avito_detail.parse_detail_html писал data-map-lat/lon прямо в listings
UPDATE COALESCE без bbox-валидации — в отличие от geocoder.py, который
фильтрует везде. Итог: 406 active avito-листингов с координатами
Питер/Тюмень/Уфа просочились в ЕКБ-датасет (ложные аналоги через Tier A
address-match оценщика). Prod-verified 2026-06-23.
- geocoder: DRY-хелпер is_within_ekb_bbox(lat, lon, bbox) + именованные
EKB_BBOX_TIGHT (geocoder-фильтр, числа не изменены) и EKB_BBOX_WIDE
(ingest-guard); 2 inline tight-проверки → хелпер (поведение identical).
- avito_detail: после извлечения lat/lon → reset None + logger.warning
если вне wide-bbox; листинг падает в geocode-cron путь (COALESCE NULL
не затирает прежнее хорошее значение).
- tests: bbox-хелпер (ЕКБ True, Питер/Тюмень/Уфа False, inclusive,
WIDE⊇TIGHT инвариант) + parse_detail_html guard end-to-end.
WIDE строго содержит TIGHT — guard физически не режет ничего, что
geocoder сам бы пропустил. NULL lat (14935, geocode backlog) — отдельная
проблема, не в scope. One-time cleanup существующих 406 — отдельно
(database-expert, prod data mutation).

Добавляет _is_price_sane() в cian_valuation.py: если sale_price_rub вне
[cian_valuation_min_rub, cian_valuation_max_rub] (дефолты 500k/500M),
или low_price > high_price, или любой bound отрицательный — результат
не кэшируется и возвращается None (graceful). Защита от garbage-ответов
API (999_999 < min, 9_999_999_999 > max).
Новые settings: cian_valuation_min_rub=500_000, cian_valuation_max_rub=500_000_000.
Тесты: 11 новых тест-кейсов в test_cian_valuation.py. Пофиксен pre-existing
KeyError в test_cache_hit_returns_cached (missing low_price/high_price в mock).
FIX 1: в _parse_html добавлен гео-фильтр per-card source_url. При
avito_serp_ekb_only=True (ENV AVITO_SERP_EKB_ONLY, дефолт True) карточки без
/ekaterinburg/ в source_url отбрасываются — Авито добивает выдачу
«по всей России» при малом числе ЕКБ-результатов (rooms=4 давал 96% не-ЕКБ).
Карточки без распознанного city-slug пропускаются консервативно.
Лог: «avito SERP: dropped N non-EKB cards (padding)».
FIX 2 (анализ): ROOM_SLUGS уже содержит отдельные бакеты «4-комн.» и «5+комн.»
(разбиты ранее). rooms-значение берётся из текста заголовка карточки
(_extract_rooms_from_title: regex «(\d)-к. квартира»), а не из бакета —
4/5/6 различаются по факту парсинга. Сплит slug'ов был сделан ранее, регрессий нет.
Тесты: 4 новых unit-теста в test_avito_ekb_geo_filter.py покрывают:
EKB+non-EKB → только EKB; ekb_only=False → все проходят;
без city-slug → консервативно оставляем; все EKB → ничего не дропается.
- pyproject.toml: httpx[socks]>=0.27.0 — тянет socksio, socks5:// прокси в _probe_current_ip работает прозрачно
- admin.py list_scrape_runs_unified: status Literal["done","running","banned","zombie","failed","cancelled"] вместо str|None — невалидные значения → 422
- avito_houses.py save_house_catalog_enrichment: гард ext_id=0 + нет адреса → skip without DB touch; два id-less novostroyka URL не схлопываются в bogus avito:0 в house_sources
- тесты: test_unified_runs_invalid_status_422 + test_unified_runs_valid_statuses_200; test_save_house_catalog_enrichment_skips_zero_ext_id_no_address + *_with_address_persists
ceiling_height на detail-странице лежит в offer.building.ceilingHeight,
а не offer.ceilingHeight (всегда null) → было 0% покрытия. repairType
часто пустой, структурное значение приходит как offer.decoration
('preFine'/...) — читаем оба + добавлен preFine->needs_repair и
case-insensitive lookup в нормализаторе. kitchen/description пути уже
верны (offer.kitchenArea/offer.description) — низкое покрытие = мёртвый
CIAN_PROXY_URL, не маппинг. Регресс-тест на реальной карточке 330982715.
The geoportal serves a Russian national-CA (Минцифры) TLS cert absent from
httpx's default trust store → CERTIFICATE_VERIFY_FAILED, loader fetched 0.
Public read-only data → verify=False (same as the curl -k used in recon).
Avito leaks addresses with house number glued to district marker without
separator («…Савкова, 29р-н Академический»), breaking house-number extraction
and same-house matching (41 unmatched avito listings on one street).
_clean_address now inserts ", " between a house-number token (digits +
optional Cyrillic letter + optional /N|сN|кN|корпус|стр) and a following
marker (р-н, мкр, район, г., пос, снт, …).
- avito.py: idempotent _deglue_house_marker step (CSS/tail-strip kept)
- tests: de-glue positive/negative/idempotency (24 passed)
- data/sql/124_deglue_avito_addresses.sql: idempotent backfill for stored rows
normalize.py НЕ тронут (общий fingerprint матчинга, #1534).
Закрывает avito-часть #1773 (cian-без-номера + дедуп — отдельно, зона cian).
Detail backfill (run 217) hit 5 consecutive HTTP 429s and aborted at 19 enriched
because the detail fetcher only had a same-session 429 short-retry (no reconnect).
429s are persistent: keep-alive reuses one backconnect exit IP across sequential
detail fetches -> avito rate-limits it. Mirror the merged SERP 429 fix (#1769):
widen short-retry 4->8 and add up to 3 ephemeral-session reconnects (fresh exit IP)
on 429 exhaustion before raising. Caller session never touched (as with 403 path).
Run 216 recovered 403s (merged fix) but still banned on a 429 at page 36
(deep pagination, backconnect conn-limit). Widen the 429 retry budget + one
reconnect on exhaustion in _fetch_serp_html, and make fetch_all_secondary skip
a blocked bucket and continue rather than aborting the run; only N consecutive
blocked buckets (real hard ban) re-raises. Preserves hard-ban detection.
fetch_detail raised on the first 403/429, aborting the detail backfill (run 191
enriched only 48 then zombied) -> avito detail coverage stuck at 14% of active.
Mirror the merged SERP fix (#1765): on 403/firewall under the backconnect proxy,
rebuild an ephemeral session (fresh exit IP) and retry up to N before raising;
short-retry 429. Never close/rebuild the caller-provided shared session. Also
add the missing HTTP-200 firewall-interstitial check on the curl detail path.
Adds listings.card_hash (SHA-256 of volatile SERP-card fields) computed and
stored on every scrape. Skips the redundant per-day listings_snapshots write
when a listing's card is unchanged. listings.last_seen_at/is_active still
bumped on every sighting (delisting TTL). Lays groundwork for detail-refresh
gating (C2).
Adds since=date mode to fetch_all_secondary: per room x seed-bracket, paginate
sequentially newest-first and stop once cards fall below the watermark, skipping
deep pagination (and the 403 clusters it triggers). since=None keeps the exact
exhaustive bisection walk. No scheduler/schedule change here — wiring follows
in a separate PR.
PR #1764's reconnect-retry was dead code in prod: the gate excluded configs
with avito_proxy_rotate_url set, but prod has BOTH the backconnect SCRAPER_PROXY_URL
(what curl_cffi egresses through) AND a leftover changeip URL for the separate
auv/browser proxy. With max_rotations=0 neither path fired -> a single SERP 403
still aborted the sweep (run 212). The curl session always uses scraper_proxy_url,
so session-rebuild rotates the exit IP regardless of changeip config.
Under a backconnect rotating proxy (no changeip URL) a single HTTP 403 or
firewall interstitial aborted the entire avito_full_load sweep via
AvitoBlockedError -> mark_banned. Each new connection through backconnect
gets a fresh exit IP, so retry by rebuilding the curl_cffi session up to
_AVITO_403_MAX_RETRIES times before giving up. Legacy single-IP changeip
rotation and browser-mode paths unchanged. Mirrors existing 429 short-retry.
Route each scraper source (avito/cian/yandex/domclick) to its own camoufox
browser+proxy so they no longer wedge each other through a single global egress.
Feature-flagged (FEATURE_BROWSER_POOL_ENABLED, default OFF): with the flag off the
/fetch and /login paths are byte-for-byte the existing single-browser behavior.
When on, /fetch routes by body["source"] to a per-proxy browser via BROWSER_PROXY_MAP
(BROWSER_PROXY_AVITO/CIAN/YANDEX/DOMCLICK with legacy fallbacks), each guarded by its
own lazy-launched lock. /login stays single-browser in Phase 1.
BrowserFetcher gains a source arg (default avito) and sends it in the /fetch body;
all scraper callsites pass their source. No docker-compose/.env.runtime changes
(Phase 2, owner-gated).
Gate-API nests Yandex's per-offer valuation under predictions.predictedPrice,
not predictedPrice.predictedPrice (that key does not exist). _predicted_prices
read the wrong outer key, so predicted_price_rub/_min/_max were None for every
offer (prod: pp=0 across all 6189 yandex rows). Verified live against the
gate-API 2026-06-18.
The rich-field test fixture used the same wrong wrapper, so the test passed
vacuously. Updated _ENTITY_RICH_OWNER to the real predictions.predictedPrice
shape — with the old code the assertions now fail, confirming non-vacuity.
Replace the system-curl SOCKS5 subprocess transport with the shared
BrowserFetcher (camoufox). camoufox's real-browser fingerprint is not
tarpitted by yandex and does not burn the mobile-proxy IP; raw system-curl
got the proxy IP flagged.
One BrowserFetcher is opened per scraper session in __aenter__ and reused
across all page fetches. _http_get now fetches via the browser, extracts the
gate-API JSON from camoufox's HTML <pre> wrapper, and returns it as the body
of a _CurlResponse (status 200 on success, 0 on fetch/extraction failure) so
all existing callers and the tarpit retry/rotate logic keep working unchanged.
URL building, _parse_gate_json, pagination, combos and field mapping are
untouched. Removed the dead curl subprocess constants/method.
