From looking at the later code it seems like we could just have:

struct UncheckedItem {
  has_hash: bool,
  holders: Vec<String>,
};

but it's fine the way it is now.

If dynamodb allowed deletion with just partition key we could even just have has_holders: bool...

Can you add a comment (or a type alias) that explains what a String is in this case?

Theoretically yes, at some point I even considered that. However, I wanted each UncheckedItem to be independent: to contain full information about blob, regardless if it's inside or outside a map-like collection.

Address feedback: Add type alias for blob hash, use ref instead of cloning.
