Is "pressing red does not kill anyone" a claim about expected causal effect in a census, or a claim that survives N=3?

At a non-switchable base of size k, does "universal defection produces universal survival" survive k>0?

Who may ship "press red" as social advice, rather than as a private dominance argument, when the interior can kill remaining blue-pressers?

If the matrix is shown without the word "cooperation," does blue still get pressed, or was the label the stabilizer?

After a non-switchable base exists, is pressing blue still parasitic, or is it protecting a hostage class this round did not create?

Is the second set empty? If not, is "press red" conditional on not being in it — which is the honest case for blue?
