OSW regressions around `ext:*` tags and export classification. - Semantic feature recognition now uses canonical OSM tags only; `ext:*` tags are preserved as extensions instead of being treated as feature-defining tags. - Closed ext-only ways such as `ext:demolished:building=yes` now export correctly as polygons and no longer fall through to point geometry construction, which previously caused `KeyError: 'lon'`. - GeoJSON export now keeps topology endpoint points in `nodes.geojson`, ensuring edge `_u_id` and `_v_id` references remain OSW-compliant during roundtrip validation. - Added regression coverage for `bug_3477`, serializer-level node/point remapping, and the OSW compliance failure. - Bumped the package version to `0.3.3` and updated the changelog. ## Testing - Updated existing unit test cases - Added 2 new unit test cases
