 #### Update a Table
 
+The PUT request requires two values from a prior GET response:
+
+- **`baseTableVersion`** — use the `tableVersion` field from GET (after the first update this becomes a metadata file path, not `"INITIAL_VERSION"`)
+- **`tableProperties`** — must include all `openhouse.*` properties from the GET response merged with any user-defined properties; omitting them causes a 500 in the server's cross-cluster eligibility check
+
+First GET the current state:
+
+```
+curl "${curlArgs[@]}" -XGET http://localhost:8000/v1/databases/d3/tables/t1
+```
+
+Then PUT with the returned `tableVersion` and `tableProperties`:

 ```
