Add notebook.json containers with multi-member pages, fix PDF text
editing (size/bold/drag/double-tap), index SidecarText in search, and
share keyboard page shortcuts plus a PDF scrubber.

Redesign the optional FastAPI companion around vault files (manifest /
PUT/GET/DELETE + OCR jobs) instead of legacy strokes_json notes. Wire a
client Server settings panel for health/login. Polish shell UX: l10n for
settings/home/board, sticky-board empty state, and a narrow-screen
diagnostics FAB.

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).

Search now covers handwriting, the PDF text layer, AND scanned
(rasterized) PDFs.
- PdfTextIndexer runs at import: sums the embedded text layer across
pages; if present it stores that as the document body, otherwise the
PDF is rasterized and its rendered pages are OCR'd in the background.
The result lands in the sidecar `pageText` field (distinct from
`ocrText`, the handwriting OCR). Idempotent (skips a sidecar that
already has pageText); degrades gracefully with no OCR engine.
- pdfrx_page_text_source abstracts text/render so it's testable.
- VaultSearchIndex now harvests title + typed text + handwriting OCR +
PDF pageText, so search finds notes, typed PDFs and scanned PDFs.
analyze clean, 409 tests green.
Phase 4. Standalone notes move off SQLite into the vault, like the
PDF annotations.
- "Create notebook" makes a vault folder with a notebook.badnote.json
(BadnoteSidecar docType 'notebook' + a title field), opened via
SidecarRepository.
- PenNoteScreen loads/saves its strokes (page 0) + title to that
sidecar instead of the SQLite Note model.
- note_provider lists notes from a vault scan (VaultService.scanNotes
= folders with notebook.badnote.json and no source file); the doc
scan still excludes them. Delete removes the folder.
PDF/slide editors unchanged; pre-existing SQLite notes migrate in
Phase 5. analyze clean, tests green.
Phase 3. Import becomes a single top-level action beside "Create
notebook" and the library is vault-backed.
- VaultService.createNotebook copies a picked file into a fresh
(de-duplicated) notebook folder under the vault; its sidecar lives
beside it, so annotations travel with the file.
- Home screen: one "Import file" action with a multi-extension picker
(pdf / docx / pptx); routes to the editor by extension.
- The document list is now a vault scan (folders with a source file),
not the SQLite documents table — no cache, always correct.
- PPTX soffice detection fix; DOCX convert-on-import is best-effort
and fails gracefully when LibreOffice is unavailable.

Replace the rejected standalone sticky-card board with the real
feature: place a link anchor anywhere on a PDF page, tap it to open
split view whose right pane is THAT anchor's own infinite scratchpad
(keyed by anchor id) — like a paper sticky-note tab.
- ScratchLink model + scratch_links table (id, doc, page, nx, ny).
- PDF editor: "place link" tool drops/loads/shows tappable markers;
tap opens SplitViewScreen for that anchor; long-press deletes.
- SplitViewScreen rebuilt on pdfrx (was syncfusion), right scratchpad
keyed by scratchLinkId, new brush palette (was AnnotationToolbar).
- Remove board_screen + its test + the home board entry.

Wire the F7 双链 + 无限便利贴 model (Board/LinkGraph) into a
reachable screen. Previously the model existed but had no UI and
no entry point.
board_screen.dart: an infinite InteractiveViewer canvas of
draggable, editable sticky cards. Card text renders [[links]] as
tappable chips that pan to the target card (dangling links styled
apart). A backlinks panel lists "linked from" via backlinksOf.
"Add card" FAB drops a card at the viewport center.
Persistence: a board_cards table (DB v7), one row per card,
debounced 800ms like the ink editors, loaded on open — boards
survive restart. Entry added to the home screen app bar
(dashboard_customize icon).
Ink-on-cards, multi-board management and link autocomplete are
deferred (TODO board-ink / board-multi / board-link-autocomplete).

PPT slides now annotate with the single performant inking engine
(PenCanvas) instead of the old ink_canvas, per "all note features on the
pen-first canvas".
- PenSlideScreen: per-slide normalized strokes over each slide image,
prev/next + slider nav, undo/redo, shared M3 palette, and the pressure
curve / eraser size+mode / palm rejection from the shared canvas.
- slide_export: pure, tested export geometry. Because strokes are now
normalized to the page rect, the PDF exporter maps them straight into
each slide's draw rect — fixing the old exporter's known ink
misalignment (it guessed live-widget size).
- Route PPT import + open -> PenSlideScreen; delete the dead old
ppt_annotator_screen. (ink_canvas/annotation_toolbar remain for
split_view, the last old-canvas screen.)
Tests: slide_export geometry (4). flutter analyze: 0 issues. Suite: 269/269.
Notes now use the single performant inking engine (PenCanvas) instead of
the old ink_canvas, per "all note features on the pen-first canvas".
- ink_stroke_adapter: pure InkStroke<->PenStroke bridge (normalize against
a logical note page; drop non-freehand shapes/text). Round-trip tested.
- pen_palette_widgets: shared M3 ToolButton/PaletteDivider/RoundIconButton
so PDF + note editors use identical chrome (PenEditorScreen migrated to
them; its private copies deleted).
- PenNoteScreen: PenCanvas over a white logical page, undo/redo, title,
save -> Note.strokes (+ local OCR for search). Pressure curve, eraser
size/mode and palm rejection all inherited from the shared canvas.
- Route home (new/open) + search note hits -> PenNoteScreen; remove the
now-redundant "Pen Canvas (beta)" spike button; delete the dead old
note_editor_screen.
Tests: ink_stroke_adapter (5) + pen_note_screen widget (load + commit, 2).
flutter analyze: 0 issues. Full suite: 265/265.
The app had zero localization ("软件多语言做了吗" — no). Add Flutter's
official gen-l10n pipeline and localize the core flow the user sees.
- pubspec: flutter_localizations + intl + generate: true
- l10n.yaml + lib/l10n/app_en.arb + app_zh.arb (37 strings)
- main.dart: localizationsDelegates + supportedLocales (follows OS locale)
- pen editor: all tool tooltips, page pill, error states localized
- home: app bar actions + empty-state buttons localized
Proven end-to-end: l10n_test pumps the same widget under Locale('en')
and Locale('zh') and asserts English vs Chinese strings resolve.
flutter analyze: 0 issues. l10n_test: 3/3 pass.

The night's pen-first rebuild (PenEditorScreen + PenCanvas + zoom fix +
eraser + M3 tool palette + render cache) was unreachable from the running
app: home_screen opened the OLD PdfAnnotatorScreen, so the user saw zero
change. Wire both PDF-open sites (import + open-existing) to PenEditorScreen,
making the entire editor/* stack LIVE on the real PDF path.
flutter analyze: 0 issues.

Clean-room reimplementation of Saber's input model: we own the gesture
pipeline so pen draws with real pressure (perfect_freehand), two-finger
pinch zooms/pans, and palm is rejected (stylus-priority, 2nd-pointer
cancels stroke). pdfrx renders one page at a time (PdfPageView, no
gestures) under a shared transform; page-based nav. Material You theme
via dynamic_color (system accent + seed fallback) and a floating tonal
tool palette + page pill. Old pdfrx-overlay spike no longer wired.
Add pdfrx 2.4.4. PenCaptureRegion routes stylus to ink (arena-bypass
via PenCaptureBinding) while touch falls through to pdfrx scroll/zoom.
Spike pane hosts PdfViewer with page-overlay ink at normalized coords +
frame-time HUD; reachable from home screen for on-device testing.
Bench/coordinate harness under integration_test. Generated assets are
gitignored (regenerate via tool/gen_*.dart).
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.
