Proof step 9 from proof writepage-afs-cons (previous step)

err = ESUCCESS, afs-cons(dirs, files) ⊦ [choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; choose bv with true in asynced := bv; if err = ESUCCESS then {buf2 := copy(buf0, ino0, buf2, ino, n); afs_writepage#(inode, pageno, buf2, dirs; err, files; asynced)}] afs-cons(dirs, files)

Heuristic symbolic execution applied rule choose right

And obtained the following new goals
