Looks good! Thank you! I left a couple of small comments inline. Once these are addressed, we can merge.

Also, let's update the changelog.

Oh - one other potential improvement that came to mind: maybe we should implement From<NoteDetails> for NoteFile?

If not too much of an issue we might want to test serialization as well, but it could come later.

Based on the discussion in 0xPolygonMiden/miden-client#354 (comment), I wonder if we should add NoteId variant here (and add From<NoteId> implementation).

[tomyrd]

Just read the issue discussion and had a question about this new variant. Is the idea to just serialize the NoteId? Something like NoteFile::IdOnly(NoteId)?

If that's the case, when would the rest of the information be filled in on the client? When importing or after a sync?

Yes, but I'd probably call the variant NoteId (and maybe then it makes sense to rename DetailsOnly to NoteDetails).

If that's the case, when would the rest of the information be filled in on the client? When importing or after a sync?

In this case, I'm thinking the client would make a request to the node to get the details, and if nothing comes back return an error.

Looks good! Thank you! I left a couple more small comments inline. Also, adding a simple test serialization/deserialization may be good.

Lastly, let's resolve the merge conflict for changelog.

All looks good! Thank you!
