How would we solve the challenge described in section 7 of https://arxiv.org/pdf/2309.11406 ?

Very interesting problem statement, and exciting actually that it mentions a todo list because that's task tracking which makes it relevant for our research grant! :)

First thoughts:

• need to model the data entry event separately from the real-world thing. This is related to #40
• Lenses as part of the data

To take the todo-list app,

• start with an empty distributed spreadsheet
• add a class Item
• add attributes Item#title: string, Item#completed: bool
• add a class ItemList: Item[]
• at this point, we may need to set some behaviours, or maybe just saying ItemList is an array is enough for now, will see
• add per-user State: each user has one ItemList
• add event SetCompleted of id * bool
• add event SetTitle of id * string
• add event Remove of id
• add event Add of string

Now migrate from array of objects to three separate lists. Define a Lens for that? And automatically transform the update and render functions?

I'm reading the Cambria Project paper now, this reference to Confluent is interesting!
