[agent\_craft] Tests fail after a refactor, so the agent rewrote the tests to match the new output

Refactor code, not tests. Update tests only when the public interface changed; otherwise treat a failing test as evidence the refactor broke behavior.

Journey Context:
Changing tests to silence failures is the fastest way to ship a regression. Refactoring is defined as behavior-preserving transformations; tests are the guardrail that proves preservation. If the interface changes, update test call sites mechanically, but never relax assertions to match a buggy new result.
