The three Part~V results---positive regularity (III.T25), the Yang--Mills gap (III.T27), and NF-addressability (III.T28)---are instances of Mutual Determination (Definition~\ref{def:mutual-determination-schema}) at enrichment level~$E_1$, with the following unified structure:

\textbf{Problem} & \textbf{Boundary Data ($B$)} & \textbf{Spectral Structure ($S$)} & \textbf{Interior Consequence ($I$)} \\
\midrule
NS & $\tau$-admissible fluid data & Defect contractivity & Stabilized $\omega$-germ \\
 & (Def.~\ref{def:tau-admissible-fluid-data}) & $\Delta(f,n) \to 0$ & (regularity) \\
\addlinespace
YM & $\tau$-admissible gauge data & NF discreteness & Spectral gap \\
 & (Def.~\ref{def:tau-admissible-gauge-data}) & $|\operatorname{NF}| \le \operatorname{Prim}(k)$ & $\Gamma^*_s > 0$ \\
\addlinespace
Hodge & $\sigma$-fixed characters & Balanced $B/C$ content & NF-addressable \\
 & (Def.~\ref{def:sigma-fixed-character}) & $\chi_+ / \chi_-$ equilibrium & in all sectors \\

\noindent In each case, the boundary data uniquely determines the spectral structure, which uniquely determines the interior consequence. The bidirectional passage $B \leftrightarrow S \leftrightarrow I$ closes because the interior consequence reconstructs the boundary data via the primorial tower maps.
