Hi,
So I'm assuming you are talking about the contents of Installed-Build-Depends which is part of the .buildinfo file of the build packages output. Because I tried to check the .deb content, the UDD, the different index files of the Debian pool and also DPT, to find such a relationship but without success. Are those from the packages provided the Debian pool publicly available anywhere? Could it be some sort in the https://ftp-master.debian.org/ vault? Sorry for my curiosity, I was trying to figure out how Debian maintainers deal with packages like at random: https://tracker.debian.org/pkg/beav It seems to me that it has not been "touched" (in the broad sense) for a while: http://ftp.debian.org/debian/pool/main/b/beav/?C=M;O=A I know there are Debian CI and Reproducible which surely do a regular check. Thank you for your patience, Patrice
