Uniqueness of the normalized faithful factor trace
Projection dimension identifies any positive normalized tracial functional on a finite diffuse factor. In particular, the explicit matrix trace agrees with the canonical ultrapower trace.

Any two normalized faithful tracial states on a concrete II1 factor agree. Normality is not an extra premise.

The explicit normalized matrix trace therefore equals the canonical trace selected by the concrete factor construction.
