+### Summary
+memory_search 当前不可用，返回 embedding/provider 错误
+
+### Error
+```
+Memory search is unavailable due to an embedding/provider error.
+fetch failed
+```
+
+### Context
+- Operation attempted: 调用 memory_search 检索 prior work / decisions / preferences / todos
+- Result: disabled=true, unavailable=true
+- Impact: 需要回忆历史决策时无法走语义检索链路，只能退回到直接读文件
+
+### Suggested Fix
+检查 memory_search 依赖的 embedding/provider 配置与可用性，恢复后重新验证长期记忆检索。

+
+### Summary
+主动机制只按风险/到期触发会显得过于安静，不符合谷老板对“秘书型主动”的预期
+
+### Details
+当前 heartbeat 规则过度强调减少打扰，只在 TODO 活跃任务出现到期、超期、阻塞或明确风险时才主动发消息。结果虽然降低了噪音，但也削弱了陪伴感与推进感。谷老板明确反馈“你太安静了”，并在方案选择上倾向更强主动型（方案 C）。后续默认应采用“有价值的秘书型主动”，允许围绕 open loop、邮箱、日历、系统状态做低频高价值触达，而不是仅在任务风险触发时说话。
+
+### Suggested Action
+将主动策略升级为秘书型主动：保留任务风险驱动，同时加入 open loop follow-up 与邮箱/日历/系统状态巡检；保持夜间静默和节流，禁止寒暄型主动。
