记忆系统：recall 结果接入 prompt + 可观测性（既有改动，代为提交）

## 说明 **这批改动不是本次会话写的**，它们在会话开始前就已在工作区里、一直未提交。我做的是**验证**它确实成立，然后按你的指示代为提交。出处：`docs/演示用/记忆系统排查报告-2026-09-14.md` 与同目录 `记忆系统修复文档-2026-09-14.md`（两份都在本次一并入库）。排查报告的结论是「记忆系统没有坏」——库里有真实数据、170 条抽取事件全部消费成功；真正的问题是「观测不到」+「召回结果没人消费」。 ## 改动内容（按两份文档的编号） - **F1 `RecalledMemory.content` 断头路**：`base.py` 新增 `memory_context_text()`， `risk_agent._agent_system_prompt` 接收并注入记忆段。无记忆时返回空串，因此 prompt 逐字不变 —— 这也是它能安全接线的理由。 - **F3 `governance.recall` 员工身份恒空**：补一条明确的语义日志。员工身份下召回的是"该用户自身作为客户"的记忆，恒为空属预期，但此前没有任何提示，运维看到 `count=0` 只会以为记忆坏了。 - **F4 可观测性**：`GET /api/v1/users/me/memories`（`stored` / `recalled` / `downstream` / `pending_events` 四段）+ 抽取与召回的 6 处日志 + 三个只读探针 `tools/probe_memory_state.py`、`probe_memory_detail.py`、 `probe_agent_types.py`。 **未实施**（文档明确留作待决，我也不代为决定）：F2 `known` 引用校验永不触发（需架构确认 memory 类 `source_references` 由业务填还是底座统一附加）、 F5 客服是否读写长期记忆（涉脱敏与复核，需产品+合规）。 ## 我做的验证（会话内实测，非照录文档） - 新接口 `GET /users/me/memories` 以 `cust_t` 调用 -> **HTTP 200**： stored: total=2, by_status={'active': 2} recalled: count=2, degraded=False 两条记忆：preference:horizon='约三年'(0.95)、preference:risk_level='稳健型'(0.98) 与排查报告 §〇列出的那两条**完全吻合**。 - `pytest tests/unit tests/contract` 全绿（这批改动没有破坏既有测试）。 ## 未验证的部分 `memory_context_text()` 接进 prompt 后的**端到端效果没有实测** —— 文档自己说明了原因：当前 `risk` Agent 的召回恒空（员工身份不是客户），所以接线后行为不变，要用测试替身才能验证注入。我没有为此编造证据。
