Proof step 2 from proof valid-sqns-extract-sqn-h (previous step)

n < m0, valid-peb(v, m, apebs[n]), m0 ≤ # apebs ⊦ ∃ bag. valid-sqns(v, m, apebs, m0) = bag ++ apebs[n].vidhdr.sqn

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
n < m0, n < # apebs, valid-peb(v, m, apebs[n]), m0 ≤ # apebs ⊦ ∃ bag. valid-sqns(v, m, apebs, m0) = bag ++ apebs[n].vidhdr.sqn

Rule argument
