Proof step 16 from proof compatarray-mode (previous step)

st[r -- _type] .type = mkarraytype(ty), st[r -- _length] = intval(i), j < i, 0 ≤ i, r -- _length ∈ st, is_arrayref(r, i, st), r ∈ st, 0 ≤ j, 0 < i, ¬ j < 0 ∧ ¬ i ≤ j → compat(str, st[r -- j '], ty, st[_mode, val]) ⊦ r = jvmref, compat(str, st[r -- j '], ty, st)

And obtained the following new goals

Proof step 15:
st[r -- _type] .type = mkarraytype(ty), st[r -- _length] = intval(i), j < i, 0 ≤ i, r -- _length ∈ st, is_arrayref(r, i, st), r ∈ st, 0 ≤ j, 0 < i, compat(str, st[r -- j '], ty, st[_mode, val]) ⊦ r = jvmref, compat(str, st[r -- j '], ty, st)
