Symbol D_rm det
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].
Its job in the formula
m det is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

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
These four terms are the treaty’s clauses. They are not decoration on the definition of ; they are the difference between a number that means something about spacetime and a number that means something about laboratory bookkeeping. A nonzero distance computed without matching all four is not evidence about worldlines. It is evidence that two different instruments were used, which is a true but uninteresting thing to discover.
