  * Heartbeat task title conventions.
  *
  * Heartbeat tasks are synthesized by the orchestrator when an agent wakes with
- * no actionable work; they carry the `[Heartbeat]` title prefix so the rest of
- * the system can detect them without a dedicated `kind` column.
- *
- * Centralizing the prefix here prevents drift between the writer (heartbeat
- * dispatch) and readers (automation, escalation, route filters).
+ * no actionable work. The `tasks.is_heartbeat` column is the authoritative
+ * flag; the `[Heartbeat]` title prefix remains only for human-readable display
+ * so existing runs, logs, and UI affordances stay stable.
