The model

fixture3 manages approval plumbing. The project owns meaning.

  • A fixture is an input file.
  • A suite is one approval check over fixture inputs.
  • A feature is a named group of suites, usually tied to a spec path.
  • Tags are loose suite labels for operational groups.
  • Approved output is committed reviewed behavior.
  • Received output is the latest command output.
  • Diff output is the review surface.

Features and tags do not teach fixture3 what your app does. They give agents and humans stable handles for running the right behavior slice.
