The fiction I like best right now is "continuous delivery": You release often, push to production several times per day, one working branch, always ready to deploy. Features being in development are behind flags. Regression tests help a lot, eg, when you make an update or fix a bug you make an automatic test that checks if the new thing works, or repeats the steps that caused the bug and makes sure it's no longer there.
