Proof step 6 from proof inv-sync (previous step)

fo.inodes?, ro.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(fi), ri-inj(ri), ubifs-cons(fs, ri, ro, fi, fo, log), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; boolvar := err = ESUCCESS⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
