+# E1A notify shadow 与切换
+
+## 目标
+
+notify 消费者具备 shadow 覆盖门、live 唯一可见结果与显式 rollback；生产集群保持 off。
+
+## 范围
+
+- Goose 00041、`EmitVisibleDocumentEvent`、`docnotify.EventConsumer`、Handler 与 Ack 同事务
+- cmd/events 注册 notify（mode=off 时不 claim）
+
+## 非目标
+
+- 不把共享环境 notify 切 live
+- 不删除 OnOutbox 闭包
+- 不激活 FAV / workflow advance / projection live
+
+## 步骤
+
+1. [x] 从 E0B 后 `dev` 开 `fix/event-notify-cutover`
+2. [x] additive `source_event_id` 与可见结果唯一索引
+3. [x] shadow dry-run + live 同事务 ack
+4. [x] fixture N=30、quarantine、correlation、rollback
+5. [x] 隔离库 PG + race + 报告
+
+## 验收标准
+
+- [x] [E1A 测试报告](../../test-reports/2026-09-15-event-e1a-notify-cutover-test-report.md)
+
+## 相关链接
+
+- Track E: [./2026-09-15-durable-event-track-e.md](./2026-09-15-durable-event-track-e.md)

+# E1A notify shadow/live/rollback 测试报告
+
+## 一、 测试背景 (Background)
+
+E0B 已交付独立 `cmd/events` 与原子 lease。本波把 `notify` 接到同一 Handler：副作用与 `AckLease` 同事务，用 `(source_event_id, user_id, type)` 保证重复投递只有一条可见通知。生产集群 mode 保持 **off**；闭包仍是当前唯一写者，直到显式 live 切换。
+
+## 二、 测试目标 (Test Objectives)
+
+- Goose 00041 additive：`notifications.source_event_id` + 部分唯一索引。
+- Shadow 对 Handler 做 dry-run（事务 Rollback），只写 `event_reconciliations.intended_digest`，不写 inbox、不 ack。
+- 规范化器比较收件人、类型、去重键 `evt:{eventID}:{type}:{user}`；live 指纹与 shadow intended 一致。
+- Fixture N=30（近 7 天文档事件流量为 0，沿用 E0A 低流量策略）。
+- 缺文档 → quarantine，无通知泄露；live 重放仍一条；mode=off 回滚不再 claim。
+- Handler+Ack 同事务：未提交的二次 Handle 回滚不增加行。
+- `off|shadow|live` 带 revision；FAV 仍 off。
+
+## 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-notify-cutover` |
+| Schema | **41** |
+| PostgreSQL | 隔离库 `agent_rel_e1a`（`shuimu-system-pg-test:5434`）；测完 DROP |
+| 项目 143 | 只读 |
+| 默认 mode | off（共享 `agent_system_dev` 未切 notify live） |
+| 证据 | `.doc/test-reports/assets/2026-09-15-event-e1a-notify-cutover/` |
+
+语义：至少一次投递 + 恰好一个可见结果。不是 exactly-once delivery。
+
+## 四、 预期结果 (Expected Results)
+
+| 用例 | 期望 |
+|------|------|
+| shadow | notifications=0；recon intended = `VisibleOutcomeDigest` |
+| live 两次 RunOnce | 同一 `(source_event_id, user_id, type)` 仅 1 行 |
+| live hash | 等于 shadow intended |
+| correlation | envelope → `event_delivery_attempts` → `notifications.source_event_id` |
+| fixture 30 | 30 条独立 approved fixture，shadow/live 各 30 |
+| 缺文档 | delivery=`quarantine`，通知=0 |
+| rollback tx | 已提交行仍为 1 |
+| mode=off | RunOnce claim=0 |
+| 共享库 mode | notify/projection/workflow_advance/fav 全 off |
+
+闭包 `OnOutbox` 不产生 `document.approved` 通知；approved 可见结果只走耐久 envelope。其它文档 outbox 类型仍由闭包写旧 `dedupe_key`，直到 E2 删除 hook。规范化比较用新 canonical key，不要求与闭包旧键逐字相等。
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 规范化器
+
+- **测试输入**: `unset TEST_DATABASE_URL; go test -short ./internal/app/docnotify -run TestIntendedNotifyDigestStable`
+- **实际输出**: PASS；`IntendedNotifyDigest` 与 `events.VisibleOutcomeDigest` 一致
+- **评价判定**: **PASS**
+- **性能与耗时**: <1ms
+
+### 5.2 隔离库 shadow → live → rollback
+
+- **测试输入**: `TEST_DATABASE_URL` → `127.0.0.1:5434/agent_rel_e1a`；`go test -v ./internal/app/docnotify -run 'TestE1A_|TestIntended'`
+- **实际输出**: 见 `assets/.../pg-test.txt`。goose 至 41；`TestE1A_NotifyShadowLiveRollback_PG` PASS（0.29s）；`TestE1A_NotifyFixtureThirtyAuthzAndRollbackTx_PG` PASS（0.06s）
+- **评价判定**: **PASS**
+- **性能与耗时**: 含 goose 0.36s
+
+### 5.3 race
+
+- **测试输入**: 同上隔离库；`go test -race ./internal/app/docnotify -run 'TestE1A_|TestIntended'`
+- **实际输出**: `assets/.../race.txt` PASS（1.14s）
+- **评价判定**: **PASS**
+- **性能与耗时**: 1.14s
+
+### 5.4 共享库默认 mode（只读）
+
+- **测试输入**: `SELECT environment, consumer, mode, revision FROM event_consumer_modes`
+- **实际输出**: 12 行均为 `off` / revision=1（`assets/.../consumer-modes.txt`）
+- **评价判定**: **PASS**（未对共享库 live claim）
+
+### 5.5 全仓 short / arch-check
+
+- **测试输入**: `unset TEST_DATABASE_URL; go test -short -count=1 ./...`；`./scripts/arch-check.sh --mode block`
+- **实际输出**: 全包 PASS；arch-check block PASS
+- **评价判定**: **PASS**
+- **性能与耗时**: 约 15s
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+| 命令 | 结果 |
+|------|------|
+| `go test -short ./...` | PASS |
+| `arch-check --mode block` | PASS |
+| 隔离库 `TestE1A_*` | PASS schema 41 |
+| `go test -race ./internal/app/docnotify` | PASS |
+| 生产 notify mode | **off**；闭包仍是 inbox 唯一写者 |
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+E1A **PASS**。兼容代码已注册 `ConsumerNotify`；集群开关仍 off。下一波 E1B：workflow advance shadow/live/rollback，并发批准只推进一次。不激活 FAV。不删除 `OnOutbox`（E2）。
