- Migrate from SQLite to PostgreSQL with normalized schema - Add 11 lookup tables (fuel_type, body_type, drivetrain, transmission, materials, position_part, manufacture_type, quality_tier, countries, reference_type, shapes) - Rewrite dashboard/server.py (76 routes) using SQLAlchemy text() queries - Rewrite console/db.py (27 methods) using SQLAlchemy ORM - Add models.py with 27 SQLAlchemy model definitions - Add config.py for centralized DB_URL configuration - Add migrate_to_postgres.py migration script - Add docs/METABASE_GUIDE.md with complete data entry guide - Rebrand from "AUTOPARTS DB" to "NEXUS AUTOPARTS" - Fill vehicle data gaps via NHTSA API + heuristics: engines (cylinders, power, torque), brands (country, founded_year), models (body_type, production years), MYE (drivetrain, transmission, trim) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
