\section*{Canonical questions SFT answers}

SFT is designed to answer a fixed set of questions better than ad hoc reasoning:

\begin{itemize}[leftmargin=*]
\item \textbf{What is the correct target.} Is the intended target the full circle/torus, or does coupling force a coupled target $\mathrm{CST}_s$.
\item \textbf{Is coverage forced.} Do the symmetry-and-nondegeneracy inputs force full coverage on the correct target (globally or on an embedded subsystem).
\item \textbf{Is the witness stable.} Under the declared perturbation model, do explicit margins certify persistence of the witness.
\item \textbf{If coverage fails, why.} Which finite obstruction class occurs, and what evidence supports it.
\item \textbf{If convergence is claimed, what certifies it.} Is there a nonresonance certificate or a diffusion/mixing certificate, and what baseline and rate are justified.
\end{itemize}

The engine posture is that each question has an output: either a certificate with margins on the correct target, or a named obstruction with evidence.
