Input statement: XIII-C and XIII-B

XIII-C retains four obligations:

1. a joint characteristic prescription or complete-pair cancellation;

2. uniform transverse estimates at the three- and four-vertex collision strata and their intersections;

3. compatible partial contacts and singular spectators;

4. output wavefront control after proper pushforward.

Its parallel temporal kinetic primitive has collision scaling degree eight in codimension four XIIIC.

The retarded convention is

Strict full-support ordering gives zero or the scaled commutator. The selected tree datum is admitted. Properness controls a distributional pushforward after the distribution exists; it does not define a missing joint product XIIIB.
