use SlashLab\Numerik\Numerik;

// Simple boolean check
Numerik::pesel()->isValid('92060512186');  // true
Numerik::nip()->isValid('5260250274');     // true

// Rich validation result with failure reasons
$result = Numerik::pesel()->validate('92060512185');  // wrong checksum digit
$result->isFailed();                       // true
$result->getFirstFailure()->reason;        // ValidationFailureReason::InvalidChecksum

// Parse to value object
$pesel = Numerik::pesel()->parse('92060512186');
$pesel->getBirthDate()->format('Y-m-d');  // '1992-06-05'
$pesel->getGender();                      // Gender::Female

// Try-parse — returns null on failure instead of throwing
$nip = Numerik::nip()->tryParse('5260250274');
$nip?->getFormatted();                     // '526-025-02-74'


Numerik::nip(strict: false)->isValid('1111111111');  // true
Numerik::nip(strict: true)->isValid('1111111111');   // false — all-same-digit
