Publish a finality and intervention profile

Any chain used for payments, tokenised securities, collateral or a corporate treasury should say, in one place, who can halt it, how many independent entities can coordinate a rollback, which upgrade keys and emergency multisigs exist, whether governance can freeze or redirect assets, how exchanges are expected to treat a contentious fork, and the historical record of having done any of this. The cost of reversing should be stated, not discovered.

The opportunity is not to pretend the incidents did not happen. It is to make the power legible before the next one. A buyer of settlement can then choose a chain the way they choose a custodian: by reading the intervention terms, not the adjective on the homepage.
