# Story 1.1: Initialize Python Project Structure

Status: Done
Created: 2025-10-28
Epic: 1 - Project Foundation & Core SDK Generation

## Story

As a developer,
I want a properly structured Python project with modern tooling,
so that the SDK has a professional foundation and follows Python best practices.

## Acceptance Criteria

1. Repository created with `.gitignore`, `LICENSE` (Apache 2.0), and `README.md` skeleton
2. `pyproject.toml` configured with project metadata, dependencies, and build system (hatchling or setuptools)
3. Project structure created: `/` (source), `tests/`, `examples/`, `docs/`, `scripts/`
4. Python 3.10+ compatibility verified
5. Git repository initialized with initial commit

## Tasks / Subtasks

- [x] Create initial commit: `git commit -m "Initial project structure from cookiecutter"`
- [x] Verify commit: `git log --oneline`

## Dev Notes

### Architecture Alignment

**Build System:** hatchling (modern, pyproject.toml-native, fast builds)
- [Source: architecture.md - Decision Summary table, line 76]

**Package Manager:** uv (fast dependency resolution, lockfile support)
- [Source: architecture.md - Decision Summary table, line 77]

**Project Layout:** src-layout (prevents import issues, best practice)
- [Source: architecture.md - Decision Summary table, line 86]

**Python Versions:** 3.10, 3.11, 3.12 (modern type hints, active maintenance)
- [Source: architecture.md - Decision Summary table, line 84]

**License:** Apache 2.0
- [Source: architecture.md - Project Initialization, line 62]

### Project Structure Notes

The project follows src-layout as mandated by architecture:
```
supermetrics-sdk/
├── src/supermetrics/      # Source code (src-layout pattern)
├── tests/                       # pytest tests
├── examples/                    # Example scripts
├── docs/                        # Documentation
├── scripts/                     # Utility scripts
├── pyproject.toml              # Project config, deps, build
├── uv.lock                      # uv lockfile
└── .github/                     # GitHub templates
```
