And obtained the following new goals

Proof step 70:
avols[default-volid][m2] = mapped(buf1, n1), m2 < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols, n3 + n2 ≤ # buf2, m1 + n2 ≤ LEB_SIZE ⊦ ∃ buf, m. mapped(buf1, n1) = mapped(buf, m)

Used simplifier rules: elim-mapped: ⊦ leb.mapped? ↔ (∃ buf, m. leb = mapped(buf, m));%⊦ v ∈ avols ∧ m < # avols[v] ∧ avols[v][m] = mapped(buf, m0) ∧ ebm-cons(avols) → # buf = LEB_SIZE; (s)% ⊦ mapped(buf, m).data = buf; (s)% ⊦ ¬ ⌊ESUCCESS⌋ ; (s)
