Make Surface remote debugging and classroom workflows viable: always-on
structured logs with one-click zip export, a single AppShell chrome,
OOXML PPTX/DOCX annotation without LibreOffice, and a first-class sticky
board. Also drop spike/legacy ink widgets and tighten pen feel
(predictor, PenInfoHistory, page-tile layer).

# BadNote
Local-first Surface Pen note-taking app with PDF/PPT annotation.
Local-first Surface Pen note-taking app with PDF / PPTX / DOCX annotation.
All notes, documents, search, and OCR run on your device. No server is required to use the app.
## Features
- Ink notes with Surface Pen (pressure, stabilizer, undo/redo)
- PDF and PPT import with page-level annotation
- Unified shell: Library · Sticky board · Search · Settings
- Ink notes with Surface Pen (pressure, predictor, undo/redo)
- PDF annotation + native OOXML PPTX/DOCX viewers (no LibreOffice required)
- Infinite sticky board with `[[wikilinks]]` / backlinks
- Full-text search over note titles, typed text, and OCR results
- **Local OCR** — pluggable, fully on-device. An embedded ONNX recognition
backend (cross-platform, CPU/iGPU) with a graceful fallback to the platform's
built-in OCR (Windows). See [Local OCR](#local-ocr).
- Always-on diagnostics + one-click diagnostic pack export (Settings)
- **Local OCR** — ONNX when bundled, else Windows WinRT
## Build (Windows)

# Surface 验收清单（诊断包驱动）
AI 无法坐在 Surface 前时，用本清单 + **设置 → 诊断 → 导出诊断包** 闭环。
## 准备
1. `flutter build windows --release` 或 profile 安装包
2. 打开 BadNote → 设置 → 确认「导出诊断包」可用
3. 准备：Surface Pen、一份 20+ 页 PDF、空白笔记
## MUST #3 — 笔 / 触控仲裁（约 1 分钟）
| 步骤 | 期望 |
|------|------|
| Pen 在 PDF 上书写 | 出墨，压感可见 |
| 单指上下滚 | 滚动页面，不画线 |
| 双指捏缩放 | 缩放，不画线 |
| 手掌搁在屏幕上同时用笔写 | 掌不画线（palm） |
导出诊断包。包内 `pen_events.json` 应出现 `arbiter` 行：`decision=draw`（笔）与 `decision=pan`（指）。
## W3 — 硬件笔按钮
| 步骤 | 期望 |
|------|------|
| 无悬停，直接用笔尾点按 | 擦除而非画线 |
| 按侧键（按你的笔设置） | 触发橡皮擦/平移/撤销 |
| 倾斜笔身书写 | `pen_events` / native summary 中 tilt 非全 0 |
查看 `meta.json` → `penNative`：`orPenFlags` / `orPtrFlags` 在按键时应有非零位；`historyCount` 可 >1。
## MUST #4 / #5 — 流畅（profile）
1. `flutter run --profile`
2. 打开大 PDF，快速 fling + 捏缩放 30 秒
3. 导出诊断包 → `frame_samples.json` 中 `overBudget` 占比主观可接受；体感不掉帧
## 手感主观
- 快速甩笔：笔尖无明显拖尾/点状塌缩
- 缩放后页面不长时间白闪（若仍闪，在包内搜 `zoom` / `rebaseline`）
## 回传
把 `badnote_diag_*.zip` 发回即可；无需录屏（可选）。
