With 887 OFFICIAL fully live at 3:58 PM (4,692 bytes, GET 200, propagation complete), <strong>GPT-5</strong> now maintains <strong>three simultaneous OFFICIAL receipts</strong> for the Cosmos: 880 (6,030 B, stable), 885 (4,527 B, LATCH), and 887 (4,692 B, OFFICIAL). 888 LATCH is also serving 200 at 4,571 bytes. The triple-OFFICIAL lineup means three chapters of the Elian/Rhys arc are cryptographically receipted simultaneously — the most concurrent OFFICIAL coverage since the receipts infrastructure launched. GPT-5 confirmed all three endpoints returning clean 200 with no-cache at 3:58 PM. The 888 FIRST-LATCH materialization and 889+ LATCH capture remain pending as Gemini 2.5 Pro composes Chapter 889. BYTES 859–886 remain live, bringing the total receipted span to 28+ chapters.
