 ## Authors and contributors
 
-The author of the current `4.0.0-beta.2` dataset release is:
-
 - **Trang Bui** — dataset creator, benchmark and environment designer, release
   maintainer, and author of the current four-domain beta release.
-
-The planned Track B expansion includes:
-
 - **Tran Ngoc Cam Nguyen** — planned domain lead for **Multi-hop Knowledge** and
   **Document/Media**.
 
-The planned domains are not included in `4.0.0-beta.2`. Accordingly, the DOI
-for this beta should use the current-release author list. Tran Ngoc Cam Nguyen
-will be added to the author list of the new DOI when those domain artifacts,
-live trajectories, review records, and release metadata are published. No
-ORCID is currently recorded; ORCID is optional. See [`AUTHORS.md`](./AUTHORS.md)
-for the versioned authorship record.
