Every git invocation runs through a single blocking subprocess.run call in python_git/runner.py that always waits for the process to exit and closes its pipes before returning, so there is no long-lived Popen handle for a caller to forget to close (the root cause of GitPython's known fd/process leaks). Repo exposes status/log/diff/add/commit/push/pull/fetch, branch and remote management, and clone, backed by dataclasses in models.py. Covered by tests/test_repo.py, including an fd-count regression test. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
