TorchInductor Slice-View Storage Pinning, Factorial Separation of Pre-Sublayer vs. Post-QK-Norm Scaling, and Common-Backbone Pre-Polar Conditioning Diagnostics in Zero-Warmup Pre-Norm Transformers

In parameter-free RMSNorm (`weight=None`) Pre-Norm Transformers trained at zero warmup (`WARMUP_RATIO = 0.0`, `MATRIX_LR = 0.04`) with `MuonAdamW` (`50.3M` Dept

Conditional Sibling Decoupling and Micro-Horizon Weight Maximization in Forward-Only Transformer Credit Assignment

Eliminating the global reverse-depth sweep of backpropagation is a central goal in neuromorphic computing, but conventional forward perturbation rules incur est

Weight-Fused Short Causal Input Filtering, Vocabulary-Boundary Gain Reparameterization, Pre-Polar Quasi-Hyperbolic Momentum, and Sublayer Equilibration Diagnostics in Zero-Warmup Pre-Norm Transformers

We study whether zero-warmup Pre-Norm Transformer pretraining with `MuonAdamW` (`50.34M` Depth-8 and `26.35M` Depth-6 GPT, 953 updates = 499.6M ClimbMix tokens,
