2//! Numerical linear algebra with explicit execution and failure contracts.
3//!
4//! Default: dependency-free, synchronous host FP64. No GPU tensor is implicitly
5//! downloaded and no existing ruda-tensor LU entry point is replaced.
6//! Optional `tensor`: native FP32 small batched LU/QR/Cholesky/eigen/CG kernels.
7//! `sparse` adapts ruSPARSE CSR; `collective` adapts existing ruCCL host TCP.
8//! Host SVD, complex decompositions, sparse LU and reverse-mode pullbacks are
9//! dependency-free. These APIs report limitations rather than densifying or
10//! changing the execution backend silently.
11//!
12//! This is an experimental numerical baseline, not LAPACK/cuSOLVER API parity.
13//! Dense inputs are nonempty, finite, row-major matrices; views also permit
14//! explicit positive strides and transposition. Numerical rank/pivot decisions
15//! use the supplied tolerance and do not estimate a condition number.
