+# GitHub Actions CI/CD Documentation
+
+## Overview
+
+This document describes the GitHub Actions CI/CD pipeline for the Tercul backend
+project, updated to 2025 best practices. The pipeline ensures code quality,
+security, and reliable deployments through automated testing, linting, security
+scanning, and containerized deployments.
+
+### Quick Reference
+
+| Workflow | File | Purpose | Triggers |
+|----------|------|---------|----------|
+| **Lint** | `lint.yml` | Code quality & style | Push/PR to main, develop |
+| **Test** | `test.yml` | Unit tests & compatibility | Push/PR to main, develop |
+| **Build** | `build.yml` | Binary compilation | Push/PR to main, develop |
+| **Security** | `security.yml` | CodeQL scanning | Push/PR to main + Weekly |
+| **Docker Build** | `docker-build.yml` | Container images | Push to main, Tags, PRs |
+| **Deploy** | `deploy.yml` | Production deployment | Tags (v*), Manual |
+
+## Architecture
+
+The CI/CD pipeline follows the **Single Responsibility Principle** with focused workflows:
+
+1. **Lint** (`lint.yml`) - Code quality and style enforcement
+2. **Test** (`test.yml`) - Unit tests and compatibility matrix
+3. **Build** (`build.yml`) - Binary compilation and verification
+4. **Security** (`security.yml`) - CodeQL security scanning
+5. **Docker Build** (`docker-build.yml`) - Container image building and publishing
+6. **Deploy** (`deploy.yml`) - Production deployment orchestration
+
+## Workflows
+
+### Lint Workflow (`lint.yml`)
+
+**Purpose**: Ensures code quality and consistent style across the codebase.
+
+**Triggers**:
+
+- Push to `main` and `develop` branches
+- Pull requests targeting `main` and `develop` branches
+
+**Jobs**:
+
+- `golangci-lint`: Go linting with golangci-lint
+  - Checkout code
+  - Setup Go 1.25 with caching
+  - Install dependencies
+  - Tidy modules (ensures go.mod/go.sum are clean)
+  - Run linter with 5-minute timeout
+
+**Configuration**:
+
+- **Timeout**: 5 minutes
+- **Target**: All Go files (`./...`)
+- **Cache**: Enabled for faster runs
+
+### Test Workflow (`test.yml`)
+
+**Purpose**: Validates code functionality through comprehensive testing.
+
+**Triggers**:
+
+- Push to `main` and `develop` branches
+- Pull requests targeting `main` and `develop` branches
+
+**Jobs**:
+
+#### Unit Tests
+
+- **Environment**: Ubuntu with PostgreSQL 15 and Redis 7
+- **Features**:
+
+  - Race detection enabled
+  - Code coverage reporting (atomic mode)
+  - HTML coverage report generation
+  - Test result summaries in GitHub UI
+  - 30-day artifact retention
+
+**Services**:
+
+- PostgreSQL 15 with health checks
+- Redis 7-alpine with health checks
+
+#### Compatibility Matrix
+
+- **Trigger**: Push to `main` branch only
+- **Strategy**: Tests across Go versions 1.22, 1.23, 1.24, 1.25
+- **Purpose**: Ensures compatibility with multiple Go versions
+- **Fail-fast**: Disabled (all versions tested even if one fails)
+
+### Build Workflow (`build.yml`)
+
+**Purpose**: Compiles the application binary and validates the build.
+
+**Triggers**:
+
+- Push to `main` and `develop` branches
+- Pull requests targeting `main` and `develop` branches
+
+**Jobs**:
+
+- `build-binary`: Binary compilation and verification
+  - Dependency verification with `go mod verify`
+  - Build to `bin/tercul-backend`
+  - Binary validation test
+  - Artifact upload (30-day retention)
+
+**Permissions**:
+
+- `contents: read` - Read repository code
+- `attestations: write` - Future SLSA attestation support
+- `id-token: write` - OIDC token for attestations
+
+### Security Workflow (`security.yml`)
+
+**Purpose**: Automated security vulnerability detection with CodeQL.
+
+**Triggers**:
+
+- Push to `main` branch
+- Pull requests targeting `main` branch
+- Scheduled: Every Monday at 14:20 UTC
+
+**Jobs**:
+
+- `codeql-analysis`: CodeQL security scanning for Go
+  - Setup Go 1.25 (must run before CodeQL init)
+  - Initialize CodeQL with Go language support
+  - Build code for analysis
+  - Perform security scan
+  - Category: "backend-security" for tracking
+  - Continues on error (warns if code scanning not enabled)
+
+**Important Notes**:
+
+- **Go Setup Order**: Go must be set up BEFORE CodeQL initialization to ensure version compatibility
+- **Code Scanning**: Must be enabled in repository settings (Settings > Security > Code scanning)
+- **Error Handling**: Workflow continues on CodeQL errors to allow scanning even if upload fails
+
+**CodeQL Configuration**:
+
+The workflow can be customized with additional query suites:
+
+```yaml
+- name: Initialize CodeQL
+  uses: github/codeql-action/init@v3
+  with:
+    languages: go
+    # Run security-extended suite for more comprehensive scanning
+    queries: security-extended
+    # Or use security-and-quality for maintainability checks
+    # queries: security-and-quality
+```
+
+**Available Query Suites**:
+
+- `security-extended`: Default queries plus lower severity/precision queries
+- `security-and-quality`: Security queries plus maintainability and reliability
+
+**Custom Query Packs**:
+
+Add custom CodeQL query packs for specialized analysis:
+
+```yaml
+- name: Initialize CodeQL
+  uses: github/codeql-action/init@v3
+  with:
+    languages: go
+    packs: my-org/go-security-queries@1.0.0
+```
+
+### Docker Build Workflow (`docker-build.yml`)
+
+**Purpose**: Builds and publishes multi-architecture Docker images.
+
+**Triggers**:
+
+- Push to `main` branch
+- Tag pushes with `v*` pattern
+- Pull requests targeting `main` branch
+
+**Jobs**:
+
+- `build-image`: Multi-platform Docker image building
+
+  - Docker Buildx setup for multi-arch builds
+  - Login to GitHub Container Registry
+  - Metadata extraction for tags and labels
+  - Build for AMD64 and ARM64 architectures
+  - Push to registry (except for PRs)
+  - Generate build provenance attestation
+
+**Image Tagging Strategy**:
+
+- `main` branch pushes → `main` + `sha-<hash>` tags
+- Tag pushes (`v1.2.3`) → `v1.2.3`, `1.2.3`, `1.2`, `sha-<hash>` tags
+- Pull requests → `pr-<number>` tag (build only, not pushed)
+
+**Push Behavior**:
+
+- **Pushes to main/tags**: Build and push to registry
+- **Pull requests**: Build only (validation, no push)
+
+**Platforms**: linux/amd64, linux/arm64
+
+### Deploy Workflow (`deploy.yml`)
+
+**Purpose**: Production deployment orchestration to Docker Swarm.
+
+**Triggers**:
+
+- Tag pushes with `v*` pattern
+- Manual dispatch with version input
+
+**Jobs**:
+
+- `deploy-production`: Deployment to production environment
+
+  - Version extraction from tag or manual input
+  - Docker Swarm service update (SSH-based deployment template)
+  - Deployment summary with timestamp
+  - Environment protection and tracking
+
+**Environment**:
+
+- Name: `production`
+- URL: Configurable production URL
+- Protection: Supports required reviewers and wait timers
+
+**Manual Deployment**:
+
+Deployments can be triggered manually from the Actions tab with a specific version.
+
+**Required Secrets**:
+
+- `SWARM_HOST`: Docker Swarm manager hostname/IP
+- `SWARM_SSH_KEY`: SSH private key for Swarm access
+
+## Workflow Execution Order
+
+**On Pull Request**:
+
+1. Lint → Validates code style
+2. Test → Runs unit tests with coverage
+3. Build → Compiles binary
+4. Security → CodeQL analysis (main branch PRs only)
+5. Docker Build → Builds image (no push)
+
+**On Push to main**:
+
+1. Lint → Code quality check
+2. Test → Unit tests + compatibility matrix
+3. Build → Binary compilation
+4. Security → CodeQL scan
+5. Docker Build → Build and push image
+
+**On Tag Push (v\*)**:
+
+1. Docker Build → Build and push versioned image
+2. Deploy → Deploy to production
+
+## Security Features
+
+### Permissions Management
+
+- **Principle of Least Privilege**: Each workflow has minimal required permissions
+- **GITHUB_TOKEN Restrictions**: Read-only by default, elevated only when necessary
+- **Workflow Separation**: Each workflow operates independently
+- **Attestation Permissions**: For build provenance and SLSA compliance
+
+### Code Security
+
+- **CodeQL Integration**: Automated security scanning for Go code
+- **Dependency Verification**: `go mod verify` ensures integrity
+- **Module Tidying**: `go mod tidy` prevents dependency drift
+
+### Container Security
+
+- **Multi-platform Builds**: Ensures compatibility and security across architectures
+- **Provenance Attestation**: Cryptographic proof of build integrity
+- **Registry Security**: GitHub Container Registry with token-based authentication
+
+### Secrets Management
+
+- **No Hardcoded Secrets**: All sensitive data uses GitHub secrets
+- **Environment Variables**: Proper isolation of configuration
+- **GITHUB_TOKEN**: Automatic authentication for package registries
+- **Granular Permissions**: Package-level access control
+
+### Package Registry Security
+
+- **GITHUB_TOKEN Authentication**: No personal access tokens required
+- **Automatic Permissions**: Packages inherit repository visibility
+- **Repository Scoped**: Packages linked to source repository
+- **Granular Access**: Fine-grained permissions per package
+- **Artifact Attestation**: Cryptographic proof of build provenance
+- **OIDC Support**: Token-based authentication without long-lived credentials
+
+## Best Practices Implemented
+
+### 2025 Updates

+
+### Troubleshooting
+
+#### Common Issues
+
+1. **Cache Misses**: Clear caches if corruption suspected
+2. **Service Failures**: Check health check configurations
+3. **Permission Errors**: Verify GITHUB_TOKEN scopes
+4. **Timeout Issues**: Adjust timeout values in workflow configurations
+5. **Docker Push Failures**: Check package write permissions
+6. **Registry Authentication**: Ensure `packages: write` permission is set
+
+#### Package Registry Issues
+
+**Problem**: Cannot push to GitHub Container Registry
+
+```yaml
+# Solution: Ensure proper permissions
+permissions:
+  contents: read
+  packages: write
+  id-token: write
+  attestations: write
+```
+
+**Problem**: Package not visible after push
+
+- Check package visibility settings (public/private/internal)
+- Verify repository is linked to package
+- Ensure workflow completed successfully
+
+**Problem**: Cannot pull package in workflow
+
+```yaml
+# Solution: Login to registry first
+- name: Login to GitHub Container Registry
+  uses: docker/login-action@v3
+  with:
+    registry: ghcr.io
+    username: ${{ github.actor }}
+    password: ${{ secrets.GITHUB_TOKEN }}
+```
+
+#### Debugging
+
+- **Manual Dispatch**: Use `workflow_dispatch` for testing
+- **Log Analysis**: Review step outputs for error details
+- **Artifact Inspection**: Download build artifacts for verification
+- **Package Logs**: Check package activity in GitHub UI
+
+## Future Enhancements
+
+### Planned Features
+
+- **SLSA Integration**: Enhanced build attestation
+- **Dependency Review**: Automated dependency vulnerability checking
+- **Performance Testing**: Load testing integration
+- **Multi-environment Deployment**: Staging and production separation
+
+### Scalability Considerations
+
+- **Self-hosted Runners**: For resource-intensive jobs
+- **Job Parallelization**: Further optimization of concurrent execution
+- **Cache Optimization**: Advanced caching strategies
+
+## Docker Image Usage
+
+### Pulling Images
+
+Pull the latest image:
+
+```bash
+docker pull ghcr.io/<owner>/<repository>:latest
+```
+
+Pull a specific version:
+
+```bash
+docker pull ghcr.io/<owner>/<repository>:1.2.3
+```
+
+### Running Locally
+
+Run the container:

+  oci://ghcr.io/<owner>/<repository>:latest \
+  --owner <owner>
+```
+
+## Contributing
+
+When modifying workflows:
+
+1. Test changes using `workflow_dispatch`
+2. Ensure backward compatibility
+3. Update this documentation
+4. Follow security best practices
+5. Use semantic versioning for action references
+6. Test Docker builds locally before pushing
+7. Verify package permissions after changes
+8. Review CodeQL alerts before merging PRs
+9. Update query packs regularly for latest security rules
+10. Test configuration changes with `workflow_dispatch`
+
+## CodeQL Advanced Configuration
+
+### Custom Configuration File
+
+For complex CodeQL setups, use a configuration file (`.github/codeql/codeql-config.yml`):
+
+```yaml
+name: "CodeQL Config"
+
+# Disable default queries to run only custom queries
+disable-default-queries: false
+
+# Specify query packs
+packs:
+  - scope/go-security-pack
+  - scope/go-compliance-pack@1.2.3
+
+# Add custom queries
+queries:
+  - uses: security-and-quality
+  - uses: ./custom-queries
+
+# Filter queries by severity
+query-filters:
+  - exclude:
+      problem.severity:
+        - warning
+        - recommendation
+  - exclude:
+      id: go/redundant-assignment
+
+# Scan specific directories
+paths:
+  - internal
+  - cmd
+  - pkg
+
+paths-ignore:
+  - "**/*_test.go"
+  - vendor
+  - "**/testdata/**"
+
+# Extend threat model (preview)
+threat-models: local
+```
+
+Reference the config in your workflow:
+
+```yaml
+- uses: github/codeql-action/init@v3
+  with:
+    config-file: ./.github/codeql/codeql-config.yml
+```
+
+### Inline Configuration
+
+Alternatively, specify configuration inline:
+
+```yaml
+- uses: github/codeql-action/init@v3
+  with:
+    languages: go
+    config: |
+      disable-default-queries: false
+      queries:
+        - uses: security-extended
+      query-filters:
+        - exclude:
+            problem.severity:
+              - recommendation
+```
+
+### Scheduling CodeQL Scans
+
+Run CodeQL on a schedule for regular security audits:
+
+```yaml
+on:
+  push:
+    branches: [main]
+  pull_request:
+    branches: [main]
+  schedule:
+    # Run at 14:20 UTC every Monday
+    - cron: '20 14 * * 1'
+```
+
+### Avoiding Unnecessary Scans
+
+Skip CodeQL for specific file changes:
+
+```yaml
+on:
+  pull_request:
+    branches: [main]
+    paths-ignore:
+      - '**/*.md'
+      - '**/*.txt'
+      - 'docs/**'
+```
+
+### Analysis Categories
+
+Categorize multiple analyses in monorepos:
+
+```yaml
+- name: Perform CodeQL Analysis
+  uses: github/codeql-action/analyze@v3
+  with:
+    category: "backend-api"
+```
+
+### External Query Packs
+
+Use query packs from GitHub Enterprise Server:
+
+```yaml
+- uses: github/codeql-action/init@v3
+  with:
+    registries: |
+      - url: https://containers.GHEHOSTNAME/v2/
+        packages:
+          - my-company/*
+        token: ${{ secrets.GHES_TOKEN }}
+    packs: my-company/go-queries
+```
+
+### Query Suite Examples
+
+**Security-focused**:
+
+```yaml
+queries:
+  - uses: security-extended
+```
+
+**Quality and security**:
+
+```yaml
+queries:
+  - uses: security-and-quality
+```
+
+**Custom suite**:
+
+```yaml
+queries:
+  - uses: ./custom-queries/critical-security.qls
+```
+
+## Advanced Workflow Techniques
+
+### Workflow Commands
+
+GitHub Actions supports workflow commands for advanced functionality:
+
+#### Debug Logging
+
+Enable detailed debugging with the `ACTIONS_STEP_DEBUG` secret:
+
+```yaml
+- name: Debug step
+  run: echo "::debug::Detailed debugging information"
+```
+
+#### Annotations
+
+Create annotations for notices, warnings, and errors:
+
+```yaml
+# Notice annotation
+- run: echo "::notice file=app.go,line=10::Consider refactoring"
+
+# Warning annotation
+- run: echo "::warning file=main.go,line=5,col=10::Deprecated function"
+
+# Error annotation
+- run: echo "::error file=handler.go,line=20,title=Build Error::Missing import"
+```
+
+#### Grouping Log Lines
+
+Organize logs with collapsible groups:
+
+```yaml
+- name: Build application
+  run: |
+    echo "::group::Compiling Go code"
+    go build -v ./...
+    echo "::endgroup::"
+```
+
+#### Masking Secrets
+
+Prevent sensitive values from appearing in logs:
+
+```yaml
+- name: Generate token
+  run: |
+    TOKEN=$(generate_token)
+    echo "::add-mask::$TOKEN"
+    echo "TOKEN=$TOKEN" >> $GITHUB_ENV
+```
+
+#### Job Summaries
+
+Add Markdown summaries to workflow runs:
+
+```yaml
+- name: Test summary
+  run: |
+    echo "### Test Results :white_check_mark:" >> $GITHUB_STEP_SUMMARY
+    echo "" >> $GITHUB_STEP_SUMMARY
+    echo "- Total: 150 tests" >> $GITHUB_STEP_SUMMARY
+    echo "- Passed: 148" >> $GITHUB_STEP_SUMMARY
+    echo "- Failed: 2" >> $GITHUB_STEP_SUMMARY
+```
+
+### Environment Files
+
+Use environment files for dynamic configuration:
+
+```yaml
+# Set environment variable for subsequent steps
+- name: Set build info
+  run: |
+    echo "BUILD_TIME=$(date +'%Y-%m-%d %H:%M:%S')" >> $GITHUB_ENV
+    echo "COMMIT_SHA=${GITHUB_SHA:0:7}" >> $GITHUB_ENV
+
+# Use in later steps
+- name: Deploy
+  run: echo "Deploying $COMMIT_SHA built at $BUILD_TIME"
+```
+
+### Output Parameters
+
+Share data between steps:
+
+```yaml
+- name: Calculate version
+  id: version
+  run: echo "VERSION=1.2.3" >> $GITHUB_OUTPUT
+
+- name: Use version
+  run: echo "Building version ${{ steps.version.outputs.VERSION }}"
+```
+
+### Multiline Values
+
+Handle multiline strings safely:
+
+```yaml
+- name: Store API response
+  run: |
+    {
+      echo 'API_RESPONSE<<EOF'
+      curl https://api.example.com/data
+      echo EOF
+    } >> $GITHUB_ENV
+```
