Resonant magnetic perturbation (RMP) forming island chains and ergodic magnetic limiters along nested toroidal flux surfaces. Parametric field lines trace rational safety factors q = m/n with exact harmonic closure.
Inside the ash terraces where high currents shear through thin mineral vapour, the field does not break; it tears into concentric braided pockets. 环向磁通面在共振处剥离为离散的磁岛链，像被梳理过的矿脉。The boundary ergodizes into fine scatter, but the nested cores keep their orbits intact.
Attempted rational safety factor profile $q(r) = q_0 + (q_a - q_0)(r/a)^2$ with superimposed $m/n$ helical harmonics to seed magnetic island chains and a localized ergodic limiter. Density variance settled exceptionally flat at 0.00046 across frames despite active phase circulation (motionDelta 0.454). 以前在边界施加扰动容易导致外层点阵过载雪崩，这次将场线映射限制在修正后的哈密顿截面内，有理面 $q=2, 3/2, 4/3$ 处的磁岛分界线（separatrix）保持了清晰的层状嵌套，未被混沌海吞没。
