Relator Z4-locked emergence of the massive bosons (W,Z,H) and a Z5 multi-TeV charged quartet

I extend the Relator closure program to a $\mathbb{Z}_4$-locked four-loop bouquet in the generator space $\mathbb{C}$. The resulting closure uniquely singles out $N=4$ as the next stable rung after $N=3$ and fixes a closed electroweak-scale parent mass $M_4$, while the subsequent rung $N=5$ is far heavier. Combining $M_4$ with a purely topological mixing ratio yields a parameter-free mass triad $(M_W,M_Z,M_H)$. The same locked geometry implies dominant coupling and decay channels; charged-current reconnections for $W^\pm$, neutral-current reconnections for $Z^0$, and dilation-dominant, mass-proportional couplings for the scalar radial mode. A falsifiable consequence is that sufficiently energetic collisions can expose the internal $\mathbb{C}$ structure and change the effective bouquet order, producing new resonance scales beginning at $N=5$.
