Guranteed to be in the chksum data; iow, when manifest2 is switched over to fully all manifest1/digest data becomes effectively invisible to portage and is filtered out on commits. So... what's guranteed in manifest2 now is just sha1. In reality, it holds size/sha1/sha256/rmd160 per file entry. ~harring
