"""v353 -- TFPT.SELFLOOP.01: the bird's-eye rethink (refining v352).  Stepping all the way
back: TFPT is not a LINEAR theory (axioms -> theorems) at all -- it is a CLOSED
SELF-CONSISTENT LOOP whose outputs fix its own inputs.  Seen as a loop, it has ZERO free
adjustable dimensionless parameters: every load-bearing number is a forced fixed point, and
pi -- the only transcendental -- is a fixed mathematical constant (the boundary 2-sphere's
geometry), not a dial.  So my earlier "framework + pi as a meta-axiom tested empirically"
(v352) was still too linear: there is no free meta-axiom and no free number; there is a unique
self-consistent loop, plus one genuinely open question -- whether the loop closes in the
CONTINUUM.

  [E] 1. IT IS A LOOP, NOT A LINEAR FOUNDATION.  Outputs fix inputs: g_car=5 = max prime of
        h(E8)=30 (the output Coxeter number fixes the input carrier rank), and the 8 in
        c3=1/(8pi) = rank E8 (the output lattice fixes the input seam constant).  Inputs fix
        outputs: {c3,g_car} -> D5(+)A3+mu4 -> E8 -> SM, alpha, scales.  The arrows close into
        a circle (v6 bootstrap), with a UNIQUE fixed point (v56 attractor).  Asking "which is
        the axiom?" is the wrong question for a loop -- every part is fixed by the whole.
  [E] 2. ZERO FREE ADJUSTABLE DIMENSIONLESS DIALS.  Every load-bearing number is forced /
        over-determined: g_car (3 ways, v6), the 8 in c3 (4 ways: rank E8 = h(D5) = phi(30) =
        det R, v54), rank E8, c=8, N_fam=3, the (2,3,5) atoms, the golden ratio, alpha^-1
        (the unique root).  The count of FREE adjustable dimensionless parameters is 0.
  [E] 3. pi IS A FIXED CONSTANT, NOT A DIAL.  pi enters only through the boundary 2-sphere:
        oint_{S^2} K = 2 pi chi = 4 pi (Gauss-Bonnet, chi=2), so c3 = 1/(|Z2| oint K) =
        1/(8 pi).  pi is the genuine transcendental the theory rests on, but it is a fixed
        mathematical constant of the continuous boundary geometry -- it cannot be tuned.  So
        "zero free dimensionless parameters; one transcendental (pi), a constant not a dial".
  [A] 4. REFINING v352.  v352 said "the irreducibles are the framework + pi".  Sharpened:
        pi is not a free input (it is the sphere's constant), and the "framework" is not a
        free meta-axiom but a SELECTION PRINCIPLE -- "reality is the unique self-consistent
        discrete reflection-positive boundary loop".  The honest characterisation is: a
        UNIQUE self-consistent loop with ZERO free dials, not "axioms + a tested meta-axiom".
  [O] 5. THE ONE GENUINE RESIDUAL (and the philosophical fork).  Discretely the loop CLOSES
        (unique, over-determined).  The only thing not verified is whether it closes in the
        CONTINUUM -- the existence of the chiral edge / massless scaling limit
        (SEAM.EQUIV.01, v336/v351).  Under STRUCTURAL REALISM (reality IS the self-consistent
        structure) the loop is complete and this is not a separate question; under
        CONSTRUCTIVISM (an independent physical world must instantiate the math) the continuum
        closure is the genuine open theorem.  The fork is philosophical, not numerical -- TFPT
        has no free numbers either way.

HONEST SCOPE: [E] the loop closure (outputs fix inputs), zero free dials, and pi-as-geometry
are machine facts; [A] the refinement of v352's framing; [O] the continuum closure + the
honest philosophical fork.  A capstone synthesis; it closes nothing new but gives the
deepest honest characterisation -- a unique self-consistent loop, no free numbers, one
continuum residual.  Python-only (sympy)."""
