I'd love to review the actual content of this PR but unfortunately there's no cache. I suppose that is because the dependency tag prevented the branch from building? (though it wouldn't have passed the checks regardless)

Every positive natural number can be expressed as m^2 * n where n is square free. Used in #7274

Very minor suggestions from me, this is very nicely laid out!
Thanks for tagging me on this Eric - I do have a stronger version of this result in the unit-fractions project (giving the result that the sum up to x of prime reciprocals is log log x + b + O(1/log x)
) but it uses a bunch of stuff not yet in mathlib, and the proof idea is pretty different. So I have no objection to this version being in the archive or in mathlib!
