Heartbeat vs Scheduled Tasks

Use Case	Mechanism	Reason
Batch periodic checks (inbox + tasks + notifications)	Heartbeat	Consolidated checks, uses session context
Exact time ("Every Monday at 9 AM")	Scheduled task	Precise scheduling, isolated execution
One-off reminder ("Remind me in 20 minutes")	Scheduled task	No session history needed
Independent task with no chat context	Scheduled task	Clean separation from conversation

Rule of thumb: Needs conversation context → heartbeat. Needs exact time or isolation → scheduled task.
