Modules

assignment

Assignment gates and sparsity-prior helpers for the SAE manifold term. Mechanically split from sae_manifold.rs.

atom_codes

Per-point sparse atom codes for multi-manifold reconstruction.

basis

candidate_index

Sublinear candidate-atom index for active-set proposal (#985 part 1).

certificate_impls

Certificate implementations for the gam-sae certificate zoo (task #16; descended #1521).

certificates

Per-fit first-order optimality certificate for the SAE LAML criterion (issue #934).

chart_canonicalization

#1019 stage 1 / #2022 — arc-length (unit-speed) chart canonicalization for d = 1. The arc-length reparameterization is exact and IMAGE-FROZEN (reconstruction unchanged; the transport preserves BᵀSB), so it is a gauge RETRACTION along the Diff(M) orbit that leaves the data-fit AND intrinsic-smoothness objective invariant. #2022 promotes it from a post-fit pass to IN-LOOP enforcement (see unit_speed_retraction), applied at chart-refresh boundaries — never inside a line search, because it re-gauges t and thus changes the ARD coordinate prior energy (the term that pins the residual gauge to t → ±t + c). Post-fit canonicalization then reduces to a verification no-op. #1019 stage 1 — arc-length (unit-speed) chart canonicalization for d = 1 manifold atoms (circle and interval topologies).

chart_transfer

Pulled-back chart-to-chart transfer operators for frozen model components.

corpus

Streaming / out-of-core corpus driver for the SAE term (#973).

criterion_atoms

Criterion-as-atoms for the SAE LAML objective (issue #931, SAE pilot).

dictionary_artifact

Canonical dictionary artifacts (#2018).

encode

Kantorovich-certified encode atlas (issue #1010).

frames

gpu_kernels

hybrid_split

#1026 — load-bearing curved-vs-linear hybrid split for the fitted SAE dictionary.

identifiability

SAE identifiability primitives and partial-supervision gauge fixing.

inference

SAE-level inference instruments that descended into gam-sae during the #1521 crate carve (top of the DAG).

k_selection

Automatic dictionary-size (K) selection from the EV-vs-K frontier (#1026).

manifold

SAE-manifold term configuration.

row_jet_program

The SAE reconstruction row as a single Taylor-jet program (issue #932).

sparse_dict

Fixed-K sparse, minibatched SAE trainer (#1026, “collapsed linear lane”).

structure_harvest

#997 — the wiring seam between a fitted SaeManifoldTerm and the evidence-guarded move engine of gam_solve::structure_search.
