The authoritative Lean definitions are in: SE/Transformation/Relation/Composition.lean and SE/Transformation/Reference/Composition.lean.

The reference registry mirror is in: reference/composition-rules.toml.

Generated data is in: data/transformation/composition-registry.json.

Effect-level necessary conditions are formalized separately in: SE/Transformation/Effect/Composition.lean.

They constrain possible restoration and inverse-like behavior; they do not derive the declared composition relation.
