I believe the "definition" in that circular is implicit in the labeling of
the airport operation diagrams in appendix 1. The line out from infinite
to the point where it joins the base leg is labelled "straight-in
approach"
and the narrative for point (3) labels the line from the base leg to the
runway as final.


The "final" label in that diagram is on the side of the base leg away from
the airport, indicating that final extends past the base leg. That is
consistent with the definition of final found in the Pilot/Controller
Glossary

The narrative for point 3 is, "Complete turn to final at least l/4 mile from
the runway." That does not even approach suggesting that final does not
extend beyond the base leg.
