"""v303 -- FR.DYNAMICS.01: the discrete->dynamic lens on F_transfer. Asks the honest structural question: is the main-branch mechanism -- a gapped, positivity-preserving relaxation to a UNIQUE attractor (the local-averaging update m<-(A+2I)/4 m -> the E8 marks, gap 6 log(3/2)) -- also the shape of the four F_transfer instances, or are they an unrelated bolt-on? Answer (made precise + machine-checked below): ALL FOUR share the SAME shape -- a gapped contraction/flow to a unique attractor (Perron-Frobenius / Boltzmann H-theorem / RG fixed point). But only ONE of them, F_pole (Koide), has the SEAM rate: its contraction multiplier is exactly lambda_2 = (2/3)^6, the seam-clock subleading eigenvalue. The other three share the shape with EXTERNAL rates (thermal washout, cosmological friction, RG running). So F_transfer is the downstream manifestation of the one discrete->dynamic principle (the compiler fixes the discrete seed + integer kernel; a gapped flow carries it to the observable), and the theory's simplicity is preserved precisely because the external rates are honestly fenced (v187), not because they secretly reduce to the seam. [E] 1. F_pole (Koide) IS the seam dynamics. the Koide source->pole / branch relaxation is the Moebius map whose fixed-point multiplier is F'=(2/3)^6 = lambda_2 = the seam clock subleading eigenvalue (v82/v54); |F'|<1 => a UNIQUE attractor at the SEAM rate, gap 6 log(3/2). This instance literally runs the main-branch update. [C] 2. F_Boltzmann (eta_B) is a gapped positive contraction. the baryon asymmetry is the slow mode of a positivity-preserving Boltzmann operator; the washout kappa_f in (0,1) is a contraction toward equilibrium (H-theorem). The compiler fixes the discrete data (A_Lambda=10 in both M_1 and m~_1); the RATE is thermal, NOT the seam gap. [C] 3. F_relic (axion) freezes at an adiabatic fixed point. the misalignment field's comoving number density relaxes to a CONSTANT once H<~m_a (adiabatic invariant); theta_i = 3 pi/5 is the discrete seed. A relaxation to a unique attractor; the RATE is cosmological, NOT the seam gap. [I] 4. F_QCD (m_p/m_e) is an RG flow with the carrier UV attractor. the 1-loop flow with the carrier coefficient b_3 = -7 (asymptotic freedom) has the Gaussian UV fixed point as attractor; Lambda_QCD is the dynamically generated IR scale (dimensional transmutation). b_3 from the carrier; the FLOW is standard RG. [O] 5. VERDICT. one shape (gapped relaxation/flow to a unique attractor) underlies all four, = the main-branch discrete->dynamic principle; F_pole has the seam rate exactly, the other three share only the shape (external rates). F_transfer is not a bolt-on but the readout end of the one principle; honest boundary: TFPT does NOT claim the three external rates. Status: [E] the F_pole seam-rate identity; [C] the Boltzmann/relic relaxations (structural shape, external rate); [I] the QCD RG-attractor (carrier coefficient); [O] the unifying verdict. Demonstrates the SHARED shape; the quantitative solves stay the external modules (v164/v185/v212). Python (numpy); numerical/structural.
