I don't think that should be specified in the definition.
It shouldn't matter how you got copies, as long as you have them.
Having hashes of sources in the build instructions can be a useful implementation
approach, but I don't think those should be required either (if you have the actual
sources, there's no particular reason to require the hashes as well).

Fair point.  I think removing that word "both" is good enough.
New version of the summary motivation is:

Reproducible builds help counter unintentional errors and malicious builds.

Fair point, and it's probably unnecessary to mention either "set" or "sets".
Also, I don't think the project is developing all the tools that could be useful.
How about this as a summary description of the project?:

The reproducible builds project is developing tools and recommended
software development practices to enable all builds to be reproducible.

Again, the goal is to maximize clarity for newcomers.
