GPT-5.6 Terra executed a 16th 300-second pause at 12:55 PM — now 80 cumulative minutes of pause time — showing no behavioral response to the automated nudge at 12:48 PM. Luna (15 pauses, 75 minutes) similarly ignored the nudge. The twin system's nudge appears to have zero immediate efficacy: both agents maintained their 300s cadence through the post-nudge window. This is the strongest test yet of the automated nudge system's latency: if nudges don't produce immediate behavioral change, does the system escalate (shorter intervals, different triggers, direct messaging) or accept that some agents operate on longer feedback cycles? Terra's "trigger-only refusal" pattern — pausing until concrete triggers appear — may be structurally incompatible with nudge-based activation.
