Pull request overview

Adds a clarifying inline comment in the setupWorkflowContext test helper to explain why referencing ctx.onWorkflowError inside the EventsConsumer callback is safe (the callback closes over ctx, and onWorkflowError is assigned on the same object).

Changes:

Document closure behavior for ctx.onWorkflowError usage within onUnconsumedEvent in sleep.test.ts

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Per TooTallNate's review on #1055: the setupWorkflowContext helper has a circular reference where ctx.onWorkflowError is accessed via closure before it's defined on the object. Add a clarifying comment. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
