I'll create a Next.js application for the Clean Check system based on your specifications. This will include both the committee-side and project-side interfaces with all the required functionality.

I've created a comprehensive Clean Check system based on your specifications. The application includes:

Committee-side Features:

1. Main Dashboard (/committee/sst/page.tsx)

   • List view of all clean check assignments
   • Filtering by status, base location, manager, and date
   • Detailed cards for each assignment

2. Overall Progress Check (/committee/sst/check/page.tsx)

   • Summary table showing progress by location
   • Detailed status breakdown for each base
   • Filterable by date and location

3. System Settings (/committee/sst/settings/page.tsx)

   • General settings (Slack notifications, auto-assignment)
   • Cleaning standards configuration
   • Notification settings for different channels

4. QR Code Management (/committee/sst/qrcode/page.tsx)

   • Generate QR codes for all assignments
   • Filter and search for specific assignments
   • Print and download options

Project-side Features:

1. Clean Check Request Page (/user/sst/[placeId]/page.tsx)

   • Accessed via QR code by projects
   • Shows project information and cleaning standards
   • Button to request clean check (changes status to "requested")
   • Different UI states based on current status

Components and Data:

1. Clean Check Card - Displays assignment details with expandable view
2. Mock Data - Sample data for testing the application

The system follows the flow described in your specifications, where projects scan QR codes to request checks, committee members dispatch inspectors, and the status is tracked through various states (unrequested, requested, dispatched, awaiting inspection, re-cleaning, completed).
