Report #2535

[agent\_craft] Why do agent patches grow to include unrelated refactors?

Change only what is requested or clearly necessary. Don't refactor adjacent code, add new abstractions for one-time use, or sprinkle docstrings on untouched files. A bug fix should be a minimal diff; a feature should not include speculative generality.

Journey Context:
Agents sometimes 'improve' code they touch because it feels helpful, but that creates noisy diffs, review friction, and new bugs. The discipline is to treat the existing code as correct unless the task proves otherwise. If you notice a real issue outside scope, note it instead of fixing it inline. Minimal changes also make rollbacks and bisects safer.
