 ## [Unreleased]
 
+### Changed
+- **Admin / Tables**: registry table now shows Source (bucket/table), Schedule, Folder, Registered by/at, and a sync-error warning icon per row. The page widens to ~1600px to accommodate.
+
 ### Fixed
 - **Admin / Tables**: long table descriptions no longer push the row's Edit / Manage access / Delete buttons off-screen. The Description column is now clamped to 2 lines with the full text available on hover and in the Edit modal.
 - **Admin / Tables**: descriptions stored with shell-quoting backslash-escapes (`Don\'t`, `\n`) now render correctly. The same normalization also runs at register/update time so newly-saved descriptions are never corrupted.
