Добавляет sber_freshness_monitor по образцу deals_freshness_monitor:
staleness данных СберИндекса теперь видна на MONITOR-частоте, а не тонет
в per-estimate warning'ах estimator._load_sber_index_series (#audit-5a).

- app/tasks/sber_freshness_monitor.py: чистая evaluate_sber_freshness()
  (frozen-now, без БД) + check_sber_freshness() (один SELECT
  max(period_month) вторичного сегмента по региону, #R2-H1 фильтр как в
  эстиматоре; WARNING при stale, mark_done при алерте — это монитор, не
  сбой; mark_failed только при пустой таблице).
- app/services/product_handlers.py: _job_sber_freshness_monitor + Handler
  в build_product_handlers (run_in_executor, как deals-монитор).
- data/sql/180_seed_sber_freshness_monitor.sql: seed scrape_schedules
  (enabled, daily 09:00-10:00 UTC, lag_allowance_days=25).
- tests/test_sber_freshness_monitor.py: frozen-now (fresh/stale/границы) +
  FakeDB (fresh/stale/empty/кастомный lag) + свойства миграции + registry.

Порог алерта: sber_index_max_age_days (35) + lag_allowance (25) = 60д.
+25 — запас на инхерентный лаг публикации источника (1-2 мес), чтобы не
шуметь на штатном отставании. Прод 2026-07-12: max=2026-05-01, age=72д >
60 → alert=1.

f631af4de3 fix(tradein): city-scope ДКП-запросы — убрать oblast-контаминацию (C1+C2)

Миграция 177 залила +47183 ДКП-сделки по всей Свердловской обл. (66, 368 городов,
deals.city заполнен). Потребители deals матчат по имени улицы БЕЗ city-фильтра →
одноимённые улицы дешёвых городов области контаминируют ЕКБ-числа.

C1 — street-deals + ДКП-коридор (клиент видит СЕЙЧАС):
- estimator._fetch_dkp_corridor + api/v1/trade_in.get_street_deals: добавлен city-скоуп
  `city IS NOT NULL AND :address ILIKE '%'||city||'%'` (канонический deals.city как
  подстрока целевого адреса — self-normalizing, адрес всегда содержит город).
- Live-repro (Ленина, 2к, 12мес): median 52 908 → 118 052 ₽/м² (было занижение ~−55%).

C2 — дневной пересчёт asking→sold ratio (imminent, «выкупная» −29%):
- tasks/asking_to_sold_ratio: deal_side + deal_global скоупятся на ЕКБ (asking-сторона =
  listings покрыты скрейпом только по ЕКБ; в listings нет колонки city). Константа
  _ASKING_CITY_PATTERN. ask-стороны не трогаем.
- Live-repro (rooms=2): sold_median all-city 82 593 (ratio 0.622) → EKB 116 858
  (ratio 0.880). Предотвращает обвал «выкупной» на след. пересчёте.
- Когда появятся oblast-листинги (B1/B2) → заменить на per-city ratio через `district`.

Тесты: subset-тест 080↔refresh (mirror _drop_segment_guard прецедента для city-guard) +
позитивный тест скоупа; 125 passed вкл. regression-гейт (байт-зелёный — коридор заморожен
в фикстуре), expected_sold, idor, 781. Regression-гейт не затронут (dkp_raw — frozen kwarg).

app.services.scrape_pipeline (3734 строк) имел 0 runtime-импортёров — Part C убрал
последнего вызывающего (admin.py, scheduler_main.py уже на
scraper_kit.orchestration.pipeline). Удаление:

- backend/app/services/scrape_pipeline.py — удалён целиком

Тесты (18 файлов, импортировавших scrape_pipeline):

DELETE (чистая legacy-оркестрация, kit-эквивалент покрыт в
test_scraper_kit_pipeline_parity{,2}.py):
- test_scrape_pipeline.py, test_scrape_pipeline_proxy_pool.py (proxy-pool DB-lease
  вытеснен RealProxyProvider DI-адаптером, покрытым test_scraper_adapters_contracts.py)
- test_anchor_watchdog.py, test_ban_rotation_1790.py, test_provider_rotation_1848.py
- test_scraper_resilience_1949_1950.py, test_sweep_drain.py

CONVERT (parity-сравнение убрано, kit-only regression оставлен/усилен):
- test_scraper_kit_pipeline_parity.py, test_scraper_kit_pipeline_parity2.py —
  _drive_old убран, _drive_new стал единственной веткой; ассёрты на конкретные
  значения counters сохранены (это теперь основное regression-покрытие kit
  orchestration)
- test_sweep_imv_phase.py — 6 IMV-phase тестов (enrich_imv true/false/no-touched/
  crash/failed-counter/cancel) переведены на run_avito_city_sweep (kit) с DI
  (config/matcher/enrichment); enrichment.process_houses_imv_batch — инжектируемый
  Protocol-метод вместо прямого импорта app.services.house_imv_backfill

PARTIAL-EDIT (легаси sweep-behavior вырезан, admin/kit-DI/несвязанные тесты
оставлены):
- test_city_sweep.py — только retarget 4 импортов на scraper_kit.orchestration.pipeline
- test_cian_city_sweep.py, test_yandex_city_sweep.py — sweep-behavior секции удалены,
  admin endpoint тесты (уже kit-DI) + anchor-timeout/watchdog формулы (retarget import)
  оставлены
- test_domclick_sweep.py — sweep-wiring тесты удалены, Counters + _map_item оставлены
- test_avito_newbuilding_sweep.py — sweep-wiring тест #5 удалён, retarget
  NewbuildingSweepCounters
- test_pipeline_browser_routing.py — 3 run_avito_pipeline теста удалены, browser-routing
  на уровне fetch_detail/fetch_house_catalog/AvitoScraper не тронут
- test_scraper_proxy.py, tests/scrapers/test_avito_anti_bot.py — _avito_proxies()
  переведён на kit (DI-параметр вместо settings-patch); pipeline-level тесты удалены

Stale-комментарии (scrape_pipeline.py как текущая реальность) поправлены в
admin.py, avito_detail_backfill.py, house_imv_backfill.py, yandex_price_history.py,
scrapers/avito_detail.py + kit-пакете (orchestration/__init__.py, orchestration
/pipeline.py, providers/avito/detail.py — strangler завершён, легаси удалён).

grep -rn scrape_pipeline app/ scripts/ packages/ — только past-tense упоминания
("удалён в Part E1", "перед его удалением") + один historical footnote
(contracts.py:138, provenance-заметка "собраны grep'ом по ... .py").

Backend suite: 3088 passed, 6 skipped (известный flake test_search_cache_hit #2208 —
не регрессия). ruff check чист на всех изменённых файлах.

85059aeb1b refactor(tradein/scheduler): удалить legacy scheduler_loop + scraper-scheduling, kit единственный путь (#2397 Part C)
Топология подтверждена перед удалением (docker-compose.prod.yml): tradein-backend
(uvicorn app.main:app) — SCHEDULER_ENABLE=false; tradein-scraper (python -m
app.scheduler_main) — SCHEDULER_ENABLE=true + USE_KIT_SCHEDULER=true. Kit-путь
(_run_kit_scheduler → scraper_kit.orchestration.scheduler + product_handlers)
самодостаточен: не импортирует ничего из app.services.scheduler.scheduler_loop
или app.services.scrape_pipeline. Все НЕ-sweep джобы, которые kit-scheduler
диспетчерит через build_product_handlers, идут напрямую в app.tasks.*/
app.services.* (либо lazy-импортят import_rosreestr_dkp/_execute_cian_backfill
из scheduler.py) — мимо удаляемой legacy-машинерии.

app/services/scheduler.py: 2098 → 418 строк. Удалено: scheduler_loop,
get_due_schedules, reap_zombies, _claim_run, _defer_next_run_at, _spawn_tracked/
_drain_inflight/_inflight_tasks, все 27 trigger_*_run-функций, импорт
app.services.scrape_pipeline, константы SCHEDULER_TICK_SEC/ZOMBIE_THRESHOLD_HOURS
(достижимы были только через удалённый scheduler_loop-путь). Оставлено (живые
импортёры вне удалённого): compute_next_run_at + has_running_run (admin.py),
import_rosreestr_dkp + _execute_cian_backfill (lazy-импорты в
product_handlers.py — job-тела kit-handler'ов).

main.py: убран `from app.services.scheduler import scheduler_loop` + lifespan-блок
запуска (`if settings.scheduler_enable: asyncio.create_task(scheduler_loop())`);
прод-backend всегда шёл с SCHEDULER_ENABLE=false, так что это был мёртвый код.

scheduler_main.py: убрана ship-dark развилка #2192 (USE_KIT_SCHEDULER=false →
legacy scheduler_loop fallback) — _run_kit_scheduler() теперь безусловный путь.
Поле settings.use_kit_scheduler оставлено в конфиге (Settings extra="ignore"
защищает от startup-краха на leftover env var), но на ветвление не влияет.

app.services.scrape_pipeline: 0 runtime-импортёров в app/+scripts/+packages/
после этого PR (только тесты, которые Part E удалит вместе с самим файлом) —
подтверждено grep. scrape_pipeline.py не тронут (Part E).

Тесты: удалены test_house_imv_backfill_scheduler.py (100% legacy-триггер,
backfill_house_imv сервис покрыт в test_house_imv_backfill_browser_flag.py /
test_backfill_wave2.py) и test_kit_registry_completeness.py (parity-инвариант
против удалённого dispatch, дублирует test_scraper_kit_scheduler_parity.py).
Точечно вырезаны "Scheduler wiring" секции (trigger_fn_exists/dispatch_branch_
wired/runs_in_executor) из ~10 файлов, тестирующих сами task-функции — сами
task-тесты (SQL-shape, миграции, fake-db поведение) оставлены нетронутыми.
test_scheduler.py: 825 → ~90 строк (остались только compute_next_run_at-тесты).
test_scraper_kit_scheduler_parity.py: убрана golden-parity секция против
удалённого scheduler_loop (SOURCE_TO_OLD_TRIGGER/_drive_old_one_tick/
test_routing_parity_per_source), остальное (claim/reap_zombies/dispatch/
registry-shape тесты kit-модуля) сохранено — источник этих инвариантов не
app.services.scheduler, а сам scraper_kit.orchestration.scheduler.
test_scheduler_main.py: 2 теста, патчившие app.services.scheduler.scheduler_loop,
переведены на монкипатч sm._run_kit_scheduler (единственный путь после этого PR).
test_sweep_imv_phase.py:171-371 (6 прямых импортов run_avito_city_sweep из
scrape_pipeline) намеренно НЕ тронуты — Part E.

Verify: полный pytest 3179 passed / 6 skipped / 1 known-unrelated fail
(test_search_cache_hit, #2208, не связан с этим PR); ruff 0.7.4 чист на всех
изменённых файлах; `python -c "import app.main; import app.scheduler_main"` OK.

app/tasks/avito_detail_backfill.py imported _CHROME_HEADERS/_avito_proxies from
the legacy app/services/scrape_pipeline.py (the only two symbols it needed from
that module). scrape_pipeline.py is slated for wholesale deletion in Part E of
epic #2277 -- this severs the last dependency so that deletion won't break the
backfill task.

Source chosen: kit-reuse, not relocate. scraper_kit/providers/_base.py (#2358
Foundation) already extracted the identical building blocks while deduplicating
providers/avito/{serp,detail,imv}.py:
- DOCUMENT_HEADERS -- byte-identical dict to _CHROME_HEADERS (same 8 keys/values,
  Accept/Accept-Language/Cache-Control/Sec-Fetch-*/Upgrade-Insecure-Requests).
- http_proxies(proxy_url) -- same formula as _avito_proxies():
  {"http": url, "https": url} if url else None, just parameterized instead of
  reading settings.scraper_proxy_url internally (both resolve the identical
  settings singleton in production, so behavior is unchanged).

Kept the AsyncSession(...) construction inline (didn't switch to kit's
build_document_session helper) to preserve the existing
`app.tasks.avito_detail_backfill.AsyncSession` mock seam used by
tests/tasks/test_avito_detail_backfill.py -- swapping to the helper would call
curl_cffi's AsyncSession via scraper_kit.providers._base instead, silently
bypassing that patch target.

scrape_pipeline.py itself is untouched (kept its own copies, per Part E plan).

Full backend suite: 3276 passed, 1 known-unrelated fail (test_search_cache_hit,
#2208), 6 skipped.

eb564cfc01 feat(tradein/scraper-kit): migrate backfill-task imports to kit, Group C (#2310)
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.

Финальный PR issue #2045 (BE-3): GET /api/v1/trade-in/location-coef для
LocationDrawer. FDW foreign table -> локальное зеркало osm_poi_ekb_local
(TRUNCATE+INSERT, тот же паттерн что cad_buildings_local/cadastral_geo_match,

из Site Finder poi_score.py::compute_poi_weighted_top7 (CATEGORY_WEIGHTS as-is,
радиус 1200м для квартир вместо Ptica 2000м для участков). score->coef -
новая MVP-эвристика (0.95..1.05, не откалибрована на реальных дельтах).

Graceful fallback (не 500, не фабрикуем факторы): пустая/не отрефрешенная
osm_poi_ekb_local или отсутствие lat/lon у оценки -> coef=1.0, factors=[],
geo_source="unavailable".

Scheduler: source=osm_poi_ekb_refresh, daily, зарегистрирован и в боевом
dispatch (scheduler.py), и в kit-registry (product_handlers.py) - иначе
test_kit_registry_completeness падает на ship-dark инварианте (#2192).

Frontend wiring (mappers.ts/LocationDrawer.tsx) - вне scope, отдельная задача
после проверки endpoint'а curl'ом на деплое.

848e6d3bdd feat(tradein/scraper): cooperative SIGTERM-drain for graceful deploy (#1182 Phase 2)
Деплой (docker recreate tradein-scraper) шлёт SIGTERM с stop_grace_period=120s
(Phase 1). Раньше scheduler_main отвечал hard task.cancel() → бегущий scrape-unit
получал CancelledError посреди браузер-карточки → карточка гибла без COMMIT.

Теперь SIGTERM/SIGINT лишь выставляют кооперативный флаг; tick-loop и длинные
задачи опрашивают его на СВОИХ существующих between-unit checkpoint'ах,
докоммичивают текущий unit и выходят сами.

- app/core/shutdown.py: новый standalone-модуль (asyncio.Event + request_shutdown
  / shutdown_requested / wait_for_shutdown), без app-зависимостей → нет циклов.
- scheduler_main._run: SIGTERM → request_shutdown() вместо task.cancel(); ждём
  добровольного drain'а, safety-net wait_for(100s < docker grace) с fallback на
  hard-cancel для некооперирующей задачи.
- scheduler_loop: проверка флага в начале тика и после каждого dispatch — не
  reap/claim новые run'ы во время shutdown, выходим из loop'а.
- avito_detail_backfill: break на границе карточки рядом с budget-guard; snapshot
  pending-query идемпотентен → следующий run сам резюмит остаток.
- import_rosreestr_dkp: расширен is_cancelled checkpoint — drain делает mark_done
  (partial), не mark_cancelled; user-cancel семантика без изменений.

Без SIGTERM поведение идентично прежнему. reap_zombies не трогает drained-run'ы
(они mark_done, не 'running').

Tests: tests/core/test_shutdown.py, scheduler_main drain+timeout-fallback,
avito_detail_backfill partial-drain. 26 + 29 scheduler passed.

avito_detail_backfill (mode=browser) aborted prod run 458 with
attempted=5 enriched=0 blocked=5: the lat-null pending queue is dominated
by DEAD listings (404 — that's why they are stale coord-holes). In browser
mode a dead listing's 404 page ("Ошибка 404. Страница не найдена") has no
item-view, so _is_detail_soft_block returned True → AvitoBlockedError →
backfill counted it as `blocked` and the consecutive-block breaker aborted
the run before reaching live listings.

- New AvitoListingGoneError (subclass of common AvitoError, NOT of
  AvitoBlockedError/AvitoRateLimitedError) so the backfill block-trap
  does not catch it.
- New _is_detail_not_found() detector + browser-mode branch in fetch_detail,
  checked BEFORE firewall/soft-block (keyed on the 404 title so it does not
  swallow the generic soft-block deflect). Curl path unchanged (404 → 302/
  non-200 → ValueError → failed, as before).
- Backfill: new `gone` counter; dedicated except AvitoListingGoneError branch
  that is neutral to the consecutive-block breaker and marks the listing
  is_active=FALSE (SAVEPOINT) so it leaves the snapshot scope.

Tests: unit for _is_detail_not_found (404 True; soft-block/item-view/empty
False), browser-mode fetch_detail raising AvitoListingGoneError (not Blocked),
and backfill gone-row marks inactive without aborting the breaker.

CI / openapi-codegen-check (pull_request) Has been skipped
The chunked matcher paged the candidate set with OFFSET over the very predicate
it mutates (building_cadastral_number IS NULL). Matched rows drop out, so OFFSET
(reset to 0 OR advanced) skips un-processed rows: once >= batch_size unmatched
listings (beyond threshold) accumulate at the low-id front, the chunk matches 0
and the loop breaks early, leaving higher-id matchable listings unfilled.
Counterexample (batch=3, matchable ids 1,4,7,10): matches 1 and 4 then breaks,
missing 7 and 10. Unit tests used single-chunk fixtures so never caught it.

The full UPDATE is ~5s for ~41k listings, so replace the loop with ONE set-based
LATERAL KNN UPDATE over all candidates — correct and fast. batch_size kept in the
signature for schedule-param compat (now unused).

edd187b47f feat(cadastral): geo-nearest building matcher via local cad mirror
Backfill listings.building_cadastral_number (was 0%) from the nearest
cadastral building. gendesign_cad_buildings is a postgres_fdw foreign table
with no geom — a per-listing FDW nearest query is ~1.16s/row (~13h for 43k
listings). Instead materialize the FDW once into a LOCAL cad_buildings_local
table (Point geom + GIST), then run a fast local KNN nearest-neighbour join.

Perf: the distance gate uses geometry-space ST_DWithin(geom, point, deg) (GIST
index, no geography cast) + geom <-> KNN order + ST_DistanceSphere metric
recheck on the single nearest row. A geography-cast ST_DWithin in the WHERE
defeated the index (58s+, full update never finished); the geometry-gate design
does the whole ~41.9k-listing UPDATE in ~5.4s (refresh+match ~7s end-to-end),
matching 16027 listings at 50m across 2229 distinct buildings.

The match is GEO-NEAREST (approximate): a street-level-geocoded listing matches
the nearest building within threshold_m (default 50m), not necessarily its exact
cadastral building. Exact cadastral + parcel-containment deferred (cad_parcels
FDW not exposed). Threshold is logged.

- 124: cad_buildings_local table (empty) + GIST. Migration does not read the FDW
  (deploy-independent); populated by the refresh job.
- 125: scrape_schedules seed source=cadastral_geo_match, enabled, next_run_at
  tomorrow 09:00 UTC (after geocode_missing).
- tasks/cadastral_geo_match.py: refresh_cad_buildings_local (bulk FDW scan),
  match_listings_to_buildings (chunked LATERAL KNN UPDATE), run_cadastral_geo_match
  run-lifecycle wrapper.
- scheduler: trigger_cadastral_geo_match_run + dispatch (sync DB-only, executor).

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).

YandexDetailScraper.fetch_detail использует plain httpx (BaseScraper._http_get)
без прокси и без TLS-fingerprinting → на датацентровом IP Yandex отдаёт капчу /
shell-HTML → parse всегда None → backfill 0% эффективен.

Замена: curl_cffi AsyncSession(chrome120 + scraper_proxy_url), идентично
yandex_address_backfill.py (доказано работающий путь на проде). HTTP 200 →
YandexDetailScraper.parse(html) (чистая функция, без сети). parse→None
считается fail (captcha wall); consecutive None → abort после max_consecutive_blocks.

Тесты обновлены: мокается AsyncSession.get + YandexDetailScraper.parse
(не fetch_detail). Добавлены кейсы: non-200 → abort, proxy=None → proxies=None.

a56420bdfb fix(tradein): wire nightly geocode backfill для listings в in-app scheduler

Root cause: 7674 avito/yandex/n1 listings з null-geom мають ненульовий address,
але geocode_tried_at IS NULL — OS cron геокодує тільки deals, ніколи listings.

Parts:
- geocode_missing.py: WHERE додає geocode_tried_at IS NULL OR tried_at < 7d
  (loop-safe); при failure (geo=None / exception) позначаємо tried_at=NOW().
  Новий run_geocode_missing_listings: batch loop з wall-clock budget (30m),
  update_heartbeat / mark_done / mark_failed lifecycle через scrape_runs.
- scheduler.py: trigger_geocode_missing_listings_run + dispatch elif.
- migration 110: seed scrape_schedules row (enabled=true, window 06-09 UTC).
- tests: оновлено 2 тести (commit на tried_at UPDATE); +7 нових тестів.
  1794 passed.

c9daf8e268 fix(tradein): yandex sweep — guard ext_id=NULL перед fetch_jk + cleanup httpx (#974 review M1/M3)

M1: добавлен guard перед вызовом fetch_jk — если ext_id пустой/None при наличии
jk_slug, логируем warning, incrementим failed_fetch и пропускаем (continue).
Пустой jk_id формирует битый URL /{slug}-/ и коллизию на UNIQUE ext_id=''.

M3: в admin.py /scrape/yandex-newbuilding заменён `async with YandexNewbuildingScraper()`
на прямое `scraper = YandexNewbuildingScraper()` — fetch_jk использует внутренний
BrowserFetcher, httpx-клиент BaseScraper открывался вхолостую.

Тесты: добавлен test_sweep_slug_present_but_ext_id_null_skips_fetch.
