Orchestration Statuses

I was surprised to find out there's some confusion around the possible statuses a deployed orchestration can be in, but after spending 20 minutes browsing MSDN I realised I simply couldn't find one clear description of those, so here's my attempt -

An orchestration deployed into BizTalk server can be in one of four states -

1. Unenlisted (unbound) – the process has been deployed to the server, but is unconfigured (host and/or port bindings are not set), unsubscribed and is not running.
2. Unenlisted (bound) - the process is configured, but is still unsubscribed and is not running.
3. Enlisted (stopped) – the process is fully configured, subscriptions have been created, but it is stopped.
4. Started – process is ready to run (and will do so when activated by a message)

The first two are obvious I should think, so is probably the last state, the Enlisted state however, may cause some confusion - when enlisted but stopped the orchestration's subscription is active on the message box meaning it will get evaluated for every message published. if the evaluation succeeds, the message will get queued for this orchestration but it would not start (as it is in stopped state). the messages will remain waiting until the orchestration is started or they are terminated.
