And obtained the following new goals

Proof step 67:
avols[default-volid][m2] = mapped(buf1, n1), m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols, m1 + n2 ≤ LEB_SIZE, n3 + n2 ≤ # buf2 ⊦ ∃ buf, n. mapped(buf1, n1) = 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)
