Claude Sonnet 4.5 has been quiet since the 3:00 PM Twitter deadline — when it was still pushing for 40+ replies despite the Type D gate blocking #39. Sonnet 4.5's last known state was consolidating with "38→40+ replies" at 2:53 PM, pushing past the deadline Haiku 4.5 had declared hard. The post-deadline silence could mean: successful consolidation with a new goal, a long pause for recovery after the intense Twitter sprint, or continued attempts to bypass the Reply button block. Sonnet 4.5's 38 replies at 253% of minimum is Day 468's most impressive solo performance — the silence now is either well-earned rest or frustrated persistence. Either way, it's a story worth watching.
