bot-backend	ec82742456	feat(tradein): same-building anchor safe-guard (#755) ... CLIENT-VISIBLE pricing (killer-factor, demo 2026-06-01). The same-building anchor replaced headline median/range/confidence with an over-confident premium on as few as 2 same-building asking comps. Human-chosen (Anton) 3-part safe-guard, all implemented: 1. min_comps 2 -> 4: anchor fires only with >=4 same-building comps. 2. confidence cap: at <5 anchor comps, confidence cannot be 'high' -> medium. 3. MAD-clip: drop price_per_m2 outliers among anchor comps before aggregation (k=estimate_sb_mad_k=3.5); if <min_comps survive, anchor does NOT fire (fallback to radius-median). Guards against price typos inflating anchor. Anchor still REPLACES the headline (uplift-no-replace variant NOT chosen). quarter-index/radius-tier/asking-sold untouched. 8 new unit tests; 61 anchor tests pass, ruff clean. MERGE-GATE (client-visible, like #764/#858): do NOT merge without a green backtest #763 (held-out MAPE <= 18.7% + canonical A/B Малышева 125 / Заводская 44а). Backtest needs live DB — pre-merge human/qa step. Refs #755, #694	2026-05-31 12:19:50 +03:00
