The Flag Graveyard
Decide what you would do from the brief alone. Everything below it is available, but the exercise stops working if you open it first.
The situation you were handed
Engineering manager: "Checkout had an incident because two feature flags interacted in a way nobody expected. There are dozens of flags in the service. Can you sort it out?"
The trap — the move that looks right
Banning feature flags in checkout after the incident. It removes the thing that made the incident possible and also removes staged rollouts and kill switches — the next risky change goes straight to all customers, and the next incident has no off switch.
