Is this the right issue type?

• Yes, I'm planning work for this project team.

Summary

To create consistent code - it would preferable to have MyPy running in CI as a check.

Currently this would fail as the codebase has plenty of errors in typing...! These are gradually being fixed, but might be at the point it could be captured in one shot.

Acceptance Criteria

• MyPy check runs on CI
• Code passes type checking
• Tests pass.

Tasks

• New workflow for type checking
• Fix any typing issues
