Closures — reference table

Auto-generated by scripts/generate_closures_reference.py from the live closure registry (aeolus1d.closures.registry). Do not edit by hand — regenerate after adding or renaming a closure kind. A unit test (test_closures_reference_doc_in_sync) enforces this.

This page is the at-a-glance counterpart to the prose Closures page. For each closure family, every registered kind is listed alongside the schema fields the kind consumes (drives the inspector form factory's per-kind reveal), the integer dispatch code (used by the @njit kernels), and the spec class + file where the kind is registered.

Adding a new kind: see the aeolus1d-schema-extend checklist and the registration site in the file column.
