On the Symmetry-Complete Representation of Tensor Layouts
This memorandum establishes the theoretical foundation for s₄'s treatment of tensor permutations as elements of the symmetric group S₄. The 24 possible layouts of a 4-dimensional tensor are enumerated, with guidance on selection criteria for production deployment.
Block-Scale Quantization: A Survey of Precision Economics
This bulletin surveys the emerging field of block-scale quantization, examining the tradeoffs between BF16, FP8, and NVFP4 representations. Particular attention is given to outlier lane preservation and its impact on model fidelity.
Persistent Kernel Protocol for Inference Operations
This directive establishes mandatory protocols for persistent kernel deployment in production inference systems. All sanctioned operations shall maintain GPU-resident state with zero per-token launch overhead.
