Proof step 137 from proof addarray-put-01 (previous step)

¬ (is_fskey(sk) ∧ sk ≠ _type ∧ sk ≠ _length), 0 ≤ i0 ⊦ sk = 0 ', (addarray(r, ty, 1 + i0, st)[r -- sk]) = (addarray(r, ty, val ' + mklist(initial_value(ty), i→n(i0)), st)[r -- sk])

And obtained the following new goals

Proof step 105:
⊦ (addarray(r, ty, i, st)[r -- _type]) = typeval(mkarraytype(ty))
Proof step 106:
⊦ (addarray(r, ty, vals, st)[r -- _type]) = typeval(mkarraytype(ty))
Proof step 107:
⊦ (addarray(r, ty, i, st)[r -- _length]) = intval(i)
Proof step 108:
⊦ (addarray(r, ty, vals, st)[r -- _length]) = intval(n→i(# vals))
Proof step 136:
0 ≤ i0, is_indexkey(sk) ⊦ sk = 0 ', (addarray(r, ty, 1 + i0, st)[r -- sk]) = (addarray(r, ty, val ' + mklist(initial_value(ty), i→n(i0)), st)[r -- sk]), sk = _length, sk = _type
