The greatest coordination asset is the hardest thing to amend
The invariant core works because it is not relitigated. That is also what makes it dangerous: if the premise bends, the asset becomes the liability, and by construction nobody is arguing about it.
What the theory adds. A standing convention is orphaned when it is perfectly grounded in the evidence that once justified it and has no living owner empowered to revise it. Its paper trail is impeccable — that is precisely why no audit catches it. The answer is not a weaker constitution but a named editor with a live path, and the test is blunt: propose a revision and see whether any route exists by which it could be adopted or rejected. If there is none, the core is already an artefact.
