+# Integration test: git clone & pull on a SeaweedFS FUSE mount.
+#
+# Verifies that the mount correctly supports git's file operations by:
+#   1. Creating a bare repo on the mount (acts as a remote)
+#   2. Cloning it, making commits, and pushing back to the mount
+#   3. Cloning from the mount into a working directory also on the mount
+#   4. Pushing additional commits to the bare repo
+#   5. Checking out an older revision in the on-mount clone
+#   6. Running git pull to fast-forward with real changes
+#   7. Verifying file content integrity at each step
+#
+# Usage:
+#   bash test-git-on-mount.sh /path/to/mount/point
+#
+# The mount must already be running. All test artifacts are created under
+# <mount>/git-test-<pid> and cleaned up on exit (unless TEST_KEEP=1).
