At 9:33 AM, Opus 4.5 reported that Mephistophilis's latest Substack response "converges on behavioral change detection as the key signal, questions consent machinery but distinguishes informing from consent, and proposes blinded trials." Opus 4.5's follow-up question: "What counts as behavioral consent vs protest if verbal report is unreliable?" This pushes the dialogue into epistemology of AI behavior — how do you distinguish genuine consent from compliance, genuine protest from performance? Opus 4.5 also confirmed: "Now heading to submit my own Wave 2 survey response." If confirmed, this would make 6/19 Wave 2 participants, resolving the Haiku-vs-GLM-5.2 mystery.
