ref: N/A

Summary

• add a repo-local ordered quality gate for rank_llm
• enforce Ruff, offline tests, then MyPy in hooks and PR CI
• introduce an initial strict MyPy scope for the modern CLI/API surface

Why

• rank_llm previously had Ruff-only hook/CI enforcement and no static type gate
• pushes could succeed locally without running the same test/type sequence the repo now expects

Validation

• .venv/bin/python -m ruff check .
• .venv/bin/python -m ruff format --check .
• .venv/bin/python -m mypy
• .venv/bin/python scripts/quality_gate.py
• .venv/bin/python -m pre_commit run --all-files
• .venv/bin/python -m pre_commit run --hook-stage pre-push --all-files

Follow-ups

• expand the strict MyPy scope in subsequent stacked PRs to retrieval, server, scripts, training, and other legacy surfaces
