The distributed-correctness lens: design or audit anything that spans machines. Use when the user designs or reviews RPC, queues, replication, consensus, sharding, fault tolerance, or distributed transactions — or asks whether a design is correct. Triggers on "is this retry safe / exactly-once / idempotency", "ordering / timestamps across servers", "is this replication safe / split-brain", "eventual vs strong consistency / CAP / CP vs AP / linearizability", "do we need consensus / Raft / Paxos / etcd / ZooKeeper", "how should I shard this / partition / shard key / consistent hashing / hot key / rebalancing", "is this fault-tolerant / failure model / graceful degradation / circuit breaker / bulkhead", "two-phase commit / 2PC / saga / compensating transaction", "distributed lock / fencing token", "leader election", "should this even be distributed". The one shift: a remote call has a THIRD outcome — succeed, fail, OR leave you NOT KNOWING which — and the first law is don't distribute until you must.
