The playoff_matches.isScoring column defaults to true in the database. Brackets
created before this column was added (or before the migration set correct values)
have isScoring=true on play-in rounds that should be false. When recalculate-floors
replayed those matches, it took the "scoring round" path; since "Play-In Round 1"
isn't in ROUND_CONFIG, config===null, and the loser was assigned finalPosition=0
regardless of loserAdvances — permanently eliminating teams like the Suns who had
a second play-in game remaining.
Fix: build a round→isScoring lookup from the bracket template before replaying
matches and use it as the source of truth, falling back to the DB field only when
the template doesn't define the round. This ensures non-scoring play-in rounds
are always processed with isScoring=false so the loserAdvances guard fires
correctly.
