| Level | Guide | You are done when |
|---|---|---|
| Junior | Definition and why | You can explain bounded parallelism. |
| Middle | How it works | You can coordinate workers, closure, and errors. |
| Senior | Failures and mistakes | You can prevent leaks and overload. |
| Professional | Best practices and scale | You can allocate end-to-end capacity. |
Practice rule: Bound work, queues, and task lifetime together.
