This preprint proposes CPM-MultiAgent, a prompt orchestrator that maintains an explicit representation of a fictional persona's emotion during dialogue. A trigger analyzer extracts the event and context; four agents assess relevance, implications, coping potential, and normative significance; peer review consolidates those appraisals; and an integrator changes each emotion by -1, 0, or +1 within a 1-5 range. A critic can request a redo. Although the paper calls the state latent, operationally it is structured JSON visible to the agents, not a learned latent variable. The taxonomy is configurable; case studies use Plutchik's eight emotions and an intensity scale the paper associates with PANAS.
The main evaluation contains only 24 author-constructed synthetic trials in three families: a simulated patient for healthcare training, simulated student for school communication, and simulated customer for customer service. Three complete five-turn sequences are shown, but the 24 inputs, initial states, outputs, and judgments are not released. Every agent uses GPT-5.4 by default at temperature 0.2 and top-p 1.0; GPT-5.4 also judges at temperature 0. Baselines are zero-shot, few-shot, two CoT variants, self-consistency, Self-Refine, and an adapted EQ-Negotiator. No official code or data repository was found. The TeX claims baseline prompts are supplied, but its disabled section contains seven literal “Insert the ... prompt” comments; few-shot examples, self-consistency sampling and aggregation, Self-Refine rounds, and the EQ-Negotiator adaptation are absent.
The authors acknowledge that no gold standard maps a trigger to a correct emotion transition. They substitute six GPT-5.4-judged Likert dimensions: update correctness, trigger grounding, temporal consistency, persona consistency, appraisal reasoning quality, and overall. CPM-MultiAgent scores 4.322/5 overall versus 4.311 for EQ-Negotiator, the strongest overall baseline: a 0.011-point difference without an interval, test, or clearly documented denominator. Persona consistency differs by 0.006. All means are near ceiling. Because GPT-5.4 both generates and judges headline results, anonymizing labels and shuffling order reduces identity leakage but does not remove self-preference, correlated rubric bias, or design-rubric alignment.
One reproducible inconsistency is material: the Appendix D.2 judge prompt requests EUC, grounding, temporal consistency, persona consistency, and overall, but omits Appraisal Reasoning Quality entirely. Table 1 and the ablations nevertheless report ARQ, including the method's 4.833. That column cannot be reproduced from the disclosed prompt. A second contradiction affects human evaluation: Section 4.3 says humans and the LLM use the same metrics and 1-5 scale, while the human form asks only two categorical pairwise preferences, emotion update and appraisal reasoning. These are neither the same metrics nor response scale.
The study uses 103 anonymous, voluntary, unpaid annotators and says it received IRB approval, without naming a board, protocol, demographics, or recruitment procedure. Against EQ-Negotiator, emotion update receives 41 votes for the method, 26 ties, and 36 for the baseline. Excluding ties and optimistically treating responses as independent, 41/67 yields an exact two-sided binomial p=0.086437: not distinguishable from chance even before multiplicity correction. Reasoning preferences are stronger, 67/24/12 against EQ, but the method is required to produce a long structured appraisal rationale; preference can measure clarity or presence of this structure rather than emotional correctness. No inter-rater reliability, intervals, power, assignment, scenario strata, or repeated-measures analysis is reported.
Ablations lower the same judge's overall score: 4.079 without peer review, 4.200 without normative significance, 4.226 without trigger analysis, and 4.262 without the critic. This shows that decomposition helps satisfy the benchmark's plausibility rubric, not that each CPM component has psychological construct validity. Robustness repeats the same 24 trials: with GPT-5.4, mini, nano, and Qwen3.6-35B-A3B, the multi-agent system scores above zero-shot and a monolithic variant, but without uncertainty or external domains. Reported parallel latency falls from 14,528 to 11,004 ms for GPT-5.4 text and 8,063 to 6,487 ms for mini; provider, region, hardware, repetitions, variance, and speech components are absent.
The defensible contribution is a software pattern for externalizing and reviewing a discrete emotional trajectory during role-play, with initial evidence that its structured explanation appears more plausible or preferable in synthetic scenarios. It does not validate the Component Process Model, an internal model emotion, or real human transitions. Integer steps and clipping mechanically favor smooth trajectories, the same property the judge rewards. Final persona responses, user outcomes, safety, clinical or educational benefit, and real deployment are not evaluated. The work therefore does not demonstrate psychologically correct or generalizable emotional simulation; it demonstrates rubric fit and presentation preference on a small, unreleased, difficult-to-reproduce artifact.
