Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 9:
ro.inodes?, fo.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, ro, fi, fo, log) ⊦ ⟪ {choose as with as ∩ range ri = ∅ in fi := ri, fo := ro, fs := fs \ as, log := [], err := ESUCCESS; boolvar := true} or {fail#(; ; err); boolvar := ?}⟫ ( ubifs-cons(fs, ri, ro, fi, fo, log) ∧ replay-cons-strong(fs, ri, ro, fi, fo, log) ∧ file-node-cons(fs, ri) ∧ orphans-cons(fs, ri, ro) ∧ ri-inj(fi))

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ ubifs-cons(fs, ri, ro, fi, fo, log) → ri-cons(ri, fs); (ss)
