+    title: Matter outage 2026-08-16 was Thread mesh re-forming, not host firewall
+    decision: The 2026-08-16 Matter node outages were traced to the external Thread border
+      router's mesh re-forming (mesh prefix rotated fdfb:c653:60c7 → fd25:f6c0:5149). NOT
+      a host routing/firewall issue. Devices self-heal once the matter server re-learns
+      the new operational addresses; a per-device forced reconnect accelerates it.
+    rationale: "Evidence: all 7 nodes rotated to the new fd25 prefix between 03:28–03:36; the
+      host routed live Matter traffic fine throughout (office button session, scroll-wheel
+      button events); Thread integration shows 0 border routers and no OTBR add-on exists,
+      so routing depends on an external border router. Do not chase firewall/iptables
+      theories for this failure signature."
