The trace-driven development makes sense, but I keep getting tripped up by accidentally using the wrong trace

So far, I'm really liking Dark. It's not as easy a transition from writing backends in languages like Python and Golang as I thought. The trace-driven development makes sense, but I keep getting tripped up by accidentally using the wrong trace. One other thing that I'm confused about is doing validation on the request body on a POST/PUT request. Is there a mechanism for doing that, or am I supposed to assume the request will be correct every time? It would be nice to have an example for doing request validation. Also, is there any way to update a record in a database? Or do you need to delete and then re-create it?
