Command chat is a runnable demonstration of topic broadcast in the gateway package: a room-based WebSocket chat where every message a client sends is fanned out to every other client in the same room via Registry.Broadcast, and WithExclude keeps the sender from getting an echo of its own line back.

Command cluster is a runnable demonstration of the reason this package exists: a connection can be registered on one node and receive a message handed to a completely different node.

Command delivery-confirm is a runnable, single-process demonstration of gateway.WithDeliveryConfirmation: the opt-in that turns cross-node delivery from a fire-and-forget actor.Tell into an actor.Ask that waits for the connection-owning node to acknowledge the socket write.

Command echo is a minimal, runnable demonstration of the gateway package:

Command graphql-ws demonstrates that gateway.Registry is usable without gateway.WSHandler at all.

Command notification is a minimal, runnable version of the "multi-device group push with offline fallback" pattern every notification-style consumer of gateway needs:

Command offline-push demonstrates Registry.WithOfflineChannel: the library-native replacement for the old pattern where every caller of SendToGroup had to inspect DeliveryResult.None itself and remember to invoke its own offline transport (see examples/notification, which still shows that manual style for comparison).

Command persistence is a minimal, runnable version of gateway's opt-in at-least-once delivery: a gateway.Outbox plus Registry.Ack turning the default fire-and-forget socket write into "persist, deliver, wait for the client's ack, redeliver on reconnect if it never came".

Command presence-watch is a minimal, runnable version of the "friend came online" pattern: a watcher subscribes once to a group's membership changes with Registry.WatchPresence and receives a PresenceJoin/PresenceLeave event the instant a connection registers or unregisters for that group, instead of polling Registry.GroupMembers or Registry.IsOnline on a timer.

Command reauth-kick is a minimal, runnable version of the "authorization can be revoked out from under a live socket" pattern: a WebSocket handshake only proves who the caller was at connect time, not who they still are five minutes into a long-lived session.

Command sse-resume is a minimal, runnable demonstration of Last-Event-ID replay.

Command tls-cloudflare demonstrates gateway.Manager wired for the two TLS shapes described in README.md:
