Use the linked guides for complete Rust service commands and explanations.

Why does a connected consumer receive nothing?	Subscription, assignment, position, and completion
Why can a message be processed twice?	Delivery, retry, and business idempotency
Why does startup fail after selecting an exporter or Proxy mode?	Build and configuration diagnosis
How do I inspect the cluster with the Rust CLI?	Admin operations
Which components own routes, replication, and storage?	Architecture overview

For a first installation, use the matched local tutorial. The current examples explicitly inject the client runtime. Do not repair a failure by copying an unrelated Java startup command, opening all firewall ports, resetting offsets, or deleting store state.
