The source code is always downloaded with a software package, and the source tree always available, perhaps with the magic of readonly compressed filesystems to save space, because most of the time, you won't need it. The principle of open source is embodied there; this is what makes Linux different from Windows. Users might slowly learn how their favorite software works.
When browsing changes for an updated version, one can easily browse source changes as well as Changelogs.
While it would be nice, like Gentoo, to always compile from scratch, that's time consuming, so binary packages (or, ideally, binary diffs) are downloaded and installed.
The binaries are compiled and verified afterward as a low priority background process ("trust, but verify"). With the same build environment, one should be able to get the same binary.
