Gas hotspotsGas each call burned BY ITSELF — its own consumption minus everything it invoked, since the wire reports gas inclusively. The share is of the root call's gas, not of the transaction fee.
Repeated callsThe same executing code called with the same 4-byte selector more than once. On an arbitrage this is the shape of the strategy itself — no semantic layer needed to see it.
ParticipantsDistinct addresses called, how many calls each took, and how many frames ran someone else's code in their caller's storage (DELEGATECALL/CALLCODE).
