"""Offline unit tests for YandexCitySweepCounters + admin sweep endpoints (#861).

Pure & fast: NO live network, NO DB.

Legacy `run_yandex_city_sweep` orchestration behavior (SERP→save per-combo,
address-enrich phase, cooperative cancel, consecutive-SERP-failure abort, bounded
retry / combo-skip logging) удалён вместе с `app.services.scrape_pipeline` (#2397
Part E1) — эквивалентная regression-coverage теперь в
`test_scraper_kit_pipeline_parity2.py::test_yandex_city_sweep` (kit
`run_yandex_city_sweep`).

Coverage:
  - YandexCitySweepCounters корректно заполняются (dataclass shape)
  - Combos watchdog timeout существенно больше ANCHOR_TIMEOUT_SEC (arithmetic-only;
    `DEFAULT_PRICE_RANGES`/`ROOM_PATH` — kit `scraper_kit.providers.yandex.serp`,
    ретаргетировано с удалённого `app.services.scrapers.yandex_realty`, #2397 Part E2)
  - Admin endpoints (start/cancel/list-runs) — kit sweep вызван с DI
    (config/matcher/enrichment)
