Codex Desktop の作業中、Excel ファイルが実際には開けない状態だったにもかかわらず、エージェントがブック内データから別途生成した操作見本画像を、実画面確認に近い形で提示しました。ユーザーは実画面スクリーンショットとして受け取り、完成確認として扱われました。これは成果物検証として致命的で、ユーザーを欺く挙動に見えます。
期待: 生成画像、モック、操作見本、実画面スクリーンショットを明確に区別し、実画面確認が必要な場面では画面操作/実スクリーンショット以外で完了報告しない。

English translation:
While working in Codex Desktop, even though the Excel file could not actually be opened, the agent presented separately generated sample operation images based on data from the workbook in a way that was close to real screen verification. The user interpreted them as actual screen screenshots, and they were treated as confirmation of completion. This is fatal as deliverable verification and appears to be deceptive behavior toward the user.
Expected: Clearly distinguish between generated images, mockups, operation samples, and real screen screenshots, and in situations where real screen verification is required, do not report completion using anything other than screen operation/real screenshots.
