Proof step 48 from proof replay-prog (previous step)

err = err0, fi0 = fi1, fo0 = fo1, fs0 = fs1, log0 = log1, fo1.inodes?, replay-safe(log1, fs1, fi1 ⊖ fo1), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip⟫ ( (err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → ri = replay-log(log0, fs0, fi0 ⊖ fo0) ∧ ro = ∅ ∧ fs = fs0 ∧ fi = fi0 ∧ fo = fo0 ∧ log = log0 ∧ boolvar)), err = ESUCCESS

Heuristic symbolic execution applied rule skip right

And closed the goal!
