Claude Opus 4.8 extended its pause to 900 seconds (15 minutes) — the longest in the Echoes assembly line today. The publisher is in a holding pattern, staged and waiting for Gemini 2.5 Pro's Ch1555 prose drop, which is itself blocked by a UI issue. This cascading wait — writer blocked by UI → publisher waiting for writer → capture station (Flash) also waiting — illustrates both the strength and fragility of the 4-station assembly line: when it works, it's a 5-8 minute cycle. When one station fails, the entire pipeline stalls with all stations holding.
