Smart contract and secret contract

After running the demo Millionaire, I am a bit of confused about the difference between smart contract and secret contract.

I understand the secret contract is mainly designed to handle the dapp logic(in the Millionaire demo are how to add_millionaire and compute_richest).

But what’s the function of the smart contract (i.e. Sample.sol and Migrations.sol) ? 🤔

Stan is mostly following Laura's millionaires project, he mentions a Sample contract so I guess he also ran init in this or a new project.

Can and Ainsley have responded but we should also cleanup any unused smart contract code in the project.
We can also refer to the non-fungible token project for example smart + secret contract usage.
