Worked on stabilizing the resource dependency graph in the pulumi/pulumi repository, addressing issues with transitively referenced resources. Identified and fixed a bug where an unawaited Promise in the addTransitivelyReferencedChildResourcesOfComponentResources function led to incomplete dependency graphs and misordered resource creation. The solution involved updating the Node.js backend logic to properly await all relevant Promises, ensuring resources are created in the correct order. Added regression tests using TypeScript to lock in the improved behavior and prevent future regressions. This work enhanced deployment determinism and reliability for users modeling complex resource graphs, reducing CI flakiness and deployment risk.
