Code Review
This pull request introduces logging to catch blocks in src/lib/validators.ts to capture errors during URL parsing and configuration handling. The reviewer recommends reverting the logging change in isTrustedFontUrl because logging every invalid URL input can lead to log pollution and potential log-flooding vulnerabilities if the input is user-controlled.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Logging a warning for every invalid URL passed to isTrustedFontUrl can lead to log pollution and potential log-flooding vulnerabilities if the input is user-controlled. Since new URL(url) throwing an error is the standard way to detect invalid URLs in JavaScript/TypeScript, an invalid URL is an expected validation failure rather than an exceptional system warning.
It is recommended to revert this change for isTrustedFontUrl and keep the silent catch block, as returning false is the correct and fully handled outcome for invalid inputs.

インポート文の直後に空行がありません。TypeScript の一般的なスタイルガイドでは、インポートブロックと最初のコードブロック（JSDoc コメントを含む）の間に空行を入れることが推奨されています。
```suggestion
import { logger } from "./logger";
/**
* Validates a GitHub username.
```

isTrustedFontUrl の catch ブロックは new URL(url)（101行目）と new URL(allowedOrigin)（115行目）の両方で発生した例外を捕捉します。現在のログメッセージ "Invalid URL provided to isTrustedFontUrl." は url が不正であるかのように読めますが、allowedOrigin が不正な場合も同じメッセージが出力されます。どちらのパラメータが原因かをデバッグ時に把握しやすくするため、より具体的なメッセージにすると良いでしょう。

🎯 What: Updated empty catch blocks in
getTrustedFontOriginsandisTrustedFontUrlwithinsrc/lib/validators.tsto capture and log the errors using the centralizedlogger.💡 Why: Empty catch blocks hide potential issues and make debugging difficult. Logging these errors improves visibility and maintainability without altering the fallback behavior.
✅ Verification: Ensured
src/lib/logger.tsexists, verified type checking withtsc --noEmit, and confirmed all tests and lint rules pass.✨ Result: Errors during URL parsing are now explicitly logged as warnings instead of being silently ignored.

Greptile Summary
空の catch ブロックに
logger.warnを追加することで、getTrustedFontOriginsとisTrustedFontUrlでのエラーが無言で握りつぶされる問題を修正しています。フォールバック動作は変更なく、デバッグ時の可視性が向上します。getTrustedFontOrigins: 不正なAPP_URL環境変数を検出した際に警告ログを出力するよう変更。isTrustedFontUrl: URL パースに失敗した際に警告ログを出力するよう変更。ただしurlとallowedOriginのどちらが原因かはログメッセージから判断できない。Confidence Score: 4/5
空の catch ブロックにログ出力を追加するだけの変更で、フォールバック動作は維持されており、マージしても安全です。
変更内容はシンプルで影響範囲が小さく、既存のフォールバック挙動は維持されています。インポート後の空行不足とログメッセージの曖昧さという軽微なスタイル上の課題はありますが、動作上の問題はありません。
特に注意が必要なファイルはありませんが、
src/lib/validators.tsのisTrustedFontUrlcatch ブロックのログメッセージは、どちらのパラメータが問題を引き起こしたか特定できるよう改善の余地があります。Important Files Changed
