+# BASE-HARNESS-01 最小发布包浏览器采集服务
+
+- 日期：2026-09-10；分支：codex/compatible-modernization；起点：1d705b30。
+- 提交主题：`test(refactor): [BASE-HARNESS-01] add isolated published API fixture`。
+- BASE-02 的独立前置子任务；验收范围是夹具与 HTTP 服务，不包括实际浏览器 API 基线。
+
+新增本地服务，从已校验 tarball 提供指定 JS 成员、从 docs 提供本地媒体；固定路由、限定报告写入和大小，缓存不进入仓库。api.html/api.js 准备公开描述符、配置、同步插件及事件调用采集；没有修改生产包或公开接口，没有新增依赖。
+
+`node --test refactor/scripts/browser-server.test.mjs` 1 项通过：精确 tarball 字节、页面路由、媒体 Range、无效 Range、路径越界、未知产物和异源报告拒绝。`node --check refactor/fixtures/api.js` 与计划检查通过。Node 25.2.1，Windows。
+
+Chrome 工具打开页、读取清单、重置后重试均失败，不能取得真实页面报告。用户明确答复先继续其他实施任务；BASE-02 标 blocked 并保留完整范围，后续恢复浏览器连接再捕获。HTTP 测试不能替代浏览器。服务和夹具维护说明见 fixtures/README.md。
+
+本子任务完成后独立提交，下一项 ENG-01。可回退本提交，不影响生产功能；临时测试进程和缓存不代表测试完成。

+# 发布基线浏览器夹具
+
+`node refactor/scripts/browser-server.mjs` 在 127.0.0.1:8083 启动独立测试服务；ARTPLAYER_TEST_PORT 可更换端口。它不启动或修改用户的 Chrome，也不占用 docs 的 8082 开发服务。
+
+- `/fixtures/api.html` 加载固定核心/chapter tarball 的真实 JS，准备捕获描述符、默认配置、utils/子系统/插件形状及基础调用。
+- `/releases/<name>/<member>` 只读取 releases.json 明确登记的成员；启动时核对 archive 完整性，不使用未编译源码或 CDN latest。
+- `/assets/sample/` 读取本仓库样本，支持普通 bytes 范围请求。当前服务用于最小基线；不是完整 ENG-05 故障注入或 HTTP Range 兼容实现，不支持后缀/多段 Range。
+- 页面将 `public-api` 报告发送给同源 `/reports/api`，服务器保存 refactor/.cache/reports/api.json。最多 1 MiB；其他 Origin 和未知写入路径失败。临时报告不能自动覆盖冻结快照。
+
+运行 `node --test refactor/scripts/browser-server.test.mjs` 验证真实 HTTP 服务返回原始 JS 字节、样本范围和路由隔离；`node --check refactor/fixtures/api.js` 只检查脚本语法。两者不能证明页面能在浏览器运行。
+
+2026-09-10：Chrome 连接服务连续失败，用户要求先继续其他任务；api.html 尚未实际执行，没有 API 快照或浏览器通过记录。BASE-02 保持 blocked；恢复连接后打开完整 URL，确认页面 PASS、没有错误，再核对报告和来源、生成持久基线。
+
+夹具与报告路径由基线任务维护；ENG-05 可复用并扩充受控等待、媒体错误和正式自动化。api.js 依据已核对源码设计断言，真实发布行为如有不同应调查并记录，不能修改断言来盲目通过。

+BASE-01 已提交 `1d705b30`。BASE-HARNESS-01 完成发布包采集页面/本地 HTTP 服务及 1 项真实 HTTP 测试，详见 [交付记录](changes/2026-09-10-BASE-HARNESS-01-browser-fixture.md)。BASE-02 因 Chrome 连接失败保持 blocked；用户要求先继续其他实施任务，没有伪造浏览器基线。

 2026-09-10，goal 开始执行。固定核心 5.4.0/chapter 1.1.0 的真实 tarball、47 个成员哈希和支持范围未知项。核心工作区 5.4.1 未发布，两包 registry gitHead 版本过旧，均已如实记录。详见 [BASE-01 交付](changes/2026-09-10-BASE-01-published-baseline.md)。
