There's a next step for that.

Focused recipes, intended extension points, and a way to prove the result. Drafts below show the planned collection and its current gaps.

Create a resource

A small CRUD feature, from model and changeset to a passing request spec.

Use the same action for a browser page and an explicit JSON response.

Go from a request-scoped temporary file to a complete persistence recipe.

Connect a transaction, a typed job, and a synchronous test.

Understand the JSON input and request-policy gaps that need a supported API.

Follow the remaining gates from a local app to a supported production release.
