Non-negotiable rules:

1. Read the source file and its inline tests fully before moving anything.
2. Preserve the original visibility and helper access model.
3. Prefer adjacent test modules over integration tests when private access matters.
4. Change production code only as much as module wiring requires.
5. Run the narrowest relevant tests after extraction.
