Proof step 2 from proof pathex-putbyteval (conclusion)

⊦ okbytearray(r2, st) ∧ ¬ junkref(`docs2store', r, st) ∧ ¬ path∃(`docs2store', r, r1, st) → ¬ path∃(`docs2store', r, r1, st[r2 -- i ', byteval(by)])

User applied rule insert lemma

And obtained the following new goals

Proof step 1:
⊦ okbytearray(r2, st) ∧ ¬ junkref(str, r, st) ∧ ¬ path∃(str, r, r1, st) → ¬ path∃(str, r, r1, st[r2 -- i ', byteval(by)])

Rule argument

[LEMMAARG : pathex-putbyteval-01, [r2, st, str, r, r1, i, by] → [r2, st, `docs2store', r, r1, i, by]]
