Term	Kind	Topic	What it is
Admission Control	practice	Load Shedding	Deciding at the entrance whether to accept a request at all, based on whether the system can complete it within its deadline.
Graceful Degradation	practice	Distributed Systems	Continuing to deliver reduced but useful function when a dependency fails, instead of failing the whole request.
Idempotency Key Scoping Key Scope, Deduplication Scope	practice	Idempotency	The decision of what an idempotency key is unique within, what is stored alongside it, and how long it lives - the three choices that determine whether deduplication actually works.
Progress-Based Liveness Are-You-Making-Progress Check, Beyond Heartbeats	practice	Leader Election	Detecting a leader or worker that is alive but not advancing, by checking whether work is progressing rather than whether the process responds.
