What this part means
a map from pairs of “treaty configurations” — worldline, field state, coupling type, and the gap/switching pair used to build the spectrum — to the real interval [0,1].

Where the article explains it
is a map from pairs of “treaty configurations” — worldline, field state, coupling type, and the gap/switching pair used to build the spectrum — to the real interval [0,1] ; it carries no physical units, because it is built entirely from normalized probability densities over , whose own units of inverse time cancel between numerator and denominator of every term in the integral.
The passage around this formula
Two invariances follow immediately, and one does not. does not change if a trajectory is described using a different auxiliary curve parameter before being converted to proper time — proper time itself is not a gauge choice, it is the arc length of the worldline, fixed by the metric once the trajectory and the metric are fixed, so there is…
