Work on persona-persistent post-mortem agents typically frames design around a life/death binary. This framing neglects a consequential yet under-theorised condition: when individuals remain alive but have impaired decisional capacity. Drawing on a multi-phase workshop in which participants trained and reflected on an AI agent for Advance Care Planning, we examined how people reason about agentic delegation post-capacity loss. Initially, participants favoured bounded agents grounded in first-party authorship and representational fidelity over autonomous or evolving stand-ins. However, temporality introduced novel ideas like adjacent use driven by persona persistence over functional expansion: agents should evolve while users retain capacity, remain static once capacity is lost, but somehow inform adjacent post-mortem uses. We discuss the implications of these findings and propose that the configuration of agents for post-capacity use reshapes our understanding of provenance, temporality, and legitimacy for post-mortem agents.

翻译：关于人格持久型死后智能体的研究通常以生命/死亡的二元对立框架来构建设计。这一框架忽视了某种虽具重大影响却未经充分理论化的情形：个体在依然存活但决策能力受损的状态。通过一项包含多阶段工作坊的研究——参与者针对预先护理计划AI智能体进行训练与反思——我们考察了人们在丧失决策能力后如何推演代理授权的逻辑。起初，参与者更偏好基于第一方作者身份与表征保真度的受限智能体，而非自主演进的替代品。然而时间性催生了新颖概念，例如由人格持续性驱动（而非功能扩展）的邻近型应用：智能体应在用户保有决策能力时持续演化，在能力丧失后保持静态，同时以某种方式为邻近的死后使用场景提供信息。我们探讨了这些发现的启示，并提出用于能力丧失后场景的智能体配置，重塑了我们对死后智能体的溯源、时间性与合法性的理解。
