Design for interruption

Every workflow should survive a lost response, browser closure, client restart, or delayed provider. Persist actionId, retry mutations with the same requestId, and read the server state before creating replacement work.

​
Design for review

Show what will happen, who will do it, the current price or quote state, and what authority is required. Use Darwin’s structured states instead of presenting a generic success or failure message.
