# 首次加载性能 U1/U3/U7 收尾
|
||||
|
||||
## 用户目标与授权
|
||||
|
||||
- 用户目标：推进 FEATURE-MATRIX「首次加载性能专项」未关项（U1 慢网 n≥20、U3 浏览器瀑布、U7 登录表单可见/50% 降幅如实记录）。
|
||||
- 交付终点：探针代码可复跑、schema 61 部署栈实测证据、FEATURE-MATRIX 专项段落更新、本任务验证节与报告。
|
||||
- 禁止：不 push；不放宽预算阈值；不 rebuild/晋升；不冒 stub/SKIP 为 PASS。
|
||||
- 例外：本机 macOS `agentctl with` 若仍因 `/proc` 不可用，提交走手工等效并在此登记。
|
||||
|
||||
## 范围与非目标
|
||||
|
||||
- 允许：`web/e2e/initial-load-performance.spec.ts`、`web/src/lib/initialLoadMetrics*`、`web/package.json`、`.doc/ops/short-term`、`.doc/test-reports`、`.doc/status/FEATURE-MATRIX.md` 专项段落。
|
||||
- 非目标：改业务功能、放宽预算、整机开机矩阵、test/main 环境。
|
||||
|
||||
## 步骤与验收
|
||||
|
||||
1. [x] 探针默认 `INITIAL_LOAD_SAMPLES=20`；U3 首屏重模块断言；U7 表单可见用例 — 验收：单测绿。
|
||||
2. [ ] 对已部署 `8080` schema 61 跑登录态瀑布 n≥20 — 证据：`assets/2026-09-22-initial-load-closeout/`。
|
||||
3. [ ] 慢网+CPU4× 双档各 n≥20，出 p50/p75/p95；预算失败不放宽 — 证据：`throttled-*-percentiles.json`。
|
||||
4. [ ] U7：本机 Chromium 测 `/ready` 后冷导航表单可见；如实记录相对约 10s 基线是否达 50%（≤5s p75）。
|
||||
5. [ ] 更新 FEATURE-MATRIX 专项段落；`npm test` + `npm run build`。
|
||||
6. [ ] 提交并登记 `head_sha`。
|
||||
|
||||
## 验证与证据
|
||||
|
||||
| 范围 / 被测 SHA | 命令与环境 | 预期 | 实际 / 判定 | 证据 / 脱敏说明 |
|
||||
|---|---|---|---|---|
|
||||
| metrics 单测 | `cd web && npm test`（含 initialLoadMetrics） | pass | 473 pass / 0 fail（本轮） | 终端摘录，无密钥 |
|
||||
| Playwright Chromium | `npx playwright install chromium` | 可 launch | **进行中**：共享缓存锁冲突后改隔离目录；cdn 下载缓慢 | 不入 Git 的 `.playwright-browsers/` |
|
||||
| schema61 登录瀑布 | `RUN_INITIAL_LOAD_BASELINE=1 INITIAL_LOAD_SAMPLES=20 …` | n=20、重模块空、成员项目≤1 | 待跑（浏览器未就绪） | assets 目录；账号仅环境变量名 |
|
||||
|
||||
## 收口与交接
|
||||
|
||||
- 剩余：浏览器安装完成后补跑 U1/U3/U7 实测并关账。
|
||||
- 本地提交 / dev 集成 / 部署 / 远端：分别待记。
