Proof step 8 from proof inv-sync (previous step)

remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore1), inv(gstore2 \ ginval2), ri-inj(fi1), ri-inj(fi2), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪if err0 = ESUCCESS then syn := true else syn := ?⟫ true, dups(nx)

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 9:
err0 = ESUCCESS, remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore2 \ ginval2), inv(gstore1), ri-inj(fi2), ri-inj(fi1), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪syn := true⟫ true, dups(nx)
Proof step 10:
remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore2 \ ginval2), inv(gstore1), ri-inj(fi2), ri-inj(fi1), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪syn := ?⟫ true, err0 = ESUCCESS, dups(nx)
