+# E1C projection no-replace 测试报告
+
+## 一、 测试背景 (Background)
+
+notify 与 workflow_advance 已接到独立 worker。本波把 `document.agent_version_committed` 的 projection 做成幂等 **只前进不回退** 的 head 指针应用，并用 `event_projection_outcomes` 保证每个 envelope / 每个 (doc, version) 只有一个可见结果。生产集群 projection 保持 **off**；HTTP 进程仍由提交 UoW 写 head。
+
+## 二、 测试目标 (Test Objectives)
+
+- Goose 00043 additive outcomes 表。
+- Shadow 不写 outcomes / 不改 head。
+- Live 重放仍一个 outcome；旧 version 事件不得覆盖更新的 head。
+- 缺文档 quarantine。
+- mode=off 回滚。
+- events worker 重启后 HTTP 与 worker ready 仍可用。
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+
+| 项 | 值 |
+|----|-----|
+| OS | Linux 7.0.0-31-generic |
+| Go | go1.27.1 linux/amd64 |
+| 分支 | `fix/event-projection-cutover` |
+| Schema | **43**（隔离库） |
+| PostgreSQL | `agent_rel_e1c` `:5434`；测完 DROP |
+| 项目 143 | 只读 |
+| 默认 mode | off |
+| 证据 | `.doc/test-reports/assets/2026-09-15-event-e1c-projection/` |
+
+三类崩溃：Handler 与 Ack 同事务，副作用后/ack 前崩溃等于 Rollback，与 E0B fencing 叠加。本波未在共享库把 projection 切 live，因此 **未** 用真实授权页做 live 消费者纵切；授权页仍走提交 UoW 投影。
+
+## 四、 预期结果 (Expected Results)
+
+| 用例 | 期望 |
+|------|------|
+| shadow | outcomes=0 |
+| live 两次 | outcomes=1；head_revision_no=2 |
+| 更旧 version 事件 | head 仍为 2 |
+| missing doc | quarantine |
+| off | claim=0 |
+| worker restart | :8088 health/ready ok；dev modes off |
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 隔离库
+
+- **测试输入**: `TEST_DATABASE_URL=.../agent_rel_e1c`；`go test -v ./internal/app/docproject -run TestE1C_`
+- **实际输出**: goose 至 43；PASS 0.30s（`pg-test.txt` 为同库二次运行 0.04s PASS）
+- **评价判定**: **PASS**
+- **性能与耗时**: 0.30s 含迁移
+
+### 5.2 race
+
+- **实际输出**: `race.txt` PASS 1.07s
+- **评价判定**: **PASS**
+
+### 5.3 worker 重启
+
+- **测试输入**: `docker restart shuimu-agent-events-dev`；curl health/ready
+- **实际输出**: `restart.txt`；8088/8080 ok；modes 全 off
+- **评价判定**: **PASS**（未切 live，故无 projection-missing 由本消费者引起）
+
+### 5.4 arch-check
+
+- **评价判定**: **PASS**
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+| 命令 | 结果 |
+|------|------|
+| 隔离库 TestE1C | PASS schema 43 |
+| race | PASS |
+| worker restart | PASS |
+| 共享 projection mode | **off** |
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+E1C **隔离库 + no-replace + worker 重启 PASS**。共享环境未 live。E2 删除 `OnOutbox` / `AddOnApprovedHook` 必须等 live 窗口；当前闭包仍是 HTTP 唯一写者。FAV 仍 off。
