The original evidence 「承文副正字單金⿰糸冀燦」is from 正祖 10年 (1786) 4月 15日 11記事.

However, 正祖 10年 9月 25日記事 (less than half year after the date provided in the original evidence) gives 金驥燦（承文博士單）:



▲ {{https://sjw.history.go.kr/id/SJW-G10090250-00800
승정원일기 1611책 (탈초본 86책) 정조 10년 9월 25일 을미 8/26}}

The time, role and the name similarity suggest that both 金⿰糸冀燦 and 金驥燦 refer to the same person.

There are more than 200 occurrences of 金驥燦 in 『承政院日記』, spanned from 1777 to 1812. Here are some examples:


▲ 승정원일기 1408책 (탈초본 78책) 정조 1년 10월 21일 계축 11/20


▲ 승정원일기 1826책 (탈초본 96책) 순조 즉위년 8월 28일 무인 10/28


▲ 승정원일기 2011책 (탈초본 105책) 순조 12년 1월 20일 갑오 21/28

But there is only one occurrence of 金⿰糸冀燦 in 『承政院日記』as is provided in the original evidence, which implies that KC-10007 ⿰糸冀 is not stable enough as 驥. Therefore I suggest pending more evidences.

Based on the HUANG Junliang's comment, KR will withdraw this char.
