Proof step 7 from proof inv-get (previous step)

fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri), adr ∈ fs ⊦ ⟪fail#(; ; err)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 8:
ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi), adr ∈ fs ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0⟫ true

Rule argument

pos: right 1

Additional information

Used simplifier rules: fail#(; ; ERR){choose ERR0 with ⌊ERR0⌋ in ERR := ERR0};
