Since you have
@defmodule[picturing-programs]
then you're documenting the forms as exported by `picturing-programs'.
But you also have
(for-label racket
picturing-programs/main
picturing-programs/io-stuff
picturing-programs/tiles)
which brings some identifiers into scope with the origin
`picturing-programs/io-stuff' and `picturing-programs/tiles'.
I think you want to just remove the `picturing-programs/tiles' and
`picturing-programs/io-stuff' for-label imports, since they're covered
by `picturing-programs/main', and `picturing-programs/main' connects
with the documented source module.
