Used simplifier rules: ⊦ ri ⊖ ∅ = ri; (s)%⊦ replay-cons-strong(fs, ri, ro, fi, fo, log) → replay-safe(log, fs, fi ⊖ fo); (ss)% ⊦ replay(log, fs, fi, fo) = replay-log(log, fs, fi ⊖ fo); (s)%⊦ replay-cons-strong(fs, ri, ro, fi, fo, log) → ( replay-cons-strong(fs0, ri0, ro0, fi0, fo0, log0) ↔ replay-safe(log, fs, fi ⊖ fo) ∧ replay(log, fs, fi, fo) = ri ⊖ ro → replay-safe(log0, fs0, fi0 ⊖ fo0) ∧ replay(log0, fs0, fi0, fo0) = ri0 ⊖ ro0); (ss)
