Proof step 5 from proof inv-store (previous step)

gstore[adr] = mkgnode(nd, m, boolvar, boolvar0), remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore \ ginval), inv(gstore0), key-cons(key, nd), ri-inj(fi), ri-inj(fi0), adr ∈ gstore, ¬ dups(nx), ¬ adr ∈ fi ⊦ ⟪index_index_store#(key, adr, fi0, ginval, gstore, gstore0, nx, maxino, ginval0, syn; adr0, syn0, fi)⟫ ri-inj(fi)

And obtained the following new goals

Proof step 6:
syn0 ↔ syn2, syn ↔ syn1, gstore2[adr2] = mkgnode(nd, m, boolvar, boolvar0), adr = adr1, adr0 = adr2, ginval = ginval1, ginval0 = ginval2, gstore = gstore1, gstore0 = gstore2, remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore1), inv(gstore2 \ ginval2), key-cons(key, nd), ri-inj(fi0), ri-inj(fi), adr2 ∈ gstore2 ⊦ ⟪if ¬ adr0 ∈ fi ∧ adr0 ∈ gstore0 ∧ key-cons(key, gstore0[adr0].nd) then {syn := key ∈ fi; if syn then adr := fi[key] else adr := ?; fi[key] := adr0} else abort⟫ ri-inj(fi), dups(nx), adr2 ∈ fi
