My goal here is not for Emacs to know how to indent things perfectly, it is merely to ensure that Emacs or my merge tool have not made a hash of it. Also, perhaps more importantly, it should ensure that other contributors' editors haven't made a hash of it! This is a much easier problem! > How would a library express indentation rules?

At least in Elisp, indentation rules are specified by using a "declare" form in a macro definition [1]. racket-mode for Emacs also allows a similar customization of indentation by setting properties on symbol plists, which provides something about as expressive as the DrRacket configuration dialog. A good indenter for Racket would probably need to macroexpand the source, but I imagine that something like a designated submodule could contain indentation specifications in a similar format.
