-默认识别是开的：笔迹停大约一秒，先判断像不像算式。普通句子留在纸上，不送进公式模型。像算式才走本机 CoMER。置信度够就写成公式并更新角落的图，纸上没有确认条。按 R 会对最近的笔迹再认一次。设置里可以关掉自动识别。

-Recognition is on by default. About a second after the ink settles, a text gate decides whether it looks like a formula. Ordinary writing stays on the paper and is not sent to the formula model. Formula-like ink goes to the local CoMER model. A confident reading is written as a formula and the corner plot updates. There is no confirmation strip. R recognizes the latest ink again. Automatic recognition can be turned off in Settings.
+Handwriting is recognized only when you ask: press R, or use the recognize button. Lifting the pen does not recognize it. A text gate decides whether it looks like a formula.

 模型是 CoMER（ECCV 2022）的 INT8 ONNX，权重由 [ink-on](https://github.com/kimseungdae/ink-on) 以 Apache-2.0 分发。它能读一些清楚的短式，不能当作任意手写的完整识别器：认不出就保持笔迹，不会用 `y = x` 充数。单独的 `sigma` 是符号，求和与积分留在纸上，不因此打开坐标系。

-`.github/workflows/package.yml` runs on a push to `main` or `cursor/mathscrap-packaging-*`, and on a pull request into `main`. The `test` job has no extra skip condition, so all three of those runs execute it on `ubuntu-latest`: `npm run lint`, `npm run test:rust`, `npm run smoke`, `npm run smoke:ocr`, `npm run smoke:ai`, `npm run test:pack`, then a dev server, then `npm run e2e:sheet` and `npm run e2e` (one plot per formula). On failure it uploads `e2e-shots`, `e2e-plots`, and `dev-server.log`. Those steps need no secrets. The web bundle, debug APK, and unsigned Windows installer still build only on a push, and only after `test` passes. A pull request does not build installers. `.github/workflows/package-ios.yml` uses a macOS runner only when started by hand. These workflows do not create a GitHub Release.
