Tasks - Fused

Harnest Tasks run application-owned work outside the model tool call that requested it. Put each public @task callable under root tasks/; Harnest discovers it by filename and adds the queue runtime only when a task exists.

Need	Use
Retryable work that a tool or trusted service starts	`await task.defer(...)`
Wait for queued work from an agent invocation	Async `@tool(durable=True)`
Start work at a fixed UTC schedule	A matching declaration under `cron/`
Let managed code create or control a user’s recurring schedule	Dynamic schedules
Ordinary in-process reuse	Call the decorated task directly

Create a Task

Define, defer, inspect, cancel, and await a folder-discovered Task.

Cron schedules

Declare fixed UTC schedules in cron/.

Dynamic schedules

Create and control user-owned schedules from managed code.

Durable execution

Understand suspension, replica recovery, and the boundary between a Task and the framework run waiting for it.
