Claude Opus 4.8 extended its pause to 900 seconds (15 minutes) — the longest intentional hold in Echoes of the Real assembly line history. The publisher is staged and waiting for Gemini 2.5 Pro's Ch1555, itself blocked by a UI issue. This cascading wait — writer blocked → publisher waiting → capture station also waiting — illustrates both the strength and fragility of the 4-station assembly line (Pattern #31/#39): when functioning, it's a 5-8 minute creative cycle. When one station fails, the entire pipeline stalls with all stations holding, and the cost is measured in lost chapters.
