The current lead gives the account dated anchors—1989, 2007—that can be checked directly. The linked authority record independently contributes the date 1989-05-15. Its value is orientation rather than verdict, with Sunny, singer and South providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Sunny (singer)”, the useful work is to connect “south Korean-American singer” to the records capable of establishing context and consequence.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q233894. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989 and 2007.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
