This instance's identity, stamped on every published frame.

Must be unique per replica; runtime.uuid() is what the plugin passes.

The Durable Object binding name, used only in error messages.

The object name every replica shares, from idFromName.

Two applications sharing one namespace must use different topics, or each receives the other's frames.

Logger accessor for reporting a transport failure.

A thunk, never a captured value: the kernel answers ctx.logger as undefined until a logger is registered, and a logger may be registered imperatively after this plugin's register() runs. Capturing the value would silence every report for that application.
