"""Offline unit tests for run_yandex_city_sweep (SERP+address-enrich, #861).

Pure & fast: NO live network, NO DB. We monkeypatch:
  - YandexRealtyScraper.__init__ / __aenter__ / __aexit__ — avoid get_scraper_delay
    DB read + real curl_cffi session creation.
  - YandexRealtyScraper.fetch_around_multi_room — return a fixed list of fake ScrapedLot.
  - scrape_pipeline.save_listings — counter/no-op (no real listings table).
  - scrape_runs.* (is_cancelled / update_heartbeat / mark_*) — in-memory fakes.
  - curl_cffi.requests.AsyncSession — fake for address-enrich HTTP calls.

Asserts orchestration semantics:
  - SERP → save (all anchors, counters aggregated)
  - address-enrich фаза вызывается если enrich_address=True и есть source_ids
  - enrich_address=False → адрес-фаза пропускается
  - cancel → останавливает sweep
  - N consecutive SERP failures → mark_banned + abort
  - per-item address-enrich error не валит sweep
  - mark_done вызывается при нормальном завершении
