Solidity Code We Used

The github repo doesn't contain what's needed to create a byte-compatible contract to what is deployed. We used etherscan's API's to download the source solidity files validated by them. Note that etherscan only does partial validation which does not include the metadata, so the actual source code used may differ some, but it will generated the same byte code.

We built with the same solidity compiler (0.8.7), same optimization flags, and same file paths and were able to get identical byte code except for the contract metadata at the end.
