• Abstract: We extend the spin-vortex-induced loop-current (SVILC) qubit [Wakaura2017] and the 3-Layer Quantum Brain Hypothesis to engineered organic materials operated without any applied magnetic field. Four paths are proposed: (P1) a flavin--nitroxide radical-pair reservoir, (P2) a perchlorotriphenylmethyl (PTM) radical array in a covalent organic framework, (P3) the SVILC analogue on $κ$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Br (conditional on SVILC confirmation), and (P4) a Su--Schrieffer--Heeger soliton on trans-polyacetylene. We verify the eight SVILC conditions and benchmark five algorithms (QKAN, qDRIFT, control-free QPE, Shor--Regev, Bernstein--Vazirani) plus two ML tasks (spike prediction, MNIST) on a covariant-purification CQEC simulator. With up to 100 trials, paired Wilcoxon tests and Bonferroni correction ($α\!=\!0.05/44$), CQEC gains are significant ($p\!<\!10^{-5}$) for all 16 path$\times$algorithm pairs and peak at $γ\!=\!0.5$ with $ΔF\!=\!+0.303$ for Shor--Regev ($d\!=\!64$), directly confirming Petz recovery beyond the entanglement-breaking threshold. Bernstein--Vazirani yields a provable quantum advantage: P2--P4 reach CQEC-corrected one-query success rates $\ge\!0.95$ versus classical $2^{-n}$, a $7.6$--$31\times$ advantage for $n\!=\!3$--$5$ (toy-scale benchmark). A tight-binding simulation on the anisotropic triangular lattice reproduces the two-SVQ coupling-vs-distance behaviour of [Wakaura2017] and shows that an external feeding current amplifies the coupling by $\sim\!1.9\!\times\!10^{3}$, providing theoretical scaffolding for P3. We quantify the diarylethene photoswitch CZ fidelity ($F_\mathrm{CZ}\!\ge\!0.987$ for P2--P4) and compare projected manufacturing costs against five competing platforms, finding 10--40$\times$ cost and 10--200$\times$ power reduction.
