"""tests/lifecycle_guards/test_gemini_image_severity.py — task-2471 회귀 테스트.

토르가 commit 0750481e 에서 ``scripts/gemini_severity_parser.py`` 에 추가한
이미지 alt-text severity 패턴 (``![High](url)`` / ``![Critical](...)`` /
``![Blocking](...)``) 을 영구 차단한다.

- ``_HIGH_IMAGE_LABEL`` 정규식 노출
- ``count_severities`` 가 image hits 를 high 카운트에 반영
- 대소문자 무관 (``re.IGNORECASE``)
- code block 안의 ``![High]`` 는 strip (false positive 방지)
- ``match_high_severity`` 도 image label 인식

헤임달(개발2팀 테스터) 작성.
