• Evaluate cron expressions with per-schedule time zones
• At fire time, HTTP-call Frappe to enqueue the linked BTU Task
• Listen on Redis RPC for ping, reload, and cancel commands

Not responsible for

• Storing Task Logs (Frappe app does that)
• Desk UI

Legacy

The Rust btu_scheduler_daemon is retired. See Legacy Rust scheduler.
