Step 1: Detect Environment

Run these checks in parallel:

# Python version
python3 --version

# Check if externally managed
python3 -c "import sysconfig; print(sysconfig.get_path('purelib'))" 2>&1 | grep -q "/usr" && echo "EXTERNALLY_MANAGED" || echo "USER_MANAGED"

# Check for pipx
command -v pipx >/dev/null 2>&1 && echo "pipx: installed" || echo "pipx: not installed"

# Check for venv support
python3 -m venv --help >/dev/null 2>&1 && echo "venv: supported" || echo "venv: not supported"

# Platform
uname -s

---

Step 2: Check Component Status

IMPORTANT: Run these checks sequentially, not in parallel. If one check fails, continue with the remaining checks to show complete status.

CRITICAL: Always check the venv, not system Python!

# Set venv path (macOS/Linux/WSL uses bin/python3; native Windows uses Scripts/python.exe)
VENV_PYTHON=~/.bitwize-music/venv/bin/python3
[ -f "$VENV_PYTHON" ] || VENV_PYTHON=~/.bitwize-music/venv/Scripts/python.exe

# Check if venv exists
if [ -f "$VENV_PYTHON" ]; then
    echo "✅ Venv exists at ~/.bitwize-music/venv"
