So change in single header file always becomes a full build? Do you use pimpl or other tricks to avoid frequent changes to h-files, otherwise class members usually end up in the headers for simplicity and to avoid incomplete type problems on non-pointers unfortunately. Was this C or C++?

What's the difference between a clean rebuild and a scratch build?

Yes: touching any header file causes a full rebuild. Remember that ccache is "under the hood" doing memoization. So, a clean rebuild could still hit ccache, whereas a scratch build starts from an emoty ccache.
