Description

Type hints, as well as being good practice, enable IDEs like Visual Studio Code to provide relevant information about properties at the time of writing. We should annotate all non-inferable types in the codebase to aid this.

Research direction

Start by inventorying the Python codebase and identifying variables whose types cannot be inferred. Define the annotation scope before changing files, then verify that all non-inferable variables are annotated and that the codebase remains usable with the intended IDE support.
