+\subsection{Discrepancy: FPGA grade --- resolved}
+U2 was captured as \code{LFE5U-45F-8BG381I} (industrial grade, real
+$T_J$ range $-40$ to $+100^{\circ}$C) --- every other reference in
+this project (LPF, this chapter, decisions.log) uses
+\textbf{\code{LFE5U-45F-8BG381C}} (commercial grade, real $T_J$ range
+$0$ to $+85^{\circ}$C; same ``$-8$'' speed grade in both --- the
+letter suffix changes only the characterized temperature range, not
+logic speed). \textbf{User confirmed C (commercial)} is the intended
+part, consistent with every other reference --- the KiCad library
+entry needs correcting from \code{...381I} to \code{...381C}.
