Assembles the final EMPTOR BRIEF for a purchase decision and runs its pre-flight audit: ranked pick with confidence-and-because clauses, trade-off map, evaluation matrix, sensitivity, forensics flags, trust-checked merchants, freshness stamps, and the feedback footer. Use during emptor's brief phase after evaluation completes, or standalone to re-render an existing evaluation into the brief contract. Rejects and regenerates rather than delivering an unauditable brief.
