We are reviewing a growing specfile library and want clearer boundaries between shared utilities, business rules, presentation, and environment-specific configuration. What structure has aged well for your team?

I am drafting a lightweight peer-review checklist covering readability, failure handling, least privilege, test evidence, logging, and rollback. What would you add or remove?

How do teams build representative test cases and compare before-and-after results while keeping the feedback loop short? Interested in process patterns rather than production details.

Our library has accumulated several generations of naming styles. Has anyone adopted a convention that captures domain, purpose, owner, and lifecycle without producing enormous filenames?

What signals tell you an automation is outgrowing a specfile and should move behind a more maintainable integration boundary? Complexity, reuse, runtime, support ownership, or risk?
