- app/models/: Printer, Filament, PrintJob, Todo, PricingConfig with full SQLAlchemy 2.x mapped columns and relationships - app/routers/: list + get-by-id endpoints for all five resources - app/db.py: SQLAlchemy engine + SessionLocal + get_db dependency - alembic/: env.py reads MYSQL_* env vars; 0001_initial_schema mirrors db.sql - alembic.ini: script_location configured, URL injected at runtime Since db.sql already created the tables, stamp the DB before running future migrations: alembic stamp head Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
