feat(tradein): daily asking→sold ratio refresh ( #648 S4)
...
Scheduled job recompute_asking_to_sold_ratios re-derives asking_to_sold_ratios
daily so the estimator's asking→sold correction doesn't go stale as nightly
ДКП deals import. TRUE-MIRROR refresh: DELETE WHERE district='' + re-run the
080 derivation INSERT...SELECT in one transaction (atomic, single commit) —
drops stale per-rooms rows that fall below the 30/30 threshold, which the 080
ON CONFLICT DO UPDATE seed would have left behind.
- app/tasks/asking_to_sold_ratio.py: sync task (run_in_executor); derivation
byte-identical to migration 080; returns/logs counters; rollback+mark_failed
+re-raise on error.
- scheduler.py: trigger_asking_to_sold_ratio_run + dispatch (mirrors #570 snapshot).
- migration 082: seed scrape_schedules enabled=true, window 06:00-07:00 UTC
(after rosreestr import), ON CONFLICT DO NOTHING.
- 26 tests.

SQL 050_search_optimization.sql:
- CREATE EXTENSION IF NOT EXISTS pg_trgm
- ALTER listings ADD COLUMN tsv tsvector GENERATED ALWAYS AS (...) STORED
- 10 indexes (geom GIST, composite, gin_trgm, GIN tsv, partial kadastr, ...)
- CREATE MATERIALIZED VIEW listings_search_mv (per-listing aggregated across sources)
- 5 matview indexes (UNIQUE on listing_id for REFRESH CONCURRENTLY)
Celery task tradein.refresh_search_matview:
- REFRESH MATERIALIZED VIEW CONCURRENTLY listings_search_mv (psycopg v3)
- Logged duration via logger.info
- Graceful try/except ImportError fallback (no celery_app.py in tradein-mvp yet)
- Beat schedule snippet in docstring for future wiring
Fixups (deep-code-reviewer 2026-05-23):
- h.ratings_count → h.reviews_count (alias house_ratings_count preserved)
- Strip +psycopg dialect prefix from DSN for libpq compat
