Proof step 6 from proof crash-neutral-read-gnd (previous step)

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 7:
syn ↔ true, adr = adr1, adr0 = @(m, m0, m1), ginval = ginval2, ginval0 = ginval1, gstore = gstore1, gstore0 = gstore2, istore = istore1, istore0 = istore2, maxino = maxino0, remove-refsize0(gstore1) = gstore1, remove-refsize0(istore1) = istore1, elems nx ∩ ginval1 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval1, inv(gstore2 \ ginval1), inv(gstore1), inv(istore2), inv(istore1), @(m, m0, m1) ∈ gstore2, istore1 ⊑ istore2, pstate.journal? → nx ≠ [] ∧ pstate.lnum = nx.last ∧ pstate.lnum ∈ gstore2, pstate.index? → pstate.lnum ∈ istore2 ⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then gnd := gstore0[adr0] else gnd := ?⟩ true, dups(nx), m ∈ ginval1
