decomposition against Di=(∂iW,∂iZ)D_i=(\partial_iW,\partial_iZ) in the μ\mu-weighted kinetic space. The sharp integration limit gives

AW0=160log⁡2−328/3,AZ0=1915/3−920log⁡2,Qωmin⁡g⟶212529−760log⁡2=96.0082846335…. A_W^0=160\log2-328/3,\quad A_Z^0=1915/3-920\log2,\quad \frac{Q\omega_{\min}}g\longrightarrow\frac{212}{529-760\log2} =96.0082846335\ldots .

The combined/scalar cost ratio tends to .7111023682….7111023682\ldots. These replace the constant-inertia values for this changed profile. At εp=.01\varepsilon_p=.01, analytic moment bounds evaluated with Arb give 95.93859<Qωmin⁡/g<96.1120995.93859<Q\omega_{\min}/g<96.11209. For fixed p,Q,σp,Q,\sigma and ωmin⁡\omega_{\min} the cost and velocities stay bounded as the layer narrows. They are initial-jet results, and gg is not the complete boost inertia mQmQ. For a nonzero smooth radial cutoff 0≤χ≤10\le\chi\le1, define gAjg_{Aj} by inserting χj\chi^j in each Gram integral. The fixed compact family's minimum uses gχ=gW12/gW2+gZ12/gZ2≤gg_\chi=g_{W1}^2/g_{W2}+g_{Z1}^2/g_{Z2}\le g and vA=−(gA1/gA2)p/gχv_A=-(g_{A1}/g_{A2})p/g_\chi. Arbitrary signed cutoffs are not included.

Physical rotations obey (Bx)⋅∇W=0(Bx)\cdot\nabla W=0 and (Bx)⋅∇Z=BZ(Bx)\cdot\nabla Z=BZ for antisymmetric BB, so support orbital and intrinsic angular charges cancel pointwise. Material coordinates retain the induced frame covector even at zero frame velocity. Coefficient forces remain: on the stated slice,

μWtt+12μ′(Wt2−∣Zt∣2)=q0′Qder,μZtt+μ′WtZt=0,Ft=b[∇⋅(q0hA)/q0−(q0′/q0)Wt]. \mu W_{tt}+\tfrac12\mu'(W_t^2-|Z_t|^2)=q_0'Q_{\rm der},\quad \mu Z_{tt}+\mu'W_tZ_t=0,\quad F_t=b[\nabla\cdot(q_0h_A)/q_0-(q_0'/q_0)W_t].

At s=1s=1, Wq0′/q0=(2+εp)/(2eεp)Wq_0'/q_0=(2+\varepsilon_p)/(2e\varepsilon_p) and μ′/μ\mu'/\mu diverges like 16/(eεp)16/(e\varepsilon_p). Bounded recoil cost therefore does not imply bounded acceleration or sharp-interface dynamics.

Explicit Positive-Entropy Competitors In The Rational Density Family

The following calculation uses the earlier rational density action, not the new plateau. In its 72 common- unit controls, NH=2,NL=1N_H=2,N_L=1, d=2,3,4,5,6,10d=2,3,4,5,6,10, ℓ=1,10,100\ell=1,10,100, η=0,1\eta=0,1, and both b0b_0 laws, change
