Backend
- teams_data.py: 48-team data (ko/short/en), TLA→FIFA code remap
- config: schedule_all_groups, featured_group("A") — only featured group is votable/AI-predicted
- schedule_fetch: fetch all GROUP_STAGE matches from football-data, KST serialize
- schedule_sync: ingest all groups, unordered-pair match to avoid Group A dup, derive votable from group
- worker: AI generation limited to featured group; settle still covers all
- domain/predictions: is_votable() + MatchOut.votable; reject non-votable submits with 403 MATCH_NOT_VOTABLE
Frontend
- types: Match.votable
- ScheduleBoard: Naver-style date/group tabs + chips; votable(A) cards link to detail with AI split + 참여수, others display-only
Verified: 72 matches (12×6), Group A not duplicated, votable A=6/others=66; A submit 200, B submit 403
