You can judge a lot of a system by asking a single question: how gracefully does it fail? Not whether it fails — everything does — but whether it degrades along a gentle slope or falls off a cliff.
If you can distil that into one comparable number, you can rank designs at a glance. That’s the whole seed of Rindex: take the messy, many-factored question of “how hard is this network to break?” and compress it to an index you can actually compare across chains.
