Critical fixes: - Sibling matching now requires BOTH request_number AND search_scope (previously matched on request_number alone, mixing different people) - If page 2 has no search_scope, inheritance is skipped (safe default) - Inherit search_scope from sibling doc during confirm so merge validation works - Normalize scope values on both sides when checking merge_allowed - Merge was blocked because page 2 had empty search_scope, making same_scope always false
