Git Workflow and Protected Main
Protected main plus pull requests and code review is the basic safety net for critical analytics code.
Mental model
Protected integration keeps critical analytical code changes reviewable and reversible.
A protected main branch blocks direct pushes and only accepts changes merged via reviewed pull requests.
Feature branches isolate work-in-progress and keep main always deployable or releasable.
Explore the mechanism
Which reviews and automated checks must complete before a change can alter the canonical branch?
- Protected main prevents unreviewed changes reaching the release line.
- Review + checks turns “I think it works” into “the system verified it”.
- When you remove gates, the risk rises non-linearly because failures compound.
What to notice
Code review is not only about style: it enforces architecture, test coverage, and shared ownership of critical modules.
Where it appears
- controlling changes to pricing libraries
- requiring peer review
- preventing unvalidated direct pushes
Where the intuition breaks
What this view leaves out
- Branch protection governs the merge path, but weak reviews or incomplete tests can still admit defects.
