This is not necessary, you only need to track StateMachinePath changes here. Activities and other state machines pre-date the HSM framework and won't be reflected in the oplog.

Don't panic here, return an error instead and handle it in the caller.

I'd be okay panicking if the only reason this would happen only unexpectedly. Consider making the Outputs() function panic instead of returning an error.

We can rename Outputs to OpLog.
