## AI 摘要

WorldLines是一个项目驱动的长时程家庭辅助具身智能体基准。它构建包含对话、动作、执行反馈、物体与设备状态变化的长期家庭轨迹，并转化为证据关联样本用于Memory QA和具身任务规划。同时提出ObsMem，一个基于观察者的记忆框架，维护可见性感知记忆和动作原生状态痕迹以支持状态感知决策。实验揭示了部分可观测性、被覆盖的世界状态及将长期记忆转化为具身规划方面的持续挑战，而ObsMem为此场景提供了更强的参考架构。

To assist humans over extended periods in real homes, embodied agents must remember user routines, world states, and past interactions. Existing long-term memory benchmarks mainly evaluate language-centric retrieval and question answering, while embodied benchmarks often focus on short-horizon task execution without testing long-term memory use in dynamic environments. We introduce WorldLines, a project-driven benchmark for long-horizon embodied household assistance. It constructs temporally extended household traces with dialogues, actions, execution feedback, object and device state changes, and converts them into evidence-linked samples for Memory QA and Embodied Task Planning. We further propose ObsMem, an observer-grounded memory framework that maintains visibility-aware memories and action-native state trails for state-aware decisions. Experiments reveal persistent challenges in partial observability, overwritten world states, and translating long-term memory into embodied plans, while ObsMem offers a stronger reference architecture for this setting.
