On start of an interactive shell, is there something that gets called between ~/.zshenv and ~/.zshrc? My PATH is getting changed between them

According to the docs, the order of .zsh files is

.zshenv
.zprofile
.zshrc
.zlogin

As suggested by the docs, I put my $PATH in .zshenv. I echo it there and I can see it. But something is changing $PATH by the time .zshrc is called. I put an echo $PATH at the top of it and I see it has changed. So what could be changing it? Mac OS btw
