+- **First-class caching system.** The retraction-native
+  algebra means cache invalidation is free — when the
+  underlying data retracts, dependent cache entries
+  retract with it. No TTL guessing, no cache-stampede
+  mitigation, no read-through/write-through/write-

+- **Cross-API GraphQL with automatic spill-over.** A
+  GraphQL layer over Zeta — cross-service queries
+  traverse the graph, and because events + cache are
+  retraction-native, updates propagate across API
+  boundaries automatically. No manual cache-
+  invalidation-on-mutation plumbing; no subscription-
+  pushing-over-WebSocket glue per-field. The graph is
+  live by virtue of running on Zeta.
+- **Pluggable log back-end.** Kafka, NATS, NATS
+  JetStream, and Zeta's own native log all speak to
+  the multi-node substrate. Aaron round 33: "all with
+  pluggable wire protocol, hello kafka, nats, nats
+  streaming … and our own of course." Single-node
+  consumers pick in-memory; multi-node picks whatever
+  log infrastructure they already have; greenfield
+  multi-node can pick Zeta-native and get features the
+  emulated back-ends can't express.
