// full-sweep-admin.spec.ts — 관리자 콘솔(admin) 전수 점검 신규 스펙.
// docs/ops/e2e-full-sweep-2026-07-27.md §7 "관리자 콘솔 (admin)"에서
// "검증: 신규 spec 필요"로 표기된 체크리스트 항목을 검증한다.
// UI 상태 고정(가드·로딩·오류·정렬·필터 파라미터)은 page.route fixture로,
// 서버 왕복이 필요한 항목(보류/소속·코호트 저장/티켓 처리·해제)은 실 API로 검증한다.
// AI 엔진 턴 생성은 어디에서도 수행하지 않는다.
//
// 이 스위프에서 발견된 앱 결함 2건:
// 1) [프리즈] usersData=null(users API 실패) 상태 또는 실 DB 스케일의 티켓 검색 입력에서
//    TanStack Table _autoResetPageIndex ↔ React setState 무한 마이크로태스크 루프로
//    관리자 콘솔 렌더러가 영구 프리즈된다. → test.fixme 재현 테스트 2건으로 격리.
// 2) [코호트 유실] 서버(POST/PATCH /admin/users)가 cohort_ids 배열의 첫 항목만 저장한다.
//    → "persists every comma-separated cohort id" 테스트가 의도적 RED.
