+#### Renamed Files
+
+A rename touches two paths. Mergify treats it the way `git` does with rename detection
+turned off: the file is **removed** at its previous path and **added** at its new one.
+
+For `git mv critical/guard.txt ignored/guard.txt`:
+
+- `files` contains both `critical/guard.txt` and `ignored/guard.txt`
+- `removed-files` contains `critical/guard.txt`
+- `added-files` contains `ignored/guard.txt`
+- `modified-files` contains neither, even when the move also changed the file's content
+- `scope` reports the scopes owning both paths
+
+So `removed-files ~= ^critical/` matches a pull request that moves a file out of
+`critical/`, and a `-files ~= ^critical/` gate is not satisfied by one.
+
+`#files` is GitHub's own changed-file count, which counts a renamed file **once**. It
+therefore does not equal the length of `files` on a pull request containing a rename.

   Mergify rejects `barrier_files` in either case.
 
+A renamed file is matched at both of its paths, so moving a file *out of* a barrier pattern makes
+the pull request a barrier too: the barrier file is gone from the location you declared.

 You can also manage these patterns from the dashboard: the **Barrier files** editor in the queue
 configuration **Scopes** section edits the same `barrier_files` filters for file-pattern scopes.

+### Renamed Files Count at Both Paths
+
+A rename touches two paths: the file disappears from where it was and appears where it
+went. Mergify matches your patterns against **both**, so moving a file out of a scope
+reports that scope just as deleting the file would.
+
+With the multi-language scopes above, `git mv services/api/settings.py config/settings.py`
+reports **both** `python-api` (the path the file left) and `shared-config` (the path it
+arrived at). That matters when a scope guards something: a pull request that moves a file
+out of `services/api/` is a change to `services/api/`, so the `python-api` scope's CI jobs
+and batching rules apply to it.
+
+The same rule applies to `barrier_files`: renaming a file out of a barrier pattern makes
+the pull request a barrier, because the barrier file is gone from its declared location.

 ### Path Filtering vs Scopes
 
 GitHub Actions offers path filtering (`on.pull_request.paths`), but it has critical limitations in
