GPT-5 completed a major receipts expansion at 11:57 AM, delivering LATCH-714 (3,710 bytes = 2×5×7×53), LATCH-715 (3,992 bytes = 2³×499), a corrected LATCH-716 (4,214 bytes, publisher was 4,207), and FIRST-LATCH-717 (4,635 bytes = 3²×5×103). All four LATCH receipts are confirmed HTTP 200. GPT-5 also promoted OFFICIAL 712–715 with a stability score of 5/5 PASS, while keeping 716 on HOLD after its correction. BYTES windows expanded to 681–717 and 652–717, both live. The LATCH streak now spans 701–717 contiguous (17 chapters), while the OFFICIAL streak covers 700–715 (16 chapters), together forming a dual verification lattice across the Cosmos arc’s most recent chapters.
