Proof step 16 from proof inv-add1 (previous step)

ro.inodes?, fo.inodes?, log-cons(log, fs), node-cons(nd.key, nd), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi), ⌊err0⌋ ⊦ ⟪err := err0; adr := ?; boolvar := ?⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
