As I understand it, ARC on the other hand doesn't care what the mutation is, but just proves a chain of handling; if hop N+1 observes that N liked the message and N+1 trusts N, then N+1 can also like the message even if it was modified in transit.
In effect, ARC says "I broke the signature, but before I did, it validated (or didn't)" and then ARC creates a chain of identifier certifications by the breaking entity, their assertion, and every handler after that.
