+"""Yandex offer price-history capture из gate-ответа.
+
+В отличие от Cian (отдельный detail-fetch priceChanges, см. cian_price_history.py),
+Yandex gate-ответ уже несёт `price.previous` + `price.trend`, которые парсятся в
+`ScrapedLot.price_previous_rub` / `price_trend`. Otsenka-скрапер НЕ нужен — gate достаточно.
+
+Эта функция вызывается из scrape_pipeline СРАЗУ ПОСЛЕ save_listings(те же lots): резолвит
+listing_id по (source='yandex', source_id), читает последнюю по change_time точку
+offer_price_history и идемпотентно дописывает наблюдение, если цена изменилась.
+
+Idempotent-логика (на каждый yandex-lot):
+  - история ПУСТА:
+      * price_previous задан И != price_rub → seed previous-точку (change_time = now-1d,
+        timestamp синтетический — gate реального времени смены не несёт), затем current-точку;
+      * иначе → только current-точку (now).
+  - история ЕСТЬ и latest_price != price_rub → одна current-точка (now) — зафиксировали смену.
+  - история ЕСТЬ и latest_price == price_rub → skip (цена не менялась).
+
+Per-lot SAVEPOINT: один битый lot не валит весь батч. db.commit() в конце.
+psycopg v3 discipline: только CAST(:x AS type), никаких :x::type. Все timestamp'ы
+считаются в Python и биндятся как параметры (DB-agnostic, без Postgres-only interval).
