Proof step 2 from proof crash-neutral-check-page (previous step)

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

Heuristic symbolic execution applied rule let right

And obtained the following new goals
