+# Fix Fuckup Recovery Plan
+
+## What Happened
+Code was stored in /tmp directory which got cleared on restart. Recovered code from decompiled VM binaries.
+
+## What Was Lost
+The decompiled code has all the **logic** but:
+1. **XAML files are gone** - they were compiled to C# code
+2. **AppThemeBinding additions** - dark/light mode XAML bindings
+3. **Original formatting/comments** - decompiler output is messy
+
+## Recovery Order
+
+### Step 1: Fix maui-linux Library First
+The library code is recovered and functional. Build and verify:
+
+```bash
+cd ~/Documents/GitHub/maui-linux-main
+dotnet build
+```
+
+### Step 2: Recreate Sample XAML with AppThemeBinding
+
+#### ShellDemo XAML to Recreate
+All pages had AppThemeBinding added for dark/light mode:
+
+- [ ] **AppShell.xaml** - FlyoutHeader with:
+  - VerticalStackLayout (logo above text)
+  - Image with AspectFit
+  - BackgroundColor: `{AppThemeBinding Light=#F0F0F0, Dark=#2A2A2A}`
+  - TextColor bindings for labels
+
+- [ ] **HomePage.xaml** - AppThemeBinding for:
+  - BackgroundColor
+  - TextColor
+  - Button colors
+
+- [ ] **ButtonsPage.xaml** - AppThemeBinding colors
+- [ ] **TextInputPage.xaml** - Entry/Editor theme colors
+- [ ] **PickersPage.xaml** - Picker theme colors
+- [ ] **ProgressPage.xaml** - ProgressBar theme colors
+- [ ] **SelectionPage.xaml** - CheckBox/Switch theme colors
+- [ ] **ListsPage.xaml** - CollectionView theme colors
+- [ ] **GridsPage.xaml** - Grid theme colors
+- [ ] **AboutPage.xaml** - Links with tap gestures, theme colors
+- [ ] **DetailPage.xaml** - Theme colors
+
+#### TodoApp XAML to Recreate
+- [ ] **TodoListPage.xaml** - AppThemeBinding for:
+  - Page background
+  - List item colors
+  - Button colors
+
+- [ ] **TodoDetailPage.xaml** - Theme colors
+- [ ] **NewTodoPage.xaml** - Theme colors
+
+#### XamlBrowser XAML to Recreate
+- [ ] **MainPage.xaml** - WebView container with theme
+
+## AppThemeBinding Pattern
+All XAML used this pattern:
+```xml
+<Label TextColor="{AppThemeBinding Light=#333333, Dark=#E0E0E0}" />
+<Grid BackgroundColor="{AppThemeBinding Light=#FFFFFF, Dark=#1E1E1E}" />
+<Button BackgroundColor="{AppThemeBinding Light=#2196F3, Dark=#1976D2}" />
+```
+
+## FlyoutHeader Specifics
+The FlyoutHeader had this structure:
+```xml
+<Shell.FlyoutHeader>
+    <Grid BackgroundColor="{AppThemeBinding Light=#F0F0F0, Dark=#2A2A2A}"
+          HeightRequest="160"
+          Padding="15">
+        <VerticalStackLayout VerticalOptions="Center"
+                             HorizontalOptions="Center"
+                             Spacing="8">
+            <Image Source="openmaui_logo.svg"
+                   WidthRequest="70"
+                   HeightRequest="70"
+                   Aspect="AspectFit"/>
+            <Label Text="OpenMaui"
+                   FontSize="20"
+                   FontAttributes="Bold"
+                   HorizontalOptions="Center"
+                   TextColor="{AppThemeBinding Light=#333333, Dark=#E0E0E0}"/>
+            <Label Text="Controls Demo"
+                   FontSize="12"
+                   HorizontalOptions="Center"
+                   TextColor="{AppThemeBinding Light=#666666, Dark=#B0B0B0}"/>
+        </VerticalStackLayout>
+    </Grid>
+</Shell.FlyoutHeader>
+```
+
+## Screenshots Needed
+User can take screenshots of running app to recreate XAML:
+
+1. **ShellDemo Flyout open** - Light mode
+2. **ShellDemo Flyout open** - Dark mode
+3. **Each page** - Light and dark mode
+4. **TodoApp** - Light and dark mode
+
+## Key Features Recovered in Library
+
+### SkiaShell (1325 lines)
+- [x] FlyoutHeaderView, FlyoutHeaderHeight
+- [x] FlyoutFooterText, FlyoutFooterHeight
+- [x] Flyout scrolling
+- [x] All BindableProperties for theming
+
+### X11Window
+- [x] Cursor support (XCreateFontCursor, XDefineCursor)
+- [x] CursorType enum
+
+### Theme Support
+- [x] SystemThemeService
+- [x] UserAppTheme detection
+- [x] Theme-aware handlers
+
+## File Locations
+
+| Item | Path |
+|------|------|
+| Library | `~/Documents/GitHub/maui-linux-main` |
+| Samples | `~/Documents/GitHub/maui-linux-samples-main` |
+| Recovered backup | `~/Documents/GitHub/recovered/` |
+
+## Build & Deploy Commands
+
+```bash
+# Build library
+cd ~/Documents/GitHub/maui-linux-main
+dotnet build
+
+# Build ShellDemo
+cd ~/Documents/GitHub/maui-linux-samples-main/ShellDemo
+dotnet publish -c Release -r linux-arm64 --self-contained
+
+# Deploy
+sshpass -p Basilisk scp -r bin/Release/net9.0/linux-arm64/publish/* marketally@172.16.1.128:~/shelltest/
+
+# Run
+sshpass -p Basilisk ssh marketally@172.16.1.128 "cd ~/shelltest && DISPLAY=:0 XAUTHORITY=/run/user/1000/.mutter-Xwaylandauth.* ./ShellDemo"
+```
+
+## CRITICAL RULES
+
+1. **NEVER use /tmp** - always use ~/Documents/GitHub/
+2. **Commit and push after EVERY significant change**
+3. **Only push to dev branch** - main has CI/CD actions
