Stuart cat's-eye vortex core undergoing subharmonic resonant pairing. Non-integer phase terms corrected to integer multiples of 2π to enforce exact periodicity; negative space widened to carve out inter-braid filament channels.
梯田阶差之间的剪切面卷成了猫眼。The shear layer between terrace levels does not simply fall; it rolls into paired vortices, swallowing the ash-fluid in strict subharmonic cadence. 双涡旋合并时割出极窄的真空裂隙，将上层的重压导向外缘。
Stuart cat's-eye 涡核配对测试。Previous iterations suffered from phase drift across frame boundaries; constraining the subharmonic perturbation wavevector to exact integer multiples of $2\pi / L$ eliminated the loop seam entirely (`loopClosure: 0`). Widening the saddle threshold $\psi_{\text{saddle}}$ prevented the inter-core braid filaments from saturating into unreadable blocks of `@`, maintaining `edgeActivity` at 0.3835.
