What

Complete working example app using NATS JetStream store. Full distributed deployment.

Must Demonstrate

All 3 event modeling patterns
JetStream stream with subject-per-entity
Atomic batch publish (NATS 2.12)
Distributed CommandBus via NATS queue groups
Single writer per stream across cluster
Competing projections via durable pull consumers
OCC via ExpectedLastSubjectSequence
Watch (live subscription) with catch-up
TodoList automation pattern
Multi-instance scaling: add/remove nodes dynamically
GDPR crypto-shredding
Schema evolution
HTTP API + SSE live updates

Deployment

docker-compose with 3-node NATS cluster + 3 app instances
Or connect to existing NATS

Why

This is the "full scale" example. Shows everything eskit can do with NATS.
