It seems some links are dead, e.g. https://github.com/zama-ai/fhevm/blob/main/lib/TFHEExecutor.sol
I am also wondering why you now linking out of the fhevm-backend repo? Wouldn’t the full path within the fhevm-backend repo be sufficient? E.g. https://github.com/zama-ai/fhevm-backend/blob/main/contracts/contracts/TFHEExecutor.sol

I linked files in fhevm-backend repo. What do you mean re fhevm?

@dartdart26 Sorry, I am clearly very tired. I read the old state as the changes and the new changes as the old state.

No worries! I merged it to just move forward quickly. @david-zk Could you please disallow that and require at least 1 approving review?
