Verdict
Eight symbols, five possible answers
Each verdict is the first rule that fired, in precedence order. Drag the size to watch cost move — the fee floor is 509.50 bps before any price impact, so the question is never whether a trade is cheap but how far above the floor it lands.

rule 2
cannot be determined: no execution cost could be produced at this size (the pool holds no liquidity, so no size can be costed); zero liquidity: the pool carries a price but nothing stands behind it. This is reported as UNKNOWN rather than SAFE because an absent reading is not evidence of safety
