 - **Practice 1: Path-based trigger filtering**: avoids running Python CI when unrelated folders change.
 - **Practice 2: Lint + test stages in CI**: catches style and functional issues early.
 - **Practice 3: Coverage reporting in CI command**: makes test quality visible, not just pass/fail.
-- **Caching**: `actions/setup-python` Poetry cache enabled with lockfile-based invalidation.
+- **Caching**: `actions/cache` stores `~/.cache/pypoetry` and `app_python/.venv` using a `poetry.lock`-based key.
