unconfirmed is the state of a series the client stopped watching before it
could see the end. It is not a failure: the PACS keeps pushing and CUBE keeps
registering after a watch ends, so the retrieve is very likely still running
or already done. Reporting such a series as error claims knowledge the
client does not have, and a caller that treats it as failure will tell an
operator that nothing arrived while the files land behind them.
Lifecycle states of one series retrieve.
