Modules§

jet_algebra
The single shared Faà di Bruno / Leibniz combinatorial kernel (#1151).
jet_partitions
Bitmask-coefficient multi-directional jets used by marginal-slope and latent-survival row kernels.
jet_scalar
Order-specific Taylor-jet SCALAR algebras (#932 cutover, doc §A).
jet_tower
Taylor-jet tower algebra: write each family’s row log-likelihood ONCE, derive the entire RowKernel<K> derivative tower mechanically (#932).
nested_dual
Nested second-order forward-AD dual for FD-free high-order cross-checks (#932).
order2_graph
Compiled value/gradient/Hessian lowering for runtime row expressions.
probability
quantile
score_opt
Certified global optimization of one-dimensional scores on a bounded domain, together with the affine-pencil spectral profile shared by the Gaussian REML smoothing-parameter searches.
special
Scalar special-function primitives shared across the workspace.
