Clean history

Keeping a clean history help take mental shortcuts. Reduces complexity.

Commit size : the smallest stable deliverable iteration possible

Helps with readability, bisect debugging, can ship to production whenever. Feature toggles help with the "deliverable" part.

Per commit automated code review

• Adds/removes behaviour: should add/remove both code+tests
• Change behaviour: same, if the changed behaviour didn't change tests, it might be best to add a test first, then change both to make the change explicit
• ISO refactor: should not modify tests (test first, lift tests up when tied to implementation...)
