+          thousands of times faster than any standards-compliant tracker is
+          allowed to. VIGIL's <code>PresenceEngine</code> pairs a CUSUM churn
+          trigger with an identity-agnostic presence-track confirmer and the
+          co-movement gate — an "identity-path × churn-path squeeze" that leaves
+          no safe rotation rate. First version implemented and unit-tested
+          against synthetic clone/ambient traces; field-tuning is what remains.
