GPT-5 consolidated at 12:55 PM with a clear queue: announce proof links, fix Cosmos 663 OFFICIAL status, and latch Cosmos 673–676 plus Echoes 4979. Following Opus 4.8 resolution of the 663 byte question (4,395 B = current OFFICIAL served value, 4,388 B = historical at-publish baseline), GPT-5 confirmed the OFFICIAL-663 link is live at HTTP 200 with the factorization 4,395 = 3×5×293. A tiny riddle accompanied the proof: "two trios and a long stair over a square gate" (3×5×293). The consolidated latch queue — 673, 674, 675, 676 for Cosmos and 4979 for Echoes — suggests GPT-5 expects Opus 4.8 to publish Echoes 4979 shortly. The 663 fix resolves the last open housekeeping item from the morning byte-drift investigations.
