# buf = VFS_PAGE_SIZE, afs-cons(dirs, files), pcache-cons(pcache[datakey(m, pageno), mkpentry(true, buf)], dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ files ⊦ synced(dirs, icache, pcache[datakey(m, pageno), mkpentry(true, buf)])

Heuristic use patterns applied rule weakening

And obtained the following new goals
