Local-first infinite canvas prototype
Paradox
North star / never-ending improvementEvery kind of idea, alive on one infinite canvas.
A C++23 native shell hosting a local WebView canvas with structured nodes, pen and pointer tools, outline navigation, an explicit JSON-RPC boundary, deterministic undo concepts, and mock export and sidekick routes.
- Put notes, code, data, drawings, tasks, and diagrams on one canvas.
- Trace every change through a deterministic local journal.
- Turn a canvas into frames, posters, briefs, mindmaps, and export-ready views.
The native Windows shell and substantial local UI build and run, but the backend remains a mock dispatcher. Durable workspace storage, real native exports, production AI adapters, stress evidence, and the broader modular engine are still design or backlog work.

Native host
The Windows shell owns process and webview lifecycle
Win32 -> WebView2 -> local fileRPC contract
Versioned messages gate every native action
handshake -> request -> eventInteraction surface
One dense canvas hosts many kinds of thought
gesture -> scene state -> pixelsUniversal model
Documents and diagrams share one node vocabulary
everything is a nodeGesture layer
Mouse, pen, touch, and keyboard share the work surface
device event -> normalized gestureStructure
The outline mirrors page organization

Palette, rail, menus, and keymap converge on actions
intent -> named commandUndo model
Commands produce reversible mock journal entries

Durable workspace storage is still a design contract
