Voting Correlation Matrix
Shows how similarly each pair of players votes. High agreement (green) may indicate same allegiance or one player following another.

How Detection Works
Merlin Detection
Merlin knows all evil except Mordred. We look for players who:
- Reject teams with visible evil (Morgana, Trickster, Oberon)
- Approve teams with only Mordred (blind spot)
- Show consistent "knowledge" patterns
Percival Detection
Percival sees Merlin (and Morgana appears as Merlin too). We look for players who:
- Vote similarly to the top Merlin candidate
- May trust Morgana (mistaking her for Merlin)
- Follow without knowing full evil team
Morgana Detection
Morgana may try to mimic Merlin's voting patterns. We look for evil players who:
- Have high voting correlation with Merlin suspects
- Appear to be "copying" good voting behavior
- Try to confuse Percival
