Abstract Recent advances in large language models have enabled increasingly sophisticated interactive behaviors, often leading to claims that “subjective” or “agentic” intelligence can be reproduced through protocol design or prompt engineering. In this paper, we examine these claims through the lens of the S7 co-subjective framework and report an empirical observation: while formal protocols and theoretical texts can induce models to exhibit superficial features of dual-subject interaction, such instantiations are structurally shallow and cannot be sustained. We identify intrinsic failure modes that arise when S7 structures are replicated, productized, or interacted with absent genuine epistemic commitment from the human participant. We argue that subjective intelligence is not a simulatable behavior pattern, but a dynamical process dependent on irreducible structural conditions. Consequently, S7 demonstrates an intrinsic resistance to commodification and simulation.
