…IP components Tutorial 01 Lab/Exam: Real PointToPointChannel and PublishSubscribeChannel - P2P send/receive through real channel with handler invocation - PubSub fan-out with multiple subscribers - Multi-hop pipeline: P2P → handler enrichment → PubSub fanout - Domain objects (OrderPayload) flowing through real channels - Causation chains preserved through channel hops - Multi-stage pipeline: command in → transform → event out Tutorial 02 Lab/Exam: Real ServiceActivator wired via DI - ServiceActivator fire-and-forget invocation - ServiceActivator request-reply with ReplyTo address + causation chain - Full pipeline: P2P channel → ServiceActivator → reply channel - Named endpoints for independent pipelines - PubSub with multiple DI-wired handlers - Multi-stage DI pipeline: channel → activator → enrichment → output - Multiple independent ServiceActivators with separate endpoints Updated tutorial markdown files to match new lab/exam patterns.

…oint Replace MockEndpoint with NatsBrokerEndpoint backed by real NATS JetStream: - SetUp gets NATS URL from SharedTestAppHost, skips if unavailable - Use unique topic names with Guid to avoid cross-test contamination - Subscribe before publish with Task.Delay(500) for subscription setup - Use WaitForMessagesOnTopicAsync/WaitForMessagesAsync instead of mock SendAsync - Dispose all NatsBrokerEndpoint instances in TearDown and test bodies Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: devstress <30769729+devstress@users.noreply.github.com>
