💻 What You Can Run RIGHT NOW

1. Test Components (No Setup Needed)

python scripts/test_dj_agent.py

Tests: Imports, action space, scheduler, policies, rewards
Time: 30 seconds
Result: ✅ Verifies all components work

2. Run Demo (No Serato Needed)

python scripts/demo_dj_agent.py

Shows: 30-second simulated performance
Output: Ghost-mode recommendations, energy/phase tracking
Time: 30 seconds

3. Profile Performance

python scripts/profile_dj_performance.py

Measures: Latency of all components
Target: < 8ms frame time
Result: Confirms real-time capability

4. Test OSC to SuperCollider

🎯 What Happens When You Set Up MIDI

After IAC Driver Setup (5 min)

python -c "import mido; print(mido.get_output_names())"
# Should show: ['IAC Driver Bus 1']

After Serato Config (10 min)

from computational_studio.studio.dj_agent import SeratoBridge

config = {
    'mode': 'midi',
    'midi_port': 'IAC Driver Bus 1',
    'map': {...}  # From dj.yaml
}

bridge = SeratoBridge(config)
# ✅ Serato MIDI bridge opened: IAC Driver Bus 1

# Send test message
bridge.send({'type': 'midi', 'message_type': 'note_on', 'channel': 0, 'note': 36, 'velocity': 127})
# → Serato Deck A plays/pauses

After First Live Run

cd computational-studio/studio
python runtime/engine.py

# You'll see:
# ✅ StudioEngine initialized
# ✅ DJ Agent initialized (mode=ghost)
# 👻 [GHOST] Would execute: LOOP_4_A at ψ=+8.2°
