For the purposes of the prepack script, what is considered a "raw source"?

From Yarn's documentation, I got the impression that the prepack script will only be run when installing from "raw sources". It lists Git as an example of a raw source, but not many others; what is considered to be a raw source?

I'm trying to use prepack so that a build is invoked before publishing to our private artifactory registry, which works fine; the problem is that when I install that package from the private registry, Yarn seems to be invoking the prepack script as it reports that it "couldn't be built successfully" - presumably because it's trying to use a dev dependency package that doesn't exist at install-time (the build error log is completely empty so there's nothing to go off of there). However, I would expect that this script does not need to be called at all, as the build files have been pushed to the registry with the prepack step before the publish. Am I misusing the prepack script, or is this unexpected behavior?

Never mind, this seems to have been some sort of caching bug that resolved itself when I deleted .yarn/install-state.gz
