+# Layering — Data Model vs DCM (superseded)
+
+**Superseded 2026-07-23 by [`layering.md`](layering.md)**, which restates this boundary in
+current vocabulary (UDLM substrate vs DCM realization) and carries the deferred Higher-Order
+Model rationale. This file remains as a filename target for the historical
+[`00-split-manifest.md`](00-split-manifest.md); do not extend it.
