Evidence

The figures behind the verdict, as the engine served them.

Read cost together with reachability: a figure on an unreachable rung says how far the book goes, not what the move costs.

Cost to move the price by each delta, through all venues and through the order book alone, with whether the target is reachable at all.

Reachability on the all-venues ladder is unconditionally true whenever an active pool exists, because a constant product curve has no upper price bound. The order-book-only column is the one that answers whether a target is attainable, and it is the one Keel itself uses.

Highest price the book can reach
not computed

Absorbing every ask. Not computed when an active pool exists, because a constant product curve has no highest price

Cost to reach it
not computed

Every ask below that price. Catches an attack that lands between two rungs of the ladder
