How the verdict works
The fair rule: a trade is Fair when the gap between the sides is no more than 10 percent of the larger total, the band traders themselves use. Past the band, a gap of up to 25 percent reads as a plain Win or Lose, and anything bigger is a Big Win or Big Lose, always from your side.
Mutations: on the income yardstick, picking a mutation applies its documented multiplier (Gold 1.25x, Rainbow 10x, Crystal 13x and the rest) to that brainrot's income. Mutations do not change buy cost, so the mutation picker is ignored on the cost yardstick. Five brainrots have no published buy cost; on the cost yardstick they count as unknown and the checker says so instead of inventing a price.
What this cannot see: demand, rarity hype and whatever a specific buyer wants tonight. Two brainrots with identical income can trade very differently. Use the verdict as the floor of the conversation, not the whole conversation.
