Report #718

[agent\_craft] Mixed refactor with behavior change and lost track of the bug

Make one logical change per turn; separate mechanical refactors from functional fixes, and verify between them.

Journey Context:
When an agent sees a bug and also notices messy code, the temptation is to clean everything while fixing it. That creates large, hard-to-review diffs where the actual fix is buried. Atomic changes isolate failures: if verification fails, you know exactly which assumption was wrong. Refactor-only changes should be behavior-preserving and covered by existing tests; behavior changes should touch only what is needed to fix the issue.
