ANU Quantum Entropy + Destructive Interference

Quantum-inspired path validation using phase masks:
  Valid paths → e^{i0} = +1 (constructive interference)
  Invalid paths → e^{i*pi} = -1 (destructive interference)

Pipeline:
  1. Quantum seed (entropy source)
  2. Superpositioned candidates (multi-path)
  3. Oracle validation (Z3/SPARK/Lean)
  4. Phase mask application
  5. Resolved state (only valid paths survive)

Key math:
  Phase mask: valid → e^{i0}=1, invalid → e^{i*pi}=-1
  Quantum perturbation: val *= 1.0 + strength * (seed_byte/255 - 0.5) * 2
  Cancellation: invalid candidates get negative weight → not selected
  Pipeline soundness: only states with oracle=True returned
