Proof step 2 from proof ubifs-cons-log-cons (previous step)

ubifs-cons(fs, ri, ro, fi, fo, log) ⊦ log-cons(log, fs)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
ubifs-cons(fs, ri, ro, fi, fo, log), adr ∈ log ⊦ node-cons(fs[adr].key, fs[adr])

Rule argument

Additional information

Used simplifier rules: log-cons: ⊦ log-cons(log, fs) ↔ (∀ adr. adr ∈ log → adr ∈ fs ∧ node-cons(fs[adr].key, fs[adr]));%ubifs-cons-logadr-in: ⊦ adr ∈ log ∧ ubifs-cons(fs, ri, ro, fi, fo, log) → adr ∈ fs;
