    <ul>
      <li>Maintain immutable audit logs of workflow changes, node executions, and user actions.</li>
      <li>Provide visual dashboards for workflow activity and data lineage tracking.</li>
      <li>Enable integration with enterprise SIEM tools via syslog or API.</li>
    </ul>
  </li>
  <li><strong>6.2.2: Versioning & Change Management</strong>
    <ul>
      <li>Introduce workflow versioning with the ability to rollback to prior states.</li>
      <li>Support staged promotion from development to staging and production environments.</li>
      <li>Allow export/import of workflow configurations with checksums for integrity verification.</li>
    </ul>
  </li>
  <li><strong>6.2.3: Regulatory Compliance Alignment</strong>
    <ul>
      <li>Ensure workflows adhere to GDPR, HIPAA, or industry-specific requirements when applicable.</li>
      <li>Provide configurable data retention and deletion policies for sensitive logs.</li>
      <li>Offer optional anonymization and masking features for PII during processing.</li>
    </ul>
  </li>
</ul>

<h3>Phase 6.3: Enterprise Hardening & Reliability</h3>
<p>
Prepare FlowDrop for mission-critical enterprise deployments with high availability, observability, and disaster recovery.
</p>

<h4>Tasks</h4>
<ul>
  <li><strong>6.3.1: High Availability & Failover</strong>
    <ul>
      <li>Ensure the job execution engine supports multi-server or containerized scaling.</li>
      <li>Introduce failover strategies for running workflows if a node or server goes down.</li>
      <li>Optionally integrate with Redis or database replication for queue persistence.</li>
    </ul>
  </li>
  <li><strong>6.3.2: Observability & Metrics</strong>
    <ul>
      <li>Provide Prometheus-compatible metrics for workflow performance and system health.</li>
      <li>Enable alerting on execution failures, node timeouts, or resource exhaustion.</li>
      <li>Visualize long-running workflows and bottlenecks through extended monitoring dashboards.</li>
    </ul>
  </li>
  <li><strong>6.3.3: Backup & Disaster Recovery</strong>
