Pull request overview
This PR hardens the generated index.html pages against unintended search-engine indexing by adding a robots meta tag in the HTML <head>, reducing risk of information exposure when directory listings are publicly hosted.
Changes:
- Add
<meta name="robots" content="noindex, nofollow">to the generated HTML<head>output. - Extend
MainTestto assert therobotsmeta tag is present in generated HTML. - Record the security learning/prevention note in
.jules/sentinel.md.

| **Vulnerability:** 공개적으로 호스팅된 디렉토리 목록이 검색 엔진에 의해 의도치 않게 인덱싱되어 정보 노출(Information Exposure)이 발생할 수 있었습니다. | ||
| **Learning:** 정적 디렉토리 인덱서가 생성하는 HTML 페이지는 배포 환경에 따라 웹에 공개될 수 있으므로, 기본적으로 검색 엔진 크롤러가 접근하거나 색인하지 않도록 방어적인 기본 설정(Secure by Default)이 필요합니다. | ||
| **Prevention:** 생성되는 HTML의 <head> 영역에 <meta name="robots" content="noindex, nofollow"> 태그를 추가하여 검색 엔진의 자동 색인을 방지하십시오. |

Closing as superseded by draft canonical #349. The same robots directive is retained there under an accurate cooperative-indexing-only boundary; it does not prevent direct access or replace server-side authorization. #349 remains blocked for post-#363 update, current Google Search Central APA 7 doctoring, changelog, generated-page tests, exact-head checks, and independent approval. No evidence from this duplicate head is reused. |
Understood. Acknowledging that this work is now obsolete as it is superseded by draft canonical #349, and I am stopping work on this task. |
💡 Vulnerability: 공개적으로 호스팅된 디렉토리 목록이 검색 엔진에 의해 의도치 않게 인덱싱되어 정보 노출(Information Exposure)이 발생할 수 있습니다.
🎯 Impact: 관리자가 의도하지 않은 민감한 디렉토리나 파일 목록이 검색 엔진 결과에 노출되어 악의적인 사용자에게 정보가 유출될 위험이 있습니다.
🔧 Fix: 생성되는 HTML의
<head>영역에<meta name="robots" content="noindex, nofollow">태그를 추가하여 검색 엔진의 자동 색인을 방지합니다.✅ Verification: 테스트 코드(
MainTest.kt)에서 해당 태그가 정상적으로 생성되는지 검증 완료했습니다.PR created automatically by Jules for task 11870708602804413794 started by @seonghobae
