Edge is closed source. You have no way of verifying the build of Chakra used is the same as the open source version. Well it might be possible to reproduce a build of Chakra to do a binary comparison but i am not aware of anyone doing it.

There's nothing stopping you from compiling https://github.com/Microsoft/ChakraCore and checking if Chakra.dll matches that which is distributed with Edge.

AFICT you cannot build a like-for-like chakra.dll from ChakraCore due to https://github.com/Microsoft/ChakraCore#using-chakracore

The chakra.dll that comes as part of Windows/Edge includes the additional parts not included with ChakraCore (at least that is how it reads to me).
