summary
Shows a practical rethinking of notebooks: code cells become reactive DAG nodes with immutable globals, updates propagate automatically, and deletion triggers errors rather than silent desyncs. Demos actually build: a draw-data anywidget that auto-installs deps via uv, returns a Polars dataframe, links to DuckDB/SQL cells, generates Altair charts that select subsets, hooks to LLMs (OpenRouter / Cloud Code) for SQL or Python, exports to a runnable Python file, runs as an app, and the widgets and gamepad annotation pipeline work end to end.
