# buf1 = # buf2, # buf2 = n4 + n3 + n2, avols[default-volid][m2] = mapped(buf, n1), m2 < # avols[default-volid], m2 < # abs(avols[default-volid]), ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), range=(buf1, n3 + n2, buf2, n3 + n2, n4), range=(buf1, 0, buf2, 0, n3), default-volid ∈ avols, n3 + n2 ≤ # buf2, m1 + n2 ≤ LEB_SIZE, ⌊err0⌋ ⊦ abs(avols[default-volid])[m2].mapped?

Proof step 96:
# buf2 = n4 + n3 + n2, # buf1 = # buf2, avols[default-volid][m2] = mapped(buf, n1), m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), range=(buf1, 0, buf2, 0, n3), range=(buf1, n3 + n2, buf2, n3 + n2, n4), default-volid ∈ avols, m1 + n2 ≤ LEB_SIZE, n3 + n2 ≤ # buf2, ⌊err0⌋ ⊦ ∃ buf, n. avols[default-volid][m2] = mapped(buf, n)

Additional information

Used simplifier rules: ⊦ abs(leb).mapped? ↔ (∃ buf, n. leb = mapped(buf, n)); (s)% ⊦ n < # evol → abs(evol)[n] = abs(evol[n]); (s)% ⊦ # abs(evol) = # evol; (s)
