Theorem: XIV-C release

On the pair and ambiguity class frozen in J0:

1. the inherited inventory and primitive results remain valid as copied inputs;

2. the retained noncoincident characteristic configuration lies on a smooth codimension-four stratum with rank-two light-cone differentials and an explicit positive conormal relation;

3. permitted collision contacts cannot modify a neighborhood of that configuration;

4. these facts do not supply either cancellation of the complete pair or a joint characteristic prescription;

5. none of XIII-C's four successor obligations is fully discharged in this release.

The complete coefficient of $\lambda \hslash$ remains Unresolved, with the first stop at J2. No admitted ${R_1}^{(1)}$ and no universal extension obstruction are asserted.

Proof. Input statements input:XIIC, input:XIIIB, and input:branches establish the copied scope. Proposition prop:geometry, Corollary cor:positive, and Proposition prop:component establish the new diagnostic. Proposition prop:rigidity establishes contact rigidity. Theorem thm:J2 identifies exactly what those statements do and do not decide. The unentered obligations are recorded in Section sec:stop.
