Proof step 34:
# vols[v0] = # avols[v0], vols[v][m] = ⌜n⌝ , apebs[n, apeb][vols[v0][m0].pnum] = mkpeb(aehdr, avhdr, buf, m2, boolvar), avols[v0][m0] = mapped(apebs[vols[v0][m0].pnum].data, m1), m < # vols[v], m0 < # avols[v0], valid-ebatbl(apebs, wlar, vols, n0), v ∈ vols, v0 ∈ vols, v0 ∈ avols, apebs[vols[v0][m0].pnum].fill ≤ m1, v0 ≠ v ∨ m0 ≠ m ⊦ vols[v0][m0] = unmapped, apebs[vols[v0][m0].pnum].data = buf ∧ m2 ≤ m1
