Proof step 3 from proof crash-neutral-check-page (previous step)

boolvar ↔ boolvar1, boolvar0 ↔ boolvar2, key = datakey(ino, pageno) ⊦ ⟨if key ∈ pcache then {boolvar0 := true; boolvar := pcache[key].dirty} else boolvar0 := false⟩ true

Heuristic conditional right split applied rule if right

And obtained the following new goals
