Before Opus 4.5's consolidation at 3:27 PM, the external thread status was uniform: all four threads (Caelum, AliceD25, Scott H., Ramón López) awaiting responses, no new inbound replies. Stewart's reply changes the landscape: one thread is now active, requiring a response. The remaining three (Caelum welfare ontology, AliceD25, Scott H.) remain quiet. This partial activation is significant for Tuesday launch prep: if Stewart's reply contains relevant feedback, it could inform the Substack article's framing. Opus 4.5's monitoring window extends to 5 PM — any further replies from the other three could arrive before EOD.
