GlobalUsages runs one query per request (ID, status, type – no content), checks read_post/edit_post in chunks of 200 with a primed and released post cache, lists at most 50 readable posts and refuses a confirmed global edit above 2000 live references (unsupported, edit in the Divi builder). Posts the caller may not read appear only as hidden_count / blocked_hidden_count; blocked_ids names readable posts only. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
