In `@macgit/App/ReferenceComparisonController.swift`:
- Line 121: Update the revision-loading condition in the refresh flow to reload
revisions whenever reuseSnapshot is false, while retaining the existing
initial-load behavior when revisions is empty. Match the branch comparison
reload behavior so the “Choose Revision” menu reflects current refs after
Refresh.

Compare a tracked file or its parent folder against a commit, local branch, remote-tracking branch, or tag without checking out that revision. File Status opens a separate resizable comparison window whose viewport stays within the screen, so long diffs scroll without expanding a modal beyond the repository window.
Related to #15. The repository-browser entry point remains dependent on #14 and is not included here.
