T}_{\rm class}$ present in the classical action. We use $$\begin{aligned}
\label{eq:classT}
 {\cal T}_{{\rm class},\Phi_1\cdots \Phi_n}(p_1,\ldots,p_{n-1})=&
S^{(n)}_{\Phi_1\ldots
    \Phi_n}\Bigr|_{g=1}\,,\end{aligned}$$ where $S^{(n)}$ denotes the appropriate $n$-th functional derivative of the action. By setting $g=1$ in , the running coupling is taken into account via the dressing functions $z_{\Phi_1\cdots \Phi_n}^{(i)}$ in . As a consequence of our choice for $\bar Z_{\Phi_i}(p)$, the $z_{\Phi_1\ldots\Phi_n,k\equiv 0}^{(1)}(p_1,\dots,p_{n-1})$ run like appropriate powers of the strong running coupling with the momenta $p_i$ in the perturbative regime. The same holds for the RG-scale dependence of the $z_{\Phi_1\ldots \Phi_n}^{(1)}(0,\dots,0)$ at perturbative scales.

In the following we discuss in some detail the constituents of our Ansatz for the bosonised effective action of Landau-gauge QCD, which are also summarised pictorially in Fig. \[fig:truncation\]. For a more detailed description the reader is referred to App. \[app:truncation\]. The stability of this truncation and the systematic errors are discussed in App. \[app:results\_stab\].\
*Glue sector*: As a consistent scale-setting both in the perturbative and in the non-perturbative regime is crucial for our calculation, we use YM FRG data [@Fischer:2008uz; @FP] for both the gluon propagator and the ghost propagator, see Fig. \[fig:gluonprop\]. Here, we have matched our scale to the corresponding lattice scales in [@Sternbeck:2006cg] via the
