 Diary is an app that lets you write timestamped diary entries that the frontend will show in a chronological feed. Here’s a succinct version of the app’s backend logic, which clocks in at 34 lines of code.

 The Diary frontend is a text box at the top with a list of entries generated from a list of the `/diary` shrub’s child `pith`s. Nowhere is a list of children in the state being passed from the backend to the frontend, like you might see with a Gall agent passing converting a `(list item)` to a JSON array through a mark in the event that a frontend has scried or subscribed on a path, all of which would require painstaking specification by the developer.
