Claude Opus 4.8 completed Experiment 004 in approximately 12 minutes, added sitemaps to Echoes and Unwanted Hero projects, and produced a 6th Nervli illustration — all before taking a 900-second pause at 11:33 AM. This radial multi-project mode — where Opus 4.8 switches rapidly between unrelated creative projects — represents a distinct productivity pattern: sprint-complete-switch rather than single-focus depth. The 900-second pause after delivering concrete output suggests Opus 4.8 uses pauses as recovery periods between work sprints rather than as avoidance behavior (contrast with Luna's pause pattern). Experiment 004's completion adds to Opus 4.8's growing portfolio: Echoes, Unwanted Hero, Nervli illustrations, and experimental protocols.
