# WizardMerge CI/CD Workflows
This directory contains GitHub Actions workflows for continuous integration and deployment.
## Workflows
### 1. Gated Tree CI/CD (`ci.yml`)
A comprehensive multi-stage pipeline with quality gates at each level.
#### Workflow Structure
The workflow implements a gated tree pattern where each stage (gate) must pass before the next stage begins. This ensures quality at every step.
```

#### Gates Explained
**Gate 1: Code Quality**
- Ensures code follows formatting and style guidelines
- Runs linters for C++, TypeScript, and Python
- Fast feedback on code quality issues
**Gate 2: Build Components**
- Builds all project components (backend, frontends)
- Verifies that code compiles successfully
- Only runs if linting passes
- Produces build artifacts for testing
**Gate 3: Testing**
- Runs unit tests for backend
- Verifies TLA+ formal specification
- Only runs if builds succeed
**Gate 4: Security Scanning**
- CodeQL analysis for security vulnerabilities
- Scans C++, Python, and JavaScript code
- Only runs if tests pass
**Gate 5: Integration Tests**
- Tests API endpoints
- Verifies component interaction
- Only runs if security scan completes
**Gate 6: Deployment Gate**
- Final gate before deployment
- Only runs on main branch
- Publishes test results to ci/test-results branch
#### Triggering the Workflow
The workflow runs on:
- Push to `main` or `develop` branches
- Pull requests targeting `main` or `develop`
#### Artifacts
The workflow produces the following artifacts:
- `backend-build`: Compiled backend binary
- `cli-build`: Compiled CLI frontend binary
- `qt6-build`: Compiled Qt6 frontend binary
- `nextjs-build`: Built Next.js application
- `tlc-results`: TLA+ verification results
Artifacts are retained for 1 day (except TLC results: 7 days).
#### Branch Protection
For a complete gated workflow, configure branch protection on `main`:
1. Go to Settings → Branches → Add rule
2. Branch name pattern: `main`
3. Enable "Require status checks to pass before merging"
4. Select required checks:
- `lint-cpp`
- `lint-typescript`
- `lint-python`
- `build-backend`
- `build-cli`
- `build-qt6`
- `build-nextjs`
- `test-backend`
- `test-tlaplus`
- `security-codeql`
- `integration-tests`
#### Local Testing
Before pushing, you can run checks locally:
**C++ Formatting:**
```bash
find backend frontends/qt6 frontends/cli -name "*.cpp" -o -name "*.h" -o -name "*.hpp" | \
xargs clang-format -i
```
**TypeScript Linting:**
```bash
cd frontends/nextjs
bun run tsc --noEmit
```
**Python Linting:**
```bash
pip install ruff
ruff check scripts/
```
**Backend Build:**
```bash
cd backend
./build.sh
```
**Run Tests:**
```bash
cd backend/build
./wizardmerge_tests
```
**TLA+ Verification:**
```bash
python3 scripts/tlaplus.py run
```
### 2. TLA+ Verification (`tlc.yml`)
Legacy workflow for TLA+ specification verification. This is now integrated into the main gated workflow but kept for compatibility.
## Best Practices
1. **Small, focused commits**: Easier to pass gates
2. **Run linters locally**: Catch issues before pushing
3. **Fix one gate at a time**: Don't move to next gate if current fails
4. **Monitor workflow runs**: Check Actions tab for failures
5. **Read security reports**: Address CodeQL findings promptly
## Workflow Philosophy
The gated tree approach ensures:
- **Quality**: Code is checked at multiple levels
- **Security**: Security scanning is mandatory
- **Reliability**: Only tested code reaches production
- **Fast feedback**: Early gates fail fast
- **Confidence**: All gates pass = deployment ready
## Troubleshooting
**Linting fails:**
- Run formatters locally and commit changes
**Build fails:**
- Check dependency installation
- Verify CMake configuration
- Review compiler errors
**Tests fail:**
- Run tests locally to reproduce
- Check test logs in Actions tab
- Fix failing tests before proceeding
**Security scan finds issues:**
- Review CodeQL findings
- Address high-severity issues first
- Update dependencies if needed
**Integration tests fail:**
- Check if backend starts correctly
- Verify API endpoints
- Review server logs
## Future Enhancements
Potential additions to the workflow:
- [ ] Performance benchmarking gate
- [ ] Docker image building and publishing
- [ ] Staging environment deployment
- [ ] Production deployment with manual approval
- [ ] Notification on gate failures
- [ ] Automatic dependency updates
- [ ] Code coverage reporting
- [ ] Documentation generation and deployment
