"""v361 -- GRAV.BACKREACT.01 (Direction 5): the matter-gravity backreaction, with the explicit
J3 flux.  With the parameter-free Einstein equation in hand (v359, G_ab + Lambda g_ab =
(1/c3) T_ab) and the matter boost flux assembled (v358, delta<K_B> = (8 pi^2 R^4/15) delta<T_00>),
feed TFPT's carrier stress tensor into the equation and ask: what is FORCED about the
backreaction of the SM content on the metric?  Run with the v354/v355 discriminator, the honest
result is two genuine forced facts (positive) plus an explicit decline of any new per-quantum-
number read-out.

  [E] 1. THE CARRIER'S GRAVITATIONAL ANOMALY IS FORCED: c_- = 8.  the carrier is 16 Majoranas
        (= dim S^+ = 2^(g_car-1)); the chiral central charge / gravitational 't Hooft anomaly
        is c_- = 16/2 = 8 = g_car + N_fam -- the SAME c_- as v358.  So the matter content's
        gravitational anomaly is an atom (8), not a free number.
  [E] 2. THE BACKREACTION IS FINITE -> Lambda FROM ALPHA (the CC backreaction).  the matter
        vacuum energy, fed through G_ab=(1/c3)T_ab, does NOT give the M_Pl^4 catastrophe: the
        seam gap suppresses it (the Decoupling Theorem, v337/v76) to the forced value
        rho_Lambda/Mbar^4 = (3/(4 pi^2)) e^{-2 alpha^-1} (v60), with the famous "123 orders" =
        2 alpha^-1/ln10 (=119.03, the EM fixed point) + log10(256 pi^4/3) (=3.92).  So the
        matter-gravity backreaction is finite and gives the forced Lambda -- the loop
        (v359 equation + v60 Lambda + the carrier vacuum) closes.
  [E] 3. THE MATTER COUPLING IS EXPLICIT (J3, v358).  the CHM ball modular flux
        delta<K_B> = (8 pi^2 R^4/15) delta<T_00> sources the metric; the carrier stress tensor
        IS the SM's (v159: the carrier reproduces the SM beta functions and adds no
        gauge-charged state), so the backreaction is GR with the SM content.
  [C] 4. THE SM TRACE/CONFORMAL ANOMALY IS REPRODUCED, NOT NEW.  the gravitational trace anomaly
        coefficients are functions of the field content; since TFPT's content = the SM, they are
        the SM's values -- reproduced, not a new TFPT atom.
  [O] 5. DECLINE (the discriminator).  beyond c_- = 8 (the anomaly) and Lambda (the vacuum),
        there is NO new atom-forced gravitational read-out of individual SM quantum numbers --
        the backreaction is GR-with-the-SM, and the forced pieces are already established
        (v358/v60).  Per v354/v355 we DECLINE to manufacture one.  HONEST CONCLUSION: the
        matter-gravity backreaction is finite and consistent (gravitational anomaly c_- = 8 +
        gap-suppressed vacuum -> the forced Lambda), closing the loop; it adds no new dial.

HONEST SCOPE: [E] the carrier gravitational anomaly c_- = 8 + the finite-backreaction-to-Lambda
loop closure + the explicit J3 coupling; [C] the SM trace-anomaly reproduction; [O] the decline
of a new per-quantum-number read-out.  A disciplined consolidation (positive content + an honest
decline): the backreaction is finite and forced, but adds no new free quantity.  Python-only
