…OF in CI Both observed on PR #3444 CI runs; both clear on re-run. Records the symptom, root cause (Yarn < 4.12.0 with Git >= 2.52; GitHub releases CDN drops) and the durable fix for the Yarn case.

🌐 Web query:
Electron app.getPath('logs') platform-specific locations official documentation
💡 Result:
In Electron, app.getPath('logs') returns the directory path designated for your application's log files [1]. Platform-Specific Default Locations When app.getPath('logs') is accessed (or initialized via app.setAppLogsPath), Electron assigns default locations based on the operating system [1][2]: macOS: ~/Library/Logs/[YourAppName] [2] Windows: %USERPROFILE%\AppData\Roaming[YourAppName]\logs [2][3] Linux: ~/.config/[YourAppName]/logs [2][3] Usage and Configuration By default, the path is managed by Electron. If you wish to customize the directory, you must use app.setAppLogsPath(path) [1]. Key Notes: If app.getPath('logs') is called before app.setAppLogsPath has been explicitly invoked, Electron will automatically create and point to the default directory mentioned above [1][2]. Historically, calling this method before setting the path could result in errors in older versions of Electron, but recent versions handle this by falling back to the default path [4][2]. It is standard practice in many Electron applications to use the logs path for storing process-specific logs (e.g., main.log, renderer.log) [3].

Document the app.getPath('logs') contract.
reportFilePath() stores boot-watchdog.jsonl under Electron’s platform-specific log directory. Replace the macOS-only path in AGENTS.md#L182-L184 and docs/postmortem-webview-boot-wedge.md#L201 with this contract, or scope both entries to macOS.

Use the canonical boot-wedge skill path.
skills/boot-wedge-debug/SKILL.md does not exist. Use .claude/skills/boot-wedge-debug/SKILL.md, which AGENTS.md references.
