Trait HopperRefOnly 

pub trait HopperRefOnly: Sealed { }

Marker trait implemented exclusively by Hopper’s four account-data borrow guards: Ref, RefMut, SegRef, SegRefMut.

Use this as a bound on APIs that must accept only drop-guarded borrows. A naked &T or &mut T will fail the bound at compile time, which is the closure proof for Finding 2 of the audit (“borrow safety compile-proven, not just runtime-enforced”).
