 ## 与仓库级文档的关系
 
 - 全仓约定、走查、接口不变等说明见仓库根下 **`../../../docs/`**（相对本文件）。
+- 发布包与**历史 JAR 接口对拍**（计划/报告）见聚合工程目录 **`../../docs/elevator-api-parity/PLAN.md`**、脚本 `../../scripts/run_elevator_parity.sh`。
 - 本目录专注 **本 service 模块内** 类职责与业务流程梳理，不替代对外 API 合同文档。

+# 新旧版本发布包：接口同构验证计划
+
+## 1. 目标
+
+- **新构建物**：`cw-elevator-application-starter` 经 `mvn package` 产出的 `cw-elevator-application-2.0.0.jar`。
+- **历史基线**（约定路径，若不存在需单独拷贝）：  
+  `.../cw-elevator-application-V1.0.0.20211103/cw-elevator-application-V1.0.0.20211103.jar`。
+- **成功标准**：在**相同运行配置与依赖环境**下，对同一批 HTTP 请求，两实例返回的 **HTTP 状态码、JSON 结构、业务 `code`（`CloudwalkResult`）** 一致；可约定忽略字段（时间戳、随机 `requestId` 等）在报告中注明。
+
+## 2. 约束与先决条件
+
+1. **双进程**：旧版默认端口 `18080`，新版 `18081`；均通过**同一套**外置或环境变量 `spring.config` 指向上游/库（与现网联调一致时才有可比性）。
+2. **无历史 JAR**：本仓库中若不存在上述 `*.jar`，仅完成构建与**框架/离线用例**；等效性验证需在拿到 JAR 后执行 `scripts/run_elevator_parity.sh`。
+3. **健康检查**：优先 `GET /actuator/health`；若基线为 Spring Boot 1.5 且 `management` 基路径不同，由脚本 `tools/elevator_api_parity/parity/health.py` 自动探测回退。
+
+## 3. 子任务分解
+
+| 序号 | 任务 | 产出 |
+|------|------|------|
+| T1 | Maven 发布包构建 | `target/cw-elevator-application-2.0.0.jar` |
+| T2 | 端点目录与用例体 | `tools/elevator_api_parity/api_catalog.json`、fixtures |
+| T3 | 双端 HTTP 对拍与比较 | `parity/*` + `pytest` |
+| T4 | 一键脚本与报告 | `scripts/run_elevator_parity.sh` → `report/parity-*.md` |
+| T5 | 在联调环境实跑、签字发布 | 人工/运维 |
+
+## 4. 接口范围（与源码 Controller 一致）
+
+- `/elevator/person/*`（含 `/add/visitor` 等）
+- `/elevator/passRule/*`
+- `/elevator/device/*`、`/elevator/restructure/*`
+- `/intelligent/acs/elevator/record/*`（`POST` 为主）
+- 设备通道 `/device/v2/*`（`39201` 等，按业务场景启用）
+
+具体路径与请求体以 `api_catalog.json` 为准，可按现网场景追加 `fixtures/*.json`。
+
+## 5. 非目标
+
+- 不替代集成环境全链路压测、安全扫描。
+- 不强制在一台空库机子上与线上一致（需**相同数据与上游**才可比）。
+
+## 6. 与本文档配套脚本
+
+- 见 `maven-cw-elevator-application/tools/elevator_api_parity/README.md`。
+- 报告模板：`docs/elevator-api-parity/REPORT-TEMPLATE.md`（实跑时由 `generate_report.py` 自动填充为 `tools/elevator_api_parity/report/parity-*.md`）。

+# elevator_api_parity — 新旧 JAR 接口对拍
+
+## 环境
+
+- Python 3.8+  
+- 安装：`pip install -r requirements.txt`（在**本目录**下执行）
+
+## 环境说明
+
+本机若安装过 `allure_pytest` 等全局 pytest 插件且与 Python 版本冲突，请执行：
+
+`export PYTEST_DISABLE_PLUGIN_AUTOLOAD=1`（`run_elevator_parity.sh` 已自动设置）后再跑 `pytest`。
+
+## 快速使用
+
+1. 构建新 JAR（在 reactor 根目录、JDK8）  
+   `mvn -DskipTests clean package`  
+   得到：`../cw-elevator-application-starter/target/cw-elevator-application-2.0.0.jar`  
+2. 将历史 JAR 放到 `cw-elevator-application-V1.0.0.20211103/cw-elevator-application-V1.0.0.20211103.jar` 或设 `ELEVATOR_JAR_LEGACY`。  
+3. 准备**与现网相同**的 `application.yml`（或目录），如 `ELEVATOR_SPRING_CONFIG=file:/path/to/application-elevator.yml`。  
+4. 从仓库**反编译**根或本目录执行：  
+   `../../scripts/run_elevator_parity.sh`（见该脚本内环境变量说明）
+
+或手动启动两实例后：
+
+```bash
+export ELEVATOR_BASE_OLD=http://127.0.0.1:18080
+export ELEVATOR_BASE_NEW=http://127.0.0.1:18081
+export ELEVATOR_HEADER_BUSINESSID=...   # 与现网/联调一致
+# ...
+cd tools/elevator_api_parity
+python -m pytest tests/ -v --tb=short
+```
+
+## 配置
+
+- `api_catalog.json`：对拍端点、方法、fixture 文件名、说明。  
+- `fixtures/*.json`：各接口请求体。  
+- 归一化忽略键可扩展 `parity/compare.py` 中 `DEFAULT_STRIP_PATHS`（如 `data.rows` 内动态字段，谨慎）。
+
+## 报告
+
+- `report/parity-YYYYMMDD-HHMMSS.md`：实跑时由 `conftest` 的 session hook 与 `report/generate_report.py` 组合生成。  
+- JUnit（可选）：`--junitxml=report/junit.xml`
