+  legacy packed instruction JSON support for older result databases.
+- Added `scaled_disequilibrium` and `beta` to selected-pair theoretical
+  execution displays.
+- Improved VS Code notebook usability with the `jupyter_bokeh` dependency,
+  direct Plotly figure rendering, and a dropdown Analyze control for individual
+  pair selection.
+- Made the Panel app use the dark theme by default and reduced the sidebar
+  width from 430 px to 215 px with responsive sidebar controls.
+- Expanded tests and notebook verification coverage for the new database schema
