V5p27 — Mutual EM oscillation between knots (TQNT V5.33 reconception, first step of the chiral oscillation closure)

Within Topological Knot Quantum Theory (TQNT V5), neutral-meson oscillations L ↔ L* are tunnelling oscillations between a topological link L and its mirror L*, governed by a single chiral frequency omegachi = sqrt (Fₜorque / Ichi). Flavour and the CKM matrix are SM bookkeeping artefacts and play no role in TQNT. V5p27 is the entry point of the canonical oscillation series and corresponds to the conceptual reconception (commit 402b8ce) introduced by the author: the EM field of each knot torques its entangled partner, replacing the earlier phenomenological scalar-prefactor ansätze whose Sum|log| had saturated at ~1. 05 dex on K0, D0, B0, Bs0. Earlier phenomenological work has been moved to the archive folder docs/Archivesᵣecherches/preᵣeconceptionV5p33ₒscillations/ and is no longer cited as a baseline. Mechanism (V5p27). A mutual coupling Jᵢj ∝ Lkₑff (Kᵢ, Kⱼ) is introduced between every pair of knot components of a link L. Each component's chiral oscillation is now driven not only by its own scalar prefactor but by the integrated EM torque of its partners. The resulting omegachi inherits a multiplicative correction depending on the linking structure of L. Status. V5p27 lifts the scalar plateau but does not yet close the four mesons: B0 remains the bottleneck because the pair-coupling alone does not capture the three-body imbalance of asymmetric triplets. The full closure is reached in three further steps: V5p28 — collective inertia via linking number (zero free parameter). V5p29 — three-body multiplicative renormalisation that closes Sum|log| to 8 × 10-4 dex on K0, D0, B0, Bs0.
