"""v437 -- E8.DEGREE.JOINT.01: the two TFPT structural integers are JOINTLY forced as the
unique root pair of ONE quadratic built from two E8 degree-invariants, and all of E8's
combinatorics is fixed by its degree multiset alone.

This is a CONSOLIDATION of v6 (the rank-fill g_car+N_fam=rank E8=8), v66 (the degrees ARE the
compiler atoms), v355 (the forced collective invariants sum/prod of degrees) and v431 (the
{0,2}-mod-6 two-family ladder).  It RESPECTS the v354/v355 anti-numerology discipline: it adds
NO new per-degree physical coincidence -- the only genuinely new content is the JOINT repackaging
of two ALREADY-established constraints into one quadratic whose uniqueness locks both structural
integers at once.

  [E] 1. ALL OF E8 IS FIXED BY ITS DEGREE MULTISET.  From deg(E8)={2,8,12,14,18,20,24,30} alone:
         rank = #degrees = 8 (and 8 is itself the 2nd degree); h(E8) = max(deg) = 30; #positive
         roots = sum(exponents) = 120; #roots = 2*120 = 240; dim E8 = #roots + rank = 248;
         |W(E8)| = prod(deg) = 696729600; sum(deg) = 128 = dim S^+ (the spinor half of
         248=120+128).  Every E8 integer TFPT uses is a function of the degrees.
  [E] 2. THE JOINT QUADRATIC (the new lock).  The two TFPT structural integers (g_car, N_fam) are
         the UNIQUE root pair of  x^2 - (rank E8) x + (h/2) = x^2 - 8 x + 15 = (x-3)(x-5).  The
         coefficients are two E8 degree-invariants: sum of roots = rank E8 = 8 (the rank-fill, v6),
         product of roots = h/2 = 15 = g_car * N_fam (= half the Coxeter number 30, v431's
         2*g_car*N_fam=h).  So BOTH structural integers are forced together by rank and Coxeter
         number; {3,5} is the unique positive-integer factor pair of 15 with sum 8.
  [E] 3. THE THREE MAPPED DEGREES ARE THE CANONICAL ONES.  The 3 degrees feeding a primary readout
         (v354) -- {2, 8, 30} -- are exactly {min degree (quadratic Casimir), rank, max degree
         (Coxeter h)}: the three invariants every simple Lie algebra distinguishes intrinsically.
         g_car=5 is the max prime of h=30; N_fam=3=h/(2 g_car); both land in the joint quadratic.
  [E] 4. DISCIPLINE UPHELD (no new mining).  This adds NO new per-degree coincidence beyond the
         joint quadratic, which is the solution of two PRE-EXISTING constraints (v6 + v431).  The
         five non-primary degrees keep their v431 family homes; the v354/v355 line is not crossed.
