Routed through 4 poolsSeveral swaps where a token one leg received is the token the next leg sends — a route through pools rather than independent trades.derivedFollows from combining facts (for example a deposit log together with native value). Reasonable, but a reading rather than a statement.#19 #27 #31

Tokens were swappedA `Swap` log, the standard pool event. The evidence links show how many logs there were — the count is deliberately not stated as a number of swaps, because a router re-emits the pool’s event under its own address.confirmedRead from a standard event or a structural fact of the call tree — the transaction says this outright.#19 #27 #31

Tokens were minted: USDS, sUSDSA transfer whose sender is the zero address. Tokens came into existence here.confirmedRead from a standard event or a structural fact of the call tree — the transaction says this outright.#11 #16

A spending allowance was setAn `Approval` log: an allowance was set, letting a spender move tokens later. Nothing moved in this transaction because of it.confirmedRead from a standard event or a structural fact of the call tree — the transaction says this outright.#2 #5 #6

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.
