Good, I can see the admin panel already has Level 1 implemented in the Remain Inventory slide-over. Let me check the rest of the file and also check what operator panel looks like:

Good, I can see the Admin panel already has Level 1 implemented correctly. The spec says the two issues are:

1. Role switcher is missing - need to add a user dropdown with "View as" section
2. Remain Inventory drill-down skips Level 1 - but looking at the code, Level 1 IS implemented correctly (it starts at level 1 and shows distributors)

Let me verify the Remain Inventory is working correctly, and then add the role switcher. I'll create a layout with header that includes the role switcher and update the page to use it:

Now let me create a simple Operator Dashboard placeholder and update the page to use the role context:

Now let me update the main page to use the role context and show the appropriate dashboard based on the selected role:

Now I need to update the panel components to remove their own header since we now have a global header. Let me update the admin panel:

Now let me check the operator management panel to remove the min-h-screen there too:

I've implemented both fixes from the spec:

1. Role switcher in user dropdown - Added a new AppHeader component with a user dropdown that includes:

   • Language selection (English, Hebrew, Spanish)
   • A "View as" section with a dropdown to switch between Admin/Distributor/Operator roles
   • The switcher respects permissions (Admins see all 3, Distributors see Distributor/Operator, Operators don't see the switcher)
   • Switching instantly changes the dashboard layout without page reload
2. Remain Inventory drill-down Level 1 - The admin panel already had Level 1 correctly implemented with distributor rows, amber bars, and click-to-drill functionality. I verified it starts at level 1 and shows all distributors before drilling into a specific one.

The role context (lib/role-context.tsx) manages the current user and selected view role, and the main page renders the appropriate dashboard component based on the selected role.

I understand the screenshots - they show the current implementation with various tag pills (NFC, Defective, Inventory, OFFLINE), verbose labels, and inline timestamps that all need to be replaced with the cleaner universal DeviceRow component.

Let me build the DeviceRow component and demo page according to the spec:

Now let me create the DeviceRow component according to the spec:

Now let me create the demo page showing all state combinations in both light and dark mode:

Now let me update the main page to show a link to the demo page:

The main page structure looks good. Let me also check that the DeviceRow component is properly exported and usable. Let me verify the demo page loads correctly by checking if there are any missing dependencies:

All dependencies are in place. I've created the Universal DeviceRow component with:

1. Communication dot - Green/amber/red based on last seen time, with hover tooltip showing relative timestamp
2. Device identity - Bold name + muted #id and IMEI below
3. Active minutes - Right-aligned "X min" display
4. Warning icon - Only shows when active_min >= 15 AND billing is paused, clickable to enable billing
5. Billable toggle - Custom switch with "Billable"/"Paused" label, optimistic updates with loading spinner
6. Three-dot menu - Transfer to operator, Mark defective (red), View details

The component handles all states: default, hover, selected (purple tint + left border), loading (spinner in toggle), and defective (red tint + warning icon instead of dot + hidden toggle).

The demo page at /device-row-demo shows 10 example rows covering all state combinations in both light and dark mode side by side, including the long name truncation test case.
