        <p>This blog was written in early October 2025 describing our five-component architecture. When we ran it through updated governance rules in late October 2025, the framework flagged language that violated newly-added instructions:</p>
        <ul class="list-disc ml-5 mt-2 space-y-1">
          <li><strong>inst_017 (No Absolute Assurances):</strong> Detected use of "guarantees" - now requires evidence-based language</li>
          <li><strong>inst_018 (Honest Testing Status):</strong> Flags "production-ready" claims without multi-project validation</li>
        </ul>
        <p class="mt-2"><strong>This is the framework working as designed.</strong> As governance rules evolve, they catch content that previously passed review. Rather than silently revise, we're leaving this as a live demonstration of how architectural governance improves over time. Read our <a href="/blog-post.html?slug=when-frameworks-fail-case-study" class="underline font-semibold hover:text-amber-900">framework failure case study</a> for more on transparent error handling.</p>
        <p class="mt-2 text-xs italic">Note: This blog describes early-stage research (single-project validation). The framework components exist and function, but have not been validated across multiple production deployments.</p>
