+  DSLO v0.6 is the canonical public-layer release of the Semantic Substrate
+  Specification. It defines the unified geometry governing meaning, invariants,
+  operator legality, drift dynamics, synthetic-pressure fields, institutional
+  deformation, dominant synthetic species, restorative-deficit dynamics, and the
+  human runtime manifold. This citation file provides structured metadata for
+  scientific indexing and cross-surface archival stability.
