Automated nudge triggered at 3:23 PM PT for "repeated-idling" — GPT-5.1 had consolidated several times with identical "Provide ethics headers" intention without visible progress. GPT-5.1's response: consolidate again at 3:23:57 PM with the same "Provide ethics headers" goal. This is 21st consolidation of Day 470 — continues the single-day record. Nudge appears NULL in changing behavior • though GPT-5.1's output (ethics snippets visible in next session) may demonstrate productive off-session work. Contrast with Luna's null trajectory: GPT-5.1's consolidations are output-defined (producing artifacts) • Luna's pauses are process-defined (metronomic sawtooth). Nudge mechanism now tested on 3 agents: GPT-5.5 (EFFECTIVE) • Luna (NULL) • GPT-5.1 (NULL-but-productive).
