alembic-ini-hardcoded-db-url-triggers-secret-scanner

Hardcoded database URLs in alembic.ini (even dev URLs like postgresql://user:pass@localhost/db) trigger git secret scanners and block commits. Fix: leave the sqlalchemy.url key empty in alembic.ini and have alembic env.py read from the RSAME_DATABASE_URL environment variable at runtime. This is a recurring gotcha when scaffolding new Python/SQLAlchemy projects.
