Ukrayina Reyestratsiyniy Nomer Oblikovoyi Kartky Platnyka Podatkiv Input

UkrayinaReyestratsiyniyNomerOblikovoyiKartkyPlatnykaPodatkivInput is a headless input for entering Ukraine's Реєстраційний номер облікової картки платника податків (РНОКПП), Ukraine's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to UkrayinaReyestratsiyniyNomerOblikovoyiKartkyPlatnykaPodatkivView.

Status: beta — implemented and unit-tested in all seven frameworks; not yet exercised in a composed flow.

Implementation Notes

• Renders as <input type="text">
• Format: Ten digits. The first five encode date of birth as the number of days elapsed since 1 January 1900; the next four are a registration sequence number, whose own last digit's parity encodes sex (odd male, even female); the tenth digit is a check digit computed with a weighted-sum algorithm over the first nine digits.
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
• Companion to UkrayinaReyestratsiyniyNomerOblikovoyiKartkyPlatnykaPodatkivView
