+| `related`                  | object        | A general-purpose object describing **direct relationships** to other containers. All fields inside `related` are **arrays of DIDs**, supporting multiple links per relation type. This allows open-ended semantic extension by agents. |
 | `related.previous_versions` | array(string) | One or more container DIDs this container supersedes. Enables version branching and merging.   |
 | `related.in_reply_to`       | array(string) | DIDs of containers this one replies to. Used for multi-source reasoning or discussion threads. |
