Worked on the facebook/relay repository to address a critical bug affecting client-only queries that use execution-time resolvers in observeFragmentExperimental. The solution involved removing an unnecessary hasClientEdges check and refining the handling of plural edges, which previously led to false failures and instability in client data-fetching paths. Implemented through two targeted commits, this backend and full stack development effort improved the reliability of client-side data retrieval and enhanced test stability for downstream UIs. Leveraged JavaScript, React, and GraphQL to ensure that client queries behave as expected, ultimately supporting a more robust experience for both developers and end users.
