Proof step 16 from proof refine-unmap (previous step)

m < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ # abs(avols[default-volid])[m, unmapped] = # abs(avols[default-volid][m, unmapped]) ∧ (∀ n. n < # abs(avols[default-volid])[m, unmapped] → abs(avols[default-volid])[m, unmapped][n] = abs(avols[default-volid][m, unmapped])[n])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
m < # avols[default-volid], n < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ abs(avols[default-volid])[m, unmapped][n] = abs(avols[default-volid][m, unmapped])[n]
