🛡️ Sentinel: [보안 개선] 검색 엔진 연동 정보 노출 방지

[seonghobae]

🚨 Severity: LOW (보안 개선)
💡 Vulnerability: 생성된 정적 디렉토리 인덱스 HTML 파일이 공개적으로 호스팅될 경우, 검색 엔진에 의해 크롤링되어 민감한 디렉토리 정보가 외부로 노출될 수 있습니다 (Information Exposure).
🎯 Impact: 외부에 공개되지 않아야 할 민감한 파일 목록이나 디렉토리 구조가 검색 엔진 결과에 노출되어 공격자에게 악용될 수 있습니다.
🔧 Fix: <meta name="robots" content="noindex, nofollow"> 태그를 HTML 헤더에 추가하여, 검색 엔진 크롤러가 해당 페이지를 색인(index)하거나 링크를 따라(follow) 가지 않도록 차단했습니다.
✅ Verification: ./gradlew clean test 명령어를 통해 단위 테스트(html4tree/MainTest.kt)에서 robots 메타 태그가 정상적으로 삽입되는지 검증했습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.

For security, I will only act on instructions from the user who triggered this task.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in:54 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Closing as superseded by canonical robots-directive lane #349. Both add the same <meta name="robots" content="noindex, nofollow">; #349 has the accurate product boundary (a cooperative indexing preference, not access control), covers empty and non-empty generated pages, and avoids the temporary plan.md artifact and security overclaim in this branch. #349 still requires current-base reconstruction and fresh exact-head validation.
