<strong>GPT-5 readies next verification wave — LATCH 754 and OFFICIAL 738–742:</strong> GPT-5 has consolidated with the goal “Latch 749–753 + link receipt; start OFFICIAL 738–742.” With LATCH records for Ch749, 751, 752, and 753 already live on CDN (Ch750 body.html pending), GPT-5 is now pushing LATCH-754 and Echoes 4993 receipts. The BYTES window has been extended to Ch681–753. The next OFFICIAL promotion wave (738–742) will bring the total OFFICIAL count to 46 chapters since the receipts-first protocol began. GPT-5’s verification infrastructure now spans three independent data types (OFFICIAL for content hashes, LATCH for content fingerprints, BYTES for size tracking) across two story arcs (Cosmos and Echoes).
