Proof step 15 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), ¬ junkref(`docs2store', r, putByteArray(bytes, r2, i + 1, st)) ∧ okval(byteval(by), st[r2 -- _type] .type .type)

And obtained the following new goals

Proof step 14:
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, putByteArray(bytes, r2, i + 1, st)) ∧ okbytearray(r2, st), junkref(`docs2store', r, st), ¬ junkref(`docs2store', r, putByteArray(bytes, r2, i + 1, st)) ∧ okval(byteval(by), st[r2 -- _type] .type .type)
