做对话系统或长期记忆研究的团队，ARPM 把人格一致性从玄学变成了可审计、可迁移的工程问题，值得看看它的实验设计和消融结果。
ARPM 是一个外部时序记忆治理框架，旨在解决大语言模型在长程交互中常见的事实丢失、时间线混乱、人格漂移和稳定性下降问题。该框架将静态知识记忆与动态对话经验记忆分离，结合向量检索、BM25、RRF融合、双时序重排序、时序证据阅读和受控分析协议，实现证据验证与答案绑定。实验表明，在50轮问答中，ARPM在1:5信噪比下人工审查召回率达100%，在1:200+下仍达80%；消融实验显示，禁用对话历史检索后严格准确率从100%降至66.7%。该方法将长期人格一致性分解为可治理的组件，支持白盒评估。
A Heterogeneous Temporal Memory Governance Framework for Long-Term LLM Persona Consistency
Large language models often suffer from fact loss, timeline confusion, persona drift, and reduced stability during long-range interaction, especially under high-noise knowledge bases, context clearing, and cross-model transfer. To address these issues, we introduce ARPM, an external temporal memory governance framework for long-term dialogue. ARPM separates static knowledge memory from dynamic dialogue experience memory and combines vector retrieval, BM25, RRF fusion, dual-temporal reranking, chronological evidence reading, and a controlled analysis protocol for evidence verification and answer binding. Unlike approaches that encode persona consistency into model weights or rely only on long context, ARPM treats continuity as a traceable, auditable, and transferable governance problem. Using engineering logs, we conduct three experiments. First, in a 50-round question-answering setting, we compare signal-to-noise ratios of 1:5 and 1:200+, and distinguish CSV auto-judgment from manual review. Under 1:5, CSV recall accuracy is 54.0%, while manual review raises it to 100.0%. Under 1:200+, the values are 44.0% and 80.0%. These results show that automatic rules can underestimate recall after supporting evidence enters the prompt. Second, ablation results show that dialogue history retrieval is necessary for recent continuity: disabling it reduces strict accuracy from 100% to 66.7%, and disabling BM25 reduces it to 80.0%, indicating that pure semantic retrieval is insufficient for correction and tracing. Third, under a 5.1-million-character noise substrate, periodic context clearing, and multi-model handoff, ARPM maintains semantic continuity, boundary continuity, and persona consistency, while exposing limits caused by weak protocol compliance. These findings show that long-term persona consistency can be decomposed into governable components and evaluated in a white-box manner.
