 ## [Unreleased]
 
+### Changed
+
+- Updated the installed and exact CI-tested `openstatspec/spss-sav` codec from
+  3.0.2 to 3.0.3, and aligned the reported engine identity and codec
+  documentation with the separately versioned OpenStatSpec package.
+- Made the transformation capability boundary explicit: the current PHP API uses the package-local legacy `openstatspec-transformation-plan-v1` contract and does not yet claim official Transformation Plan or SPSS Frontend profile 0.1/0.2 conformance.
+
 ## [0.4.0] - 2026-07-31
 
 ### Added

 ## Purpose and boundary
 
+> Status: this PHP layer currently uses the package-local legacy contract
+> `openstatspec-transformation-plan-v1`. It does not claim conformance with
+> OpenStatSpec Transformation Plan or SPSS Frontend profile 0.1 or 0.2.
+> Migration to official 0.1 is required before the additive 0.2 conditional
+> profile can be implemented or claimed.
+
 The transformation layer applies small, deterministic edits to an existing
 OpenStatSpec dataset. Its canonical `TransformationPlan`, validation, and SQL
 executor do not depend on SPSS, Stata, SAS, or another statistics package.
