Proof step 3 from proof crash-neutral-erase (previous step)

m < # avols[v], ebm-cons(avols0), ebm-cons(avols), v ∈ avols, avols ⊆ avols0 ⊦ ⟨ebm_erase#(v, m; avols; err)⟩ (avols ⊆ avols0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 4:
m < # avols[v], ebm-cons(avols), ebm-cons(avols0), v ∈ avols, avols ⊆ avols0 ⊦ ⟨if v ∈ avols ∧ m < # avols[v] then {fail_or_success#(; ; err); if err = ESUCCESS then avols[v][m] := erased else {skip or avols[v][m] := unmapped}} else abort⟩ (avols ⊆ avols0)

Rule argument

pos: right 1
