Module events 

UI-agnostic event emission. Consumers — desktop shells, CLI tail commands, integration tests — implement EventSink and pass it to crate::Service::build. The engine never touches a UI framework directly.

Structs

ChannelSink

Fan out via a tokio::sync::broadcast so multiple subscribers (CLI tail, tests) can observe the same stream.

ComposedSink

Trivial fan-out wrapper so an embedder can plug in more than one sink without writing a custom struct.

LogSink

Trace each event through tracing::info!. Handy default for the headless postcrate binary and for tests that just want logs.

ServerStatus

Enums

BounceKind

CoreEvent

Engine event surface. Adding a variant is a semver-minor change — consumers using Sink: EventSink only have to handle what they know.

MailboxStateChange

Traits

EventSink

Implementors receive all engine-level events.
