Subject: [PATCH 1/6] fix(docgov): map zero duty ids to NULL on
 CreateOrGetDocument

Optional reviewer/approver duties leave UserID=0; writing 0 into
document_records FK columns failed with SQLSTATE 23503. Align create
path with docduty nullIfZero and surface ensureUser failures in logs.

+# 可选职责空审核人 CreateOrGetDocument 写 reviewer_id=0 触发 FK
+
+## 现象
+
+dev 项目「内廷元无创神经刺激器」(6417) 发起 `intake` 任务后 UI 显示：
+
+- `code: INTERNAL_ERROR`
+- `userMessage: 系统内部错误，请重新开始会话`
+- `requestId: run_1789622069585300787`
+- `sessionId: sess-p6417-u9`
+
+浏览器偶发 `flushSync was called from inside a lifecycle method`（错误态重渲染副作用，非根因）。
+
+## 根因分析
+
+1. app-dev 日志：`persist document ledger: ... document_records_reviewer_id_fkey (SQLSTATE 23503)`
+2. 项目成员仅 `document_duty=author`（user 9），无 reviewer/approver
+3. `resolveTaskDocumentDuties` 合法返回 `ReviewerID=0`
+4. [`internal/docgov/engine.go`](../../internal/docgov/engine.go) `CreateOrGetDocument` 把 `0` 写入可空 FK，PG 拒绝（无 `users.id=0`）
+5. `ClassifyError` 默认分支掩盖为 `INTERNAL_ERROR`
+
+对照：[`internal/docduty/store.go`](../../internal/docduty/store.go) heal 路径已有 `nullIfZero`，**创建路径漏改**。
+
+复现：`INSERT ... reviewer_id=0` → 同 FK 错误。近 7 天同因至少 3 次（6417/6359/6274）。
+
+## 严重度
+
+`high`（任何无 reviewer 职责的项目首次落文档账本均会失败；可扩散至 test/main）
+
+## 关联整改
+

+- Fix branch: `fix/docgov-optional-duty-null-fk`
+
+## 证据
+
+- `docker logs shuimu-agent-app-dev` @ `2026-09-17T05:14:29Z` run_1789622069585300787
+- `task_runs.error_message` 与上述一致；`document_records` 对 project 6417 为 0 行
+- 手工 `INSERT reviewer_id=0` → `Key (reviewer_id)=(0) is not present in table "users"`
+
+## 后续
+
+- 创建路径 0→NULL；ClassifyError 增加 `DOC_LEDGER_ERROR`
+- 不强制配置 reviewer（保持可选职责语义）
+- flushSync 另开任务

+# 修复 CreateOrGetDocument 可选职责 0→NULL FK
+
+## 目标
+
+无 reviewer/approver 职责时创建文档账本成功，不再因 `reviewer_id=0` FK 失败并被标成 `INTERNAL_ERROR`。
+
+## 范围
+
+- `internal/docgov/engine.go`：`nullIfZero` 写入 author/reviewer/approver
+- `internal/stream/classify.go`：`DOC_LEDGER_ERROR` 分型
+- 回归测试 + audit/test-report
+
+## 非目标
+
+- 不强制项目配置 reviewer
+- 不改前端 flushSync / 虚拟列表
+- 不改项目 6417 存量数据（代码修好后重试即可）
+
+## 步骤
+
+1. [x] CreateOrGetDocument 0→NULL
+2. [x] ClassifyError `DOC_LEDGER_ERROR`
+3. [x] 单元/回归测试（`-short` 已绿）
+4. [ ] 占集成槽位 rebuild + 6417 或等价复测
+5. [ ] test-report 归档；合入 `dev`
+
+## 验收标准
+
+- [ ] `go test -short ./internal/docgov/... ./internal/stream/...` PASS
+- [ ] 仅-author 项目 `CreateOrGetDocument` / 任务发起不再 `INTERNAL_ERROR`；`reviewer_id IS NULL`
+- [ ] full 职责项目仍写入非空 reviewer/approver

+# CreateOrGetDocument 可选职责 0→NULL FK 测试报告
+
+## 一、 测试背景 (Background)
+
+dev 项目「内廷元无创神经刺激器」(6417) 发起 `intake` 任务时，UI 报 `INTERNAL_ERROR` /「系统内部错误，请重新开始会话」（`run_1789622069585300787`）。根因是可选审核职责为空时 `CreateOrGetDocument` 写入 `reviewer_id=0`，触发 `document_records_reviewer_id_fkey`，再被 `ClassifyError` 兜底掩盖。
+
+## 二、 测试目标 (Test Objectives)
+
+- 仅-author 项目创建文档账本成功，`reviewer_id`/`approver_id` 为 SQL NULL
+- 不再出现 `persist document ledger` / `INTERNAL_ERROR`（该路径）
+- ledger/FK 残差错误分型为 `DOC_LEDGER_ERROR`
+- 单元与 `-short` 回归通过
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+
+| 项 | 值 |
+|---|---|
+| OS | Linux |
+| 分支合入 | `dev` @ `merge: fix/docgov-optional-duty-null-fk` |
+| 环境 | agent-dev `:8080`，schema 48，真实 PI |
+| 层级 | 单元 / DB 集成 / 真实 task run 冒烟 |
+
+## 四、 预期结果 (Expected Results)
+
+1. `nullIfZero(0)==nil`；`CreateOrGetDocument(..., reviewer=0, approver=0)` 成功且 DB NULL
+2. `ClassifyError(persist document ledger ... 23503)` → `DOC_LEDGER_ERROR`
+3. 项目 6417 重试 `intake`：越过账本创建；`doc_proj6417_intake` 存在且 `rev_null/app_null=true`
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 用例 1：单元 / short
+
+- **输入**: `go test -short ./internal/docgov/... ./internal/stream/...`
+- **实际输出**: `ok`（含 `TestNullIfZero`、`TestClassifyError_DocumentLedgerFKIsLedgerError`）
+- **判定**: PASS
+- **耗时**: ~0.5s
+
+### 用例 2：DB 集成 OptionalDutiesNullFK
+
+- **输入**: `go test ./internal/docgov/ -run OptionalDutiesNullFK -count=1`
+- **实际输出**: `--- PASS: TestDocGov_CreateOrGetDocument_OptionalDutiesNullFK`
+- **判定**: PASS
+
+### 用例 3：dev 真实任务（项目 6417）
+
+- **输入**: admin 登录后 `POST /api/v1/tasks/runs`（`task_key=intake`，`session_id=sess-p6417-u9`，`project_id=6417`）
+- **实际输出**:
+  - 创建响应：`{"run_id":"run_1789625396102207018","status":"running"}`
+  - DB：`doc_proj6417_intake | author_id=9 | rev_null=t | app_null=t | drafting`
+  - 未再出现 `persist document ledger` / `document_records_reviewer_id_fkey`
+- **判定**: PASS（账本 FK 根因已消除；任务可继续进入 PI 执行阶段）
+- **耗时**: 账本落盘在秒级完成（对比失败 run 立即 failed）
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+```text
+go vet ./internal/docgov/... ./internal/stream/...
+go test -short ./internal/docgov/... ./internal/stream/...
+# ok docgov / stream
+./scripts/env-service.sh dev rebuild
+curl -sf http://127.0.0.1:8080/health  # ok, schema_version=48
+```
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+- **结论**: 达到合入与冒烟标准；可选职责空审核人不再因 FK=0 导致 `INTERNAL_ERROR`。
+- **后续**: 前端 `flushSync` 警告另开任务；全链路 PI 完成质量属独立验收，不阻塞本修复。
