Continuous Delivery در مقابل Continuous Deployment

# GitHub Actions - build/test/stage automatically, manual approval gate before prod
jobs:
  deploy-prod:
    needs: [build, test, deploy-staging]
    environment:
      name: production   # requires manual reviewer approval
    steps:
      - run: ./deploy.sh prod

# GitHub Actions - auto-deploy to prod on every merge to main, no gate
on:
  push:
    branches: [main]
jobs:
  deploy:
    steps:
      - run: npm test
      - run: ./deploy.sh prod   # runs automatically, no approval
