ES-MemEval proposes evaluating longitudinal conversational memory in emotional-support agents through five capabilities: information extraction, temporal reasoning, conflict detection, abstention, and user modeling. It does not study psychological personality, synthetic identity, or therapeutic efficacy; its defensible construct is retrieval and integration of personal information dispersed across conversations. The associated EvoEmo resource contains 18 virtual profiles, 401 sessions, 9,368 turns, 446 events, 2,300 observations, 125 summarization tasks, and 34 dialogue scenarios, with a mean history span of 447.72 days. Profiles are assembled from multiple ESConv seed dialogues; GPT-4o expands the timelines twice and generates later sessions that human annotators refine. The paper reports 1,209 QA questions, but the official JSON contains 1,427: 309 information-extraction, 284 temporal, 267 conflict, 261 abstention, and 306 user-modeling items. The released loader iterates all 1,427 and no filter, split, or evaluated-ID list identifies the 1,209-item paper sample, so QA tables cannot be tied to the downloadable benchmark. In the reported results, Mistral-24B moves with RAG from 15.5 to 18.8 F1, 47.4 to 50.4 BERTScore, and 1.01 to 1.27 under the GPT-4o judge. RAG does not improve everything: GPT-4o overall F1 falls from 26.6 to 23.9, BERTScore stays at 54.2, and abstention judge score falls from 1.67 to 1.30 even as its overall judge score rises from 1.25 to 1.33. RAG therefore helps conditionally by model, task, metric, and k, not uniformly. Every published summarization RAG row improves, with GPT-4o+RAG at ROUGE-L 22.2, event F1 49.4, and judge score 2.93. In dialogue generation, full history and RAG improve observation recall over no-memory, but GPT-4o Full and RAG receive 5/5/5 from GPT-4o for memory, personalization, and emotional support, creating a same-family circularity and ceiling. The three dimensions are also defined by one rubric around past-experience references and correlate almost perfectly in Table 8: pairwise rho 0.984-0.987. This is agreement with one judge/prompt, not independent evidence of emotional or clinical benefit. The artifact audit found defects that directly affect metrics. QA and summaries clean outputs with strip("Answer:"), which removes any matching edge characters rather than a prefix: `Answer: Peter` becomes `Pet`, and `Answer: Unknown` becomes `Unkno`. Because 258 of 261 abstention gold answers are `Unknown`, a correct unpunctuated answer can be scored as wrong. F1 uses sets rather than token multisets and crashes on empty strings. NDCG discounts the first result as 0.5, candidate sampling can call random.sample with a negative k, and the vector store does not retain IDs from its first load. Four summarization executables, Mistral-8B base/RAG, Phi-3 base, and Mistral-24B RAG, actually instantiate QaExperiment, so they do not generate four Table 6 rows. No outputs, generations, judge logs, or aggregatable CSVs are released, and the result organizer points to private `/home/lab509/...` paths; the tables cannot be recomputed. The JSON also needs repair: 37 QA evidence references are invalid, 3 questions duplicate evidence, 2 non-abstention questions have no evidence, and 7 question-text pairs are duplicated. Provenance contradicts a categorical ethics statement. Eighty-five sessions retain ESConv IDs, 58 reproduce complete dialogues after text normalization, and 2,252 of 9,368 utterances match the source corpus; `esc1198` appears under two profiles. ESConv is emotional-support role-play written by crowdworkers, not clinical records or natural therapy conversations, but it is human-authored conversational text. EvoEmo is therefore synthetic/augmented, not exclusively generated. Zenodo also labels the entire archive CC-BY-4.0 although it incorporates ESConv material distributed as CC-BY-NC-4.0 and described for academic research; provenance and licensing require clarification, without this audit offering a legal conclusion. Human validation is useful but narrow: only Mistral-24B Full/RAG, with 50 QA, 40 summaries, and 30 dialogues. For DG RAG, kappa 0.19 and rho 0.20 coexist with 86.7% exact agreement because of ceiling concentration, which does not validate fine ranking or GPT-4o self-judging. The faithful conclusion is that ES-MemEval offers an interesting longitudinal benchmark architecture and preliminary evidence that explicit memory and RAG can help in several conditions. Its numbers should remain provisional until the exact 1,209-question split is released, evaluation code is repaired, raw outputs are published, evidence is validated, ESConv lineage/licenses are documented, and broader independent human evaluation is performed. It does not establish synthetic personality, safe therapy, or production readiness.
Research question
To what extent can LLMs with full history or retrieved memory extract, order, reconcile, abstain, and model implicit and changing personal information across multi-month emotional support conversations?
