(In the latest version of the bill being negotiated in Congress, the language to sunset Direct File has been removed, but this of course could change due to the fluidity of the situation; regardless, we are all better off having learned from this and having access to the source code)
the code they released was everything that is necessary to run Direct File in development, but they removed code relating to MeF (the IRS's online submission API) and SADI (the IRS's auth system which is integrated with ID.me). most of the code is the backend, Fact Graph (which is a very complex rules engine), the client app (both the form and the screener when you go to directfile.irs.gov), and the state tax API
it works with multiple W-2s I'm pretty sure. the goal is to make it work for everyone which is pretty difficult but I'm motivated to at least work on getting it to work with IRAs because I have one and I want to use this for next year
