Bug fixes (Flutter): - Wrap multi-statement DB writes (insert/update/delete note, deleteDocument, deletePageData, OCR FTS merge, migrations) in transactions to prevent data loss on interruption and a read-modify-write FTS race. - Fix PdfDocument leaks on exception (try/finally dispose) and preserve image aspect ratio when stamping images onto PDF pages. - Guard file-picker against empty selection (was .single -> crash). - Fix eraser ConcurrentModificationError and unmodifiable-list crash on PDF pages; capture page synchronously on save to stop wrong-page data loss. - Fix Riverpod DB-not-ready races, broken pull-to-refresh, settings load race, and search N+1; transform stored annotations on PDF page rotation. - Normalize pen pressure for devices without a pressure range. - PPT: single source of truth for slide strokes so ink displays and exports. UI/UX: - Material 3 typography, theme-aware colors (dark-mode fixes), hover cursors and right-click/visible actions on desktop, keyboard shortcuts (undo/redo/ save/find), toolbar overflow handling, friendlier empty states, semantic OCR status badges, relative timestamps, 1-based page indicators, large-deck PPT navigation, and a scratchpad-scope label in split view. Server (optional backend): - Persist JWT secret (was per-process random), block path traversal in storage, fix CORS '*'+credentials, add OCR job ownership checks, last-writer-wins sync guard, constant-time login, and split out heavy OCR deps so the API/tests run without them. CI: Gitea workflows for format+analyze+test (Linux, system sqlite) and a Windows release build; pristine `flutter analyze`, all Flutter and server tests green.

BadNote
Local-first Surface Pen note-taking app with PDF/PPT 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
- Full-text search over note titles, typed text, and OCR results
- Local OCR — handwriting recognition via Windows built-in OCR (Windows desktop)
Build (Windows)
Prerequisites:
- Flutter SDK (3.10+)
- Visual Studio Build Tools with Desktop development with C++
- Developer Mode enabled (for Flutter plugin symlinks)
flutter pub get
flutter build windows --release
Output: build\windows\x64\runner\Release\badnote.exe
If native asset downloads fail (e.g. sqlite3), set a proxy before building:

OCR flow on save:
- Extract typed text from text-tool strokes
- Rasterize handwriting strokes to PNG
- Run Windows OCR on the PNG
- Merge recognized text into the local FTS index for search
Optional server
The server/ directory contains an experimental FastAPI backend (sync + EasyOCR). It is not required for the desktop app and is kept separately for future multi-device sync experiments. See server/README.md.
Development
