Covers how to create Workers, schedule jobs using the execute() method, and understand the producer/job/Future pattern. Explains KN's two fundamental concurrency rules — live state belongs to one thread, frozen state can be shared — and demonstrates through code examples why passing mutable state between threads is intentionally difficult. Also covers object detachment, reference counting (vs garbage collection), and the freeze() approach as the practical solution for sharing data across threads. Part 1 of a series, with future episodes planned on state rules, freezing, and coroutines integration. ## Full article daily.dev links to this article rather than hosting it.
