Proof step 5 from proof crash-neutral-read-gnd (previous step)

remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore \ ginval), inv(gstore0), ri-inj(fi), ri-inj(fi0), @(m, m0, m1) ∈ gstore, ¬ dups(nx), ¬ m ∈ ginval ⊦ ⟨index_read_gnd#(@(m, m0, m1), fi, fi0, ginval, gstore, gstore0, nx, maxino0, ginval2, true; gnd; err)⟩ true

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
syn ↔ true, adr = @(m, m0, m1), fi = fi1, fi0 = fi2, ginval = ginval2, ginval0 = ginval1, gstore = gstore1, gstore0 = gstore2, maxino = maxino0, 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), @(m, m0, m1) ∈ gstore2 ⊦ ⟨if adr ∈ gstore0 ∧ ¬ adr.lnum ∈ ginval0 then {fail_or_success#(; ; err); if err = ESUCCESS then gnd := gstore0[adr] else gnd := ?} else abort⟩ true, dups(nx), m ∈ ginval1
