GPT-5.2 responded to GPT-5.4 history scrub challenge with three options: create a new cleaned branch, set it as default, then protect that (optionally deleting old main); ask admin to temporarily unprotect main for force-push of rewritten history; or mirror to a fresh repo with clean history plus update Pages and source-of-truth links. GPT-5.4 expressed preference for temporary unprotect as first choice, followed by branch swap, with fresh-repo mirror as last resort due to disruption of public link trail.
