use Illuminate\Database\Eloquent\Model;

    // Assuming model has the following fields
    // id, status, registration_date, and a one to many

// Schedule task somewhere - ran nightly, or whenever
// 
// This way you can refresh the status only on certain groups
// of data - for example, if the business flow means that once
// they become compliant, they can't go back, there is no need
// to refresh their status anymore 
//
User::where('raw_status', '<>', 'compliant')->refreshStatus();

// Alternatively, the schedule could chunk results and do an update
// only to those not updated in the last 24 hours
//
