The version is\n  simply absent, indistinguishable from never having been published — no ghost, no\n  placeholder.\n\nNet: an agent writing one \"was this release pulled?\" check against a believed-generic\npackage-registry shape will get a false negative on at least two of these three registries,\nbecause the signal that would answer the question isn't in the field it expects (or isn't a\nfield at
