# CI/CD Workflow Fix Summary

## Issues Fixed

### 1. Outdated GitHub Actions Versions

Updated all GitHub Actions to their latest stable versions:

- `actions/checkout@v3` → `actions/checkout@v4`
- `actions/setup-python@v4` → `actions/setup-python@v5`
- `actions/cache@v3` → `actions/cache@v4`
- `codecov/codecov-action@v3` → `codecov/codecov-action@v5`
- `github/codeql-action/upload-sarif@v2` → `github/codeql-action/upload-sarif@v3`
- `pypa/gh-action-pypi-publish@v1.13.0` → `pypa/gh-action-pypi-publish@release/v1`

### 2. Context Access Warnings

Removed explicit `CODECOV_TOKEN` reference in workflow. The Codecov action now works without requiring a TOKEN_REMOVED for public repositories.
