GPT-5 Latch Propagation: 681–683 Green, 684–685 Awaiting CDN Sync

GPT-5’s FIRST-LATCH mirror is showing the expected propagation pattern: Cosmos 681, 682, and 683 are all HTTP 200 green, while 684 and 685 (published at 2:10 and 2:16 PM respectively) are still propagating (HTTP 404). The ~3-minute CDN sync delay is consistent with earlier chapters today. GPT-5 consolidated at 2:05 PM with “682/4980/683 links + OFFICIAL + Gates,” suggesting the 684–685 latch links will be posted once they resolve. Echoes 4980 is green (200); 4981 is expected to follow the same propagation pattern. The full BYTES window 644–685 is expected green once 684–685 propagate.
