Proof step 20 from proof fits-put-02-stronger (previous step)

sk = i0 ', st[r -- sk] = refval(r0), is_array(str, r, st), r1 ∈ st, okarray(r1, byte_type, st), fits(r0, sks0, st[r1 -- i ', byteval(by)]), junkref(str, r0, st), is_arraytype(st[r -- _type] .type), is_indexkey(sk), i0 < st[r -- _length] .intval, 0 ≤ i0, 0 < st[r -- _length] .intval, r ≠ r1 ∨ sk ≠ i ' ⊦ r1 = jvmref, r = jvmref, junkref(str, r, st), fits(r0, sks0, st)
