Running the Line

Run one well-defined task through five stations:

1. Work Order: define correct before code exists.
2. The Part: produce and approve a TDD plan, then implement test-first.
3. Andon Cord: run hard-failing gates and self-correct failures.
4. Inspection: review against the work order and judgment calls.
5. Field Returns: record leaks and push the catch upstream.

First decision: should this go on the line?

Use the line for parts: features, bug fixes, refactors with clear expected behavior, and production regressions that can become tests.

Do not force exploratory work through the line. If the user does not know what they want yet, switch to interactive exploration and produce a work order only after the shape is clear.
