Tricky that nobody but the player themselves will know that the rule has been broken. Maybe make it a penalty that gets applied at the end of the game, instead?

It also feels like an “everyone Construct, then everyone Sabotage” check routine would be cheap enough to be a no-brainer, costing only two days of daily actions which aren’t being used for much else yet.

Although hmm, I suppose we don’t have a victory condition yet. If “points for correctly identifying the other team” turns out to be a big part of it, any kind of proof routine is going to help other players (including those in the other factions) more than the player providing the proof.

I do think that we need to have more methods of being able to guess Loyalties. But this isn’t the way to do it, I don’t think.
