 ## Versioning Policy
 
-- Each schema lives at a **fixed, immutable path** (e.g. `schemas/vitals/v2.0.json`).
-- Breaking changes introduce a new file (`v2.1.json`, `v3.0.json`), **never** mutate an existing one.
-- Releases are tagged: `vitals/v2.0`, `vitals/v2.1`, etc.
-- Consumers should pin to a **specific commit SHA** for immutable builds (Yocto),

+- **Versioned filenames:** Each schema and example file is named with its version (e.g. `v2.0.json`, `v2.1.json`). When a new version is released, create new files with the updated version in the filename. Do not overwrite or mutate existing versioned files.
+- **Immutable contracts:** Never change a published schema file. Breaking changes require a new versioned file (e.g. `v2.1.json`, `v3.0.json`).
+- **Release workflow:** Use the `release.yml` GitHub Actions workflow to tag and release new schema versions. Tags should match the version (e.g. `vitals/v2.1`).

+### CI Validation
+
+Every push and pull-request runs `.github/workflows/validate.yml`, which uses [AJV CLI](https://github.com/ajv-validator/ajv-cli) to validate every example payload in `examples/` against its corresponding schema in `schemas/`. The workflow automatically checks all versioned schemas and examples, ensuring that the example and the schema never diverge.
+
+### Release Workflow
+
+To release a new schema version:
+1. Add new versioned schema and example files (e.g. `v2.1.json`, `v2.1.example.json`).
+2. Run the `release.yml` workflow from the GitHub Actions tab, specifying the new version (e.g. `v2.1`).
+3. The workflow will tag the release and create a GitHub Release entry.
