Proof step 9 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) ⊦ ⟪fs[adr1] := nd, log := log + adr1 ', err := ESUCCESS; boolvar := ?⟫ (log-cons(log, fs) ∧ ri-cons(ri, fs)), adr1 ∈ fs

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 10:
