Proof step 6 from proof putBar-rew-01 (previous step)

putByteArray(bytes0, r, i + 1, st[r0 -- fs ', val]) = (putByteArray(bytes0, r, i + 1, st)[r0 -- fs ', val]) ⊦ (putByteArray(bytes0, r, i + 1, st[r0 -- fs ', val])[r -- i ', byteval(by)]) = (putByteArray(bytes0, r, i + 1, st)[r -- i ', byteval(by)][r0 -- fs ', val])
