Proof step 1 from proof inv-evict (conclusion)

∀ key. key ∈ pcache → key.data? ⊦ ⟪pcache_evict#(ino; err, pcache)⟫ ∀ key. key ∈ pcache → key.data? ∧ key.ino ≠ ino

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 2:
∀ key. key ∈ pcache → key.data? ⊦ ⟪if ∀ key. key ∈ pcache → key.data? then pcache := evict(ino, pcache) else abort⟫ ∀ key. key ∈ pcache → key.data? ∧ key.ino ≠ ino

Rule argument

pos: right 1
