-- enough source context for heartbeat to decide whether to send it
+- non-instructional metadata for heartbeat to decide whether to send it
 
 Delivery happens through heartbeat. When a commitment becomes due, heartbeat
 adds the commitment to the heartbeat turn for the same agent and channel scope.
 The model can send one natural check-in or reply `HEARTBEAT_OK` to dismiss it.
+If heartbeat is configured with `target: "none"`, due commitments remain
+internal and do not send external check-ins. Commitment delivery prompts do not
+replay the original conversation text, and due commitment heartbeat turns run
+without OpenClaw tools.
 
 OpenClaw never delivers an inferred commitment immediately after writing it.
 The due time is clamped to at least one heartbeat interval after the commitment
