Soft-block (HTTP 200 generic витрина без item-view) теперь детектится как блок → существующая 403/firewall reconnect-машинерия → ротация exit-IP вместо silent failed (blocked=0, enriched→0 каскад). + snapshot ORDER BY (lat IS NULL) DESC для приоритизации coord-holes (#1967, in-scope 321). Tests: test_avito_detail_soft_block.py. Full tradein suite 2591 passed.
- New task app/tasks/avito_detail_backfill.py with run_avito_detail_backfill()
* Single snapshot SELECT at start (guarantees termination)
* Same proxy/AsyncSession path as scrape_pipeline.py step 5
* Budget guard (budget_sec), consecutive block abort (mark_done not mark_failed)
* rotate_ip() on every AvitoBlockedError; rollback on generic Exception (#1368)
* start = time.monotonic() initialized before try so except can reference it
- Scheduler wiring: trigger_avito_detail_backfill_run() + elif in scheduler_loop()
- Migration 112: scrape_schedules INSERT window 09-12 UTC, batch_size=800,
budget_sec=3600, request_delay_sec=6, max_consecutive_blocks=5
- 7 unit tests (no pytest-mock, unittest.mock only): all 7 passing,
full CI suite 1809 passed
