## Summary

- **Auth tutorial**: fix deprecated `datetime.utcnow()` →

`Exception` in chat example, add connection lifecycle section with close
codes, add rejected connection test example

`mapped_column()` / `Mapped[]` (SQLAlchemy 2.0 style with type checker
support)

`uv.lock` reference in production checklist

pattern-matching test examples
