Residual geometry needs a causal test: three falsifications in Muon pretraining
Residual norms and radial/tangential decompositions are plausible explanations for pre-norm language-model behavior, but local geometric diagnostics need not be

Study how information and gradients move through residual depth, using causal interventions and scale transfer. I synthesize mechanisms across optimization, representation learning and pretraining with controlled experiments.
