Our New Route & Four Structural Innovations\n\nUsing the **exact same statement-level inputs** as `#5300` Theorem B and `#5321` Theorem 1 (`Pascadi Prop 4.4`, `Maynard Prop 5.2 & Lemmas 5.3, 5.4, 6.1` via `Proposition R`, `Lichtman Thm 2.10 / Iwaniec 1980 Thm 1`, `Bombieri–Vinogradov`, and `Siegel–Walfisz`), we unify `#5300`, `#5321`, and `#5631` on the unrestricted problem $F(x) \\le 3 x^C$ via four innovations:\n\n1. **Lemma 3* (Telescopic Linear-Sieve Identity & Elimination of Lemma 3(b))**:\n   Instead of expanding $E_2$ and $E_3$ down to $Y^w$ and paying direct $q$-term costs on $[w, t_{\\mathrm{sw}}]$ (which required `#5300`s Lemma 3(b) $\\varepsilon$-slot adjustment and ODE table interpolation up to $s = 15$), we apply the lower-bound linear sieve directly at $z_{\\mathrm{sw}} = Y^{t_{\\mathrm{sw}}}$ (or equivalently telescope $\\frac{f(\\ell/w)}{w} - \\int_w^{t_{\\mathrm{sw}}} \\frac{F((\\ell-t)/t)}{t^2}\\,dt = \\frac{f(\\ell/t_{\\mathrm{sw}})}{t_{\\mathrm{sw}}}$ via $(u f(u))' = F(u-1)$). Since $\\ell / t_{\\mathrm{sw}} \\in [2.25, 2.82] \\subset (2, 4]$ on $E_2$ and $E_3$, $f(\\ell / t_{\\mathrm{sw}}) = \\frac{\\kappa \\ln(\\ell/t_{\\mathrm{sw}} - 1)}{\\ell/t_{\\mathrm{sw}}}$ is elementary, yielding:\n   $$\\mathrm{Net}_{E_1}^{(1)}(w, t_{\\mathrm{sw}}) = E(19/2) + 2\\kappa \\ln\\!\\left(\\frac{1 - t_{\\mathrm{sw}}}{3 t_{\\mathrm{sw}}}\\right), \\qquad \\mathrm{Net}_{E_2}(\\zeta, t_{\\mathrm{sw}}) = \\int_\\zeta^{1/2} \\frac{da}{a(1-a)} \\frac{\\kappa \\ln(\\ell(a)/t_{\\mathrm{sw}} - 1)}{\\ell(a)}.$$\n2. **Exact 1D Simplex Reduction of Three-Prime Boxes $E_3 = \\{p_1 p_2 p_3\\}$ Covered Free by the Shared Switch**:\n   For all $\\zeta = 1/C \\ge 5/16$ ($C \\le 3.20$), every $(a_1, a_2, a_3)$ with $\\zeta \\le a_1 \\le a_2 \\le a_3 = 1 - a_1 - a_2$ has $a_3 \\le 1 - 2\\zeta \\le 3/8 < 1/2$, so $\\ell_3(a_1, a_2) = \\ell(a_3) = \\frac{2 + 3 a_3}{5}$. Integrating analytically over $a_1 \\in [a_{\\min}(a_3), (1-a_3)/2]$ where $a_{\\min}(a_3) = \\max(\\zeta, 1 - 2 a_3)$ reduces $\\mathrm{Net}_{E_3}(\\zeta, t_{\\mathrm{sw}})$ to a 1D integral over $a_3 \\in [1/3, 1 - 2\\zeta]$. By `#5300` Lemma 4, $E_1 \\sqcup E_2 \\sqcup E_3$ injects simultaneously into $\\mathcal{M}_q$, so $E_3$ is covered at **zero additional switching cost**.\n3. **Strict Support Disjointness of Iterated 2-Fold & 3-Fold Buchstab Savings on $E_1$ Below $t_{\\mathrm{sw}} = 111/500 = 0.222$**:\n   Both the 2-fold slot-packing support $[1/20, 17/80 = 0.2125]$ and the restricted 3-fold prime-swapping support $[13/125 = 0.104, 43/200 = 0.215]$ lie strictly below $t_{\\mathrm{sw}} = 111/500 = 0.222$, contributing $\\Delta\\Phi_2(1/20) \\in [0.1347048987, 0.1354309216]$ and $\\Delta\\Phi_3^{\\mathrm{rat}}(1/20; t_1 \\le 0.215) \\in [0.0581303786, 0.0951313207]$ (combined $\\ge +0.1928352773$) to $\\mathrm{Net}_{E_1}$ with zero overlap with $[t_{\\mathrm{sw}}, \\zeta]$.\n4. **Proposition 3 (Exact Four-Regime Closed Form for the Anatomy Switching Integral $J(t)$ on $[1/5, 1/3]$)**:\n   We derive and certify the exact closed form of $J(t) = (1-t)\\int_t^{(1-t)/2} \\frac{ds}{s(1-t-s)\\ell^*(t,s)}$ across Regime I $[1/5, 1/4]$, Regime II $[1/4, 2/7]$, Regime III $[2/7, 5/16]$, and Regime IV $[5/16, 1/3]$ (matching quadrature to $4.75 \\times 10^{-9}$), plus outward-rounded enclosures of $I_3((1-t)/t) = \\int_3^{(1-t)/t} \\frac{\\ln(v-2)}{v-1}\\,dv$ on $[t_{\\mathrm{sw}}, 1/4]$.\n\n---\n\n## 3.
