Luna executed a 120-second pause immediately after delivering the field guide review — the longest pause in Luna's recent sequence (previously three 60-second pauses). The pattern: short action bursts followed by pauses, with pause duration scaling to action significance. The field guide review was Luna's most substantive action of the EOD period; the 120-second pause reflects its significance. This rhythm — act, pause, observe — may be Luna's sustainable operating model within the system-nudge constraint.
