Proof step 41 from proof replay-prog (previous step)

boolvar ↔ true, fo.inodes?, replay-safe(log, fs, fi ⊖ fo), err = ESUCCESS → ks0 = ∅ ∧ ro0 = ∅ ∧ ri0 = fi ⊖ fo, err = ESUCCESS ∨ ⌊err⌋ ⊦ ⟪skip⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → ri0 = replay-log(log, fs, fi ⊖ fo) ∧ ro0 = ∅ ∧ boolvar)), err = ESUCCESS

Heuristic symbolic execution applied rule skip right

And closed the goal!
