…xtensions ## DevBoard - https://dev.azure.com/TDEI-UW/TDEI/_workitems/edit/4066 ## Changes - Added shared geometry cleanup helpers for LineString, Polygon, MultiLineString, and MultiPolygon geometries. - Removes duplicate consecutive coordinates from line and polygon geometries. - Prevents zero-length LineString geometries from being emitted as OSW edges or lines. - Prevents collapsed or zero-area Polygon geometries from being emitted as OSW polygons or zones. - OSM edge segments with identical endpoint coordinates are no longer emitted as OSW edges, even when node IDs differ. - Collapsed OSM edge/way features are preserved as valid custom OSW points when a coordinate is available. - Fallback custom OSW points preserve original way tags as `ext:*`. - Prevents invalid OSW node output containing edge properties like `highway`, `footway`, or `surface`. - OSW→OSM collapsed edges, lines, polygons, and zones are converted to OSM node/Point fallbacks instead of being silently dropped. - OSW→OSM duplicate consecutive coordinates are cleaned before conversion. - OSM→OSW unknown, unsupported, or non-OSW-compliant tags are preserved as `ext:*`. - Invalid values for known OSW fields are preserved as `ext:*` instead of being dropped. - Existing `ext:*` tags remain unchanged. - Added real-format OSM XML fixtures for zero-length OSM scenarios. - Added zipped OSW datasets for zero-length OSW scenarios. - Added consolidated zero-length geometry unit coverage. - Updated OSW normalizer tests for `ext:*` preservation behavior. ## Validation ```text 288 tests passed ```

_u_idand_v_idendpoints must exactly match referenced node coordinates.Zone
_w_idvertices must exactly match referenced node coordinates.Detects coordinates with more than seven decimal places.
Reports a non-blocking message through

is_valid.Rejects edges, lines, polygons, and zones containing more than 2,000 vertices.
Exactly 2,000 vertices remain valid.
Supports polygon interior rings, multi-geometries, and external extensions.
