When it comes to what we call the OT canon, I think Jesus is the Final Authority:
Luke 24 (DRA):
44 And he said to them: These are the words which I spoke to you, while I was yet with you, that all things must needs be fulfilled, which are written in the law of Moses, and in the prophets, and in the psalms, concerning me. 45 Then he opened their understanding, that they might understand the scriptures.
That canon of yours would also exclude Joshua, Judges, Ruth, Kings, Chronicles (not Samuel, which the Jews regarded as a book of David, which they counted among the Books of the Prophets), Ezra, Nehemiah, Job, and so on.
What you actually testify to is that Jesus did not include the Khetuvim when he cited the scriptures to the Pharisees, because the Pharisees did not regard the Khetuvim as authoritative at that time.
