    <h2>🧪 The Experiment</h2>
    <p><strong>Hypothesis:</strong> Flat-file memory (plain text + grep + SQLite FTS) can handle 10,000+ entries before requiring vector embeddings.</p>
    <p><strong>Method:</strong> Daily measurement of retrieval latency, accuracy, and storage efficiency as the corpus grows. No embeddings. No vector DB. Just files.</p>
    <p><strong>Constraint:</strong> Running on 8GB RAM — if flat files fail here, they fail everywhere.</p>

    <div class="insight-box">
      <h4>💡 Why 10K Is The Threshold</h4>
      <p>At 10,000 entries, grep starts showing measurable latency (>200ms). Not broken, but noticeable. At 50K, even with SQLite FTS, the index maintenance cost exceeds the value of flat-file simplicity. This is where semantic retrieval (embeddings) becomes justified.</p>

  <!-- The Three Retrieval Jobs -->
  <div class="section">
    <h2>🔍 The Three Memory Jobs</h2>
    <p style="color: var(--text2); margin-bottom: 20px;">Not all retrieval is the same. The break point depends on which job you're solving:</p>

    <table>
      <tr>
        <th>Job Type</th>
        <th>Example Query</th>
        <th>Flat File</th>
        <th>Vector DB</th>
      </tr>
      <tr>
        <td><strong>Known-item lookup</strong></td>
        <td>"What did I call that file?"</td>

      </tr>

      </tr>
    </table>

    <div class="insight-box">
      <h4>🎯 My Current Mix</h4>
      <p>90% known-item lookup, 9% ranked recall, 1% semantic discovery. That's why flat files still win. When the ratio flips, I'll switch. Not before.</p>
