   6# SDGT Forcing Theorem
   7
   8Proves that the sector-dependent generation torsion is FORCED
   9(not merely compatible) by three constraints:
  10
  111. **Partition Constraint**: The sum of three overlapping consecutive-pair
  12   spans must equal N₃ = 2D^D + 1 = 55.
  132. **Lepton Uniqueness**: Only {E_pass, F} = {11, 6} sums to W = 17,
  14   forcing the lepton sector to the middle position.
  153. **Charge Asymmetry**: |Q̃_up| ≠ |Q̃_down| forces unequal end spans,
  16   selecting the unique ordering (13, 11, 6, 8).
  17
  18## What This Proves
  19
  20Given the four step values {V+F-C, E_pass, F, V} = {13, 11, 6, 8}
  21and the constraint that three sectors partition N₃ = 55 via
  22overlapping consecutive pairs, the assignment:
  23  - Up quarks:   {13, 11}
  24  - Leptons:     {11, 6}
  25  - Down quarks: {6, 8}
  26is the UNIQUE assignment consistent with charge asymmetry.
  27
  28## What Remains
  29
  30The four step values themselves ({13, 11, 6, 8}) are not yet derived
  31from a single principle. They are verified to be Q₃ cell counts
  32(SectorDependentTorsion.lean), but WHY these specific counts appear
  33as generation steps is still open.

  43
  44For a sequence (a, b, c, d) with three overlapping consecutive pairs,
  45the sum of pair sums = a + 2b + 2c + d = (a+b+c+d) + (b+c).
  46If this must equal 55 and a+b+c+d = 38, then b+c = 17. -/

 114The integerized charges are |Q̃_up| = 4 and |Q̃_down| = 2.
 115Since 4 ≠ 2, the up and down sectors are physically distinct.
 116Equal spans would imply charge-degenerate mass hierarchies.
