Proof step 2 from proof inv-get-volume-size (previous step)

# apebs = # wlar, bflipset-cons(bflipset, wlar), unique-sqns(apebs), valid-ebatbl(apebs, wlar, vols, vtblpnum), valid-eraseq(q), valid-eraseq(wlar, q), valid-eraseq(apebs, q), valid-global-sqn(apebs, sqnum), valid-vtbl(apebs, vols, wlar, vtblpnum), valid-wl(apebs, wlar), v ∈ vols, ¬ VTBL_VOLID ∈ vols, ¬ vtblpnum ∈ q ⊦ ⟪ubi_get_volume_size#(v, vols; ; n)⟫ true

Heuristic weak unfold applied rule call right

And obtained the following new goals

Proof step 3:
# apebs = # wlar, bflipset-cons(bflipset, wlar), unique-sqns(apebs), valid-ebatbl(apebs, wlar, vols, vtblpnum), valid-eraseq(apebs, q), valid-eraseq(wlar, q), valid-eraseq(q), valid-global-sqn(apebs, sqnum), valid-vtbl(apebs, vols, wlar, vtblpnum), valid-wl(apebs, wlar), v ∈ vols ⊦ ⟪if v ∈ vols then n := # vols[v] else abort⟫ true, VTBL_VOLID ∈ vols, vtblpnum ∈ q
