+# Visitor Claims Webframe Demo
+
+Dev/test integration for validating that GitBook/GBX passes adaptive visitor context into ContentKit webframes.
+
+The integration exposes one block, `visitorClaimsWebframeDemo`, which renders a self-contained webframe at `/webframe`. The webframe displays:
+
+- The full posted ContentKit webframe state.
+- `state.visitor`.
+- `state.visitor.claims`.
+- `state.visitor.isSet`.
+- Regular webframe `data` values, including `label` and `mode`, as part of the full state.
+
+## Test
+
+1. Enable and configure adaptive content for the target site/space.
+2. Install this integration in the target space.
+3. Add the **Visitor Claims Demo** integration block to a space page.
+4. Set visitor input/test values in the GitBook UI.
+5. Confirm the webframe displays `visitor.claims` and `visitor.isSet`.
+6. Open the browser console and check the `visitor-claims-webframe-demo: received state` log for the raw state object.
+
+If the webframe receives state without visitor context, it shows `No visitor context received.` while still rendering the full state JSON for debugging.

+summary: |
+    # Overview
+
+    This development-only integration renders a ContentKit webframe and displays the full state GitBook posts into it.
+
+    # How it works
+
+    Add the Visitor Claims Webframe Demo block to a space page. The webframe displays regular ContentKit webframe data alongside any visitor context injected by GitBook, including `visitor.claims` and `visitor.isSet`.
