F5: prescription interface not entered

No nonzero full joint section has been established. Accordingly, F5 is not entered as a prescription construction. The following is a copied interface, not a map.

A future prescription must name:

1. its ambient graph or common-kernel space;

2. a reference distribution on a proved domain;

3. the exact characteristic locus $N$ across which it extends;

4. agreement with the reference and grouped frozen prescription;

5. a finite uniform transverse degree in stated coordinates;

6. a closed conic wavefront bound retaining off-$N$ singularities;

7. a normalization selecting one map, or a uniqueness theorem under the proved hypotheses.

The three loci ${\mathcal{N}}^{\circ }$, ${\overline{\mathcal{N}}}_{\mathrm{att}}$, and ${\tilde{\mathcal{N}}}_{\mathrm{att}}$ cannot be mixed in one degree or ambiguity statement.

The canonical product is known only on the inherited microlocally admissible domain $U_{\mathrm{can}}$. No identification

is asserted. Naming separate line distributions does not prove a reference joint distribution on that complement.

The copied wavefront requirement remains:

is a prospective bound requiring its own hypotheses. A bound by $N^{\ast }N$ alone would erase every nonsmooth off-$N$ reference point.

For a genuine codimension-four extension problem with degree at least four, smooth tangential multiples of ${\delta }^{(4)}(r)$ remain possible under the copied degree and full-conormal allowances unless a normalization or uniqueness theorem removes them. On the retained collision-free neighborhood, a nonzero such change is not a member of ${\mathfrak{C}}_{\mathrm{part}}$.

The codimension-eight common attachment intersection requires its own extension-stage analysis. No actual degree is assigned here.

Brunetti–Fredenhagen and Dang are recorded extension frameworks BF,Dang. No extension theorem from them is applied: the requisite reference distribution and uniform estimates have not been constructed.

XIII-E's frequency family is not imported as this prescription. No cutoff-and-restore limit, characteristic finite part, or new ambiguity class is introduced.
