+Per-Server Bond Topics
+----------------------

+`PR #6309 <https://github.com/ros-navigation/navigation2/pull/6309>`_ changes
+lifecycle bond heartbeats from a single shared ``bond`` topic to a per-server
+topic ``bond/<server_name>`` (for example ``bond/controller_server``).
+Both ``nav2::LifecycleNode::createBond()`` and the lifecycle manager use
+``nav2::bond_topic_name()`` so peers stay aligned when they share a namespace.
+
+This removes O(N²) DDS fan-out when many managed servers are bonded: each
+heartbeat is delivered only to the matching manager/server pair instead of to
+every Bond subscription on a shared topic.
