+
+## Implementation Details
+
+### 1. Toast System Design
+
+We have implemented a Toast system using React Context for global state management:
+
+1. Created `ToastProvider` component that:
+
+   - Maintains state of active toasts
+   - Provides methods to add/remove toasts
+   - Handles auto-dismissal timing
+
+2. Created `useToast` hook that provides:
+
+   - `toast()` function for showing toasts
+   - Support for different variants (success, error, warning, info)
+   - Options for customizing duration, actions, etc.
+
+3. Created `Toast` component for rendering individual toasts with:
+   - Appropriate styling based on variant
+   - Accessibility attributes
+   - Close button
+
+### 2. StatusBadge Design
+
+The StatusBadge component:
+
+- Displays status information using color coding and optional text
+- Supports various status types (success, error, warning, pending, etc.)
+- Is accessible with appropriate color contrast and aria attributes
+- Follows the UI-Kit's design system
+
+## Folder Structure
+
+```
+packages/ui-kit/src/
+  components/
+    feedback/               # New directory for feedback components
+      Toast/
+        index.ts           # Re-export
+        Toast.tsx          # Component implementation

+      index.ts
+      ToastProvider.tsx
+      ToastProvider.test.tsx
+  hooks/
+    useToast.ts           # Custom hook for accessing toast functionality
+```
+
+## Test Results
+
+✅ All unit tests passing
+✅ Build successful  
+✅ Components exported correctly
+✅ Accessibility tests passing (after fixing button contrast issues)
+✅ Storybook stories working
+
+## Definition of Done Verification
+
+The original DoD was: "Vitest renders Toast, axe-core passes."
+
+✅ **Vitest renders Toast**: All tests pass, including rendering tests for both Toast and StatusBadge components
+✅ **axe-core passes**: Accessibility tests pass without violations
+
+All tasks have been completed successfully and the implementation meets the requirements outlined in the project plan.
