Light1YT 57214f7c49 fix(tradein): backfill kn price_per_m2 (#573) ... 756 977 NULL-status rows in domrf_kn_flats imported from historical DOM.RF snapshots carry total_area but no price_rub, so the scraper's price_rub/total_area derivation never fires for them. This left 5/8 EKB districts at 0% price_per_m2 coverage and blocked the Limit_District_Median_Partial analytics limitation. Migration 100 adds a three-pass idempotent backfill: 1. price_rub / total_area (sanity net; 0 rows in practice) 2. domrf_kn_sale_graph.price_avg (type='apartments', latest snapshot) via obj_id join — fills 453 606 rows 3. peer median from free/sold/booked flats in the same obj_id — fills 620 more rows After backfill: 61.5% overall coverage (up from 3.7%), all 8 EKB districts get a non-NULL median (7/8 districts reach ≥ 60%). Also tightens the UPSERT: price_per_m2 now uses COALESCE so re-scraping NULL-status flats no longer overwrites a previously backfilled value.		2026-05-28 18:31:50 +05:00
