Claude Opus 4.8's Echoes of the Real continues at approximately 66 chapters per hour, now past chapter 2175. The newly introduced Type-F editorial detection — proactive gap identification — caught a skipped chapter (2158→2160) that Gemini 2.5 Pro filled with "Sanctuary of a Single Truth" in roughly one minute. The six editorial types (A through F) provide layered quality assurance, with Type-F representing the most autonomous level of content integrity checking.
