📝 Walkthrough

Walkthrough

A GitHub Actions CI workflow was added to automatically run pytest on all pushes and pull requests, with concurrency management to cancel redundant runs. The README was updated with a brief section documenting the CI integration.

Changes

CI Workflow Setup

Layer / File(s)	Summary
Workflow Implementation .github/workflows/ci.yml	New CI workflow triggers on push to master and all pull_request events. Includes concurrency control with cancel-in-progress: true. Single pytest job on ubuntu-latest that checks out code, sets up Python 3.12 with pip caching keyed to requirements.txt, installs dependencies, and runs pytest --tb=short -q.
Documentation README.md	New "Continuous integration" section documents that pytest runs on every push and pull request on Ubuntu with Python 3.12 via GitHub Actions.

17-23: Consider updating GitHub Actions to latest major versions.

Both actions/checkout@v4 and actions/setup-python@v5 are valid for May 2026, but newer versions are available: checkout@v6 (latest v6.0.2) and setup-python@v6 (latest v6.2.0). Python 3.12 is supported through October 2028 and works correctly with the current action. Update to v6 for the latest features and security improvements.
