This includes:

- Logging and progress services.
- Problem generation services (aka the "problems API").
- User prompting services.
- Build options infrastructure.
- The console and CLI, as a specific implementation of these services.

The UI architecture module uses the core runtime architecture module. It provides APIs that are used by the other modules and platforms.
