Backend (parcels.py): - _parse_floors() helper для TEXT column (cad_buildings.floors хранится как строка, могут быть диапазоны "5-7"). Возвращает верхнюю границу. - _neighbors_summary(db, geom_wkt, our_cad) — query соседей в 100м (GIST): cad_num, building_name, floors, year_built, cost_value, area, address, distance. Aggregate: avg_floors_100m, max_floors_100m, median_cost_per_m2_100m, count_buildings_100m. Outliers cost/m² фильтруются (1k < x < 500k). - Overlap check: ST_Intersects + ST_Area(ST_Intersection) > 50 m² (transformed to UTM 32641 для метров). Если есть → has_existing_buildings: true + overlap_buildings list. - В response → neighbors_summary. Frontend: - Новый NeighborsBlock.tsx: hard red warn block для overlap (с building names + overlap_m2 + "Инвестиции невозможны без сноса"); summary metrics (avg/max floors, median price); toggle "Показать N ближайших" → таблица. - Border меняется на красный при has_existing_buildings — visual cue. - Добавлен в LandTab выше "Зонирование (ПЗЗ)". - TS типы: NeighborBuilding, OverlapBuilding, NeighborsSummary. Closes #46. Closes #21 (cad_buildings в Site Finder фильтрах).
