ParkedOperationSaga
Sends an operator's request on a Parked entry back to the service that owns the entry: the ledger's system command of the same name (wow.ledger.Retry, Skip, MarkRecoverable, ApplyRetrySpec), to the command topic of the context that holds the entry (ParkedState.context), addressed to the entry (Ledger.targetOf). The owning service takes it because this saga of the ops context sent it (the operator was authorized here, and keeps being the command's), runs it on its ledger, and publishes the entry as it then stands, which comes back as a record.
A command the owning service refuses comes back as its rejection's receipt (onActionRejected), which the entry records as RecordActionRefused, so the console shows why the operator's request came to nothing. Taking the receipts is also what makes each command carry this context as its source.
Functions
The owning service refused a command this saga sent for the entry: the entry records the refusal.
