        <p><strong>Hierarchy</strong>: <strong>Project</strong> flags are defaults. A mapped <strong>channel</strong> can override those defaults without changing project-wide behavior.</p>
        <p><strong>Matching modes</strong>: <code>strict</code> (prefix only), <code>balanced</code> (prefix + limited hints), <code>broad</code> (more permissive, higher false-positive risk).</p>
