Proof step 17 from proof junkref-putbar (previous step)

okbytearray(r2, st), junkref(`docs2store', r, putByteArray(bytes, r2, i + 1, st)[r2 -- i ', byteval(by)]), ∀ st, i, r2, r, bytes0. # bytes0 < # (by ' + bytes) → (junkref(`docs2store', r, putByteArray(bytes0, r2, i, st)) ∧ okbytearray(r2, st) → junkref(`docs2store', r, st)) ⊦ junkref(`docs2store', r, st)

And obtained the following new goals

Proof step 3:
⊦ ¬ is_referencevalue(val) ∧ ¬ junkref(str, r, st) ∧ okval(val, st[r1 -- _type] .type .type) → ¬ junkref(str, r, st[r1 -- i ', val])
Proof step 16:
¬ ( ¬ is_referencevalue(byteval(by)) ∧ ¬ junkref(`docs2store', r, putByteArray(bytes, r2, i + 1, st)) ∧ okval(byteval(by), (putByteArray(bytes, r2, i + 1, st)[r2 -- _type]) .type .type)), okbytearray(r2, st), junkref(`docs2store', r, putByteArray(bytes, r2, i + 1, st)[r2 -- i ', byteval(by)]), ∀ st, i, r2, r, bytes0. # bytes0 < # (by ' + bytes) → (junkref(`docs2store', r, putByteArray(bytes0, r2, i, st)) ∧ okbytearray(r2, st) → junkref(`docs2store', r, st)) ⊦ junkref(`docs2store', r, st)
