   7# Gray Code Chirality: The Geometric Origin of CP Violation
   8
   9This module proves that the canonical 3-bit Gray code cycle on Q₃ is **chiral**:
  10the directed walk distinguishes clockwise from counterclockwise traversal of
  11face boundaries. This chirality is the RS origin of CP violation.
  12
  13## The Central Insight
  14
  15The J-cost function satisfies J(x) = J(1/x) — it is perfectly symmetric
  16under particle↔antiparticle exchange. This symmetry IS CPT invariance.
  17
  18But the 8-tick recognition operator R̂ acts along a DIRECTED path through Q₃.
  19The Gray code walk [0,1,3,2,6,7,5,4] flips bits in the pattern [0,1,0,2,0,1,0,2].
  20This pattern is asymmetric: bit 0 flips 4 times while bits 1 and 2 each flip
  21only twice. The 4:2:2 split breaks the S₃ axis-permutation symmetry of the cube.
  22
  23Since face-pairs correspond to particle generations (ParticleGenerations),
  24different generations experience different numbers of flips during one 8-tick
  25cycle. This asymmetric coupling is the origin of flavor mixing (CKM/PMNS).
  26
  27## The Chirality Proof
  28
  29The cycle's chirality is measured by the **flip asymmetry vector**:
  30  Δ = (count(bit 0) − 8/3, count(bit 1) − 8/3, count(bit 2) − 8/3)
  31    = (4/3, −2/3, −2/3)
  32
  33This vector has nonzero norm, proving the cycle treats different axes
  34(= different generations) differently. Under cycle reversal, the winding
  35signs flip, confirming CP violation with CPT preservation.

 120CPT invariance corresponds to J-cost symmetry: J(x) = J(1/x).
 121CP violation corresponds to the chirality of the directed cycle.

 123dynamics (which direction we traverse) is not. -/

 152
 153Different particle generations correspond to different face-pairs of Q₃
 154(ParticleGenerations). The asymmetric bit-flip schedule means each generation
 155experiences a different number of "active" transitions per cycle. -/
 156

 158    for that axis determines how many times per cycle the generation is
