从零重建 Q1 · Notes ManagerRebuild Q1 · Notes Manager
空文件夹。自己起一个 Vite + React + TS 项目，自己装依赖，把 Notes Manager 的增删改写出来并让四个测试全过。测试文件的 data-testid 一个都不能改。An empty folder. Start a Vite + React + TS project yourself, install the dependencies yourself, and write the Notes Manager add, edit and delete so all four tests pass. Do not change a single data-testid in the test file.
题面在下一页。计时基准是「开考那一刻」的时间戳，存在本机 —— 刷新、切标签页、关掉浏览器再回来都不会重置，也不会把你踢回这一屏。The paper is on the next page. The clock is anchored to the timestamp taken when you start and lives in this browser: refreshing, switching tabs or closing the window and coming back will not reset it, and will not throw you back to this screen.
所以别用它当预览 —— 想先看题的话，那已经不是考场了。So do not use it as a preview. If you look at the paper first, this stops being an exam.
- 从空文件夹开始。自己 npm init、自己装依赖、自己配脚本。脚手架是考试内容的一部分。Start from an empty folder. Run npm init yourself, install deps yourself, wire the scripts yourself.
- 计时期间不许打开对应的课、练习场、模拟考讲解。提示和参考答案要交卷才解锁。While the clock runs, no lessons, no practice page, no walkthroughs. Hints and the reference answer unlock only after you hand in.
- 查官方文档、查报错、查 API 签名都允许 —— 真实考试也允许。抄这个站里的答案不允许。Official docs, error messages and API signatures are fair game, same as the real assessment. Copying this site's answers is not.
- 时限到了不会强制打断。计时器变红，交卷记录里标「超时」—— 什么时候停由你决定，但记录如实。Hitting the limit does not stop you. The clock turns red and the attempt is tagged over-time. You decide when to stop, the record stays honest.
- 交卷后先逐条勾验收命令的真实结果，再看提示和答案。顺序不能反。After handing in, tick the real result of each acceptance command first. Hints and answers come after that, not before.
- 中途放弃也会记一条「放弃」，而且抹不掉。记录难看才有约束力。Giving up records a gave-up attempt, and it stays. A record you can quietly delete constrains nobody.
它是源项目里那道题的「从零重写」版：不给脚手架、不给起始代码，只给需求和验收命令。参考答案就是源项目里的真实实现。It is the from-scratch version of a task in the source project: no scaffold, no starter code, only requirements and acceptance commands. The reference answer is the real implementation from that project.
