Proof step 7 from proof crash-neutral-set-iblock-refsize (previous step)

remove-refsize0(gstore1) = gstore1, remove-refsize0(istore0) = istore0, elems nx ∩ ginval1 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval1, inv(gstore2 \ ginval1), inv(gstore1), inv(istore), inv(istore0), maxino2 ∈ istore, istore0 ⊑ istore, pstate.journal? → nx ≠ [] ∧ pstate.lnum = nx.last ∧ pstate.lnum ∈ gstore2, pstate.index? → pstate.lnum ∈ istore ⊦ remove-refsize0(crash(istore, istore0)) = remove-refsize0(crash(istore[maxino2, istore[maxino2].ref-size:= n], istore0)), dups(nx)
