- Score.submit/score/set.ts/score-inject.ts now all share one code path
- TGScore consolidated to single canonical type (was duplicated in types.ts and score.ts)
- Fixed atk/def/heal flat-vs-nested TGStats drift across leaderboard.ts, result layouts
- Fixed playedBy semantics — now correctly identifies the actual player on borrowed characters
- Attendance.allSubmitted now correctly matches against playedBy (borrower) not just userKey (owner)
- score-inject gained atk/def/heal/date/played_by parameters for full parity with real submission
- Added migrate-stats-shape.py and fix-class-keys.py maintenance scripts
