기기 시계가 서버와 어긋나 지연이 음수이거나 1초를 넘으면 보정하지 않는다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
- useAudienceSocket이 반영한 메시지의 수신 시각(latestMessageReceivedAt)을 노출한다. - useAudienceShareState가 수신 시각에서 서버 중계 이후 흐른 시간을 뺀 syncedAt을 계산해 노출한다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
- useAudienceCountdown이 syncedAt(수신값이 유효했던 시각)부터 흐른 시간을 빼고 목표 시각을 계산한다. - 실행 중 동기화할 때만 보정하고, 정지 값에서 재개하거나 기준 시각이 미래/2초 이상 지났으면 보정하지 않는다. - 기준 시각만 바뀌었을 때 진행 중인 카운트다운이 재시작되지 않도록 ref로 읽는다. - 일반/자유토론 카운트다운 모두 AudienceSharePage에서 syncedAt을 전달한다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
사회자는 남은 시간을 올림한 정수 초로 보내므로, 5초 주기 SYNC마다 청중 목표 시각이 최대 1초씩 뒤로 밀려 표시가 튀었다. 실행 중 재동기화 차이가 1초 미만이면 기존 목표 시각과 새 목표 시각 중 더 이른 쪽을 택한다. 정지 후 재생이나 1초 이상 차이는 그대로 다시 맞춘다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
다음 차례 버튼 더블클릭 시 순서가 두 번 넘어가거나, 마지막 직전 차례에서 같은 자리에 나타난 토론 종료 버튼까지 눌려 FINISHED가 발행되는 문제를 막는다. 이전/다음/종료 버튼이 500ms 대기 시간을 공유하도록 기존 useThrottle을 사용한다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Space/Enter/R 키를 길게 누르면 keydown이 반복 발생해 PLAY·STOP, TEAM_SWITCH 이벤트가 연속 발행되던 문제를 막는다. 기본 동작(스크롤 등) 차단은 유지한다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
version 순서 보장, serverTime 지연 보정, 0초 판정 주체(사회자 이벤트로 확정, 청중 로컬 처리는 표시용), 연타 방지 정책과 서버 검증을 두지 않는 이유를 정리한다. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

- Around line 10-11: Update the SocketMessage eventType union to include ERROR,
and revise the data comment so both FINISHED and ERROR are documented as
carrying null. Preserve all existing event types and payload behavior.
In `@src/apis/sockets/util.test.ts`:
- Line 381: Update the two flagged calls in the socket utility tests to match
the configured Prettier print width: format the object argument to
isSocketMessage across multiple lines and wrap the arguments to
getNetworkDelayMs across multiple lines, without changing behavior.
