 ## Testing and Quality Gates
 
 - Python minimum version: 3.11.
+- For Python-related commands in this repo, use the project virtual environment binaries (for example `.venv/bin/python -m pytest`, `.venv/bin/python -m ruff`, `.venv/bin/python -m pyright`).
 - PR-required deterministic test harness must complete under 10 minutes wall clock (prefer under 5).
 - Required PR checks:
   - `ruff check`
