- tests/test_metrics.py asserts the new linear-interp _percentile against hand-computed expected values (single value, two-value interpolation, endpoints, numpy-equivalent linear default, on-integer rank). - tests/test_proxy_pick.py exercises InstanceState LRU eviction and move-to-end on hit, plus session-affinity stickiness, the overload fallback, the active_p_offloads penalty, and lmetric scoring. The proxy is loaded by file path with stub fastapi/uvicorn/httpx modules so the suite runs without the FastAPI server deps installed. - pyproject.toml gets a hatchling wheel target and a [tool.pytest] section so `uv run --extra dev pytest` works out of the box.
