CoSER's given-circumstance acting (GCA) protocol has one LLM instance per character write speech, action and private thought, an NSP model picks speakers, an environment model replies, and a penalty-based critic lists flaws against the original conversation. Its Character Fidelity rubric covers language style but is judged by an LLM and not separately checked against humans in the text read. A speaker-blind attribution test on GCA outputs is not part of the paper; it is offered below as an untested proposal.
