walkSourceFiles now lists each indexed folder (src, e2e, prisma) once per worker and filters it by prefix, readSource and readSourceFolder read through the same memoised file cache, and readSourceText is the cached read for guards that read files themselves. The guards project shares a module graph per worker, so a file is read once however many guards ask for it. sourcesContaining adds the substring pre-filter for sweeps that look for a few markers. Every guard over 1.5 s now reads through it; anything outside the indexed folders is read from disk as before.
