 ### Prerequisites
 
-**CRITICAL**: Always run dependency installation before any build or test operations:
+Preferred: use the reproducible venv workflow via the test script. This creates and reuses `.venv_ci` under the repo root.
 
 ```bash
-# Install testing and analysis dependencies (requirements.txt is empty)
-pip install pytest pytest-cov mypy pylint
+# Runs tests in an isolated venv (.venv_ci) and pins pytest
+./scripts/run-tests.sh
+```
+
+Alternative (local dev): create your own virtualenv and install dev dependencies.
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -U pip
+pip install -r requirements-dev.txt
