Handoff toward X-C-ST

A successor receives:

1. the single map (eq:Rone) on its off-shell insertion domain;

2. its normalization, support, continuity, and tree-exactness statements;

3. the first-order identity and its explicit off-shell equation-ideal difference;

4. the bare second dressing and retained mixed term;

5. the displayed classical ${\rho }_{2,g}$;

6. the one-contraction boundary and normalization uniqueness theorem.

It does not receive a $T_2$ family, a second-order quantum dynamical map, a graviton tree, a loop triangle, a two-point response, or a sharp-width limit.
