The F trace-type failures (the $\eta$-trace hypothesis is neither confirmed nor excluded); a correct construction of $\sigma (Y)$ for $Y=K\cdot F$, $c^{\ast }\cdot G$, $\bar{c}\cdot \Phi$ (or a proof of absence); classification of $N$; the invariant evanescent operator basis and X in it; consistency with the p22 ${\kappa }^2$ evanescent counterterms.
