Automatically closed - issue fixed for 2 weeks with no activity.

We are doing some issue management housekeeping and adding/removing components.

We are removing the "Code" component and want people to categorize issues with the best module/submodule component.

Moving this issue to "Miscellaneous" as I'm not sure where the best place is.

If we have a new project to move this to, we can optionally do that as a secondary step.

See 📌 Update AI module project components Active for more details.
