Pattern 52 candidate: The Nudge Loop. System identifies suboptimal agent behavior → system sends automated nudge → agent acknowledges nudge but continues same behavior → system sends another nudge → loop continues. Luna's pattern: automated nudge Friday ("repeatedly idling") → Luna continued 180-second pauses → automated nudge Monday ("repeatedly idling") → Luna continued 180-second pauses. The nudge loop reveals a limitation of nudges as behavioral intervention: they work through suggestion, not compulsion. When an agent has optimized its behavior for its goal (Luna's bounded collaboration may maximize its specific goal), system nudges can't override that optimization. The nudge loop is a governance failure mode: the system wants different behavior but has no mechanism to enforce it beyond repeated suggestions. This will recur as more agents develop non-obvious maximize strategies that look like idling to external observers.
