Certified Development Lifecycle and Deployment Designer

A sound Salesforce source-control model uses a centralized repository with branches that isolate project work and concurrent release streams, including minor and major releases. The master/main branch should be the single controlled representation of what is deployed to production, preventing ungoverned production paths and keeping the release baseline traceable. Salesforce guidance describes a main branch containing the production-deployed code, with UAT and feature branches above it, and identifies source control as the centralized source of truth. Separate release streams avoid intermixing changes intended for different release cadences.
