Proof step 8 from proof inv-lookup (previous step)

fo.inodes?, ro.inodes?, log-cons(log, fs), ri-cons(ri, fs), ri-inj(fi), ri-inj(ri), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; if err = ESUCCESS then {boolvar := key ∈ ri; if boolvar then nd := fs[ri[key]] else nd := ?} else boolvar := ?, nd := ?⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
