3 All moving coordinates and finite parameters

Let x,R∈T2x,R\in\T_2 be a detector rotor and a new reference rotor, and set X=x−R(mod2)X=x-R\pmod2. Let Z,S,C∈RZ,S,C\in\R, and retain the original 255 differential source coordinates u∈1⊥⊂R256u\in\one^\perp\subset\R^{256}. The unknown normalized qubit/reference vector is ψ\psi, with exactly conserved projectors P0+P1=IP_0+P_1=I. Set p=∥P1ψ∥2p=\norm{P_1\psi}^2. The target projector P1tarP_1^{\rm tar} is an orthogonal projector with ∥P1−P1tar∥≤10−4\norm{P_1-P_1^{\rm tar}}\le10^{-4}, and ptar=∥P1tarψ∥2p_{\rm tar}=\norm{P_1^{\rm tar}\psi}^2. Both act as the identity on any admitted inaccessible reference factor. That reference is an internal Hilbert-space factor and introduces no additional guidance coordinates. Thus ∣p−ptar∣≤10−4|p-p_{\rm tar}|\le10^{-4}. The periodic classifier uses the centred cell coordinate u=((X−o)/h) mod 1∈[−1/2,1/2)u=((X-o)/h)\bmod1\in[-1/2,1/2): it is zero for ∣u∣≤1/4|u|\le1/4 and one otherwise, with a fixed boundary convention.

Set

N=256,h=1/128,K=238,ηt=2−16,ηp=2−17. N=256,\quad h=1/128,\quad K=2^{38},\quad \eta_t=2^{-16},\quad\eta_p=2^{-17}.

Let m=mxmR/(mx+mR)=αK/h2m= m_xm_R/(m_x+m_R)=\alpha K/h^2. Independently choosing

mx,mR∈[1.998,2.002]K/h2 m_x,m_R\in[1.998,2.002]K/h^2

ensures α∈[.999,1.001]\alpha\in[.999,1.001]. Nominally m=252m=2^{52} and mx=mR=253m_x=m_R=2^{53}. The other masses are

Ms=1018,M∈[.99,1.01]1018,μ∈[.00999,.01001],MC=108. M_s=10^{18},\quad M\in[.99,1.01]10^{18},\quad \mu\in[.00999,.01001],\quad M_C=10^8.

The retained source has κs=2.5 1043\kappa_s=2.5\,10^{43} and frequencies Ωk=1013sin⁡(πk/256)\Omega_k=10^{13}\sin(\pi k/256). It is a spectator Hamiltonian, not a field generator in this redesign.

Let S5(z)=10z3−15z4+6z5S_5(z)=10z^3-15z^4+6z^5. The even period-one UηpU_{\eta_p} equals z2z^2 for ∣z∣≤1/2−ηp|z|\le1/2-\eta_p and has positive-cap derivative

Uηp′(z)=2z[1−S5((z−1/2+ηp)/ηp)]. U'_{\eta_p}(z)=2z\left[1-S_5((z-1/2+\eta_p)/\eta_p)\right].

It is C3C^3, nonnegative, and bounded by 1/41/4. Define

Vi(X)=giK2Uηp(X−oh−i2−di),gi∈[.999,1.001],∣di∣≤.01. V_i(X)=\frac{g_iK}{2}U_{\eta_p}\left(\frac{X-o}{h}-\frac i2-d_i\right), \quad g_i\in[.999,1.001],\quad |d_i|\le.01.

The common origin oo is arbitrary. The relative sector offsets and gains can vary independently in these intervals; arbitrary nonperiodic site defects are not admitted.

For B9(a)=126a5−420a6+540a7−315a8+70a9B_9(a)=126a^5-420a^6+540a^7-315a^8+70a^9 on [0,1][0,1], with constant extensions, put

b(a)=LB9((a−a0)/wb),y=Z−z0, b(a)=L B_9((a-a_0)/w_b),\quad y=Z-z_0,
W0(a,y)=y22μ,W1(a,y)=(y−b(a))22μ−μb′′(a)(y−b(a)/2). W_0(a,y)=\frac{y^2}{2\mu},\qquad W_1(a,y)=\frac{(y-b(a))^2}{2\mu}-\mu b''(a)(y-b(a)/2).

The finite writer family is

L∈[23.99,24.01],∣z0∣≤.001,v∈[127,129],λ∈[.99999,1.00001],a0∈[1.2299,1.2301],wb∈[.03999,.04001]. \begin{gathered} L\in[23.99,24.01],\quad |z_0|\le.001,\quad v\in[127,129],\quad \lambda\in[.99999,1.00001],\\ a_0\in[1.2299,1.2301],\qquad w_b\in[.03999,.04001]. \end{gathered}

Its launch momentum is MvλMv\lambda. Spring coefficient 1/μ1/\mu and the scalar compensation are matched to the selected μ\mu. General symmetry-breaking or independently mismatched compensation errors are outside this theorem.
