+#### 7.1 Code Style & Linting with Ruff ✅
+- ✅ Created `pyproject.toml` with Ruff + mypy configuration
+- ✅ Created `.pre-commit-config.yaml` with Ruff hooks
+- ✅ Updated `requirements-dev.txt` (replaced black/isort/flake8 with Ruff)
+- ✅ Formatted all code with `ruff format` (25 files reformatted)
+- ✅ Fixed linting issues with `ruff check --fix` (41 auto-fixes)
+- ✅ Removed unused variables (prices, deals_per_quarter, unique_quarters)
+- ✅ Fixed missing trend_direction in LiquidityMetrics return
+- ✅ Set up pre-commit hooks (run in GitHub Actions as PR checks, not locally)
+- ✅ Created `.github/workflows/code-quality.yml` for automated PR checks
+- ✅ All 302 tests still passing after formatting
+- 📋 Mypy type checking (deferred - needs systematic type annotation fixes)
+
+**Phase 7 Results:**
+- ✅ Modern code quality with Ruff (10-100x faster than black+isort+flake8)
+- ✅ GitHub Actions PR checks prevent quality regressions (non-blocking locally)
+- ✅ Consistent formatting across entire codebase
+- ✅ Only 7 minor style suggestions remaining (not errors)
+- ✅ All tests passing (302 passed, 1 skipped)
