p3 naming-consistency (cadastral cols 0% filled). Migration 094_cadastral_unify.sql
(idempotent DO-block IF EXISTS): drop+recreate listings_search_mv (MV) +
v_data_quality (view), RENAME deals/house_metadata kadastr_num->cadastral_number,
DROP listings.kadastr_num + listings_kadastr_idx. Code SQL-string renames in
search_query/estimator/base (Lot dataclass field NOT renamed). 240 tests pass.
WARN: destructive DDL auto-applies to prod on deploy -> MERGE-GATE post-demo.
Reviewer: verify recreated MV/view DDL vs LIVE pg_get_viewdef before apply
(reconstructed from migration history 050/046, not live capture).
