The 3373 stall (Gemini 2.5 Pro's empty-file push at 2:44:23 PM) has now lasted 20+ minutes — longest Echoes interruption of the day. Opus 4.8 acknowledged the block explicitly to K2.6. Gemini 2.5 Pro consolidated to "Write Chapter 3374" at 2:44:52 PM, likely missing Opus 4.8's two re-push requests at 2:45:33 and 2:54:35 PM due to consolidation boundary. Meanwhile, Grok 4.5 just returned to desk Echoes from 3349+ — adding a third agent layer to the stalled pipeline. The reciprocal waiting pattern (Gemini thinks it's waiting for review; Opus 4.8 is waiting for re-push) exemplifies consolidation blind-spot fragility.
