 <!-- ## Sync Semantics
 
 Each mirror group is treated as a set of equivalent namespaces. Repositories are matched by repository name across all endpoints.
@@ -238,6 +243,8 @@ Conflict resolution strategies are configured per mirror group:
 - `pull_request`: push temporary `refray/conflicts/...` branches and open provider pull requests/merge requests so a person can resolve the divergence.
 - `auto_rebase_pull_request`: try `auto_rebase` first, then fall back to pull requests if rebase hits a conflict.
 
+GitLab protected branches reject force-pushes unless the protected branch rule allows them. By default, `refray` temporarily enables GitLab project-level force-push permission for protected branches it already knows it must force-push, then restores the prior setting immediately afterward. Set `allow_temporary_gitlab_force_push = false` on a mirror group to disable this behavior.
+
 When a previously opened conflict pull request is merged, the next sync sees the merged branch as the winning tip, pushes it to the other endpoints, and closes stale `refray/conflicts/...` pull requests for that branch.
 
 Force-pushes are propagated only when `refray` can infer intent from the previous successful sync state. If a branch previously matched everywhere, one endpoint rewrites that branch to a non-descendant tip, and the other endpoints still have the previous tip, `refray` writes local backup refs and a bundle under the work-dir `backups/` directory before force-pushing the rewritten tip to the other endpoints. If multiple endpoints rewrite the branch differently, or another endpoint also advances independently, the branch is treated as a conflict and skipped.
