Proof step 12 from proof junkref-putbar-01 (previous step)

okbytearray(r0, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]) ⊦ junkref(str, r, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)), okval(byteval(by), st[r0 -- _type] .type .type)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 11:
okarray(r0, byte_type, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]) ⊦ junkref(str, r, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)), okval(byteval(by), st[r0 -- _type] .type .type)

Rule argument
