   6# P-001: Three Generations of Fermions
   7
   8Formalizes the RS derivation of why there are exactly three generations
   9of fermions (electron/muon/tau, and the three quark families).

  12- P-001: Why three generations of fermions?
  13
  14## RS Derivation
  15D = 3 spatial dimensions (from DimensionForcing) → cube geometry Q₃.
  16The cube has 3 pairs of opposite faces. Each face-pair corresponds to
  17one "generation" in the ledger's mode structure. Thus 3 generations.
  18
  19The framework does not predict 4 or 2; D=3 is forced, and 3 face-pairs
  20is the unique count for a 3-cube.

  40    In the RS framework:
  41    1. DimensionForcing proves D = 3 is the unique spatial dimension
  42       (linking, 8-tick, spinor structure).
  43    2. A D-cube has D pairs of opposite faces.
  44    3. Each face-pair corresponds to one fermion generation in the
  45       ledger's mode-counting (one independent "direction" of
  46       coherence per pair).
  47    4. Thus: 3 generations.
  48
  49    This is not a coincidence — it is forced by the same dimension
  50    argument that gives linking and spinors. -/
