📦 Final Pipeline Structure

Active Workflows (5 optimized workflows)

#	Workflow	Purpose	Triggers	Duration
1	ci-comprehensive.yml	Complete testing	PR, push to develop	~15-20 min
2	cd-development.yml	Dev builds & publish	Push to develop	~25 min
3	cd-release.yml	Production releases	Push to main, tags	~55 min
4	migration-check.yml	Migration validation	PR with model changes	~15 min
5	static.yml	Security scanning	PR, push, schedule	~5 min

🗑️ Removed Workflows

What Was Removed

Workflow	Removed	Reason
ci.yml	✅ Deleted	Fully replaced by ci-comprehensive.yml
docker-publish.yml	✅ Deleted	Fully replaced by cd-development.yml & cd-release.yml

Where Functionality Went

From ci.yml:

• Migration testing → ci-comprehensive.yml (database tests)
• Docker build testing → ci-comprehensive.yml (Docker job)
• Basic security → ci-comprehensive.yml (security tests)

From docker-publish.yml:

• Development builds → cd-development.yml
• Production builds → cd-release.yml
• Image tagging → Both CD workflows
• Multi-platform → Both CD workflows

Backups Available

Backup copies saved in:

🎯 How Workflows Trigger

Pull Request Scenario

Developer creates PR
  ↓
✅ ci-comprehensive.yml runs (always)
✅ static.yml runs (always)
✅ migration-check.yml runs (if models changed)
  ↓
Results posted to PR
  ↓
All checks must pass to merge

Development Build Scenario

Push to develop branch
  ↓
✅ ci-comprehensive.yml runs (testing)
✅ cd-development.yml runs (build & publish)
  ↓
Development image available
  ↓
Ready to deploy to dev environment

Production Release Scenario

Push to main or create tag v1.2.3
  ↓
✅ cd-release.yml runs (full pipeline)
  ↓
Full test suite passes
  ↓
Multi-platform images built
  ↓
Published to GHCR
  ↓
GitHub release created
  ↓
Production ready
