J3–J5

J3 can be opened only for a distribution actually supplied by D2 or D3. The copied parallel kinetic primitive has scaling degree eight in collision codimension four. That is not a degree along the noncoincident characteristic stratum.

No uniform transverse estimate for the complete retained germ, its three- or four-vertex collision strata, or their intersections is proved here.

J4 remains closed: no characteristic distribution has been glued to the primitive partial contacts, and no overlap theorem is supplied.

J5 remains closed: inherited properness is support control for an existing distribution. It does not define (eq:retainedfull), nor does it establish a wavefront bound for its output.

No admitted degree-two coefficient and no conclusion about ${R_1}^{(1)}$ in the carrier are written.
