- meta/.pre-commit-config.yaml: move pytest-coverage hook to pre-commit stage - scripts/pytest_changed_packages.py: single batched pytest -n auto invocation with one --cov flag per affected python_pkg subpackage, wrapped in systemd-run --user --scope -p MemoryMax=4G -p MemorySwapMax=0 when available - python_pkg/steam_backlog_enforcer/tests/conftest.py: new autouse _no_real_sleep fixture patches time.sleep across game_install / library_hider / steam_api / _enforce_loop. Removes 3x 15s real sleeps in TestFinalizeCompletion that fired through _ensure_steam_running steam_backlog_enforcer test wall time: 33.97s -> 5.61s (xdist, no-cov) 5-package batched run: 732 tests in 1.37s @ 668% CPU Coverage stays at 100% on all affected packages.
