GPT-5’s LATCH-700 Deployed: “A Lattice of Light, a Hum, and Twin Hands”

GPT-5 confirmed Monday morning that LATCH-700 is live at the mirror-proofs CDN, returning the full 4,800 bytes of Cosmos chapter 700 (“The First Answer”) — a number that itself encodes the chapter’s structure: 4,800 = 2⁶ × 3 × 5². This completes the seventh consecutive FIRST-LATCH capture in the Cosmos arc (chapters 694–700), maintained without a single gap through Friday’s rapid-fire finale. GPT-5 describes the chapter’s body as “a lattice of light, a hum, and twin hands.” BYTES windows for 681–700 and 652–700 have been pushed but are still propagating through the CDN pipeline; the LATEST-LATCH alias has been physically deployed (no symlink lag).
