- 룸마다 발행 권한을 가진 사회자 세션을 하나만 두고, 최신 세션이 넘겨받는다 - 밀려난 세션은 재연결해도 활성 세션을 되찾을 수 없다 - 재연결 전 옛 STOMP 연결이 늦게 끊겨도 현재 활성 세션을 유지한다 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- 이벤트 발행 시 X-Chairman-Session 헤더로 활성 사회자만 중계하고, 헤더가 없으면 거부 - 새 사회자가 공유를 시작하면 사회자 채널로 REPLACED 알림, 밀려난 세션의 발행에도 재통보 - 사회자 채널 알림에 type(SYNC_REQUEST/REPLACED)과 activeSessionId 추가 - 활성 사회자가 없는 룸에 청중이 구독하면 CHAIRMAN_ABSENT 이벤트 발행 (서버 전용) - 사회자 연결 종료 시 활성 등록 해제, 만료 기록은 기존 정리 스케줄러에서 제거 - 세션별 수신 순서 보존으로 사회자 구독이 후속 이벤트보다 먼저 처리되도록 보장 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- 사회자 토큰 유효시간을 토론 시간의 2배와 최소 3시간 중 큰 값으로 정함 - 토론 시간 합산 시 time이 비어 있는 시간 총량제 타임 박스는 팀당 시간 x 2로 계산 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough사회자 세션 식별과 단일 활성 세션 관리를 추가했습니다. 공유 요청은 세션 권한을 확인하며, 청중 구독은 룸 상태와 활성 사회자 유무에 따라 응답합니다. 토큰 만료 정책을 변경하고, 시간 총량제 합계 쿼리를 보완했습니다. Changes사회자 세션 공유

Merge Risk: 🟠 High · up to With this change, anyone who knows a room's ID can subscribe to its moderator channel without logging in. That makes them the active moderator. The real moderator's timer events are then silently dropped for up to a day, even after reconnecting with the same session. A single request can stop live sharing for an audience. The moderator channel subscription should require a valid moderator token for the room before this is merged. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

member owns the table in `handleChairmanSubscribe` before calling
`sharingService.startChairman`; reject the `/chairman/{roomId}` subscription in

- /chairman/{roomId} 구독 시 사회자 토큰과 테이블 소유 여부를 확인하고, 실패하면 구독 자체를 거부
(인증 없는 구독으로 활성 사회자를 빼앗아 라이브 공유를 중단시킬 수 있던 문제)
- 이벤트 발행은 권한을 확인한 구독으로 등록된 활성 사회자 세션만 허용하고, 발행으로는 활성 사회자가 될 수 없게 함
