5e83a6e63a* MVUM Layer 0: spatial index foundation Additive only — no routing logic, no response-format, no Valhalla changes. - mvum.py: add MVUMSpatialIndex. Loads mvum_roads + mvum_trails from navi.db (read-only), decodes the pure-WKB shape blobs with shapely, builds a shapely.strtree.STRtree, and keeps a parallel list of full feature records (all columns minus the blob, plus the parsed geometry) with a by_id lookup. Exposes query_bbox(min_lat,min_lon,max_lat,max_lon) and query_buffered_line(coords, tolerance_m) returning candidate records (coarse bbox + buffer; full parallelism filter is a TODO for PR-B). Reports road_count, trail_count, bbox, build_time_seconds, memory_estimate_mb (RSS delta). - app.py: build the index once per process (singleton) at service init; stored on app.config[MVUM_SPATIAL_INDEX]. Failure is logged and degrades to None. - admin.py: GET /api/admin/mvum-spatial/info (Authentik-gated, read-only) returning the counts/bbox/build-time/memory stats. - tests/test_mvum_spatial.py: index loads, query_bbox returns Boise-area features, query_buffered_line returns a feature, admin endpoint returns counts. Diagnostic before coding (read-only): roads_with_shape=150568/null=68, trails_with_shape=21995/null=6746 (green), shape blobs are pure WKB MultiLineString. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Fix lat-aware buffer + count WKB parse failures - query_buffered_line: replace the static _DEG_PER_M with _buffer_degrees_for_meters(), which scales longitude degrees by cos(lat) and uses the larger lat/lon equivalent; buffer at the polyline avg latitude. Early-return [] for empty coords. - _load_table: count WKB parse failures and logger.warning once per table when > 0.
