Same-building anchor set the headline median from anchor_sold_ppm2 (band-haircut
already applied), then forced expected_sold == headline. With the per-rooms
asking_to_sold_ratio also attached, the UI showed two identical numbers
('Ориентир запроса' == 'Ожидаемая цена продажи') + a mismatched -N% badge.
Fix: headline uses anchor_ppm2 (ASKING space); expected_sold = median × ratio
(single asking->sold mechanism) → distinct, strictly lower; null-guard preserved.
Median now asking-space (closer to golden asking reals; Хохрякова 48 4к 98.6M).
227 estimator tests pass; ruff clean.
