• These type annotations use dict[str, ...], which raises TypeError: 'type' object is not subscriptable on Python 3.8 at import time (unless from __future__ import annotations is enabled). Since the project targets Python >=3.8, the annotations should be made 3.8-safe (e.g., quote them or switch to typing.Dict).
