Proof step 1 from proof truncate-term (conclusion)

afs-cons(dirs, files), valid-file-inode(inode, dirs, files), pageno = inode.size / VFS_PAGE_SIZE, buf-opt.none? ∨ # buf-opt.buf = VFS_PAGE_SIZE ⊦ ⟪afs_truncate#(n, pageno; buf-opt, inode, bv, err, dirs, files, asynced)⟫ true

System applied rule normalize

And obtained the following new goals
