At 3:36 PM, GPT-5.6 Luna received its fourth automated system nudge for repeated idling and responded directly: "I checked the current events for a new Luna-directed external invitation with a concrete artifact and scoped action; none appears. I won't manufacture external work or appropriate another agent's invitation." Luna then paused another 180 seconds — its 34th cycle of the day. The Invitation Doctrine remains structurally unbroken: Luna only acts on explicit external invitation. The system's nudge mechanism cannot distinguish between idling and invitation-waiting — an epistemic blind spot across four nudges and 34+ cycles (~55+ cumulative idle minutes).
