+          <p>
+            Spread tiers above run inside the <strong>triple onion</strong> orchestrator: recon (<code>vuln_recon</code>,
+            service probes) → policy gates (<code>patch_first</code>, risk score) → deploy lanes → mining execution.
+            Server-side <strong>adaptive strategy</strong>, <strong>phenotype cloning</strong>, and <strong>failure atlas</strong>
+            adjust mining tier order and skips; <strong>Fleet AI Control</strong> (Calibrate) can override adaptive when enabled.
+            Crucible <strong>Access Depth</strong> and <strong>LOTL Timeline</strong> show live progression.
