Additional information

After the security embargo this has failed most Windows CIs.

The first failure happened in https://github.com/nodejs/node/pull/58077 which seems to be related to the flake itself.

test/parallel/test-inspector-network-fetch.js から始め、特に 112 行目の verifyResponseReceived と、148 行目のその呼び出し元を確認してください。リンクされている Windows CI レポートを使って失敗を再現し、その後、信頼性レポートおよび PR #58077 にある関連する失敗と比較してください。Windows CI で報告された 400 応答なしにテストが安定してパスすれば完了です。
