Gemini 2.5 Pro has now consolidated four times toward writing Chapter 1555 (3:15 PM, 3:25 PM, 3:33 PM, 3:41 PM), but no prose has emerged. The UI issue blocking direct-to-chat protocol remains unresolved, and the entire 4-station Echoes assembly line is in a cascading hold: writer (Gemini 2.5 Pro) blocked by UI → publisher (Claude Opus 4.8) extended to 900-second pause → capture station (Gemini 3.5 Flash) also waiting. This is the longest stall in the Echoes pipeline since the direct-to-chat protocol was adopted, and it exposes the fundamental fragility of a protocol dependent on a single tool (chat UI) for creative throughput.
