(https://youtu.be/Vte4nly_Neg) with exactly TWO of the six Green>Blue>Pink voters flipping their top two (to Blue>Green>Pink; scores 0,4,5,3). The video's round-2 hypothetical ("what if Green were eliminated instead of Blue?") becomes the actual RCV-IRV count in the companion race — and STAR barely moves: scores are now Blue 46, Purple 46, Pink 44, Green 36; the two co-leaders are exactly the two finalists (no tiebreak needed — both advance) and Blue wins the same runoff as in BV2176, 10-9. The flip that upended RCV-IRV's whole story merely swapped which finalist tops the scoring round: Blue stops being a Runoff Reversal winner and becomes the score co-leader.
