### Rationale for this change When first reading the Variant encoding spec, it can be unclear that each Variant value begins with a single `value_metadata` byte composed of `value_header` and `basic_type`. This can be confusing, especially since “metadata” is also used to refer to the dictionary metadata structure. The spec already uses the term `value_metadata` in prose, so labeling it clearly in the layout diagram helps reinforce understanding and reduce ambiguity. ### What changes are included in this PR? - Added a clarifying comment (`<-- value_metadata`) to the value layout diagram to explicitly indicate that the first byte is `value_metadata`. ### Do these changes have PoC implementations? N/A — documentation-only change, no impact on implementations. -- This is an automated message from the Apache Git Service.
