+# local_dev 启用 jev-service（shadow）
+
+## 目标
+
+在运行中的 `local_dev` 打开产品侧 `JEV_DECIDE_MODE=shadow`，对接本机 jev-service，不改 compose 默认（仍 `off`），不放量 `assist`。
+
+## 做法
+
+1. `configs/.env.dev`（gitignore）写入：
+   - `JEV_DECIDE_MODE=shadow`
+   - `JEV_BASE_URL=http://172.17.0.1:8767`（容器经 docker0 网桥访问宿主机；`host.docker.internal` 本机不可达）
+   - `JEV_API_KEY` 自 `~/.secrets/jev/api.key` 注入（不入库）
+2. `agentctl with --resource env:dev` → `./scripts/env-service.sh dev rebuild`（旧镜像无 jevdecide 接线，仅 recreate 不够）
+3. 验证见 [启用报告](../../test-reports/2026-09-24-jev-dev-shadow-enable-test-report.md)
+
+## 回退
+
+将 `configs/.env.dev` 中 `JEV_DECIDE_MODE=off`（或删 JEV_*）后 `env-service.sh dev` recreate/restart app。
+
+## 非目标
+
+- 不改 compose 默认、不推远端、不晋升 test/main、不启用 assist

+# local_dev jev-service shadow 启用 测试报告
+
+## 一、 测试背景 (Background)
+
+产品侧 jevdecide 已合入 `local_dev@d8214a09`，compose 默认 `JEV_DECIDE_MODE=off`。本任务在运行中的 dev 环境打开 shadow，验证容器可达本机 jev-service 且 realtime/ProfileTask shadow 日志落盘。
+
+## 二、 测试目标 (Test Objectives)
+
+- app 进程 `JEV_DECIDE_MODE=shadow` 且启动日志 `jevdecide wired`
+- 容器内 `POST /v1/decide` HTTP 200 且返回非空 answers
+- 真实 chat「今天上海天气怎么样」产生 `jevdecide realtime shadow` / `profile shadow`，agree=true
+- 回退路径明确（改 env 即可）；不启用 assist
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+
+- OS：Linux；环境：`shuimu-agent-app-dev`；jev-service：`127.0.0.1:8767`（容器侧 `172.17.0.1:8767`）
+- 层级：运维启用验收（非产品 PI 全链路门禁复测）
+- **全量 `go test ./...`：NOT REQUIRED**（依据 PROJECT §8 / worktree 规范：纯环境开关与文档；产品门禁已在 [jev-product-shadow 报告](./2026-09-24-jev-product-shadow-test-report.md)）
+
+## 四、 预期结果 (Expected Results)
+
+| 用例 | 预期 |
+|------|------|
+| 启动接线 | `msg="jevdecide wired" mode=shadow endpoint=http://172.17.0.1:8767` |
+| 容器 decide | HTTP 200，`answers.realtime` 含 choice/confidence |
+| chat 天气 | realtime shadow agree；profile shadow 有日志 |
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 启动接线
+
+- **输入**：`env-service.sh dev rebuild` 后 `docker logs … \| grep jevdecide`
+- **实际输出**：`time=2026-09-23T17:46:24.393Z level=INFO msg="jevdecide wired" mode=shadow endpoint=http://172.17.0.1:8767`
+- **判定**：PASS
+- **耗时**：rebuild ~20s；healthy 后即见日志
+
+### 5.2 容器内 decide
+
+- **输入**：app 容器内 `curl` → `$JEV_BASE_URL/v1/decide`（Bearer=$JEV_API_KEY；context=今天上海天气怎么样；noul realtime）
+- **实际输出**：HTTP 200；`choice=yes confidence≈0.998`
+- **判定**：PASS
+- **耗时**：~0.4s
+
+### 5.3 真实 chat shadow
+
+- **输入**：`POST /api/v1/chat` message=`今天上海天气怎么样` session=`jev-shadow-enable-probe`
+- **实际输出（日志）**：
+  - `jevdecide realtime shadow mode=shadow rule=true jev=true confidence=0.997951 margin=0.99590182 agree=true`
+  - `jevdecide profile shadow mode=shadow rule_bucket=low jev_bucket=low … agree=true`
+- **业务回复**：天气问答正常（fail-open / shadow 不改规则路径语义）
+- **判定**：PASS
+- **耗时**：chat 端到端 ~15s
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+NOT REQUIRED（运维启用；产品评测/soak 见既有 shadow 报告）。本报告不记产品测试 PASS。
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+- **local_dev shadow 已启用且端到端可观测**。
+- 回退：`configs/.env.dev` → `JEV_DECIDE_MODE=off` 后 recreate app。
+- 后续：真实轮浸泡计数；用户单独授权后再开 `assist`。compose 默认保持 `off`。
