# Phase 1, Week 1, Day 1: Greenfield Project Kickoff Plan
## Morning Session (9:00 AM - 12:00 PM)
### Hour 1: Project Setup & Repository Creation (9:00-10:00 AM)
1. **Create new repository structure**
- Initialize `card-creation-v2/` directory alongside existing project
- Set up git repository with initial commit
- Create directory structure matching architecture plan:
```
card-creation-v2/
├── src/
│ ├── domain/
│ ├── data/
│ ├── services/
│ ├── infrastructure/
│ └── cli/
├── tests/
├── docs/
└── scripts/
```
### Hour 2: Development Environment Setup (10:00-11:00 AM)
2. **Initialize Python project with Poetry**
- Create `pyproject.toml` with project metadata and dependencies
- Set up virtual environment with Python 3.11+
- Install core dependencies: polars, pydantic, typer, pytest, mypy
3. **Configure development tools**
- Set up pre-commit hooks (black, ruff, mypy, pytest)
- Create `.gitignore` for Python projects
- Configure IDE settings (if using VS Code: create `.vscode/settings.json`)
### Hour 3: CI/CD Pipeline & Quality Gates (11:00-12:00 PM)
4. **GitHub Actions setup**
- Create `.github/workflows/ci.yml` for automated testing
- Configure matrix builds for Python 3.11, 3.12
- Set up code quality checks (linting, type checking, test coverage)
## Afternoon Session (1:00 PM - 5:00 PM)
### Hour 4: Core Infrastructure Foundation (1:00-2:00 PM)
5. **Configuration management system**
- Create `src/infrastructure/config/` module
- Implement environment-based configuration with Pydantic
- Set up logging framework with structured JSON output
### Hour 5: Domain Model Foundation (2:00-3:00 PM)
6. **Base domain types**
- Create `src/domain/models/` with core data classes:
- `Player`, `Team`, `Position`, `Hand` enums
- `PlayerId`, `TeamId` type aliases for type safety
- Implement value objects for baseball statistics
### Hour 6: Testing Framework Setup (3:00-4:00 PM)
7. **Test infrastructure**
- Set up pytest configuration with coverage reporting
- Create test fixtures for sample data
- Implement property-based testing setup with Hypothesis
- Write first domain model tests
### Hour 7: Documentation & Planning (4:00-5:00 PM)
8. **Project documentation**
- Create README.md with setup instructions
- Document architectural decisions in `docs/architecture/`
- Set up API documentation framework (Sphinx or MkDocs)
- Plan next day's tasks and blockers
## Specific Files Created on Day 1
### Core Project Files
- `pyproject.toml` - Project dependencies and metadata
- `.pre-commit-config.yaml` - Code quality automation
- `.github/workflows/ci.yml` - Continuous integration
- `README.md` - Project documentation
- `src/infrastructure/config/settings.py` - Configuration management
### Domain Models (Starter Set)
- `src/domain/models/__init__.py`
- `src/domain/models/player.py` - Player data class
- `src/domain/models/enums.py` - Position, Hand, Team enums
- `src/domain/models/types.py` - Type aliases and value objects
### Test Foundation
- `tests/conftest.py` - Pytest configuration and fixtures
- `tests/domain/test_player.py` - First domain model tests
- `tests/infrastructure/test_config.py` - Configuration tests
## Success Criteria for Day 1
✅ New repository created with clean architecture
✅ Development environment fully configured
✅ CI/CD pipeline running and passing
✅ First domain models implemented with tests
✅ Code quality tools enforced
✅ Team can clone repo and run tests successfully
## Dependencies & Prerequisites
- Python 3.11+ installed
- Git access to create new repository
- GitHub account for CI/CD setup
- IDE configured for Python development
## Risks & Mitigations
- **Risk**: Tool configuration conflicts
**Mitigation**: Use Poetry for dependency isolation
- **Risk**: Team environment differences
**Mitigation**: Containerized development option in Week 2
This Day 1 plan establishes the foundation for a high-quality, maintainable greenfield rebuild while ensuring the team can immediately start productive development.
