Proof step 3 from proof crash-neutral-recovery (previous step)

fi1 = fi0, ginval0 = ginval, ginval1 = ginval2, gstore1 = crash(gstore, gstore0, ginval, nx), gstore2 = gstore0, maxino = maxino0, nx0 = nx, 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), ¬ dups(nx) ⊦ ⟨index_recover#(; maxino1, nx1, ginval3, fi0, nx, maxino0, ginval2, ginval, gstore, gstore0; fi, syn, err)⟩ ( syn ∧ ginval0 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx) ∧ gstore2 = gstore0 ∧ nx0 = nx ∧ maxino = maxino0 ∧ ginval1 = ginval2 ∧ fi1 = fi0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals
