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.
5a: _load_sber_index_series логирует warning если latest месяц серии
старее sber_index_max_age_days (дефолт 35) — расчёт не блокируется.
5b: AvitoImvSummary.thin_market (bool, дефолт False) — True когда
market_count < avito_imv_thin_market_threshold (дефолт 10). Все три
точки конструирования AvitoImvSummary обновлены. Warning при thin.
sigma=0 guard: safe_area_sigma2/safe_floor_sigma2 предотвращает div/0 при
нулевом sigma из конфига. Post-weight MAD-clip (estimate_sb_clip_after_weight,
дефолт True) выполняется ПОСЛЕ Gaussian weighting — видовые/топ-юниты
с высоким ppm² больше не выкидываются до учёта similarity. За флагом.
_fetch_price_trend(freshness_months) — новый параметр, дефолт из
settings.estimate_price_trend_max_age_months (6 мес).
WHERE scraped_at > now() - N months исключает устаревшие items
(yandex_valuation 2024 и т.д.) из house_placement_history fallback.
houses_price_dynamics (Source 1) не затронут. psycopg v3 CAST syntax.
Добавляет AggregatedEstimate.analog_tier — стабильный enum для фронта:
same_building (Tier A), micro_radius (Tier C), district (S/H/0), city (W),
null (нет данных). Фронт не парсит tier из explanation.
address_precision уже был в схеме (подтверждено: line 208). Explanation не
удаляется — фронт fallback'ает на него.
Якорь с confidence=low ИЛИ (n<gate_min_n И FSD>gate_max_fsd) не заменяет
headline — fallback на radius-median. Дефолты (min_n=3, max_fsd=0.20) не
режут здоровые якоря (n≥4, FSD<0.15 проходят). За флагом
estimate_sb_low_conf_gate_enabled (дефолт True). Логируется с причиной.

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

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).
#1786 merged before the test fix landed → main red on
test_geocode_uses_cadastral_before_yandex. The new geoportal house-match
tier runs first in geocode(); this legacy cadastral test must mock it to
None so it exercises the cadastral forward path (else the MagicMock db row
leaks through the new tier as lat=1.0).
The realtime FK mirror (base.py:607-616) only landed 2026-06-17 (e63b21e).
Listings matched into house_sources before that — notably 9205 cian novostroyki
frozen at 2026-05-31 — never had house_id_fk mirrored back, breaking the
canonical "same-building via house_id_fk" estimator path (93% of active cian
novostroyki had NULL fk citywide).
Add data/sql/130_backfill_listings_house_id_fk.sql: deterministic source-id
backfill via house_sources (ext_source, ext_id → house_id), idempotent
(WHERE house_id_fk IS NULL), no fuzzy/address fallback. Prod (read-only):
9235/9235 target rows resolve deterministically, zero unresolvable. One-time
backlog drain; future rows linked in realtime by the e63b21e mirror.
The Cian Valuation enrichment was the only ungated external call in
estimate_quality() — its internal curl timeout (~25s) blocks the whole
/estimate request on every cache-miss, intermittently pushing latency
past the gateway/patience window (perceived as 'сервис не считает').
Wrap it in _with_budget() (mirrors the existing Yandex-valuation guard):
on timeout it degrades to None — the same graceful path as a network
error — instead of stalling. New setting estimate_cian_valuation_timeout_s
(default 8.0s, env ESTIMATE_CIAN_VALUATION_TIMEOUT_S).
Tier A (same building) dropped cian listings tagged listing_segment='novostroyki'
even in delivered buildings where that tag marks owner resales/переуступки
(sale_type=free). Gated relaxation of the #1186 guard, Tier A ONLY: include
novostroyki rows iff the same house has secondary (vtorichka/NULL) listings AND
secondary_count >= primary_count — secondary-dominant signal of a delivered house.
Prevents a lone vtorichka + clustered developer-priced novostroyki from anchoring
on застройщик prices after MAD-clip drops the rare secondary (~27% overvaluation).
Pure-primary / primary-dominated houses keep the #1186 guard. Behind
estimate_sb_tier_a_allow_primary_if_secondary_present (default True).
Dedup duplicate active rows by (source, source_id) primary key (codebase canon,
namespaced id/url tags, source_url fallback) — collapses rows whose source_url
differs only by trailing slash / query-param (e.g. cian source_id=330047129 ×2).
Tier C / radius / asking_to_sold_ratio paths untouched. 84 unit tests pass.
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).
scrape_schedules had no interval column -> every source ran daily. Add
interval_days from default_params (default 1, backward-compatible) so
compute_next_run_at can schedule N days ahead. Set avito_full_load_exhaustive
to interval_days=7 (weekly full pass for last_seen/delisting + silent price
edits); avito_full_load stays daily incremental.
run_avito_full_load gains incremental_days param -> passes since= to the
(merged) incremental SERP engine. avito_full_load schedule flipped to
incremental_days=2 (shallow, date early-stop -> avoids deep-pagination 429
bans). New avito_full_load_exhaustive source runs the full walk weekly to
refresh last_seen (10-day delisting TTL) and catch silent price edits.
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.
