Proof step 33 from proof replay-prog (previous step)

ri = replay-log(log, fs, fi ⊖ fo), ro = ∅, fo.inodes?, replay-safe(log, fs, fi ⊖ fo) ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; boolvar := err = ESUCCESS⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → boolvar))

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 34:
ri = replay-log(log, fs, fi ⊖ fo), ro = ∅, fo.inodes?, replay-safe(log, fs, fi ⊖ fo), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; boolvar := err = ESUCCESS⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → boolvar))
Proof step 36:
ri = replay-log(log, fs, fi ⊖ fo), ro = ∅, fo.inodes?, replay-safe(log, fs, fi ⊖ fo) ⊦ ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS
