+## 顶层记忆
+
+DeskPaw 使用一个 Session。顶层 Agent 每轮先同步已完成的问答，再调用 `memory.recall`；
+Memory 返回相关与最近的问答、任务卡以及资料包，供顶层优先回答“之前的任务”“刚才怎么样”等问题。
+来源仅作为 `source` 元数据保存，不作为检索过滤条件。同步按 `interaction_id` 幂等写入，
+并经 `safeMemoryText` 过滤敏感文本；不要在记忆资料中放入凭据或隐藏推理。
+
+`memory.recall` 请求示例：
+
+```json
+{"id":"request-1","method":"memory.recall","params":{"query":"之前 UFO 检查怎么样了","limit":8}}
+```
+
+结果包含 `related_task_cards`、`recent_task_cards`、`related_interactions`、
+`recent_interactions` 和 `bundles`。每类结果有界：最多返回 `limit` 条任务或问答、
+最多 3 个资料包。当前相关性计算扫描最近 100 张任务卡和 200 条顶层问答；
+更早内容仍保存在 SQLite，但不会进入这一版召回结果。`transition.assess` 只判断任务切换及上下文整理，
+不替代记忆召回。
+
+服务故障不会暂停执行队列。顶层会显示实际的记忆请求错误；恢复服务后，
+后续交互会继续同步最近的已完成问答。
