New contract with similar bytecode to exploit template

Evidence summary #

The July 2025 v1 exploit created a known reentrancy exploit template (gmxPositionCallback callback reentrancy pattern in executeDecreaseOrder). However, GMX v2 architecture closes this path: short average price calculation occurs in the same contract as order execution, eliminating the cross-contract reentrancy surface. No contract with bytecode similarity to a GMX v2-specific exploit template documented in public data. V1 template exists in public hack DB but is not applicable to v2 architecture.
