Proof step 4 from proof inv-sync (previous step)

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

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 5:
ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; boolvar := err = ESUCCESS⟫ true
Proof step 7:
ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi) ⊦ ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS
