Change location of Artifacts (walkthrough, implementation plan, etc)?

Antigravity currently stores the artifacts, such as the walkthrough file in ~/.gemini/antigravity/brain/UUID/... however, I would like to store these files in the current codebase so I can version them (git) together with the codebase. I would also like to see them grouped together so an agent at a later date can have all the context etc.

How can I change the location where Antigravity saves these files?
