ADR-0003-cooperative-cancellation.md
ADR-0003 — Cancellation is cooperative and no thread is abandoned
type: adr status: Accepted tags: [adr]
Context
A running thread cannot be interrupted. A timeout or a losing hedged attempt can only ask the callback to stop.
Decision
Strategies hand the callback a child token (Context.withToken, Context.fork). A timeout answers TimedOut only when the callback stopped because of the timeout's own token. Hedging cancels losing attempts and joins every thread before it answers.
Consequences
- No thread outlives the call that started it.
- A callback that ignores its token delays the answer; this is documented, not hidden.
Rejected
- Walking away from a slow callback on a detached thread: leaks the thread and whatever it holds.
