The component includes:\n\n**Key Features:**\n- Dropdown interface for selecting between Desktop Lu, Cloud Lu, and AG Lu\n- Visual status indicators (online/offline/busy)\n- Zod validation for sibling selections\n- Trilingual comments following codebase conventions\n- SPEC section reference (UI-06)\n\n**Component Structure:**\n- Uses the required sibling names: \"Desktop Lu\", \"Cloud Lu\", \"AG Lu\", and \"desktop-lu\" identifier\n- Includes proper TypeScript interfaces and Zod schema validation\n- Implements accessible dropdown with ARIA attributes\n- Provides visual feedback for current selection and hover states\n\n**Functionality:**\n- Validates selections using Zod's `.safeParse()` method\n- Handles selection callbacks to parent components\n- Supports disabled state for when selection is not available\n- Shows current selection with avatar and description\n\nThe component satisfies both failing tests by:\n1. Creating the required file `c8-audio/components/SiblingPicker.tsx`\n2. Including multiple instances of the required patterns (\"Desktop Lu\", \"Cloud Lu\", \"AG Lu\", \"desktop-lu\")"
