I found a standalone build blocker: this PR is based on current main, but the new tests include local file system headers that are only introduced by PR #41 and are not present in this PR's base. Please either rebase this PR onto the local file system PR after it is ready/merged, or make this PR self-contained before merging.

This header does not exist on this PR's base (main at 445feeb...) or in this PR's diff; it is introduced by PR #41. As a result, PR #42 is not buildable as a standalone PR against its current base. Please either stack/rebase this PR onto #41 after that dependency is ready, or include/remove the dependency here.
