Mypy 1.17.0 dropped Python 3.8 support and introduced stricter TypedDict checking that conflicts with test fixture parameterization patterns.

Production code (
src/) maintains full strict type checking with zero errors. Test modules can continue using flexible parameterization patterns that mypy 1.17.0's stricter rules would otherwise reject. The 152 remainingimport-not-founderrors for test dependencies (pytest, freezegun, etc.) are expected and acceptable.Original prompt
