 131/-! ## Connection to Consciousness Threshold -/
 132
 133/-- HYPOTHESIS: The consciousness threshold C = 1 emerges from φ-quantization.
 134
 135    The exact relationship needs derivation. Some possibilities:
 136    1. C = 1 is the point where J-cost integration over one octave equals unity
 137    2. C = 1 relates to φ^n summing to specific values
 138    3. C = 1 is forced by the 8-tick structure interacting with φ
 139
 140    This is marked as a hypothesis until the derivation is complete. -/
