Start with the natural pattern
EnterJH QH KH and designateQ as wild. The three actual cards already form a same-suit consecutive run. Our checker tests natural interpretations first and labels this a pure sequence.
Do not classify by colour alone
A highlighted wild-rank card is not necessarily being used as a substitute in the displayed interpretation. Read its role. The source reference also distinguishes using a wild-rank card naturally in a straight run.
Compare a different group
JH KH QD withQ designated wild does not have a natural heart queen, butQD may act as a substitute in an impure interpretation. The physical token remainsQD while its assigned role fillsQ♥.
Ask a precise question
Which card is physically present? Which position is it representing? The result becomes easier to explain when those are written separately.
