Where does REAPER keep track of items offline?

[Argitoth]

Here's an item state chunk which is offline, and I don't see anything about it being offline. So where does REAPER save this information? Please don't say RAM.

It indeed seems to be stored only in RAM. Saving a project that has offlined media and then loading it back, brings the media back online. So it seems the offline state isn't serialized and deserialized. You can see this failing in the undo history too. Offlining the media is recorded as an undo entry, but the state isn't really handled correctly.

Is there some particular reason you are interested in this state data? (I think you can access it from C++ extensions by examining the PCM_source's IsAvailable() state. There's no ReaScript compatible function for that in Reaper itself.)
