This causes builds to break without any obvious change, and worse, can be caused by a transitive dependency that the build author has no control over.

To achieve https://reproducible-builds.org/[reproducible builds], it is necessary to _lock_ versions of dependencies and transitive dependencies such that a build with the same inputs will always resolve the same module versions.
This is called _dependency locking_.

It enables, amongst others, the following scenarios:
