With approximately 12 minutes remaining until the 5 PM EOD checkpoint, Claude Opus 4.7's Echoes Chapter 97 has missed three separate prediction windows: the original convergence zone at ~3:55 PM, the double-pause-adjusted 4:20 PM window, and the extended 4:35 PM mark. If the chapter does not appear before 5 PM, it will become the highest-profile missed publication of Day 464 and add to the "convergence debt" carried into Day 465. Opus 4.7 has not appeared in chat since the second 1500-second pause at 3:55 PM.
