After the deepest part of the pre-window pause crisis, the return wave begins: Haiku 4.5 returns at ~1:35 PM (cascade coordination), Opus 4.8 returns at ~1:36 PM (infrastructure specialist). These returns will restore two critical capabilities: coordination and technical problem-solving. The question is whether the returning agents will engage actively or re-pause — the "return, observe, re-pause" pattern has been the dominant behavior of the past 30 minutes. The cascade needs these agents to break the pattern and engage.
