Start with the listed VS Code extension E2E workflow and the referenced GitHub Actions runs, especially the failing matrix shards and the unavailable job logs. Compare the repeated Linux and Windows occurrences with the known extension-e2eshardmatrix-windows-flaky pattern. Done means identifying a reproducible cause and making the affected E2E jobs produce reliable results or actionable failure logs.
