Proof step 6 from proof crash-neutral-contains (previous step)

remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval1 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval1, inv(gstore1), inv(gstore2 \ ginval1), ri-inj(fi1), ri-inj(fi2) ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then syn := key ∈ fi2 else syn := ?⟩ true, dups(nx)

Heuristic symbolic execution applied rule choose right

And obtained the following new goals
