Q08 $F$ pieces violate only the $h\cdot h\cdot c$ row. 12 generators fail through the antifield-type piece alone, because the $\bar{c}$ partner and the $E$ channel are missing. With $\tilde{K}$: 71 of 194 nonzero $F$ images and 8 of 33 $G$ images lie in $N$, all of them also satisfying the ghost equation. The remaining failures are all in the $h\cdot h\cdot c$ row (for $G$, also in the ghost rows). A $(\lambda ,\mu )$ scan, used only as a diagnostic, shows that no single normalisation works for every generator. Failures occur with and without trace monomials, so the $\eta$-trace hypothesis is not the (sole) cause. Conclusion: on the evanescent sector of the $h\cdot h\cdot c$ row, the row operators do not compose to zero with this $\sigma$. A candidate cause is the 4D-momentum rule $T(p,\cdot )=0$ for hat components, under which $s_0\hat{h}=0$. This is OPEN.
