Hanguk Jumin Deungnok Beonho Input

HangukJuminDeungnokBeonhoInput is a headless input for entering South Korea's Resident Registration Number (주민등록번호), South Korea's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to HangukJuminDeungnokBeonhoView.

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: Thirteen digits, displayed as NNNNNN-NNNNNNN. The first six digits encode date of birth (YYMMDD); the seventh digit encodes sex and birth century; digits eight through eleven encode place of registration; the twelfth is a sequence number; the thirteenth is a Modulus-11 check digit over the preceding twelve.
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
• Companion to HangukJuminDeungnokBeonhoView
