\title{Placeholder Vignette: Source-Scan Violation}

\Abstract{
  This vignette triggers \code{JSS-SRC-001} by containing a single line
  that overflows the 80-column default. The \code{eval-jss} harness uses
  this to exercise the raw-source-scan rule code path end to end.

\section{Introduction}

See \cite{smith2020} for background on this method and an overly long subsection heading below that intentionally exceeds the eighty column default width for JSS source-scan rules.
