- Move Base to app/models/base.py so alembic env.py can import it without triggering engine creation (which connects to hardcoded DB) - Update all 13 models to import Base from app.models.base - Pin golangci-lint to latest (supports Go 1.25) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
