conftest now derives a worker id from PYTEST_XDIST_WORKER, assigns a distinct (port1, port2) pair via env vars before importing test_config, and chdirs each worker into its own tmpdir at session start. udpproxy and keydb.py both read keys.tdb from cwd, so per-worker cwd is enough to keep workers' database state isolated. test_config exposes absolute KEYDB_PY / UDPPROXY_BIN paths so tests still resolve them after chdir. test_authentication switches all subprocess calls to KEYDB_PY.

Replace the bash logic in run_tests.sh with run_tests.py, which builds udpproxy and runs pytest twice (connections, then authentication) with optional -n J for pytest-xdist parallelism. run_tests.sh becomes a thin shim that activates the venv and execs the Python runner so existing CI and README invocations keep working. Add pytest-xdist to setup_ci.sh. The keys.tdb backup/restore dance in the old script is dropped: workers now use per-worker tmpdirs, so the repo-root keys.tdb is never touched.

GitHub-hosted ubuntu-latest runners have 4 vCPUs, and the new test harness supports pytest-xdist parallelism via run_tests.sh -j N. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
