Add Auditory Hazard to the list.
Containment Protocols
I'd say you could add a few protocols to keep the item safe from possible breaches by third persons, imagine if a GOI wanted to lay their hands on this item and use it on the masses. Aside from this concern, I think the protocols have been decently written.
Description
RPC-XXX will play a variety of winter related music.
Reword to:
RPC-XXX will play a variety of music commonly associated with the winter season.
End-of-the-World
This sounds too similar to what that other wiki uses, some readers may not like that so I suggest you replace it for a different term. This is just a suggestion though.
Addendum
I assume this one is still in the drafting stage as it looks more like notes for you than an actual journal entry. I do hope you elaborate on what you mentioned in these notes. Also another suggestion that would add to the immersiveness of this entry would be to format the journal to look like handwritten pages seen in other articles.
