Is there an example template of what a properly architected git repo looks like for a Prefect project? I am having trouble conceptualizing the development workflow. I am imagining a "production" branch that at any given moment contains a portfolio of all the relevant flows for a given project. Changes (i.e. merges) to the production branch would trigger incremental registrations of the modified flows driven by some sort of backend "build" job triggered by the successful merge.Other things I am considering would be a way to have proposed changes to production flows go through automated testing before being merged to production and ideally a way for developers to test their flows in development without sullying the production environment. Bonus points for being able to code the tasks and flows in such a way so that they do not require editing between environments. is there a recognized reference architecture for such a build strategy?
