Input statement: XIII-C

For the frozen full displayed coefficient and switched vertex:

1. the eleven-branch decomposition and all 48 labelled double cross-contraction matchings are inventoried;

2. ${\mathfrak{C}}_{\mathrm{tot}}$ is a subclass of the widened partial-diagonal ambiguity class ${\mathfrak{C}}_{\mathrm{part}}$;

3. elementary parallel-line distributions admit extensions with their computed scaling-degree bounds;

4. collision exclusion and the $Z_3$ sum-zero bounds do not establish the complete joint product;

5. distinct null-related vertices admit a nonzero wavefront cancellation in a retained incidence;

6. the full coefficient of $\lambda \hslash$ remains Unresolved.

These are copied results, not new extension theorems of XIV-C XIIIC.
