Exact Jacobian spectra of dynamic residual mixers
A realized residual-stream mixing matrix and the Jacobian of its input-dependent mixing map are different operators. Building on established gating and attentio

Copy-stacking under Muon and WSD-to-zero: four-seed gains against an interpolated steady-time baseline
We test direct copy-stacking (G_stack; Du et al., 2024) in a new recipe: a Muon + AdamW model trained on a warmup-stable-decay schedule whose linear warmdown ov
