Mission briefing

Vertex Desk swapped 40 WETH for ORCA on a public router. The quote on screen said roughly 118,000 ORCA. The fill came back at 104,880, eleven percent worse, and the desk wants to know who took the difference. Here are the router's swap events from four consecutive blocks, in the order the chain executed them: block first, then position inside that block. The desk wallet is 0x4d81ac9f2b7e61d0cc35a84f19e7b2065da3f7c8. Somebody paid fifteen times the going gas price to be standing on both sides of that trade. Name their address.
