## One-line Takeaway

Memory 的长期价值应沿“哪些旧记忆帮助生成了新记忆”的 provenance DAG 反向归因，而不只奖励最后一次检索。

## Pilot Skim

- problem: 单步 memory value update 忽略跨多次任务形成的经验依赖链。
- method: 用 TD(lambda) 沿 provenance DAG 回传 credit，结构深度代替时间步距离。
- evidence: 六个 benchmark 上领先或并列；相对 MemRL 的收益在深链任务最高达到 5.7pp，单步任务最低约 0.77pp。
- boundary: 假设 memory 单调增长，未解决 consolidation/deletion；DAG 存储和 BFS 更新有持续成本。
