+Members with collaborator (Write) access push their own G-numbers from the bench repo
+(ask the owner on this dataset's Settings page for access):
+
+```bash
+python3 scripts/upload_assets.py --dry-run          # what would be uploaded
+python3 scripts/upload_assets.py --games G011,G013  # push specific games only
+```
+
+Only games containing real artifacts are uploaded (skeleton-only games are skipped),
+and uploads on disjoint games are safe to run concurrently.

 - The current skeleton contains empty placeholders (`.gitkeep`); real artifacts are dropped
