> bootstrap an Artifacts repo from an existing git repository

wow that's cool. I used to hack CF Worker to operate .git using isomorphic-git, it's a PITA.

> ArtifactFS runs a blobless clone of a git repository: it fetches the file tree and refs, but not the file contents. It can do that during sandbox startup, which then allows your agent harness to get to work.

That's insanely useful. How combining with only committing the file changed we'd have a single-blob editing capability against any .git
