 ## Recommended execution order
 
-1. Verify GitHub Actions `Tests` and GitHub to Hugging Face sync for WP3B UI integration commits.
-2. Ask the user/coordinator to verify the Hugging Face app shows `Extra exportcontrole` before downloads and that downloads remain available.
-3. After v12.6 is verified, close v12 Review UX and begin v13 UI integration for Scrub Key JSON export.
+1. Start v13 Scrub Key JSON export UI only after coordinator approval.
+2. Keep v13 UI integration sequential because it may touch the same review/export flow.
+3. Preserve v12 export semantics unless a future workpackage explicitly changes them.
