   4# Coherence Exponent k=5 Uniqueness — Beltracchi Response §3
   5
   6From outstandingissues_response.tex:
   7
   8Two independent routes force k = 5, and they agree ONLY at D = 3.
   9
  10Route 1 (Fibonacci deficit):
  11  k_fib(D) = 2^D - D
  12  k_fib(3) = 8 - 3 = 5 = F₅
  13
  14Route 2 (Integration measure):  
  15  k_int(D) = D + 2
  16  k_int(3) = 3 + 2 = 5
  17
  18Agreement table:
  19  D=1: k_fib=1, k_int=3 — disagree
  20  D=2: k_fib=2, k_int=4 — disagree
  21  D=3: k_fib=5, k_int=5 — AGREE (unique!)
  22  D=4: k_fib=12, k_int=6 — disagree
  23
  24Lean theorems:
  251. k_fib(3) = 5, k_int(3) = 5 (agreement at D=3)
  262. k_fib(1) ≠ k_int(1), k_fib(2) ≠ k_int(2), k_fib(4) ≠ k_int(4) (disagreement elsewhere)
  273. D=3 is the unique dimension where they agree
  28
  29Master theorem: exponent_unique_at_D3 — k=5 is uniquely forced at D=3.

  31Lean status: 0 sorry, 0 axiom.
