+            <p class="text-gray-700 mb-4 leading-relaxed">
+              Six months of production deployment reveals an unexpected pattern: <strong>structural constraints appear to enhance AI reliability rather than constrain it</strong>. Users report completing in one governed session what previously required 3-5 attempts with ungoverned Claude Code—achieving significantly lower error rates and higher-quality outputs under architectural governance.
+            </p>
+            <p class="text-gray-700 mb-4 leading-relaxed">
+              The mechanism appears to be <strong>prevention of degraded operating conditions</strong>: architectural boundaries stop context pressure failures, instruction drift, and pattern-based overrides before they compound into session-ending errors. By maintaining operational integrity throughout long interactions, the framework creates conditions for sustained high-quality output.
+            </p>
+            <p class="text-gray-700 leading-relaxed">
+              <strong>If this pattern holds at scale</strong>, it challenges a core assumption blocking AI safety adoption—that governance measures trade performance for safety. Instead, these findings suggest structural constraints may be a path to <em>both</em> safer <em>and</em> more capable AI systems. Statistical validation is ongoing.
