Group E4 (final, highest-risk step of scraper_kit migration epic #2277):
estimator.py and house_imv_backfill.py's avito_imv/cian_valuation/
yandex_valuation call sites now import from scraper_kit.providers.* instead
of app.services.scrapers.*, following the exact wiring proven safe by E1/E2/E3
(#2334/#2335/#2336):
- estimator.py's avito IMV (_get_or_fetch_imv_cached, both call sites) and
house_imv_backfill.py's _process_one_house: add config=RealScraperConfig()
— kit's evaluate_via_imv silently drops the configured proxy without it.
- estimator.py's cian valuation (Stage 9): add config=RealScraperConfig() —
mandatory kwarg on the kit function (TypeError if omitted).
- estimator.py's yandex valuation: add config=RealScraperConfig() (mandatory)
and delay_provider=get_scraper_delay — without it kit silently falls back
to a hardcoded 5.0s throttle instead of the DB-configured anti-ban delay.
- All exception classes imported consistently from the same kit module as
evaluate_via_imv (not just the function) — mixing legacy/kit exception
classes would break `except IMVAddressNotFoundError` etc. via identity
mismatch (caught by an existing test that assumed the legacy class,
fixed alongside).
Observability: both cian_valuation and yandex_valuation graceful-degradation
except-blocks upgraded from logger.warning to logger.exception. GlitchTip's
LoggingIntegration listens at event_level=ERROR (main.py/scheduler_main.py) —
a WARNING never reaches GlitchTip as an event regardless of exc_info, so a
future config-wiring mistake at these call sites needs ERROR level to be
visible in monitoring.
house_imv_backfill.py: RealScraperConfig is imported lazily inside
_process_one_house (not at module level) to avoid a circular import —
app.services.scraper_adapters imports backfill_house_imv/
process_houses_imv_batch from this module at module level. Verified via
direct import in both orders plus a full `app.main` import.
Also fixes a stale docstring claiming process_houses_imv_batch is "not wired
into scheduler" — it is, via scrape_pipeline.py's run_avito_city_sweep.
Test updates: 2 pre-existing tests (test_backfill_wave2.py) mocked the legacy
IMVAddressNotFoundError/IMVEvaluation/IMVGeo classes, now updated to import
from scraper_kit to match the production exception identity. Added
config=/delay_provider= regression-guard asserts to the relevant estimator
and backfill tests, mirroring the existing #2306 cian_price_history pattern.
Legacy app/services/scrapers/{avito_imv,cian_valuation,yandex_valuation}.py
are untouched and still imported by cian_history_backfill.py's valuation
block (separately scoped, not touched here) — revert is a clean single-commit
revert, no schema/data migration involved.
Migrates legacy app.services.scrapers.* imports to scraper_kit equivalents for
house_imv_backfill.py, avito_detail_backfill.py, cian_history_backfill.py,
ekb_geoportal_ingest.py, and yandex_detail_backfill.py, proving parity via
tests/support/parity.assert_parity per the epic's gate (#2304).
newbuilding_enrich_backfill.py and yandex_newbuilding_sweep.py are left fully
on legacy imports: both call into scraper_kit.providers.{cian,yandex}.newbuilding,
which construct BrowserFetcher(source=...) without the now-mandatory endpoint=
kwarg (issue #2322, verified still open against the actual provider source, not
just issue status) -- no caller-side fix is possible, matching Group A's (#2305)
precedent for the same bug in admin.py.
Config-gated kit function footguns found and fixed (Group B #2306 pattern):
- avito fetch_detail's backconnect-on-403 retry silently drops when config=
is omitted -- now passes config=RealScraperConfig() explicitly, with a
regression test proving the gate.
- kit AvitoScraper's constructor now requires ScraperConfig positionally --
wired via RealScraperConfig(), which _rotate_ip() reads for
avito_proxy_rotate_url.
- BrowserFetcher(source=...) call sites (house_imv_backfill, avito/cian
detail backfills) now pass the mandatory endpoint=settings.browser_http_endpoint.
New footgun discovered (NOT #2322, flagged for follow-up): kit's
build_warmed_session() builds its curl_cffi session via _build_detail_session()
with no config parameter at all, unlike fetch_detail -- migrating it would
silently drop the sticky MGTS-proxy egress on avito_detail_backfill's
warm-batch path (the prod default). Left build_warmed_session/
_AVITO_WARM_SEARCH_URL on legacy imports, documented inline.

Group A of the scraper_kit migration epic (#2277). Switches admin.py's manual
"run parser" debug endpoints and scripts/ingest_domclick_jsonl.py from direct
app.services.scrapers.* imports to their scraper_kit.providers.* equivalents,
using the DI adapters (RealScraperConfig/RealMatcherAdapter/RealProxyProvider,
app.services.scraper_settings.get_scraper_delay) already established by
app.scheduler_main._run_kit_scheduler.
Migrated: /scrape (AvitoScraper/CianScraper/YandexRealtyScraper + save_listings),
scrape_avito_house, scrape_avito_detail, scrape_avito_imv, scrape_yandex_detail,
scrape_yandex_valuation, scrape_cian_detail, cian_auto_login's BrowserFetcher.
scripts/ingest_domclick_jsonl.py: ScrapedLot/save_listings + (now that #2307/
Group D ported a kit equivalent while this was in flight) DomClickDetailEnrichment/
save_detail_enrichment.
Deliberately NOT migrated (documented in admin.py): scrape_yandex_newbuilding /
scrape_cian_newbuilding — their kit equivalents
(providers/{yandex,cian}/newbuilding.py) construct an internal BrowserFetcher(...)
without the mandatory `endpoint` kwarg, so any call crashes/silently-fails
regardless of caller-side DI. Bug lives in scraper_kit provider code, out of
scope here (only consuming, not touching provider logic) — flagged as follow-up.
Parity proven via tests/support/parity.py (assert_parity) against the exact
functions each debug route now calls, on offline fixtures — no live network/DB.
Refs #2305
Group B of the scraper_kit migration epic (#2277): switch the three files'
internal dependency imports from legacy app/services/scrapers/* to their
byte/structurally-identical scraper_kit equivalents, proven via the new
parity harness (tests/support/parity.assert_parity, #2304). Public API of
all three files is unchanged, so no callers needed updating.
- cian_price_history.py: fetch_detail/save_detail_enrichment now from
scraper_kit.providers.cian.detail. Wires config=RealScraperConfig() at
the call site — kit's fetch_detail only reads cian_proxy_url when an
explicit config is passed, unlike legacy's always-on settings read;
without this the admin-triggered backfill would silently drop its
datacenter-IP proxy (#806) after the import swap.
- cian_session.py: extract_state now from scraper_kit.cian_state_parser
(byte-identical to legacy).
- yandex_price_history.py: ScrapedLot now from scraper_kit.base
(byte-identical fields/methods; record_yandex_price_history only reads
lot.* via duck-typing, no isinstance checks).
New tests/test_scraper_kit_pricehistory_session_parity.py proves the
migration delta specifically (extract_state, ScrapedLot.model_dump(),
fetch_detail+DetailEnrichment with config injection, and the own-session
proxy-kwarg wiring). Full backend suite passes (3145 passed, 6 skipped,
1 pre-existing unrelated failure confirmed on unmodified forgejo/main).
Финальный PR issue #2045 (BE-3): GET /api/v1/trade-in/location-coef для

- listings.phones: миграция 166 обнуляет данные; cian.py + scraper-kit
serp.py (golden-parity зеркало) перестают читать offer.get("phones") на
входе — write-path выключен у источника, колонка/поле в модели остаются.
Мёртвая запись "phones" в LISTING_FIELD_PRIORITY убрана.
- trade_in_estimates.client_name/client_phone: миграция 167 дропает колонки;

(основной путь + _empty_estimate), frontend TradeInEstimateInput и
CRM-блока EstimateForm (поля "Имя клиента"/"Телефон").
- sentry_scrub.py и management_companies.phones не тронуты — вне scope.
/me теперь отдаёт display_name/org/email (kopylov -> "Копылов", остальные None).

Fixed ANCHOR_TIMEOUT_SEC=240 guillotined every cian anchor when running via
USE_PROXY_POOL_BROWSER=true: each SERP fetch goes through camoufox with relaunch
on proxy swap (13-45s/page), and an anchor = 4 room-buckets x pages_per_anchor
SERP fetches + detail_top_n details + houses-enrich >> 240s. save_listings never
ran, lots_fetched=0, and after 3 consecutive skips the run was mark_banned.
Introduces _cian_anchor_timeout_s() mirroring the avito/yandex/domclick scaling
pattern: max(ANCHOR_TIMEOUT_SEC, buckets*pages*(delay+per_serp) + details*per_detail
+ houses_budget). Defaults -> 1580s worst-case watchdog (hang guard, not expected
duration). Applied to both the scraper-kit copy (strangler target) and the active
app.services.scrape_pipeline copy that run 581 actually hit.
estimate_dedup_analogs_enabled: False → True. Бэктест #1966 OFF vs ON
accuracy-идентичен (MAPE 13.89%, coverage 83.33%, bias −3.83%, median
width/cv без изменений) — включение меняет только user-visible n_analogs:
перестаёт быть раздутым кросс-постингом одного физлота на avito+cian+domklik
×3. Откат — ENV ESTIMATE_DEDUP_ANALOGS_ENABLED=false.
Тесты разведены default vs explicit (не ослаблены):
- test_estimator_dedup_cross_source_2087: добавлен test_dedup_default_is_on
(без monkeypatch — дедуп активен по умолчанию); test_dedup_flag_off_is_noop
оставляет ЯВНЫЙ OFF-override.
- test_backtest_regression_gate: пиним флаг OFF — гейт это байт-идентичный
replay frozen OFF-capture (recorded call-sequence фикстуры без дедупа); с
ON _dedup_cross_source триммит listings до quarter_indexes_lookup и
control-flow расходится с записью.
- test_estimator_n_analogs_priced (autouse) + test_radius_path_n_analogs_unchanged:
пиним OFF — инвариант «n_analogs = число priced-аналогов»/radius-passthrough
ортогонален дедупу, а синтетические аналоги делят адрес/этаж/площадь и
схлопнулись бы как кросс-посты.
