Modules

fast_channel

Hand-speed single-channel Faà di Bruno (#932 “unified source, fast as hand”).

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.

paired_timing

The speed-gate harness (#932). It ships in this library because the integration tests of other crates measure with it, and a #[cfg(test)] item cannot cross a crate boundary; no product artifact links it, and the paired_timing_report example is the reachability root that says so to a dead-code sweep keyed on artifact symbol tables (one such sweep deleted the harness, every gate that called it and every hand opponent those gates raced). One way to measure “does A beat B”, for every speed gate in this workspace.

probability

quadrature

Deterministic quadrature primitives shared across model and solver crates.

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.

serial_dependence

Dependence-corrected summaries of a serially correlated sample.

special

Scalar special-function primitives shared across the workspace.
