+# 005 — Election Heartbeat on Admin Transition
+
+- Area: `main.go`, `pkg/election/*`
+- Priority: Medium
+
+## Background
+Heartbeat loop starts only if this node is admin at startup. When admin changes via callback, role config is applied but no new heartbeat loop is launched. Risk: missed heartbeats post-takeover.
+
+## Scope / Deliverables
+- Start/stop admin heartbeat within the election callback based on current winner.
+- Ensure single heartbeat goroutine per admin node; cleanly stop on demotion/shutdown.
+- Log state transitions and errors.
+
+## Acceptance Criteria / Tests
+- In tests/sim, when admin role transfers, the new admin begins heartbeating within `HeartbeatTimeout/2`.
+- No duplicate heartbeats; demoted node stops sending heartbeats.
+
+## Notes
+- Consider encapsulating heartbeat management inside `ElectionManager`.
