Дочинить Phase 1: #901 завёл browser-режим только в
AvitoScraper.__aenter__/_fetch_serp_html, но продакшн-пайплайн его обходит —run_avito_pipeline(scrape_pipeline.py:167) делаетscraper = AvitoScraper(); scraper._cffi = session(инжектит curl-сессию, не зовёт__aenter__), поэтомуself._browserвсегдаNoneи SERP/detail/houses/imv идут через curl, игнорируяscraper_fetch_mode.Доказано на проде (2026-05-31): city-sweep run_31 (
scraper_fetch_mode=browserуже выставлен вbackend/.env.runtime, контейнер пересоздан) сделал 480 lots за 78с с нулём/fetch-хитов в tradein-browser → шёл на curl. Ручнойasync with AvitoScraper()в browser-режиме при этом отдаёт реальную выдачу (53/53 price+area, firewall=0). Т.е. scraper умеет browser, а пайплайн — нет.План (стадии, по PR)
Stage 1 — пайплайн SERP+detail+houses на BrowserFetcher (HTML, без правок browser-сервиса)
scrape_pipeline.py:run_avito_pipeline: новый параметрshared_browser: BrowserFetcher | None = None.browser_mode = settings.scraper_fetch_mode == "browser". В browser-режиме:scraper = AvitoScraper(); scraper._browser = (shared_browser or own BrowserFetcher); SERP идёт через уже-существующую browser-ветку_fetch_serp_html. Curl-путь без изменений.run_avito_city_sweep: в browser-режиме поднять ОДИНasync with BrowserFetcher() as bfи прокинутьshared_browser=bfво все anchor'ы (параллельно текущему sharedAsyncSession). Camoufox не поднимать per-anchor.avito_detail.py::fetch_detailиavito_houses.py::fetch_house_catalog: новый параметрbrowser_fetcher: BrowserFetcher | None = None. Если задан →html = await browser_fetcher.fetch(url)→ существующийparse_*; soft firewall-check (_is_firewall_page) →AvitoBlockedError(для consecutive_blocks-abort). Curl-ветка без изменений./fetch-хиты в tradein-browser на ВСЕ запросы (SERP+detail+houses), реальные данные, без ban.uv run pytest -k avito+ruffзелёные. Defaultscraper_fetch_modeне трогаем.Stage 2 — browser-сервис: capability JSON/POST (
/fetch-json)browser/**: новый эндпоинтPOST /fetch-json {url, method, headers, body}→ in-pagefetch()через camoufox (same-origin на avito.ru), вернуть JSON/текст. Билд нового browser-образа (build-browserв deploy-tradein.yml).BrowserFetcher.fetch_json(url, *, method, headers, body)→ httpx к/fetch-json.Stage 3 — IMV на browser
avito_imv.py/house_imv_backfill.py: маршрут IMV-вызовов (JWTgeoFieldsHash, suggest→evaluate/evaluation/realty) черезBrowserFetcher.fetch_json. Пайплайн прокидывает browser в IMV-фазу.Не делать

✅ Stage 1 merged — PR #916 (squash, sha
9fbe8e2) →status/qa.⚠️ Эпик НЕ закрыт — это 3-стадийный план, смерджена только Stage 1 (пайплайн SERP+detail+houses через BrowserFetcher). Остаются:
/fetch-json(POST/JSON capability)avito_imv.py/house_imv_backfill.py)QA: проверить только Stage-1 DoD после деплоя — city-sweep в browser-режиме даёт
/fetch-хиты вtradein-browserна SERP+detail+houses (НЕ IMV — она осознанно осталась на curl до Stage 3), реальные данные, без ban. На pass — НЕ закрывать #915, вернуть вstatus/ready scope/backendдля Stage 2 (а неstatus/done).Browser-mode включён на проде (
backend/.env.runtime) → деплой этого мерджа активирует реальную browser-маршрутизацию SERP.QA INCONCLUSIVE (06.06) — инфра ✅, свежего прогона нет:

NetworkError(500ms settle после навигации мало) → один retry лечит, но добавляет ~30с/дом. Тюнинг settle — отдельным тикетом.📊 At-scale validation (2026-06-26 15:38 UTC, IMV-окно): nudged

Recycle-концерн из deep-review НЕ материализовался. Throughput bound = анти-бан page-pacing avito (by design, безопасно), не баг. #562-разблокировка подтверждена в проде на потоке.
