So this chart is a little more cluttered, but I think it is more accurate, and includes, I hope, all the abilities you found.
So Taunt, Fade and Protective all work the same in that they trigger when the attacker declares an attack while engaged with a model with the ability.
Retaliate, Sanction and Inevitable all work by triggering off an attacker's ATK roll scoring zero net successes.
(Caveat: It bothers me a little that in this interpretation, Inevitable doesn't work with counterattacks, because then it seems to me that there is no reason for Stheno to have Desultory. Which makes me feel that this interpretation is wrong. But if the principle is that a counterattack only becomes an attack once it has scored successes, then I don't see any way around it.)
Envenom and Spectacle seems to both trigger off any damage from any attack.
Valor here triggers off attack damage, but only if the damage is applied to the defender, not if it is applied to the attacker.
How about Leika? We could fit Snare in here too, along with Taunt and co.
Edit: Dammit, I forgot that the abilities were supposed to be bubbles...
