Add CI/CD pipeline with GitHub Actions — lint, test, build, publish

[rudra496]

Summary

Set up a comprehensive GitHub Actions CI/CD pipeline for the project.

What to create

1. CI Workflow (.github/workflows/ci.yml)

on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with: { python-version: "3.12" }
      - run: pip install -e ".[dev]"
      - run: ruff check .
      - run: black --check .
      - run: mypy ai_trust_validator

  test:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, windows-latest, macos-latest]
        python-version: ["3.8", "3.9", "3.10", "3.11", "3.12"]
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with: { python-version: "${{ matrix.python-version }}" }
      - run: pip install -e ".[dev]"
      - run: pytest --cov --cov-report=xml
      - uses: codecov/codecov-action@v4

2. Publish Workflow (.github/workflows/publish.yml)

• Trigger on git tags (v*)
• Build package
• Publish to PyPI

3. PR Check Workflow

• Run on pull requests
• Validate code, check coverage threshold
• Block merge if coverage < 70%

Acceptance Criteria

• CI runs on push and PR
• Tests run on Python 3.8-3.12 across 3 OSes
• Lint + type checking passes
• Coverage reported
• Publish workflow ready for releases
• Status badges in README

Difficulty

Beginner — GitHub Actions configuration, well-documented patterns.
