+### Canonical Semantics & Immutability
+
+**Schemas v1.0.0** are the canonical, immutable semantic layer of CommandLayer.
+
+The npm package (`@commandlayer/commons`) may advance within **v1.0.x**
+to deliver tooling, documentation, and distribution improvements —
+**without modifying schemas or semantic meaning**.
+
+• Canonical schemas: `schemas/v1.0.0/`
+• Schema immutability enforced via content addressing + checksums
+• Package versions may patch forward independently
+
+• Canonical branch: `main`
+• Canonical schema tag: `commons-v1.0.0-canonical`
+• Canonical schema CID: `bafybeigvf6nkzws7dblos74dqqjkguwkrwn4a2c27ieygoxmgofyzdkz6m`
