Issue #307 OBJ-2. Adds GIST trgm index on objective_lots.project_name so the LATERAL similarity() probe runs via bitmap index scan instead of seq-scan-per-row (database-expert worker identified this perf bottleneck via EXPLAIN). Composite score = name_sim*0.6 + dev_match*0.25 + district_match*0.15. Threshold composite >= 0.75 for auto-accept. ON CONFLICT (objective_complex_name, objective_group) DO NOTHING — idempotent. REFRESH mv_layout_velocity CONCURRENTLY after backfill (outside tx) so Site Finder sees new mappings immediately. Expected mapping count: 142 -> 200+ (realistic ceiling given Objective project_names vs DOM.РФ comm_names naming gap).
