+-- Audit 2026-05-17: bulk insert missing PRINZIP project mappings
+-- into objective_complex_mapping so mv_layout_velocity picks them up.
+--
+-- Problem: objective_corpus_room_month had active deals for these projects
+-- but no row in objective_complex_mapping → mv_layout_velocity JOIN skipped them.
+--
+-- Audit source: audits/SiteFinder_FixList_May17.md #4
+--
+-- UNIQUE constraint on table: (objective_complex_name, objective_group)
+-- MV join key: objective_complex_mapping.objective_complex_name = objective_corpus_room_month.project_name
+-- One domrf_obj_id per project_name; mapped to the largest/most active corpus.
+--
+-- Skipped:
+--   Парк Победы   — already mapped to obj_id=60160 (Строящиеся, PRINZIP)
+--   Парковый квартал — 0 deals/12m, inactive
+--   Первый        — belongs to ГК ИКАР, NOT PRINZIP; name collision, not a real match
+--
+-- After applying this migration run manually (post-deploy):
+--   REFRESH MATERIALIZED VIEW CONCURRENTLY mv_layout_velocity;
+-- See runbook: runbooks/Refresh_MV_Layout_Velocity.md
+--
+-- Dependencies: objective_complex_mapping (exists), mv_layout_velocity (refresh separately)
+-- Deploy: auto-applied by deploy.yml via _schema_migrations tracking.
+-- Idempotent: ON CONFLICT (objective_complex_name, objective_group) DO NOTHING
