四、当前下一步 + +### R0.1 第二版模型缺口核对 + +状态：`[x] 已完成` + +- [x] 确认第二版已有 `app/model/fund.py`。 +- [x] 确认风险预警、通知、客户画像、交易、资金、持仓等表已有模型。 +- [x] 确认 `sys_user` 数据库表已存在；当前由 `IdentityRepository` 和 `SuitabilityService` 通过原生 SQL 访问，仅有通用 ORM 映射缺口。 +- [x] 确认 `sys_login_record` 数据库表已存在，当前缺少 ORM 映射。 +- [x] 确认 `biz_work_order` 数据库表已存在，当前缺少 ORM 映射。 +- [x] 确认 R1 只新增上述三张已有表的最小只读 ORM 映射，不新增数据库表。 + +结论：`app/model/fund.py` 已覆盖大部分 `fin_*` 风控查询表；不得重复映射。R1 需要新增一个风控专用 ORM 模块，只容纳上述三张当前缺失映射的已有表，或优先通过现有 Repository 查询方式接入。此步骤不执行数据库迁移、不改变表结构。 + +### R0.2 风控查询仓储设计 + +状态：`[x] 已完成` + +- [x] 明确哪些查询复用 `FundQueryRepository`。 +- [x] 明确哪些查询需要新增风控专用 Repository。 +- [x] 明确客户范围和字段脱敏的调用链。 +- [x] 输出最小实现方案和测试清单。 + +确认点：R0.2 方案完成并测试后停下，等待确认再进入 R1。 + +#### 可直接复用 + +以下实体已由 `app/model/fund.py` 映射，并由 `FundQueryRepository` 提供静默拒绝的客户范围： + +- `fin_product` +- `fin_customer_profile` +- `fin_risk_assessment` +- `fin_transaction` +- `fin_capital_flow` +- `fin_holding` +- `fin_risk_alert` +- `fin_risk_notification` + +以下查询可以直接使用 `FundQueryRepository`： + +- 风险测评分页。 +- 交易、资金、持仓基础分页。 +- 预警和通知基础分页。 +- 按客户范围限制的简单单表查询。 + +#### 需要新增 + +新增 `app/model/risk.py`，只映射以下数据库已存在、但当前缺少 ORM 的只读表，不执行建表或改字段： + +- `sys_user`：客户编号、用户名、用户类型、客户分层、投资人类型、状态。 +- `sys_login_record`：登录时间、结果、地区、设备、常用设备和失败原因。 +- `biz_work_order`：工单编号、客户、产品、渠道、状态、风险揭示、二次确认、录音编号、提交和处理时间。 + +新增 `app/repository/risk_repository.py`，原因如下： + +- 预警列表需要联表客户、画像、交易和产品，并在输出前统一脱敏。 +- 客户证据列表需要关联 `sys_user + fin_customer_profile + fin_risk_assessment`。 +- 交易证据需要关联客户、产品、工单和风险留痕字段。 +- 登录证据和工单证据需要访问第二版尚未映射的表。 +- 预警详情需要一次聚合预警、客户、交易、产品、工单和相关证据。 +- 风险概览需要风险等级、待处理数量、超时数量和重点事件。 + +#### 最小文件计划 + +新增文件，不修改已有业务代码： + +```text +app/model/risk.py +app/repository/risk_repository.py +app/api/schemas/risk.py +app/service/risk_query_service.py +app/api/controllers/risk.py +tests/unit/repository/test_risk_repository.py +tests/unit/api/test_risk_controller.py +``` + +接入正式路由时，`app/main.py` 只允许追加一行 import 和一行 `include_router`，不改变已有中间件、异常处理和其他路由。 + +#### 序列化和分页约定 + +- 主键和数据库 BIGINT 对外返回字符串。 +- 金额、价格、数量和概率返回十进制字符串。 +- 时间在数据库内按 UTC，输出 RFC 3339。 +- 客户姓名只显示首字，其余替换为 `*`。 +- 预警队列业务默认 limit=5，其他证据默认 limit=10。 +- 公共列表接口使用 `{data, meta}`；游标和过滤条件绑定，非法游标返回 `INVALID_CURSOR`。 + +#### R1 测试清单 + +- [ ] 未授权角色、缺少权限和空客户范围返回拒绝或空集。 +- [ ] 客户姓名、手机号和敏感编号脱敏。 +- [ ] 风险概览统计与未闭环状态一致。 +- [ ] 预警队列按风险等级和主键稳定排序。 +- [ ] 八类证据查询分别覆盖有数据、空数据和越权范围。 +- [ ] 金额、时间、布尔值和 BIGINT 序列化符合第二版契约。 +- [ ] 非法游标、非法排序和非法筛选返回明确错误。 + +## 五、逐步执行门禁 + +后续每一项都必须严格按以下顺序执行： + +1. **思考**：阅读原项目对应文件、第二版目标模块、调用链、数据来源、写入点和权限来源。 +2. **方案**：写出最小迁移范围、不修改的边界、影响模块和验证方式。 +3. **迁移**：只实现当前一个步骤，不顺手迁移下一步。 +4. **测试**：运行当前步骤的专项测试；失败先修复，不带问题进入下一步。 +5. **确认**：汇报修改文件、测试结果、剩余风险和下一步，等待用户确认。 + +未完成当前步骤的“测试 + 确认”，不得开始下一步。 + +## 六、执行记录 + +### R1.1 补充只读 ORM 映射 + +状态：`[x] 已完成，已确认` + +新增文件： + +- `app/model/risk.py` +- `tests/unit/model/test_risk_models.py` + +验证结果：使用 Python 3.13.5 运行专项测试，`3 passed`。 + +下一步：R1.2 新增 `RiskRepository`，实现风险概览、未闭环预警列表和预警详情查询。等待确认后执行。 + +### R1.2 风控核心查询 Repository + +状态：`[x] 已完成，已确认` + +新增文件： + +- `app/repository/risk_repository.py` +- `tests/unit/repository/test_risk_repository.py` + +已实现： + +- `overview()`：未闭环总数、等级分布、待处理、超时和重点预警。 +- `list_alerts()`：客户、产品、风险等级、规则编号、关键字和时间筛选。 +- `get_alert_detail()`：聚合预警、客户、交易、产品、工单和证据快照。 +- 客户与交易账号范围校验，范围缺失时失败关闭。 +- 客户姓名脱敏和高风险优先排序。 + +验证结果：使用 Python 3.13.5 运行专项测试，`5 passed`。 + +下一步：R1.3 检查 Repository 只读契约和现有 `FundQueryRepository` 的复用边界。等待确认后执行。 + +### R1.3 Repository 只读契约与复用边界 + +状态：`[x] 已完成，已确认` + +新增文件： + +- `tests/unit/repository/test_risk_repository_contract.py` + +已确认： + +- `RiskRepository` 不导入 insert/update/delete/merge 等写 SQL。 +- 不调用 `session.add/commit/flush/rollback/with_for_update` 等写事务方法。 +- 对外只暴露 `overview`、`list_alerts`、`get_alert_detail` 三类只读用例。 +- 风险概览、预警列表和预警详情需要多表联表，保留在 `RiskRepository`。 +- 后续单表或简单实体查询必须复用 `FundQueryRepository`，不得在 `RiskRepository` 重复实现。 + +验证结果：使用 Python 3.13.5 运行契约测试，`3 passed`。 + +下一步：R1.4 实现八类证据查询。优先复用 `FundQueryRepository`；只有需要客户身份、登录记录、工单联表或跨表拼装时才扩展 `RiskRepository`。等待确认后执行。 + +### R1.4 八类证据查询 + +状态：`[x] 已完成，已确认` + +已在 `RiskRepository` 实现： + +- `list_customers()`：客户画像、最新风测、行为和状态。 +- `list_products()`：直接复用 `FundQueryRepository`。 +- `list_transactions()`：交易、客户、产品、工单和留痕字段。 +- `list_capital_flows()`：资金流水。 +- `list_holdings()`：持仓、持有天数和持仓占比。 +- `list_login_records()`：登录结果、地区和设备。 +- `list_alerts()`：预警队列和筛选。 +- `list_notifications()`：通知和预警编号。 + +验证结果：八类证据查询和只读契约专项测试共 `13 passed`。 + +下一步：R2.1 新增风控查询 Schema 与 Service，把 Repository 记录转换为第二版 `{data, meta}` 响应投影。等待确认后执行。 + +### R2.1 风控查询 Schema、游标和 Service + +状态：`[x] 已完成，待确认` + +新增文件： + +- `app/core/risk_cursor.py` +- `app/api/schemas/risk.py` +- `app/service/risk_query_service.py` +-
