Proof step 16 from proof junkref-putbar-01 (previous step)

okbytearray(r0, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]), ∀ r0, st, str, r, i. okbytearray(r0, st) ∧ junkref(str, r, putByteArray(bytes0, r0, i, st)) → junkref(str, r, st) ⊦ junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ¬ is_referencevalue(val) ∧ ¬ junkref(str, r, st) ∧ okval(val, st[r1 -- _type] .type .type) → ¬ junkref(str, r, st[r1 -- i ', val])
Proof step 15:
¬ ( ¬ is_referencevalue(byteval(by)) ∧ ¬ junkref(str, r, putByteArray(bytes0, r0, i + 1, st)) ∧ okval(byteval(by), (putByteArray(bytes0, r0, i + 1, st)[r0 -- _type]) .type .type)), okbytearray(r0, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]), ∀ r0, st, str, r, i. okbytearray(r0, st) ∧ junkref(str, r, putByteArray(bytes0, r0, i, st)) → junkref(str, r, st) ⊦ junkref(str, r, st)

Rule argument
