+    title: tplink/Kasa entries are discovery-based; IP changes handled automatically
+    decision: "tplink/Kasa entries are discovery-based (not IP-bound): if a plug's IP changes,
+      HA re-discovers it automatically; no re-pairing needed and fixed IPs are not
+      required. Do not re-pair or pin IPs in response to an IP change."
+    rationale: User asked whether IP changes would break the tplink integration. The config
+      entry (01M182SQ9M0SJDN9DTXTCG2QZA) is source 'user' with no IP pinned; HA 2024.1+
+      python-kasa discovery rebroadcasts handle IP changes. Brief 'unavailable' window is
+      normal and self-healing; a DHCP reservation is optional.
