"""
Test Quantum Orthogonal Executor (000→999)

Tests end-to-end query→verdict flow through parallel quantum execution.

Architecture:
- AGI Particle (111-333): Mind - Truth, Clarity
- ASI Particle (444-666): Heart - Peace, Empathy, Humility
- APEX Particle (777-888): Soul - Measurement collapse, final verdict

Key Difference from Pipeline:
- Sequential: 000 → 111 → 222 → 333 → 444 → 555 → 666 → 777 → 888 → 999
- Quantum: 000 → [AGI || ASI] → APEX → 999 (parallel superposition)
