Proof step 21 from proof initialization (previous step)

avols = ∅, err = err0, err = ESUCCESS, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ( err = ESUCCESS → ⟨ebm_avol_format#(m; ; avol0, err1)⟩ (avol0 = abs(avols[default-volid, fill(mkabstractvolume(m), erased)][default-volid]) ∧ ESUCCESS = err1)) ∧ (err ≠ ESUCCESS → (∀ avol. ⟨ebm_avol_format#(m; ; avol0, err1)⟩ (avol = avol0 ∧ err = err1)))
