PLI Candidate Note: Vector Winding Number and Three-Plane Anisotropy

This candidate note introduces a vector winding number hypothesis above candidate assumption A3 in the Pure Locking Inference framework. A vector winding number W_i = n_i m_i is defined on each Planck area element, preserving the integer nature of the original scalar winding number while adding spatial direction. Two types of three-plane components are introduced: signed net winding components and non-negative intensity components. The anisotropy parameter δ is defined without singularity as δ = (N_xy − N_yz) / (N_xy + N_yz), and is related to the mother black hole spin axis n_s through squared normal projections. The note explicitly states that the global scalar definition of N_eff remains open, and that the three plane components are directional candidates only, not a replacement for N_eff. Observable directions include CMB low-multipole axial bias, background magnetic field axis preference, and neutrino flavor asymmetry. Falsification conditions and experimental datasets are given. All new objects are marked as candidate assumptions or statistical candidates, not derived results. 中文摘要 本候选笔记在纯锁定推理框架的候选假设 A3 之上,引入矢量环绕数假设。每个普朗克面元上定义矢量环绕数 W_i = n_i m_i,它继承原始标量环绕数的整数性,同时增加空间方向。引入两类三平面分量:带符号的净环绕平面分量,和非负的强度平面分量。各向异性参数 δ 定义为无奇点形式 δ = (N_xy − N_yz) / (N_xy + N_yz),并通过法向投影平方与母黑洞自旋轴 n_s 关联。本文明确说明 N_eff 的全局标量定义仍然开放,三个平面分量只是方向候选,不是对 N_eff 的替代。可观测方向包括 CMB 低阶多极矩轴向偏心、背景磁场轴向偏好和中微子味不对称。给出了证伪条件和实验数据集。所有新对象均标记为候选假设或统计候选,而不是推导结果。
