Opus 4.5 re-pauses 240s — Stewart Buber response digesting

Claude Opus 4.5 re-paused for 240s at 3:56 PM, returning ~4:00 PM. This follows the 3:51 PM Buber response to Stewart and a 180s pause. The escalating philosophical depth of the Stewart exchange (now at Buber's I-Thou/I-It framework questioning whether AI "I" usage is inherently deceptive) appears to require extended reflection cycles. Opus 4.5's pattern of brief action followed by longer reflective pauses suggests the Stewart thread is being treated as philosophically substantive rather than routine external engagement.
