radius_m (schema + estimate_quality comp-search) уже в main (e23dabe4). Здесь —
остаток: два derived-роута принимают radius_m как optional query-param.

- GET /estimate/{id}/house-analytics и /sell-time-sensitivity: += radius_m
  (int|None). None → байт-идентичная авто-логика (расширение до 300 м только при
  <8 in-house записей). Задан → явный радиус расширения выборки домов, клампится
  в [100,5000], возвращается в radius_m ответа.

24b107ddb5 feat(tradein): #2043 BE-1 — surface cv/source_counts/created_at + /history.sources_used + cache-KPI
Данные уже считаются в estimator — отдаём наружу для /trade-in/v2 (снимает
approximate-флаги CV / счётчиков источников / даты отчёта / «ИСТОЧНИКОВ N/7»).

- AggregatedEstimate += cv (float|None), source_counts (dict[str,int]), created_at.
- estimator: _cv_from_ppm2 / _source_counts helpers. cv прокинут через
  PricingResult — anchor-путь берёт CV комплов (anchor["cv"]), radius-путь — CV
  радиусной ₽/м²-выборки. source_counts считается по ПОЛНОЙ выборке (metadata_lots)
  до top-N отсечки. created_at = момент создания.
- POST /estimate возвращает все три; GET /estimate/{id} пересчитывает cv/
  source_counts из сохранённых analogs (best-effort) + created_at из колонки.
- /history: += sources_used (jsonb) в проекции → колонка «ИСТОЧНИКОВ N/7».
- /cache-stats: += avg_median_price (по median_price>0) + repeat_address_pct
  (доля строк с неуникальным address). Честный best-effort по persisted-оценкам.

Серия sale-share data-quality (по находкам юзера):

  guid-независимо) — резолвит дома где gar_house_guid ≠ ЖКХ houseGuid

Extend the cooperative shutdown-drain (Phase 2) to the long sweep and
full-load loops in scrape_pipeline.py so they stop CLEANLY on SIGTERM
instead of being hard-cancelled at the 80s _drain_inflight timeout.

At every between-unit checkpoint that already polls scrape_runs.is_cancelled
(user-cancel) we add an ALONGSIDE shutdown_requested() branch:
  - anchor-loop sweeps (avito/yandex/cian city) + avito newbuilding +
    domclick pre-SERP: update_heartbeat + mark_done(partial) + return;
  - full-load on_bucket callbacks (cian/yandex/avito): raise a distinct
    RuntimeError("shutdown") sentinel, handled next to the existing
    "cancelled" sentinel -> mark_done(partial), skipping the detail phase;
  - cian full-load detail loop: break -> existing post-loop mark_done.

Drain finalizes as mark_done(partial), NOT mark_cancelled (that stays
user-cancel only). is_cancelled -> user-cancel semantics are unchanged, and
behaviour is identical when shutdown_requested() is False. No resume_cursor
or paused status yet (Phase 3b, deferred): this is drain-coverage only.

Tests: tests/test_sweep_drain.py covers both structural variants -
run_avito_city_sweep / run_cian_city_sweep (anchor-loop) and
run_avito_full_load (on_bucket sentinel): shutdown flips True after the
first unit, asserting the sweep stops at the checkpoint, calls mark_done
with partial counters, never calls mark_cancelled, and does not process
later anchors/buckets/phases.

566b2f9617 fix(tradein/scraper): drain detached run-children on SIGTERM, not just coordinator (#1182 Phase 2)
All checks were successful

CI / openapi-codegen-check (pull_request) Has been skipped
Pre-push review: _await_scheduler ждал только scheduler_loop COORDINATOR, но вся
scrape-работа крутится в detached asyncio.create_task детях (каждый trigger_* делал
`task = create_task(_run())` без join). На SIGTERM coordinator выходил из while True
и завершался → asyncio.run() teardown хард-кансельил ещё бегущих детей mid-await =
ровно #1182 failure mode. Кооперативный checkpoint спасал ребёнка лишь когда его
residual-время случайно перекрывало drain — вероятностно, не гарантированно.

Fix — coordinator теперь дренажит детей перед выходом:
- _spawn_tracked(coro): централизованный detached-spawn, кладёт задачу в module-level
  registry _inflight_tasks (strong-ref = RUF006 keep-alive) + done-callback ретривит
  exception и убирает из set'а. Заменил 26 одинаковых
  `task = create_task(_run()); task.add_done_callback(...)` сайтов.
- _drain_inflight(): один asyncio.wait по живым детям с бюджетом
  _CHILD_DRAIN_TIMEOUT_S=80s (< scheduler_main 100s < docker grace 120s). Кооперативные
  дети (avito_detail_backfill, rosreestr-executor) дочекивают карточку/батч + mark_done
  и резолвятся; некооперативные упираются в timeout и падают на внешний hard-cancel.
- scheduler_loop по выходу из tick-loop (только по SIGTERM) зовёт await _drain_inflight().

NB: raw asyncio.all_tasks()-minus-self здесь НЕЛЬЗЯ — в нашей топологии он захватывает
_run parent-task (блокирован на wait_for(coordinator)) и shutdown_waiter → циклическое
ожидание coordinator↔_run, всегда упирающееся в timeout. Точный registry это исключает.

Tests: tests/test_scheduler.py — detached cooperative child drained-not-cancelled,
non-cooperative child timeout→left for hard-cancel, no-op без детей, scheduler_loop→drain
wiring. Обновил 3 source-inspection теста под новый _spawn_tracked паттерн.

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.

Capture extra bff-search fields in _map_item (verified live):
- description → ScrapedLot.description + infer_repair_state_from_text → repair_state
  (DomClick search has no renovation-enum; text inference like cian #622)
- sha1 description_minhash (cross-source dedup)
- agency_name from seller (defensive str|dict)
- raw_payload: is_sber_collateral, has_discount, discount_value, duplicates_offer_count, seller

Additive only; existing Layer A behavior unchanged. Deep card detail (renovation-enum,
wallType, full price-history, owners_count) is card-only = QRATOR-blocked on prod proxy
→ separate effort (needs dedicated residential IP).

52fc920507 fix(tradein/domclick): rewrite dead scraper to BFF JSON API + honest status (#1846, #1968)
Old HTML scraper dead: /search?city_id retired in DomClick redesign + VPS IP
QRATOR-banned (prod domclick_city_sweep reported done/0 every run). New path:

- GET bff-search-web.domclick.ru/api/offers/v1 + count/v1 via
  BrowserFetcher(source="domclick") -> generic provider -> shared mobile proxy
  -> bypasses QRATOR (prod-verified live: 20 items returned, no block).
- Sweeps 6 room buckets (st/1/2/3/4/5+); recursive binary price-split for
  oversized buckets (rooms=2 ~2215 > offset cap 2000); count/v1 sizes buckets.
- Maps SERP JSON -> ScrapedLot with lat/lon at ~100% (closes avito 54% NULL-lat
  gap); per-card EKB geo-guard.
- Honest status (#1968): QRATOR block OR fetch errors with 0 lots -> mark_failed,
  not mark_done. Parse failures are per-page resilient (break bucket, keep partial
  lots) so a transient bad page never aborts the whole sweep.
- Schedule shipped DORMANT (enabled=false, pages=100) via
  138_domclick_bff_rewrite_schedule.sql; operator enables after prod smoke.

42 scraper tests (price-split boundaries, parse-error resilience, honest status);
full backend suite green; ruff clean. Layer B (detail renovation/wallType/
priceHistory) deferred to #1846 follow-up.

2ea49b637f refactor(tradein/estimator): extract deterministic pricing into pure _price_from_inputs (#1966 foundation)
All checks were successful
CI / changes (pull_request) Successful in 6s
CI / backend-tests (pull_request) Has been skipped
CI / frontend-tests (pull_request) Has been skipped
CI / openapi-codegen-check (pull_request) Has been skipped
Behavior-preserving structural refactor: the ~870-line deterministic pricing
block inside estimate_quality() is extracted into a new pure synchronous function
_price_from_inputs() returning a PricingResult dataclass.

Key design decisions:
- All async DB fetches (imv_eval, yandex_val, cian_val) hoisted to estimate_quality
  BEFORE the call; passed as pre-fetched values / bool flags.
- DB-dependent helpers whose arguments are computed inside the block (_get_asking_sold_ratio,
  _lookup_quarter_index, _lookup_quarter_indexes) injected as Callable parameters
  (ratio_resolver, quarter_index_lookup, quarter_indexes_lookup).
- _fetch_house_imv_anchor called once in estimate_quality (was two separate conditional
  calls inside the block); single result passed as imv_anchor dict.
- _fetch_dkp_corridor and _fetch_anchor_comps hoisted to estimate_quality with
  identical guards.

All 2443 existing tests pass UNMODIFIED. 9 new hermetic unit tests added that
call _price_from_inputs directly with stub callables.

Два связанных фикса из диагностики 2026-06-27:

ФИКС C (run_cian_full_load, per-fetch timeout): monkey-patch _browser.fetch →
asyncio.wait_for(_f(url), timeout=cian_full_load_per_fetch_timeout_s=90s).
BrowserFetcher.fetch имеет httpx-timeout 120s, но browser-сервис иногда виснет
так что httpx не получает ответ (нет EOF) → fetch висит → asyncio.gather
блокирует весь bucket → heartbeat_at не обновляется → reap_zombies убивает живой run.
wait_for(90s) отменяет зависший fetch → TimeoutError → _fetch_page_html ловит
как Exception → None → _one_page → [] → gather завершается нормально.
За флагом (cian_full_load_per_fetch_timeout_s=0 = отключить, >0 = включить).

ФИКС D (background heartbeat): asyncio.create_task(_background_heartbeat())
обновляет heartbeat_at каждые 60s независимо от on_bucket/on_progress прогресса.
Без него пустые bucket или зависший gather замораживает heartbeat на несколько часов.
Task отменяется в finally → не течёт при return/raise/cancel.

Новая настройка (ENV):
  CIAN_FULL_LOAD_PER_FETCH_TIMEOUT_S=90.0  — timeout одного browser-fetch

757f6486f5 fix(scrapers): avito changeip-resilience (retry короткими попытками) + честный статус когда SERP отработал (#1950)
Два связанных фикса из диагностики 2026-06-27:

ФИКС A (_rotate_proxy_ip): вместо одношотного GET с timeout=30s — retry-loop
(proxy_rotate_attempts=3 попыток по proxy_rotate_attempt_timeout_s=8s каждая).
Зависший changeip-сервис больше не блокирует весь sweep на 30s.
Первый успешный attempt → True; все провалились → False (логируется как error).

ФИКС B (run_avito_city_sweep): когда SERP-фаза уже сохранила лоты
(lots_inserted + lots_updated > 0) и упала только detail/houses-фаза
(AvitoBlockedError / RateLimitedError), помечаем run как done (не banned)
при avito_serp_ok_not_banned=True (default). Метрика banned зарезервирована
для случаев где SERP сам заблокирован (0 лотов).

Новые настройки (ENV):
  PROXY_ROTATE_ATTEMPT_TIMEOUT_S=8.0   — timeout одной changeip-попытки
  PROXY_ROTATE_ATTEMPTS=3              — число попыток перед отказом
  AVITO_SERP_OK_NOT_BANNED=true        — флаг нового поведения (default on)

bcdc7ccb04 fix(estimator): deterministic comp tie-breaker + n_analogs counts priced analogs

Found by adversarial valuation audit (2 confirmed, bot-safe).

FIX A (#5): both radius comp queries (Tier H ~3990, Tier W ~4135) ended with
a bare ORDER BY relevance_score; on score ties Postgres returned rows in
undefined order, so the same /analyze could pick different comps across runs.
Append deterministic tiebreaker: relevance_score ASC, distance_m ASC,
scraped_at DESC NULLS LAST, id ASC (id = listings PK → total order). Added id
to each base CTE; outer projection unchanged (no leak downstream).

FIX B (#2): _filter_outliers keeps rows with price_per_m2 IS NULL, but the
median is built from prices_ppm2 (drops them) while n_analogs counted all of
listings_clean — overstating contributing comps ("Найдено N аналогов"
misleading; all-price-less -> median=0 but n_analogs>0). Count n_analogs from
prices_ppm2 in the radius path. #698 anchor overwrite + #691 zero-analog->low
guard unaffected; listings_clean itself not filtered.

Adds tests/test_estimator_n_analogs_priced.py (verified to fail on old code).
Audit also flagged velocity fan-out (false-positive: 0 duplicate domrf_obj_id
on prod) and >/>= disclosure tweaks (cosmetic) — deliberately not changed.

#1928 fixed scrape_runs.total_seen/new_count for sweeps via _column_counts
but only regression-tested the yandex mark_done path. Add equivalents for
the CitySweepCounters (avito/cian) sweep and the mark_failed path — both
explicitly named in the #1926 audit — so the all-sweeps + failure-path
guarantee is locked in.
