🚀 Bootstrap Gowlin (教練) Repository - Alpha Development Foundation

Summary

This PR establishes the complete foundational infrastructure for Gowlin, an
open-source LLM agent autograder. This bootstrap implementation provides a production-ready development environment
with comprehensive tooling, documentation, and CI/CD pipeline while clearly communicating the project's alpha
development status.

What is Gowlin?

Gowlin means "instructor" or "coach" in Cantonese and Mandarin. Like a patient coach providing consistent guidance,
Gowlin aims to provide automated, reliable feedback to developers learning to build production-ready AI agents.

🎯 Key Achievements

• Data Models: Complete Pydantic models for submissions, missions, and evaluation pipelines

✅ Development Infrastructure

• Python 3.12+ Requirement: Enforced across all environments for security consistency
• Quality Tools: Ruff (linting/formatting), Pyright (type checking), Bandit (security)
• Testing Framework: Pytest with 62%+ coverage, including unit and integration tests
• Pre-commit Hooks: Automated quality checks with trailing whitespace/EOF fixes

✅ Security-First CI/CD Pipeline

• Multi-platform Testing: Ubuntu, macOS, Windows with Python 3.12 matrix
• Security Scanning: pip-audit and Bandit with hard failures on vulnerabilities
• Code Quality: Comprehensive linting and type checking in CI
• Coverage Reporting: Codecov integration with fail-safe configuration
• Documentation: Automated MkDocs builds with GitHub Pages deployment

✅ Comprehensive Documentation

• Development Status Transparency: Clear alpha warnings throughout all documentation
• Architecture Documentation: C4 model diagrams and ADRs for key decisions
• Development Guide: Complete setup instructions with security best practices
• Project Structure: Detailed file-by-file documentation of entire codebase

✅ Production-Ready Deployment Configs

• Containerization: Multi-stage Dockerfile with Docker Compose orchestration
• Kubernetes: Complete manifests with Kustomize overlays for dev/prod environments
• Monitoring: Prometheus/Grafana stack with custom dashboards and alerting

🔧 Technical Highlights

Package Configuration (pyproject.toml)

• Hatchling build backend with modern Python packaging
• Optional Dependencies: Separate [dev] and [docs] dependency groups
• Tool Integration: Centralized configuration for all development tools
• Metadata: Proper classifiers including Chinese language support

Security Implementation

• Dependency Scanning: pip-audit with hard CI failures as explicitly requested
• Static Analysis: Bandit integration with comprehensive rule coverage
• Git Hooks: DCO sign-off automation for contribution compliance
• Secrets Management: Automated scanning and validation workflows

Development Experience

• Setup Script: One-command development environment setup with Python version validation
• VS Code Integration: Automated workspace configuration with recommended extensions
• Local Validation: All tools (ruff, pyright, pytest) verified to pass locally before PR

🎯 Current Implementation Status

✅ Alpha Phase - Completed

• Project infrastructure and tooling
• CLI framework with basic commands
• Data models and configuration system
• Comprehensive testing and documentation
• Production-ready CI/CD pipeline

🔄 Architecture Defined - Needs Implementation

• Evaluation system (framework exists, needs concrete evaluators)
• Sandbox system (Docker/Firecracker integration planned)
• OpenTelemetry observability (setup complete, needs utilization)

❌ Future Development

• Mission system and LLM integration
• Web interface and authentication
• Production deployment and scaling

🔒 Security & Quality Assurance

• All security vulnerabilities MUST be fixed (hard CI failures as requested)
• Type safety: Comprehensive annotations with strict Pyright checking
• Code quality: Ruff linting with extensive rule coverage
• Testing: Unit and integration tests with coverage reporting
• Documentation: Every component documented with clear development status

🧪 Validation

All tools pass locally:

• ✅ ruff check src tests - All checks passed
• ✅ pyright - 0 errors, 2 minor warnings
• ✅ pytest - 50 tests passed, 62.64% coverage
• ✅ Security scans - No vulnerabilities detected

📋 Files Added/Modified

New Files

• Complete source code structure (src/gowlin/)
• Comprehensive test suite (tests/)
• Documentation website (docs/, mkdocs.yml)
• Deployment configurations (deployment/)
• Development scripts (scripts/)
• GitHub workflows (.github/workflows/)
• Project documentation (DEVELOPMENT_STATUS.md, PROJECT_STRUCTURE.md)

Key Configurations

• pyproject.toml - Complete project configuration with alpha status
• .github/workflows/ - Security-first CI/CD pipeline
• .pre-commit-config.yaml - Automated quality checks
• scripts/setup-dev.sh - One-command development environment setup

🚧 Important Notes

⚠️ This project is in ALPHA DEVELOPMENT - APIs may change significantly
⚠️ Not ready for production use - Core features still being implemented
⚠️ Security-first approach - All vulnerabilities must be fixed before merging

Test Plan

• Clone repository and run ./scripts/setup-dev.sh
• Verify all commands work: gowlin --help, gowlin config
• Run test suite: pytest
• Validate CI pipeline passes all checks
• Review documentation builds correctly
