# Windows Platform Rules

## Interaction and layout

- Support window resizing without losing unsaved state.
- Use persistent sidebars at expanded widths.
- Support keyboard navigation, visible focus indicators, mouse hover, and context menus.
- Provide discoverable keyboard shortcuts and tooltips for unfamiliar icon-only actions.
- Allow panels to collapse and, where useful, resize.
- Preserve editor state when the window changes size or loses focus.

## Capabilities and permissions

- Use the platform adapter for native file dialogs and application directories.
- Handle file access failures as recoverable errors.
- Account for high-DPI scaling and Windows display scaling.
- Avoid assuming a fixed title-bar or minimum-window size.

## Release requirements

- Validate the packaged installer or distribution format used by the project.
- Test on supported Windows versions and common display scaling settings.
- Verify keyboard shortcuts, context menus, file selection, high-DPI rendering, and resize behavior before release.

## Smoke-test checklist

- Resize the window repeatedly while editing unsaved content.
- Navigate all primary destinations with keyboard and mouse.
- Open, save, and cancel native file dialogs.
- Confirm focus indicators and tooltips are visible.
- Verify the packaged build starts and restores expected application state.
