"""Trade-In Estimator — реальное SQL aggregation поверх listings + deals.
|
||
|
||
Заменяет старый _mock_estimate() из api/v1/trade_in.py.
|
||
|
||
Алгоритм:
|
||
1. Geocode address → (lat, lon)
|
||
2. SELECT listings с фильтрами:
|
||
- PostGIS ST_DWithin (geom, point, 1000m) — радиус поиска
|
||
- source ≠ avito (у Avito фейковые anchor-jitter координаты — не гео-аналог)
|
||
- rooms = target_rooms (точное совпадение)
|
||
- area_m2 BETWEEN target × 0.85 AND target × 1.15
|
||
- scraped_at > NOW() - 14 days (свежие)
|
||
- is_active = true
|
||
3. Tukey outlier filter (1.5 × IQR rule)
|
||
4. Median / Q1 / Q3 / count → confidence
|
||
5. То же для deals (period = 12 mo).
|
||
6. Сохранить в trade_in_estimates + вернуть AggregatedEstimate
