Proof step 21 from proof validrefs-putbar (previous step)

And obtained the following new goals

Proof step 6:
⊦ validrefs(str, refs, byte_type, st) ↔ refs = [] ∨ refs = jvmref '
Proof step 20:
okbytearray(r1, st), is_array(`docs2store', r1, putByteArray(bytes, r1, i, st)), mkarraytype(byte_type) ≤ ty, ∀ r1, st, ty, bytes, i. okbytearray(r1, st) ∧ validrefs(`docs2store', acc, ty, putByteArray(bytes, r1, i, st)) → validrefs(`docs2store', acc, ty, st), acc = [] ∨ 0 ≤ i0 ∧ i0 < st[r1 -- _length] .intval ∧ is_referencevalue(putByteArray(bytes, r1, i, st)[r1 -- i0 ']) ∧ jvmref = (putByteArray(bytes, r1, i, st)[r1 -- i0 ']) .refval ∧ acc = jvmref ' ⊦ r1 = jvmref, validrefs(`docs2store', r1 ' + acc, ty, st)
