54a5d13c48 feat(tradein/domclick): enrich Layer A SERP parser — description, repair-inference, minhash, seller

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)

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)

8d5c1a888d perf(estimate): trigram expression index for same-building anchor Tier A (~94x)

CI / openapi-codegen-check (pull_request) Has been skipped
_fetch_anchor_comps Tier A runs on EVERY /estimate (flag
estimate_same_building_anchor_enabled defaults True, not overridden in prod).
Its address predicate wraps address in lower(translate(address,'ёЁ','ее')) for
both the LIKE '%street%' and the ~house-number regex — non-sargable, and the
existing listings_address_trgm_idx is on the RAW address, so the planner
seq-scanned all ~66.7k listings (167ms, 15801 buffers) every estimate.

Add a GIN trigram expression index on lower(translate(address,'ёЁ','ее'))
matching the predicate exactly (gin_trgm_ops serves both LIKE and the regex).
Prod EXPLAIN (BEGIN/ROLLBACK, "Хохрякова 48"): 167ms -> 1.77ms (~94x), buffers
15801 -> 97. Independently dry-run-verified: Bitmap Index Scan, 0.66ms.
Result-identical (pure access-path; count/sum/min/max unchanged). No code
change (expression matches the predicate). ~8MB, sub-second build.

Other estimate-path queries confirmed already optimal (Tier W/H geom+rooms
BitmapAnd, Tier S house_id_fk) — no other index warranted.

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.

Migration 130 only filled house_id_fk for listings carrying
house_source/house_ext_id. Prod (2026-06-27): 1884 active NULL-FK rows
remain, 0 with house_source/ext_id (130 re-run = no-op). They were
matched via the per-listing-identity path the realtime mirror uses when
no house catalog id exists: match_or_create_house(ext_source=source,
ext_id=source_id) -> Tier-1 house_sources lookup (confidence 1.0).

136 replays that exact lookup offline: UPDATE listings SET house_id_fk
= house_sources.house_id WHERE (ext_source=source, ext_id=source_id) and
house_id_fk IS NULL. Faithful to base.py:704-750; idempotent (NULL
guard); deterministic (no fuzzy/geo); collision-safe (catalog ids live
under distinct ext_source like 'cian_newbuilding'). Dry-run BEGIN/ROLLBACK
fills 4608 NULL-FK rows (744 active), restoring estimator Tier-S
"same-building" grouping. The remaining ~1140 active need re-scrape/
re-match (scraper coverage — #1781 Лёха).

Classify tradein-browser sidecar HTTP 500/503 in _fetch_serp_html_browser and route into existing rotation/retry machinery: soft-ban → IP rotation, transient → bounded backoff, both exhausted → AvitoRateLimitedError (graceful mark_banned, partial preserved) instead of mark_failed. Fixes run-#356 class where one late 500 nuked a run that had saved 3186 listings.

Включает wide-corridor disclosure (PR #1880, был default OFF) — но с
ИСПРАВЛЕННЫМ порогом по prod-данным.

Проверка на trade_in_estimates (60д): corridor_pct = (range_high-range_low)/
median_price имеет median≈0.48, p90≈0.93, p99≈1.38; **30.7% оценок > 0.6**.
Старый порог 0.6 прилепил бы caveat «дом разбит на секции» к ~трети оценок —
большинство НЕ split-дома (широкий коридор бывает от разных причин). Это была
бы ложная атрибуция (дезинформация).

- estimate_wide_corridor_threshold 0.6 → 1.2: genuine split-дома из аудита =
  148-170% (1.48-1.70) → 1.2 ловит только экстремальный хвост (>p99), не трогая
  нормальную оценочную неопределённость.
- estimate_wide_corridor_disclosure_enabled False → True (включаем после
  валидации). ENV-override сохранён (kill-switch).
- Формулировка смягчена: «дом разбит на секции» → «вероятно, дом разбит на
  секции разной этажности ИЛИ разнородный фонд» — мы ИНФЕРИМ split по ширине
  коридора, не доказываем структурно.
- Логика не тронута: фаерит только Tier A + corridor>threshold, только понижает
  confidence + дописывает explanation; point/median/range не трогает.

Тесты: обновлены default-ассерты (флаг ON, порог 1.2) + 2 behavioral boundary-
теста (фаерит при pct>threshold, НЕ фаерит при умеренном 1.045<1.2 — доказывает
что raise убрал false-positive flood). 13 passed.

Два P2-фикса в чувствительном estimator.py, оба за флагами.

DEDUP (estimate_radius_dedup_enabled, default ON):
radius-путь _fetch_analogs (Tier S-canonical/S-fallback/H/W) кэпил только
per-address (rn_addr ≤ MAX_ANALOGS_PER_ADDRESS=5), но (source,source_id)-дубли
делят один address и выживали на разных rn_addr рангах → раздували n_analogs
(prod 2026-06-23: yandex 48, cian 9, n1 5 excess). Добавлен rn_dup-window
PARTITION BY source, CASE(id:source_id|url:source_url|ctid) ORDER BY scraped_at
DESC + AND rn_dup=1 во все 4 тира — зеркалит anchor-dedup (:1556). CASE/ctid-guard
не схлопывает legacy NULL-source_id. ctid доступен (все тиры FROM listings
single-table). psycopg3: column::type (легально), bind-param :: отсутствует.

SPLIT DISCLOSURE (estimate_wide_corridor_disclosure_enabled, default OFF):
Tier A матчит по address-regex (намеренно — дом дробится на house_id), на
split-доме разной этажности comp_min..max растягивает коридор до 148-170%.
При corridor_pct > threshold (0.6) → понизить confidence на ступень + caveat
«дом разбит на секции разной этажности — оценка ориентировочная». НЕ трогает
point/median/range — только confidence+explanation. Helper _downgrade_confidence.
Default OFF (no-regress, включим осознанно). Merge house_id отклонён (recon:
вреден — Tier A намеренно обходит house_id-группировку).

Тесты: +22 (dedup 4 тира + семантика + psycopg3-regex guard; split disclosure
через реальный _run_estimate harness + does-not-touch-median/range + helper).
399 estimator passed, ruff clean, mypy pre-existing-only.

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).

41e9c820c9 fix(tradein/estimator): ghost-anchor invariant guard — n_analogs=0 forces low (audit #1871 P1.2)

CI / changes (pull_request) Successful in 7s
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
Audit #1871 P1.2: estimate 5fcc1e99 показывал confidence='high' при
n_analogs=0 (median 38.45M ₽, sources=['yandex_valuation']) при реальной
истории листингов дома 4.2-6.5M. По prod-DB это ЕДИНСТВЕННАЯ legacy-строка
от 2026-05-30, давно expired (TTL оценок = 1 день, все 66 high/medium-c-n<5
строк expired). Текущий mainline уже честен. Фикс — defensive invariant,
чтобы ghost не мог родиться снова из будущих external-valuation-blend /
rehydrate / migration путей.

Backend (estimator.py):
- helper _enforce_zero_analog_low(confidence, n_analogs, explanation, ...)
  форсит 'low' + caveat когда n_analogs==0 and confidence!='low'.
  Идемпотентен (low+0 → low без дубля caveat), не трогает high+N>0, реальный
  median внешнего сервиса сохраняется (fake-коэффициенты не вводятся),
  logger.warning для observability.
- Вызов перед сборкой AggregatedEstimate в estimate_quality (единственный
  уязвимый return-путь; _empty_estimate хардкодит low — структурно безопасен).
- +5 unit-тестов (high+0→low+caveat, medium+0→low, low+0 идемпотент,
  high+N unchanged, None-explanation).

Frontend (HeroSummary, HeroTransparency, history):
- effectiveConfidence = n_analogs===0 ? 'low' : confidence — defensive depth
  на случай legacy-rehydrate / контракт-drift. Caveat-текст из backend
  confidence_explanation (не хардкод). Type-safe (ConfidenceLevel).

Данные на 2026-06-21 (prod deals table, 49 791 записей):

  deals >800k = 13 штук (0.026%) — нерыночные outlier'ы, не легитимный премиум ЕКБ.
  listings p99 (is_active, <800k фильтр) = 392 795 ₽/м².

Вывод: DEAL_MAX_PPM2=800_000 НЕ срезает легитимный ЕКБ-премиум (p99.9 сделок=500k).
Значение NOT изменено — задокументировано в комментарии рядом с константой

af1d882745 fix(tradein): Mera-audit fix-3 — cross-source dedup в _fetch_price_trend
Один объект на avito_imv + yandex_valuation с разными ext_item_id создаёт
дубликаты в house_placement_history и double-count'ится в помесячной медиане.
Решение: CTE с DISTINCT ON (round(area_m2), floor, price, price_date) с
приоритетом avito_imv через CASE sort. Легитимные разные квартиры (разные
площадь/этаж/цена) не затрагиваются.

За флагом estimate_price_trend_dedup_enabled (дефолт True в settings).
False → точно старое поведение (backward-compat). Graceful: без изменений
в логике min_points и возврата None при недостатке данных.

Тесты: 6 новых тест-кейсов в test_estimator_price_trend_dedup.py (SQL содержит
DISTINCT ON, flag OFF не содержит, Source1 preferred, данные возвращаются корректно).

81ee864d80 fix(tradein): Mera-audit fix-2 — _is_plausible_deal floor edge + area/price guards
Ужесточает валидацию ДКП-сделок в _is_plausible_deal:
- floor < 1 или floor=0 → drop (floor=-5/0/999 из битого парсера)
- area_m2 задана и <= 0 → drop (нулевая/отрицательная площадь из битого парсера)
- price_rub задана и <= 0 → drop (нерыночная/техническая сделка)
- floor=None → допустимо (graceful, нечем судить)

Все новые параметры area_m2/price_rub keyword-only с дефолтом None →
backward-compatible для существующих вызовов. Caller _fetch_deals обновлён
для передачи area_m2/price_rub из данных сделки.

Тесты: 16 новых тест-кейсов в test_deals_sanitize.py (floor=-5, floor=999,
floor=None ok, area_m2=0 drop, price_rub=-1 drop и пр.).

50a72f030a fix(tradein): Mera-audit fix-1 — Cian valuation price sanity bounds
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).

_save_yandex_history_items теперь пропускает items с area_m2 is None или
area_m2 <= 0 (битый парс «0,5 м²» и пр.) перед сохранением в
house_placement_history. Грязь копилась в БД и искажала price_trend.

Estimator защищён NULLIF на уровне SQL, но фильтрация на входе надёжнее.

b6ea986134 fix(estimator): radius-path нижний floor от DKP-коридора (анти-undershoot)
Anchor-путь имеет hard floor от comp_min_ppm2×(1-tol). Radius-путь аналогичной
защиты снизу не имел — quarter-index-вниз или corridor-clamp могли занизить
median неоправданно (asymmetry).

Добавлен floor: если итоговый median_ppm2 < dkp_low_ppm2 × factor → поднять
до floor + лог. Только radius-путь (anchor_tier is None); без dkp_raw → no-op.
За флагами estimate_radius_floor_enabled (default True) и
estimate_radius_floor_factor (default 0.8).

352dfc8053 fix(estimator): asking_to_sold ratio tier по финальному headline
_get_asking_sold_ratio теперь вызывается ПОСЛЕ anchor/IMV-blend/quarter-index/
corridor-clamp, получая ФИНАЛЬНЫЙ median_ppm2 для tier-placement (#928 audit).

До фикса: tier резолвился по pre-anchor radius-медиане (~105k), но ratio
применялся к post-anchor headline (~300k) — несовпадение tier'а в premium-
сегменте. После: ratio берётся из того же tier, что и финальный headline.

Graceful: нет ratio → expected_sold_* = None, headline не меняется.

  (settings.avito_proxy_rotate_url) + settle-sleep
  (settings.avito_proxy_rotate_settle_s, default 9s), логирует old→new IP.
- В `run_avito_pipeline` (Steps 4/5/5b) и `run_avito_city_sweep` (Phase 4/5/5b):
  при достижении consecutive-block порога — сначала ротация IP, сброс счётчика,
  продолжение; только при исчерпании бюджета (enrich_rotations_done >=
  avito_proxy_max_rotations) — abort (bounded). #1820 graceful сохранён: один
  блок ниже порога ротацию не вызывает.
- Добавлено `avito_proxy_rotate_settle_s: float = 9.0` в config.py
  (ENV: AVITO_PROXY_ROTATE_SETTLE_S). avito_proxy_max_rotations был 4 (с #1731).
