# EPF6 - Week 11 ## Overview - Opened a PR on Lodestar to get feedback on the first pieces of the Kurtosis integration - Created an ad-hoc test for `KurtosisSDKRunner` to validate functionality and inspect the return structure before full Simulation integration - Began analysis of whether `NodeRoles` is necessary for reconstructing NodePair from Kurtosis services ## Main points - **Ad-Hoc Test for KurtosisSDKRunner** - Validated runner functionality outside Simulation - Inspected service outputs and confirmed actual URLs/ports being returned - Debugged initial Kurtosis integration and verified inferRoles() logic - Helped identify potential config mismatches early - **Standalone Runner Test Script** - Written to log and examine NodeService objects - Examined the shape of returned structures and their suitability for NodePair reconstruction - **NodeRoles vs NodeService** - Current hypothesis: `NodeRoles` may not be required, as role data is already redundant within ServiceContext - Future updates to `kurtosisTypes.ts` may simplify around NodeService - **Pull Request** - Opened first [Lodestar PR](https://github.com/ChainSafe/lodestar/pull/8296) on the dedicated branch `ChainSafe:feature/kurtosis-sim-tests` for the Kurtosis migration, consolidating initial work - **Next steps will depend heavily on feedback from Lodestar team review** ## Learnings & Outcomes * PR milestone represents the **first formal checkpoint** for the migration * Validation with Runner test gave clarity on what Kurtosis returns and how much of the **NodePair** interface can be recreated * Early indication that simplification is possible by relying on NodeService alone ## Week 12 TODOs * Gather team feedback on the open PR and align on migration direction * Refine or adjust approach to `NodeService / NodeRoles` based on feedback * Plan **next integration step**: adapt Simulation logic incrementally using the validated Kurtosis outputs * Continue testing **NodePair recreation** against existing assertion framework ### Useful resources checked Lodestar PR: https://github.com/ChainSafe/lodestar/pull/8296 [Lodestar contributors guideline](https://github.com/ChainSafe/lodestar/blob/unstable/CONTRIBUTING.md) [Lodestar repo: Pull request etiquette](https://github.com/ChainSafe/lodestar/blob/unstable/CONTRIBUTING.md#github-style-guide)
