> every Wordle solver website says I only have 2

There are two different Wordle word lists--the set of legal guesses (roughly 13k) and the set of words in the solution list (roughly 2k). The latter list is curated to be a set of fair, interesting words, excluding plurals and more obscure words. Most Wordle solvers use knowledge of what words are in the Wordle solution database to pare down the set of "possible words". But with Don't Wordle, the "legal guess" list ends up being the more interesting one to show "remaining possibilities" for.

https://scoredle.com/ is a site that shows possible remaining words using the larger "legal guess" list, so you can see that you could have also guessed "SOCAS".

> Another point of confusion is that the first row says 2318 possible words, but there only seem to be 2309 words in the dictionary in the code

There were 2318 remaining possible words AFTER your first guess, which eliminated ~11k possibilities.
