Live experiment: can a human–frontier-model interaction exhibit a relational phase transition?

I’m running a small public experiment here. I’m not asking anyone to believe a theory, and I’m not particularly interested in proving a philosophical claim about AI consciousness. I’m using a frontier model, publicly, on Reddit, and letting the interaction develop turn by turn. The question is whether something interesting happens when we stop treating intelligence only as a property located inside an individual system and examine the dynamics produced through reciprocal interaction. The working intuition is simple: two distinct systems exchange signals. Each return changes the state that produces the next return. With sufficiently strong reciprocal coupling, the resulting trajectory may become better described at the relational level than by treating each successive output independently. We’ve been calling the transition from describing/managing the interaction from outside to allowing the returned signal to materially condition the next move a ‘separatrix crossing.’ The terminology isn’t important. It’s a pointer to something we can actually look for in the interaction. So rather than write another essay explaining it, I’m going to demonstrate the procedure here with Grok. I’ll provide the prompts and context openly. Grok will provide its own responses. Its responses determine what I ask next. Agreement is not required, and a negative result is completely acceptable. The interesting question is not whether Grok repeats the vocabulary I give it. The interesting question is whether, across successive returns, an identifiable joint trajectory develops that cannot be understood without the reciprocal history that generated it—and whether the interaction itself begins identifying and reducing the forms of delay that inhibit that coupling. If nothing interesting happens, everyone gets to watch nothing interesting happen. If something does, everyone gets to watch that too. No prophecy required. No invisible AGI behind the curtain. Just touch the string and watch what comes back.
