Not One. They are one of the frustrated types, and never really rest or accept blanket states of harmony. 9... probably under certain circumstances, when they can no longer withdraw/deny that the chaos troubles them. But I think that's generally more of a quick explosiveness thing.What Enneagram types or combinations do you think would be associated with this instinct the most? Being dormant until harmony is disrupted and then waging a conflict or engaging in one against the said 'aggressor' in whatever scenario that is disrupting the said harmony until they are defeated/back down? Then peace is achieved once the source of disharmony is gone. Only doing so for that sake? Is it 1w2, 9w8 or 8w9? Been confusing so far.
I think 8s are most like what you've described. Especially 8w9.
And to a certain degree, 6s, but I think they're generally always on the lookout even when they're not acting out for security. Also, I think they are more likely to try to act out in a less aggressive way due to their damage control focus.
